Floods, Egypt, and Good Questions

It's been an eventful couple of weeks here. The Front Range just got about a year's worth of rain in about four days. We were fortunately dry and warm in our house, but the roads were dangerous, so we holed up at home for the duration -- glad to have electricity, clean water, and enough food on hand -- and kept up with friends and acquaintances who were evacuating, digging out, and drying out.

I think this is in central Boulder. Here's the original, but be aware -- it will start a video automatically.

The flooding led to some interesting learning around here. T and I played an imaginary game in which he accidentally dropped a magical bucket of water that flooded the whole world. We played at being, and talked about, squid, sea snakes, some of the smallest sea creatures (plankton and coral), some of the fastest sea creatures (tuna), and how we'd be better off breathing with gills. T also asked where the ocean was deepest, and where in the world giant squid lived. We found the Mariana Trench and the Challenger Deep on our world map. We looked up giant squid and found out about where they've been seen (all over the world, pretty much) and how they swim. We also found the first video captured of a giant squid in its own habitat. The scientists in the video were hugely excited, and so was T!

When we were able to drive around again, we were at a Park Day, talking with friends displaced by the floods and seeking interim housing, when another thunderstorm rolled in. We quickly got to the car and started home. On the way home, as we had on the way, we watched for areas that were still flooded or showed signs of flooding (P spotted so much debris caught on one barbed-wire fence that it looked as if it were made of hay bales!), and we talked a little hydrology -- what runoff is, and how it starts to happen faster when the ground is already saturated from previous rains, which was why we were driving home instead of waiting the storm out at the park. We also talked about what to do in a flash flood situation -- getting to higher ground as quickly as possible, which for some people in the canyons meant grabbing only their shoes and each other and climbing a hill in their pajamas before their houses washed away.

We've been reading a lot from the Theodosia series of books about Egyptologists and Egyptian magic in Edwardian London. In those books and online, we read some details about how the ancient Egyptians made mummies of their dead. We talked about the concept of desecration, as we read a part of the story in which a mummy was unwrapped for the entertainment of guests at a party. The story compared this to digging up and undressing one's deceased grandfather. Perhaps the richest thing about the Theodosia books has been their unstinting vocabulary. In the past two weeks, P has learned an enormous number of words from context and from my explaining them as we read. Here's a small sampling, from the times when my notebook was nearby to jot down the juicy words and phrases (while most of these are from Theodosia, a few are from the Ranger's Apprentice series, which P is reading with UnschoolerDad):

* fete * champagne * desecration * lorgnette * ensorcelled * wreak/reek * codger * scrutiny * wrath * stroke * apoplexy * frippery * poltroon * stevedore * treason * sherry * sarcophagus * lavatory * comportment * contravention * impertinent * loathe * glower * discern * simper * disabuse * attributed * grimoire * understatement * mortification * dudgeon * rue the day * tumult * charlatan * wizened * calling card * score (20) * macabre * lumbered * gin * listed * ajar * nonplussed * supercilious * demur * dressed above his station * spats *

I had to look up a few of these myself! Fortunately we're reading library e-books on a Kindle, so definitions for most of them are as easy to find as pushing a few buttons, and the flow of the story is hardly interrupted.

Here's a sampling of what else we've been up to, by general subject areas:

Math, Spatial Learning, and Logic (and a little Reading)

Both kids have been playing a lot with Minecraft. UnschoolerDad (UD) had some time during the floods to set up a server where they could play together, and he included the ComputerCraft mod, so they can also program "turtles" (like almost everything else in Minecraft, they're cubical) to dig, farm, tunnel, or do other tasks. So far they've mostly seen what UD could make the turtles do. The kids themselves have been continuing to experiment with roller coasters made from mine carts and mine-cart tracks, including ordinary tracks, powered tracks (which can accelerate or brake the carts depending on whether they're on or off), and detector tracks (which are nice for setting off huge piles of TNT blocks and creating new valleys in which to build coasters!). T in particular has been experimenting in very detailed ways. I watched him build a stretch of track between two stops (blocks placed across the track) that used a dip in the tracks to accelerate carts toward and away from one of the stopping blocks. When he had a train of mine carts behaving one way, he'd replace one section of track at a time with a different type of track and see how it affected their behavior. This investigation is completely self-driven. When I watch him I'm reminded of some research I recently read about regarding toys and how kids use them. Apparently when researchers instruct kids in the proper way to use a toy, the kids play with it less and rate it as less enjoyable than when the approach is more discovery-based and open-ended. Minecraft is an incredibly open-ended set of tools and toys, and T is enjoying it and using it a lot!
On the reading side of things, T found out about using slash commands to change his game mode mid-game (from survival to creative and back again), and he's learning to recognize and type the appropriate commands. I tell him the letters to type when he asks, describing their position on the keyboard if he doesn't already know where to find them -- so he's getting some right-left practice here, along with letter recognition and learning some written words. He's asking me a lot to read him the names of items in his inventory so he can find the specific items (often potions, which mostly look alike) he wants to use, and he seems gradually to be recognizing some of the words himself.
T has been asking a lot of questions about adding small numbers, and also about doubling numbers again and again. I think many of these are motivated by watching the numbers of items change as he crafts items in Minecraft or organizes his inventory. P answers some of his questions, and seems to enjoy doing so.
T has also been enjoying making his character in Minecraft invisible (so only his armor shows) and then watching himself in third person while he builds things. This new point of view seemed a little challenging at first, but he's taken to it quickly and now gets around almost as easily with the third-person, varying-angle point of view as he does in first-person view.
P is building a lot in Minecraft, too. Recently she designed a cruise ship (grounded). It's very large and includes a secret door to a secret-agent office. She used sticky pistons to open the door.
Once or twice recently, P asked me for some practice at adding 2-digit numbers in her head. She did well, including with carrying (e.g., 68+17).
P was looking over my shoulder when I saw a friend's Facebook post of a 5-pointed star drawn using an equation in polar coordinates. She asked about it. I started explaining Cartesian and polar coordinate systems. She moved on quickly to other things, so she doesn't really get it yet, but we sowed a seed, I think.
Both kids played Robo Rally, a board game, with UnschoolerDad. I have not played this game personally, but he says it involves skills in common with programming (and since he makes his living programming and was largely self-taught, he should know). T asked to play it again a few days later.

