I’ll write up a full review of our week in the next day or two, but here are some pictures to show what we’ve been up to – including both deliberate and accidental science experiments, and some of our art work!
First of all, we had a leak. No, not the (numerous) ones from the roof (don’t get me started), but one from a bottle of baby shampoo that didn’t get unpacked after our holiday trip. It leaked INTO our bag of plastic pattern blocks. Ew! Anyway, Beara, Big D and I started an assembly line to get them all washed, dried off and put away, and this was what happened in our rinse bucket! This experience might make a reappearance for bathtime someday…
Next up, we have some of the art I’ve been talking about for the last week or so. The hearts are mostly Beara’s creations (with uber-carefully applied glitter glue), but the cut out one is Big D’s. (These are *serious* labors of love; they have been working on them every day for over a week, and Beara was seriously worried that folks would mind getting them so long after Valentine’s Day, but I assured her that love is always on time. 🙂 In the lower right you