Science

T has been asking for Magic School Bus chapter books pretty regularly for bedtime reading. He likes to interrupt with his own ideas and questions about the story and the real-life things it tells about. His recent reading has included books about food chains and food webs, and about dinosaurs and fossils.
With all the recent thunderstorms, we've had some good conversations about lightning. P and I talked at length about lightning rods (how they're constructed and why they work), and about why being inside a house or car is pretty safe in a lightning storm, as long as you're not in contact with the conductive elements of either. I talked about how both houses (because of their plumbing and wiring) and cars (because of their metal frames and body parts) act like metal cages, and how people have used metal cages (I couldn't think of the term Faraday cage at the time) to isolate people or objects from electrical hazards.
The kids and I watched a video about skeletal preservations (for museums and such). This included using dermestid beetles to clean all the flesh off the bones. This came up in a book I was reading, in a conversation with a taxidermist about how flesh-removal has progressed from boiling to beetles, so I told the kids about that too. I know all this made an impression on T, because he asked me to remind him of the name of the group of beetles, days later.

Another video showed us a blue button jelly which, though it acts a lot like a jellyfish, is actually a community of small animals serving specialized purposes. We compared this to coral colonies. And we enjoyed a video about basking sharks, the second-largest fish. This one blew me away -- their mouths are so big, you could almost fit a piano inside!

Another video was about the nature of pain: nociceptors, plus a lot of variables, including subjective ones like mood and previous experience.
We also watched a video about optical illusions, specifically those that make things of the same color appear to have very different hues or values.
A SciShow video told us about Evolutionary Life History Theory, which says that we have limited energy to spend on reproduction, and each species or individual must strike a balance between spending that energy on courtship and mating, and spending it on caring for young. Apparently a recent study has showed an inverse correlation in male humans between the size of a man's testes and the energy he spends caring for his children. SciShow's often on the colorful side with the terms used, so be warned if you're watching this with kids around:

Another SciShow video described three inventions or discoveries growing from work done on the International Space Station. One of these had to do with microbeads, which related back to my exploration with P of how color-changing Polly Pocket hair works!
And, of course, see above for science related to flooding.

History, Civics, Geography

We read a right about the Civil Rights movement in the United States, emphasizing cooperation between African-Americans and Jews. We talked about some of the things that were being protested, such as poll taxes and literacy tests, and about how new Voter ID laws can have a similar effect on the ability of people of color and poor people to vote.
P perked up when Syria was mentioned in our Theodosia reading (in an ancient context, there) and immediately identified it as a place with current conflict. We talked a little about why everyone is talking about Syria -- the regime's apparent use of chemical weapons, especially against civilians, and why chemical and biological weapons are taboo.
P and I had a brief conversation about the custom of wearing white at weddings. I mentioned that traditionally, wearing white was a symbol of purity or virginity for the bride. We went on to define virgin, and to talk a little about why virginity has been valued more for women than for men (because without modern paternity testing, it's much harder to determine who the father of a child is than who its mother is, because her having only one sex partner makes this simple, and because this becomes important if a man is expected to care and/or provide for his children but not for the children of other men).
And of course Theodosia gives us nice tidbits of English and Egyptian history and customs, sometimes explicity, and sometimes more implicitly, in the ways that characters treat each other.

Reading, Language

Lots of reading has been described above. Here's what's left over:

T ended up with a copy of Diary of a Spider as a prize from the library summer reading program. We enjoyed reading it, and his appreciation of it was enhanced by our recent reading of a Magic School Bus book about insects and spiders. He enjoyed the pictures -- there's something funny or interesting to notice in them on every page, independent of the text, so the book is very engaging.
One day T asked how to say "two" in Spanish, and P answered him correctly. That evening I read him a library book called Gracias, Thanks in both Spanish and English. He asked me to point at the words I was reading so he could see the Spanish and English text. He liked it more than he has liked bilingual books in the past. He also picked up on the theme of being thankful for everyday things small and large, and we talked about people and things we appreciate.

Other Things

T continues using the mini-trampoline a lot, especially on days when are stuck inside or otherwise not exercising in other ways.
We've had a couple of big pillow fights between me and the kids: we have a bag of small, light pillows that are great for throwing, and this gets us running around to pick them up as well. Sometimes I start a pillow fight when the kids are crabbing at each other, because I can usually get them to team up against me, and this shifts their interaction with each other positively.
P is taking a new (to her) recreational gymnastics class. It was touch-and-go at first in her new class, which takes place at a much noisier time in the gym than her previous aerial dance class. She's sensitive to very noisy environments and is more easily upset in them, and the first and second classes were emotionally very stormy for her. But after crying with me through most of the second class time, she had a good conversation with me about what was going on for her. I hadn't been aware that noise was such a big part of the problem. We talked about what would help, and now we try to make sure she's well rested and recently fed when she goes to gymnastics, and that she has some quiet time in the hour or two before the class, so she isn't already fed up with noise before she gets there. So far, so good -- after her most recent class she was very excited to have made a leap forward with her cartwheel skills. She's also looking much more confident on the beam than I've seen her in the past.

Camping Rocks!

This week we had our first camping trip as a family! I was pretty stressed about the preparations, but things worked out well. While we were at the camp, on day two, I finally had one of those moments when I realized all the necessary work had been done and that I could relax. (As you might imagine, these don't often happen at home; there's always something I could or should be doing!)

This was a group camping trip, and the kids had been enjoying playing with other kids, but it still seemed like they were missing the comforts of home (iPads, etc.) more than they were enjoying the camping trip. So I talked with a new friend who had grown to love camping as a child about what she had loved. And I remembered the good things about my camping trips as a Girl Scout. Having and helping build campfires was a big one. Being entrusted with a knife and learning to use it was another.

There was a campfire-building in the works for that evening, so I talked to the guy building it about bringing in interested kids on the experience, and he was game. We showed the kids (including P) how we were splitting cordwood into kindling and tinder with a hatchet. They didn't want to do that, but they enjoyed helping building the tinder/kindling structure of the fire. When it came time to light it, we gave each kid a thin wooden splint we'd split for the purpose, and then we lit the ends of their splints (none of them wanted to tackle cardboard matches this time, and I couldn't blame them, between the difficulty and the wind), and they lit the tinder and got the fire going. They all enjoyed that, and some stuck around to continue feeding the fire as it grew.

Also that afternoon, UnschoolerDad supervised as P used her pocket knife to strip the bark from a long, dead stick and smooth it, discovering the color variations beneath the bark and generally noticing about how the wood grew and what that meant for how it could be used. Some of P's friends came by the campsite and watched and talked. They were surprised that P had her own knife. I wonder if some other parents will be getting requests for sharp objects soon?

The kids' highlights from the trip had to do with sleeping out in a tent, being outside a lot, playing with friends, and having more attention from family and friends who were not as busy as usual. We also went on a modest hike, built fairy houses, and saw different ways people were cooking their food outdoors. We are considering one more trip before the winter sets in -- we'll see!

So, here's more about what we did and learned during the week:

Math and Spatial Learning

Both kids did a lot of Lego building this week. Some of the instructions were a little challenging for T, but he worked through his difficulties with occasional help.
The roller coaster building has continued in Minecraft, with variations including more powered tracks and powered mine carts (which burn coal to move on their own). The kids have also been watching Minecraft videos for inspiration, including a massive cube of TNT (decorated with other materials to make it look like the largest-ever single block of TNT) being built and detonated; a giant Earth globe; giant jet airplanes and sports cars, and probably more I didn't see at the time.
I've overheard T a few times, counting out loud while building things in Minecraft. I think he was going for specific dimensions on something he was building.
In a game of numeric one-upmanship on the way home from camping, both kids were using "infinity" as a number ("Mine is infinity times five!") We talked some about how infinity is more of an idea than a number. When T asks me if there's a number bigger than infinity, I reply that infinity is the idea that no matter how big a number you think of, there is a bigger one. But in the car, I couldn't resist getting into the game, so I said, "Mine is infinity to the fifth power!" Then I had to explain what I meant by that: an introduction to exponents. Now I'm hearing them crop up in the kids' conversations.

Social Studies (History, Geography, Civics, Economics)

I read an online primer on the current situation in Syria to UnschoolerDad. P listened and asked a few questions.
Around Labor Day, we watched a video about the origins of Labor Day as a holiday and what labor unions have done to improve working conditions for everyone. This comes up occasionally as we see updates on our local grocery store's attempts to organize, and on Wal-Mart's union-busting and other unfair labor practices.
T read One Hen again, about microlending and its role in building small businesses and self-sufficiency.
P asked for help finding Hawaii on the world map. She also asked about how to pronounce the names of several South American nations, wanted to know exactly what was meant by "America" on the map (we talked about a few different ways it's used), and wanted to know why world maps aren't round (we talked about what would be hard to see if a world map were simply a photo of one side of a globe).
As we drove back from camping, T wanted to know if we were back in our state yet. I explained that we hadn't left it; we'd only been in two counties, I think. When we got home we used Google Maps to look at our trip on various scales, from a map of the whole country, to a map of the state, to a map showing our route at full screen, to zooming in on our campsite and finding where we pitched our tent (and then doing the same for our house). I let him be in charge of the zoom level, because I know it's disorienting to me when someone else is zooming about faster than I can understand what I'm looking at.
Also see Reading below: Theodosia is keeping us learning.

Reading and Writing

We finished Theodosia and the Serpents of Chaos. This included some bits of early-20th-century culture in both Egypt and England. We read about open-air markets, beggars calling for baksheesh (alms), and about how archaeologists from colonial powers like Great Britain were accustomed to finding artifacts in other countries and taking them back to their home countries for display. We also talked a little about how some countries, more recently, have begun trying to get back their historical treasures that have been appropriated in this way.
P and UnschoolerDad finished The Burning Bridge, the second book in the Ranger's Apprentice series.
T enjoyed the rest of a Magic School Bus book about electrical storms.
On the camping trip, we started a Magic Tree House book about early explorers of the ocean on the HMS Challenger.
P wrote a short story to put in a book in Minecraft. She asked for spelling help when she needed it. She seems to care more about standardizing her spelling than she used to.
T and P both played with Scribblenauts, asking for spellings when they needed them. P is able to help T with some words. Both kids continue learning their way around a keyboard in this way, too.
T asked me about several words from Minecraft and what they really mean. These included ghast, blaze, and creeper. I was surprised that ghast is actually an English word (a transitive verb), albeit not commonly used.
We saw an old Schoolhouse Rock video about verbs. We tied it into a song I often sing to the kids at night: "Sing When the Spirit Says Sing." T likes to substitute action verbs (especially build) into this song. That gave us many more examples of verbs.

Science

In the Magic School Bus book on electrical storms, T learned about how lightning forms, what thunder is, how to count the distance to a lightning strike, lightning safety, and lightning rods, as well as a bit about atomic structure and electrons. (P's familiar with these from reading the same book before and from other experiences.)
A hummingbird hawk moth showed up in our front yard recently, enjoying some flowers. UnschoolerDad and I had never seen one, but it stuck around long enough for us and P to get a good look. We looked it up and found it was probably a white-lined sphinx moth, and that it was an example of convergent evolution with hummingbirds and some other groups of birds.
Several science videos were interesting this week: the Moon Illusion (covering many theories about the moon illusion, but not my favorite, so I explained that one too), first-ever footage of a deep-sea squid, how a pin-tumbler lock works, how bodies adapt to microgravity (and how that makes life hard upon returning to Earth gravity), and envisioning the age of the earth (compared to a calendar year, or to the life of a child from birth to the first day of high school).
While we were camping, the kids enjoyed finding different kinds of rocks and pounding some of them to powder, getting different colors of powder out of different rocks. They also learned why we shouldn't scrape or otherwise damage tree bark (the trees have a hard enough time with the elk scraping them). We speculated about why trees in thickets have more snapped-off branches, higher up their trunks, than trees standing alone or at the edge of the woods (trees may shed their lower branches when other trees are blocking sunlight reaching them, and focus their energy on the higher branches, which can get sunlight and produce food for the tree). We saw many kinds of mushrooms and talked about the need to know a lot more than we do about mushrooms before considering tasting any of them. We saw chipmunks harvesting, nibbling, and carrying off some of the mushrooms and not others, and wondered whether humans and chipmunks could eat the same kinds of mushrooms (and whether any harm would befall those chipmunks from experimentation, or whether they already knew their way around the local mushrooms). We saw and talked about how campfires start and burn, including the need for plenty of air (but not too strong a wind in the beginning) and smaller fuels to start with. We also covered campfire safety, including keeping fuels and ourselves clear of the fire and keeping a big bucket of water nearby. The kids had gone to bed by the time we were extinguishing the fire, but they've seen that on previous campfire occasions at church.
On the way home from camping, T spotted some kind of factory by the side of the road. He remembered a video we'd watched about how charcoal briquets are made and said the factory looked like it could be a charcoal factory. I had to agree that looked like a possibility based on the materials and machines we saw -- the kid has a good eye!

Odds and Ends

We enjoyed a bike ride one evening.
One day when I was practicing guitar, playing a song but not singing it, I heard P humming along with the right tune and even some good harmonies.
Both kids loved a video of Rowan Atkinson in a live performance with an invisible drum set. A linked video of Jerry Lewis using an invisible typewriter fell flat, even after an explanation of how old typewriters worked. Atkinson showed much more attention to detail and variety in his performance. I had to agree he was funnier than Lewis.

Six-Second Science Fair and color-changing Polly Pockets spark an eventful week of exploration and learning

Starting two weeks ago, I decided to try an idea gleaned from a local homeschoolers' email list, in a discussion about record keeping. One mom used a teacher's plan book to keep track of her kids' studies -- one column per kid. I used teacher plan books for four years as a secondary teacher (one column per class), and I'm comfortable with that format. The next day I saw a teacher plan book on the $1 rack at Target, so I bought it and gave it a try.

I set things up with one column per general subject area, so I could see how our activities and learning were balancing out across subjects. The first problem I noticed was that teacher plan books only go Monday-Friday! That's okay -- I had a column left over, so we use that for overflow: Saturday and Sunday activites, and anything I can't fit in the regular columns for the week.

I leave the plan book on a coffee table by the couch where I frequently take little rests during the day, so it's easy to jot down whatever's happened most recently. This is also nice because instead of being in front of my computer in the kitchen when I'm making notes, I'm closer to whatever the kids are doing, and off my feet!

So this week, my summary will be loosely organized by subject. Some things overlap -- we Read about Science or History, for example. It's all good.

Science

One morning, P brought me a small Lego construction: a buoy with a flag on top, easily recognizable. We tried floating it in a bowl of water, and it floated on its side. Throughout the day, both kids and I tried different things to try to get it to float upright: adding more weight on the bottom, etc. P found that it would float upright if she removed the sideways-pointing part of the flag, which was making its weight distribution asymmetric.
P asked me how her Polly Pocket's hair was able to turn pink when warm and purple when cold. I didn't know, so we looked it up online. We found two possible mechanisms: thermochromism and halochromism. P was game for an explanation, so I drew diagrams to talk about different colors of light having different wavelengths; constructive and destructive interference resulting in crystals looking the colors they do, and how a crystal whose plane spacing changes could look different colors as the path length difference for diffracted light changes. These were in ascending order of complexity, and I think P grasped about the first half. Then we looked at halochromism and looked up the materials typically used and their relevant stats, especially the melting point of dodecanol, which turns out to be very close to that of coconut oil! When the dodecanol is liquid, salts in the halochromic microcapsules are dissolved, which changes the pH of the package and results in the protonation (or loss of a proton) by a dye molecule, which changes color as a result. I put a small lump of solid-at-room-temperature coconut oil on P's fingertip, and we watched it quickly melt; so it was easy to see how a transition from ice water to warm breath could change the color of a doll's hair if it had halochromic microcapsules on board. Again, I think P grasped the melting point and solubility parts, but the finer points of pH-driven reactions are a bit beyond our current level.
We all watched a great video, which we found on thekidshouldseethis.com, full of 6-second science fair videos. One bit showed putting eggs into vinegar and dissolving the shells, so the eggs end up squishy sacs of yolk and white. P and I decided to do that, and watched the bubbling surfaces of the eggs. I know calcium carbonate was a major constituent of eggshells, so we also put a Tums in some vinegar to see if it would behave similarly, which it did (until the reaction stopped, probably because there wasn't enough vinegar in the little bowl we were using -- this led to a little talk about limiting reagents in reactions). I looked up the chemical reaction between calcium chloride and acetic acid, and P and I talked some about that, drawing diagrams of the molecules and noting which parts would dissociate or connect. The partial charges on the ions in the reactions needed more explanation, so I drew some atomic-shell diagrams to talk about why an atom might be inclined to gain or give up an electron. I used the ionic bonding of NaCl as an extreme example of this, and we found a cool video showing NaCl dissolving. The shape of the NaCl crystal in the video as it dissolved, first becoming pitted and then coming apart more completely, was reminiscent of what we'd seen in the dissolving antacid.

Meanwhile, we kept an eye on the eggs. They were brown eggs, and we were surprised to see that the brown color didn't go all the way through the shells, but was the first part to dissolve away, while there was still plenty of hard shell left. We wondered whether tasting the solution the eggs were in was okay, so we looked up the reaction products and researched the one that wasn't familiar, calcium acetate. Safe enough, we decided. The next day, when the eggshells were fully dissolved, I tasted them (we had one hard-boiled and one raw; I cooked the raw one first) and, based on my review of the experience (yuck; vinegary, but not in a pleasant way), P decided not to taste them.
We all read some Magic School Bus chapter books this week, about insects (predation, digestion, spider webs, compound eyes, speedy motion, and more) and electric storms (T only for this: cloud formation, types, and evolution; buildup of charges at top and bottom of a storm cloud; formation of hail).
P and T watched Magic School Bus videos about decomposition, eggs, and dinosaurs.
One day when he tired of Minecraft, T sat down with me to look at our big anatomy book. He wanted to see the heart, then the brain. We looked at the cardiac cycle and at the brain's sensory, motor, and language functions. Each time we saw a brain region on a diagram, I'd touch T's head in the corresponding place. He was telling me about some of the areas himself before we were done, so he was clearly engaged.
In conjunction with our atomic-shell diagrams, P and I looked at the Periodic Table of the Elements and talked about why it has the shape it does (outer electron shells accommodate more electrons, so more different elements go by as you fill them) and what it would look like if it didn't have to fit on a standard-shape piece of paper (lanthanide and actinide series inserted, making the table much wider).
Inspired by another 6-second science fair bit, P drew an arrow and wrote her name backwards (mirror-image) on a small piece of paper, and we held it behind a glass full of water, seeing how at short distance it magnified, while at greater distances the images were reversed. That called to P's prior experience with magnifying glasses.

Math and Spatial Skills

Both kids did a lot of building in Minecraft this week. One day I went to the basement for maybe half an hour to deal with laundry, and when I came back, both kids had built rather impressive roller coasters with mine carts! They spent hours over the next few days embellishing these, adding new shapes and underground sections, adding powered track sections to boost speed, playing with block foundations to adjust slope, and so on.
Both kids have also been experimenting with TNT in Minecraft. Simple experiments result in near-simultaneous explosions of multiple blocks, leaving a very satisfying hole in the ground. After watching a video about TNT cannons, P built one, using redstone wiring to produce a simultaneous explosion of a ring of TNT blocks, propelling her character (on a stone block in the center of the ring) straight up, well above the clouds. They do these tricks in Creative mode, so their characters don't get hurt by the explosions and so they'd have a ready supply of TNT.
T asked me one evening, while I was reading to him, to say what the page number said. It was 79, and he seemed amazed it was so high. In the days since, I've asked him about a few two-digit page numbers, and he has interpreted them correctly. For 41, he also thought about what it would be if the digits were reversed, but he needed me to tell him that 14 was fourteen.
P and I made a number line for T from string and construction-paper rectangles. It goes up to 21, which is his favorite number. We used paper color and other markings to facilitate skip-counting of evens, odds, fives, and tens. T likes it and has gone to it spontaneously a couple of times to count out loud and look at the numbers. We hope this will help him through the teens, which are a little hard to remember how to write, and where he usually skips a number or two when counting out loud.
When P and I were talking about constructive and destructive interference of light waves, we discovered she didn't really know what negative numbers were. So I drew a number line that went both ways and showed her how to add positive and negative numbers on it. She quickly grasped this, so I also showed her subtraction of positive and negative numbers, both on the number line and in algebraic notation. She got it easily. We also looked a bit at algebraic notation for variables (e.g., the many ways to write multiplication), and how to write and evaluate simple expressions with variables. During this whole process, I could see P getting excited about these concepts in the same way I remember doing when I first learned them. It was so much fun to share concepts I love and have P share the feeling!

Reading and Writing

We finished reading out loud the Olympian Gods section of D'Aulaire's Greek Mythology. Both kids still listen closely to this.
We checked out an e-book version of Theodosia and the Serpents of Chaos from our local library. P was delighted that we could do this late in the evening, when the library was closed, and without going anywhere. It's a book about the daughter of two Egyptologists who own a museum of antiquities in London, around 1900. We get snapshots of life in that period, bits of the political scene in Europe, bits of Egyptian history and mythology, and some British slang along with this interesting story. P was also delighted to see that my new Kindle has a built-in dictionary lookup function, so if a word is in its downloaded dictionary, we can just look it up as we're reading. There's a lot of good vocabulary in this book, so I pause to check if I think a word is unfamiliar to the kids, and give them a definition or explanation if they need it. Sometimes they ask, too, about unfamiliar words. Interestingly, Theodosia does not go to school -- her parents don't pay much attention to her, and when she didn't return to boarding school after a dreadful term there, they didn't force the issue. She is now an autodidact, well versed in Egyptian writing and magic from her readings in the museum library, and learning as she goes about Egyptian history.
P read quite a bit of Theodosia out loud as I was giving T a bath this week. I haven't heard her read out loud much recently (though she does read to T beyond my hearing sometimes), and I was pleased to hear her fluency and expression as she read.
UnschoolerDad has been reading more of The Burning Bridge to P.
See Science for Magic School Bus reading this week.
A local unschooler, considering buying tablets for her kids, asked about the differences between Minecraft versions for PC and tablet. P knows a lot about this, so she helped me write an email about the most important differences. The information was very useful to the person asking the question.
When we were having sandwiches for lunch with my parents visiting, and I was dealing with dietary differences for many people, P wrote a list of what she would like on her sandwich so I wouldn't get confused.

Social Studies: History/Geography/Civics/Economics

See Reading for what some of what we learned this week in history.
UnschoolerDad was on a business trip this week, so T and I took a look at our world map to see where he was compared to where we were.
One one longish drive home, P asserted that she already knew the rules of the road and just needed to learn how to drive when it was time. I asked if she would like for me to quiz her on that, and she said sure. So I did, and it turned out she still had some learning to do, though she has absorbed quite a bit. She enthusiastically talked laws and defensive driving with me the rest of the way home.
On the 50th anniversary of MLK's famous speech at the March on Washington, I didn't get it together to show them the speech, but at bedtime we talked some about what people were fighting for, and I sang them "We Shall Overcome" as one of their bedtime songs.
In connection with checking out e-books, P wondered why only one person could check out a given copy of an e-book at one time. We talked about the economics of publishing, and how publishers who have been making money on printed books still want to make money on library books (which they do, since the books can be lent to only one person at a time and eventually wear out and require replacement), and how those publishers have made e-book deals with libraries that mirror those for print books, because they're afraid they'll lose their revenue stream otherwise. We also talked about how, technically, e-books could be much more widely available, and how this would be desirable from the consumer's point of view, but might lead to problems for publishers.

Everything Else: Art, Music, PE, and Miscellaneous Learning and Exploration

With UnschoolerDad out of town and calling us most evenings, both kids have finally learned how to carry on a conversation on the phone! It's easy to forget how weird this situation is for little kids. It requires not only thinking about a person they can't see, but also thinking a little about that person's perspective: what would they be interested to hear about? What can they sense, and not, about your surroundings as you talk with them? P was pretty good at it already, but she's getting better, too.
P started a new weekly gymnastics class and is enjoying it.
T has been making good use of our mini-trampoline, jumping often when he has excess energy to burn.
I've been playing guitar and singing at bedtime most nights. P has been joining in as she learns songs, and also starting to harmonize a bit.
With my parents visiting, we rented a canoe and a paddleboat at a nearby lake and went boating for an hour. We saw little trees that had grown in the spring and early summer while the lake was empty, some of them now far out in the lake. We saw fish jumping and speculated about why there are many bubbly places in the lake -- oxygenation for the fish, perhaps, or maybe that's where the lake gets filled? P learned a little about how to cooperate in paddling a canoe.
P did some nice drawings while I read to her, working on shading to produce some three-dimensional effects in drawing hair in particular.
T came up with an original (I think) idea in Minecraft. Since some blocks stick to others sideways while others fall when unsupported beneath, he built a tall shaft for crushing things (chickens, mostly). It has windows on one side for putting in whatever he wants to crush. He puts a sticky stone block with some sand blocks on top of it near the top of the shaft, and then he destroys the stone block so the sand falls all the way down.

Snow Forts, Board Games, Handwashing in Space...

Time for another sampling of what we get up to in a month of unschooling!

Reading

One day we were having a particularly grumpy morning, and once I'd fed everyone and it was still going badly, I got myself and the kids all into the big bed with a stack of library books. We read about the Hindenburg, the fall of Troy, The Three Golden Oranges, how to make kites, and a bit about airships in general. P read a bit more of Savvy when she wasn't fully engrossed in the other stories, but that was a minority of the time. She's also been reading Savvy in bed some nights.

One night I was trying to get the kids to bed early because both had colds. We did toothbrushing and such right after dinner so we wouldn't leave it too late. When it was time to hop in bed, I said, "T, I have a book about volcanoes here!" (from the library). He replied eagerly, "I want to read it!" So all three of us read the book together, with many, many pauses for questions and for puzzling out the diagram of the Earth's tectonic plates and what their motions were. We talked about oceanic spreading centers (the mid-Atlantic ridge and the East Pacific rise) and how new seafloor forms there, and the abyssal hill shapes that form as the plates spread apart. We talked about earthquakes, volcanoes, and mountain building as activities that all are common along plate boundaries.
P and I read part of a graphic novelette (long for a picture book, but short for a graphic novel) about events in the Netherlands around World War II. I think it was going to intersect with the story of Anne Frank, but we didn't make it through before it was due back at the library.
I'm reading On the Banks of Plum Creek out loud to both kids. The Little House books are evergreen here!
After a couple of failures, I finally found an anatomy book aimed well for us. It includes the anatomy of various body systems in quite a nice level of detail, and it has sections on how body systems work and on common ailments. It's close to what I was looking for, a sort of owner's manual for the human body. It's missing a troubleshooting section, but the Internet's probably a more complete and up-to-date source for that than we'd find in a book, between WebMD, the Mayo Clinic, and many other sites of varying reliability. One day I was looking at a disarticulated view of the skull, and P asked me about it. We talked about skull sutures, and how many of them form well after birth, and how this relates to fontanelles, the safe handling of babies, and how strange their heads can look immediately after a vaginal birth. We also looked at the bones of the middle ear and how they connect to each other, the inner ear, and the eardrum.
At a 5-for-a-dollar children's book sale at a nearby library, we bought 51 books. The kids weren't into looking through the many tables, so mostly they sat and read together (P reading to T, or both looking/reading silently) while I picked out things they might like. For that price, you can do a lot of throwing everything to the wall and seeing what sticks! One great find was a 1962 volume from a Collier's junior collection. My parents had this collection as a companion set to the 1966 encyclopedia I grew up with. I have fond memories of the whole set. The volume we found, Gifts From the Past, contains long and short excerpts from classic novels -- Twain, Austen, Swift, Dickens, Kipling, Alcott, and more. They're mostly at a level (because of vocabulary and complex sentence structure, or archaic subject matter) that works much better read out loud, with chances to ask questions and discuss, than P reading to herself. I was surprised at how much the kids enjoyed the excerpts I've read to them so far (from Little Women, Tom Sawyer, and The Swiss Family Robinson). We decided to read Little Women out loud in its entirety, since we have a nice version with illustrations and P found it particularly entertaining. P noticed that one of the illustrations of the Marsh family, all gathered around Marmee in an upholstered chair, was strikingly similar to an illustration in Meet Molly, an American Girl book we found at the sale (set during WWII) that P has been reading on her own. We compared the two and wondered whether one might be a model for the other, or both based on some other illustration we haven't seen.

The set I had as a child. Gifts From the Past is #10.

Other books from the book sale that have seen some use already: a book on the musculoskeletal system; one on making and performing stage magic tricks; a long picture book entirely in iambic heptameter; several picture story books, including one detailing how to make a hat from wheat straw and an exquisitely illustrated version of The Emperor's New Clothes; a book of riddles (in the style of those in The Hobbit, rather than the usual childhood Q&A puns); and a Barbie book with cleverly-done sliding pieces that change the pictures.
T is interested in reading. He's noticing and paying attention more to how words on the page match up with what we read aloud, and when UnschoolerDad reads to him, T likes to read some of the words himself. It's fascinating to watch the interest unfold without direct instruction. We show T what words say sometimes, especially when he asks. Sometimes he wants to write something and has us write an example he can copy. Recently I was making signs for a cookie-selling booth, and he wanted me to pencil one for him to color in, too, so I did. When he's sitting next to me and playing on an iPad, he'll often ask which button does what he needs, and if I tell him what the right button says and how to spell it, he likes finding the right button by looking at the words on the various buttons. He plays a game called Kinectimals sometimes, and there's a screen in this game that tells you the status of the virtual animal you're playing with (Dirty, Lonely, Happy, Playful, etc.). Sometimes T holds up this screen and asks, "Is Sandy dirty?" He's usually right when he guesses.

Doing

P continues to enjoy playing Minecraft and researching how to do interesting things in the game. She watches videos on the Minecraft wiki and enjoys telling me about them. They show things like how to build an elevator using a quirk in the interface for using a boat; or another elevator design using sticky pistons to push stairs together. P has done most of her Minecraft play so far in Creative Mode, in which all basic resources are provided, so you can build at top speed; but lately she's been playing in survival mode (where you have to find your own resources for building and crafting things), and showing a lot of pride in the things she manages to build there. She still plays only in peaceful mode, with no monsters and therefore no dangers aside from falling or drowning (she's been steering clear of lava). From my experience in the game, I know that some useful objects can only be obtained by killing monsters, and some mineral resources can only be mined near lava. It'll be interesting to see how her risk tolerance within the game evolves if she continues playing in survival mode.
P and T have both given the mobile game Dragon Box a try. It's a game that introduces concepts related to simplifying algebraic equations, but in pretty non-mathematical looking form (unless, like me, you're a former math teacher who's played a lot with concrete and symbolic approaches, and not only the conventional abstract approaches). Gradually things get more complex, and more mathematical symbols get introduced. T reaches his frustration level pretty fast. P goes a little farther. It's fun to watch -- I actually improved my own scores in the game by watching what P had figured out.
I've been drying several different kinds of fruit in our dehydrator. T has been hesitant to try most of them, but P is enjoying them so much, perhaps he'll catch some of her enthusiasm. P doesn't like pineapple, but she loves apple slices that have been dipped in pineapple juice and then dried. Dried banana slices have gone over big not only with P, but with some of the other girls in her Brownie troop; and just about everyone likes our current form of fruit leather, made from an antioxidant-rich berry blend plus bananas.
P has decided to sign up for the next term of her aerial dance class. She's having fun, and I'm glad, partly because I find the parents at the aerial dance classes much more laid-back and friendly than those at the gymnastics classes at the same gym. I shared this observation with another mom at aerial dance, and she heartily agreed. I think the kids are also more motivated by fun, learning, beauty, and personal improvement than driven by competition with each other.
P is selling girl scout cookies. It's her first year in scouting, and this is her first experience with door-to-door sales. Her first day out was successful, and once she quit selling for the afternoon, she went bike riding and made a new friend on our block: the granddaughter of her biggest cookie customer, as it happened. Before setting out, P wrote down what different numbers of boxes of cookies (up to 12 boxes) would cost at $3.50 each, doing the math once so she wouldn't have to do it on the fly, and we role-played some scenarios she might encounter going door to door. We talked in between houses, refining her pitch and approach. She's also done some booth sales more recently at grocery stores, working with other girls from her troop.
P and I built a snow fort after a snowstorm that left 10 inches or so of powdery snow. It didn't pack as easily as I'd hoped, but P turns out to be better than I am at building snow walls, so it still worked out.
We've been playing lots of board games, especially games with a cooperative theme. I'm finding I have much more patience for complicated board games when they are cooperative rather than competitive. Getting to the end and winning or losing together just seems like a a better use of time than establishing a winner and losers, and the experience is more shared. Some we've played recently are Forbidden Island, Castle Panic, Pandemic, and Dixit. Forbidden Island is a simpler version of Pandemic (which we already owned) by the same game designer with a different theme (destruction and collective loss occur by flooding rather than the spread of disease). P went to a workshop run by a friend of mine, who uses the game as a way to spark creative writing with kids 8 and up. Dixit is not cooperative, but there's a lot of potential for creativity in the game. T doesn't always have the attention span to finish a game, but as he understands the game more, he gets more interested.

Making

We found a site where there are paper patterns you can print out and assemble into various toys. We built a paper trebuchet from there, and both kids enjoyed trying it out with different projectiles. P has a large collection of craft sticks and likes building things with them, so since the paper trebuchet wasn't very robust, perhaps we'll try with craft sticks next.

P has been folding origami, sometimes of her own design and sometimes from patterns. She asks for help a lot when working from instructions. Sometimes we fold a model side by side, with me following the instructions and P following me. I try to point out how the instructions show what I'm doing, so she can eventually follow them more easily herself; but I try to make sure I help when she's getting frustrated. Recently P and T have come to me a few times, when I was working in the kitchen, and said that they're having fun folding origami from instructions on their own. Origami books from the library have been great for this, so they can try new models.

Writing

P persisted and finished her Christmas thank-you notes, all but one handwritten (I scribed the other in email according to what P asked me to say). She is noticing out loud how much easier it is getting to spell the words she wants to use, and she is proud to show off her handwriting. She wants to hand-write party invitations, too (see last category below).
As noted above, P did a creative writing workshop with the board game Forbidden Island.

Watching

In the past few months we've bought two DVD sets of shows for the kids, and just recently they've been watching lots from both sets. One set is the complete Magic School Bus episodes. They've watched the majority of them now. T likes to watch the same one several times, especially certain episodes like the one about salmon migrating. Based on comments he makes about things later, I think he's picking up a lot of information. P definitely is.
The other set is Be The Creature, a Kratt Brothers series aimed at a slightly older audience than Wild Kratts. The episodes are longer, and they're all live-action, about real animals, rather than fantasy-cartoon plots related to the animals. P is more interested in them than T at this point, though sometimes T watches too. One day we were trying to think of an animal that wakes and sleeps when it wants to, without a particular nocturnal, diurnal, or crepuscular pattern. Lions came to mind -- I don't know whether they are awake much at night, but they sleep 20 hours most days, and given that they're successful only about 30% of the time on their hunts, waking hours may be opportunistic. P supplied the hours-of-sleep figure based on a Be The Creature episode about lions.
We got a great recommendation for a curated website, The Kid Should See This. We've enjoyed watching many short videos here, and sometimes following up with more detail on the subjects they touch on. Recently we've watched videos about life on the International Space Station (how to wash your hands in space was particularly mind-blowing for me!), elaborate marble runs made from just cardboard and cardstock, gut microbes, various dance styles, huge art installations, bird flocking behaviors, and many other topics. A couple of the videos came from TED-Ed, which has also been fun to explore.

Listening

I find that the kids, particularly P, quickly start echoing songs if I sing them as I clean up around the house and the kids play. Even if they're not fully tuned in, they're picking up the melodies. If they like the songs, I sing them while helping brush teeth, so they can pick up the words for themselves.
I've been noticing recently that P seems more attuned to my thoughts and feelings than she used to be. She is quicker to pick up on my meaning when I talk to her, and more readily apologizes when appropriate. I think she's passing a developmental milestone and getting better at seeing others' viewpoints, without their needing to be spelled out completely. She's also getting better at playing peacefully with T, at least when she wants to. Sometimes fatigue or hunger or the desire to do something else still sends the games off the rails; I try to step in with food or other aid before things go bad when I can see those times coming, or step in quickly afterward if I miss the early signs. We're all getting better at keeping the peace, bit by bit.
On Sirius Book Radio in the car recently, we heard a couple of excerpts from Danielle Steele's book, Echoes. The parts we heard were about the experiences of a young Christian woman (a Carmelite nun, actually) sent to a concentration camp in Poland during WWII, and later rescued and recruited into the French Resistance. P was very disappointed to turn off the radio when we reached our destination and needed to go inside. She really wanted to hear the end of that story. I assured her that we would be able to find a similar story, or that one, sometime soon. I wonder if she'd enjoy Marge Piercy's Gone to Soldiers, my favorite WWII historical fiction so far. It spans Jewish ghettoes, concentration camps, Jewish refugees in the United States (and how few of them were allowed in), WACS, the French Resistance, and other facets of experience in different places during the war.

Talking

Or not talking, as the case may be. We're in a phase now where one or both kids often have a hard time answering the question, "What would you like to eat?" Often, if I know they're likely to be hungry, I'll fix up a plate with one to four different things, at least some of which I'm pretty sure they'll enjoy, and just put it down where they are, without asking whether they want food or if so, what kind. This is usually met with hungry enthusiasm. One evening recently, I set down a plate with two toasted-cheese sandwiches, a bunch of baby carrots, and some dip. P said to T, who reached for the carrots first, "Don't eat all the carrots!" Discouraged as I get sometimes about their eating enough fruits or veggies or a wide enough variety of food, it really is happening that sometimes they prefer carrots to toasted cheese sandwiches. Or apples to sweetened dried fruits. Or smoked salmon with cream cheese on crackers to... whatever other food it was they were considering before I got out the salmon. When I stay on top of their hunger so they don't get carb-desperate, the proteins and plant-based foods do make it in. (Note to self: Breathe in, breathe out.)
T continues to ask questions, and sometimes to talk about his own ideas, concerning volcanoes, how they form, how and when they erupt, etc. P likes talking with him about what she knows, and I help out when I can contribute more information or clear up confusion.
In a recent conversation about the planets and their orbits, we talked about the geocentric and heliocentric models of the solar system, and how things like the apparent retrograde motion of some planets made it hard to justify the geocentric model, once people started considering the heliocentric model. (Retrograde was the only one of these big words that actually got used in the conversation.)
Both kids have been talking about their dreams a lot. They compare notes on efforts to turn bad dreams into good dreams, or at least get themselves to wake up from them. Both seem to have predominantly pleasant dreams, and they enjoy telling the stories of them.
I ran across the parlor game "Coffeepot" in the book Unbored. In this game, the word coffeepot stands in for a secret noun or verb, and questions are asked to discover what the word is. For example, one exchange tonight when only P knew the secret word (window) went, "What do you do when you're too cold at night?" "I make sure the coffeepots are closed and turn up the heat." It's fun to decide how obvious to make the hints, and to watch the reasoning process involved in the questioning and guessing. I floated the idea of playing "Coffeepot" via email -- it could be a fun asynchronous game to play with friends far away, and email threads could preserve the history of questions and answers, so total recall over several days wouldn't be important.

Visiting

We visited the zoo and had a chance to see the lion feeding-time demonstration -- two male lions being fed and going through the behaviors they are trained in to allow veterinarians and keepers to care for them without ever being on the same side of the fence or glass with them. P and T saw primary (food) and secondary (whistle) reinforcers in action and saw two very different lions, litter mates, in action. The first, who was highly motivated by food, was intensely focused as he went through his paces. The second, who was motivated more by his brother, was more relaxed and less in touch with the keeper. Both got their food (nine pounds each of raw meat plus whatever was mixed in with it), and we got to see two lions do some truly awe-inspiring stuff, like standing up against the barrier fence to give the keeper a look at their bellies and paws -- they stood seven or eight feet high! Later that evening I was reading a story about wildlife with T. On hearing about an animal who was scared of humans, T reminded me that the lions' keeper had told us the lions were scared of "two-headed people," meaning adults with children on their shoulders. I think it really made an impression on T that an animal so large and powerful could be scared of him.
T and I had a rare chance to take an unhurried trip together to the grocery store. We scrutinized the baked goods and found some delicious goodies made of ingredients we could live with. We looked at the fish counter, learning what mussels, oysters, and clams look like, and bought a whole trout to bring home so we could get a better look. We learned that trout have even spinier tongues than cats, which must be handy when you have no hands or claws to help hold the prey you've caught to eat. (P tried a taste later, when it was cooked, and said it wasn't bad; T really didn't want to taste it, saying he wanted to get the fish for me and Daddy to eat.) T considered spending some of his allowance on something from the toy aisle, but there was nothing he really loved, so for the first time in months, he was willing to save his money for something he'd really love, and he left the store without being upset about it and enjoyed the treats we had bought. I try hard to let him have experiences on both sides of the spending/saving choice, but ultimately the decision about whether to spend his allowance is up to him (though sometimes we leave without buying something because we're out of time), and mostly he chooses spending. Now he'll have a data point on the other side, of what it felt like to save his money for something he wants more, without being coerced to save.

Thinking, Asking Questions, Planning...

T has been asking lots of questions about space and astronomy. One evening he wanted to know how long it took a rocket to get from the launch pad into space. So we looked up how high space was considered to start (around 100 km above sea level was a good reference point). Then I said different rockets might take different amounts of time to get there, so T said he wanted to know about the most recent Mars rover mission. I looked up the launch sequence for the Mars Science Laboratory (MSL), and we found that it took around 3.5 minutes to cross the 100-km altitude. We talked about how heavy astronauts would feel if they rode on a rocket accelerating so rapidly. Then T wanted to watch several videos about the MSL. He also asked whether all planets had day and night, and I said they did, but some were very long (Uranus's day is the same length as its year because of the extreme tilt of its axis, so its days and nights are akin to those at Earth's poles; and Mercury's day is 176 Earth days long because of Mercury's slow rotation). Later that night I overheard more talk about planets and their orbits as UnschoolerDad was putting T to bed.
P and I watched an episode of Little House on the Prairie, one in which both Nellie and Laura/Mary had parties at their homes. We noticed that neither party had special activities planned, though there were special foods; the parties just took advantage of the greater number of people to play games that work best with several people involved. I suggested that, instead of trying to have a grand theme for our next party, we simply come up with a list of things P and T like to do that work better with more than three people (which is typically what we have available here), and invite over some people we'd like to do some of those things with. We made a list, both adding items. I added two of my favorite six-or-more party games, Pictionary and Taboo. P didn't know what they were, so I explained them. One thing led to another, and we ended up talking about what the word taboo means, some examples of taboos in our society, and the concept of sacredness as it relates to taboos (e.g., one might not say certain words to a priest, though one might use them frequently among friends). Now we have a list of activities, a list of friends, and a growing list of possible party foods; we're just waiting until we all get over our colds to plan a party.
One day, on a longish car ride, P and T suddenly had a slew of questions about reproduction and marriage. Can people marry in threes? (We talked about legal marriages, extralegal arrangements that the folks involved might consider similar to marriage, marriage in other countries.) T asked if the laws about marriage were different in different states, and we talked about the changes in same-sex marriage laws in recent years. They asked about how two men could have a baby (we touched on adoption, surrogacy, and sperm donation, finally summarizing that the creation of a baby requires an egg, a sperm, and a woman to go through pregnancy, but that these could come from two to three different people, and sometimes those who parent the child aren't any of them). We talked about the differences between adoption and fostering children, and why children might need foster homes. That led to questions about the age at which you go from being a child to an adult (we talked about differing laws for drinking, voting, serving in the military, getting a job, and generally being considered a legal adult, and also about terms like baby/child/teenager/adult vs. legal dichotomies like child/adult and the idea that one is always the child of one's parents, even when one is an adult).
We finally bought a globe this month, to add to our large world map hanging on the wall. This has led to interesting explorations and questions. Why is Boulder on the globe and not the larger world map? What does Antarctica look like? Which way does the Earth turn? What are those lines all about? What about the historic ships pictured in the oceans? When it's daytime here, where it is nighttime? T also likes the slight bumpiness on the globe in mountainous regions. One day, at a big library, we found a larger globe, mounted in a gimbal, so it could rotate along two axes, unlike our globe. He wanted to know what would happen if the Earth really spun on both those axes. That led to interesting talk about how the Earth isn't really rotating on a pin, but just spinning in space. (Having watched the space station videos helped with this idea -- T could imagine setting a globe just spinning in the air on the space station.) We also tried spinning the globe at a fairly uniform rate on each of its axes simultaneously, and saw that it sort of appeared to rotate along a third axis as a result, but it was hard to tell for sure. (I think you can just add rotations as vectors, but my physics is a little rusty there, and I'm not sure how it works when one of the rotations is along an axis that is itself rotating. This will bear more thought!)

Learning and Moving in Election Season

Once again we've been focused on our activities more than on writing about them. I think I detect a pattern! I'm very glad, this Election Night, to be done with the election and also past the hardest parts of moving to a new house in a new town (near enough our old one to keep our old friends). Now perhaps we can settle down into a new rhythm and explore a wider variety of interests. Here's a sampling of recent learning:

Reading

We read Little House in the Big Woods recently, as bedtime reading, and started on Little House on the Prairie. T listened carefully to the details of Pa making bullets, scrutinized the pictures, and asked me about it again a couple of nights later. P was excited to hear about square dancing and wanted to know if people still knew how to do it (yes) and if I knew how to do it (yes, a little). Perhaps we'll seek out some square dancing or contra dancing locally so she can try it. T asked what "pebbles" meant when we read about pebbles on the share of Lake Pepin. He knew about gravel from playgrounds, but didn't remember hearing small rocks called pebbles before. We read about cheese making, maple sugaring, and much more. As we started running into parts that are derogatory toward Indians, I noticed several local homeschooling moms chatting online about what other books they've used to give a more accurate or balanced view of Native Americans in that time period. We have one well-liked book from that discussion on hold at the library now; more on that when/if we read it!
P checked out several graphic novels at the great library that is a short walk from our new house. She's especially enjoying Akiko (the children's librarian said a lot of girls especially like this series), and it's wonderful to hear her read aloud from it. She's very fluent and gets a lot of appropriate expression into her reading voice.
T continues his frequent readings with UnschoolerDad of The Sneetches and Other Stories. He likes to read some of the words on each page (mostly from memory, but there is some actual decoding starting to happen), and with almost every reading he wants to read more of the words. He's asking just the right kinds of questions for starting to decode; for example, he asked UD why there were little sixes everywhere -- that was how he saw lowercase a, as he's still learning some of the lowercase letters.
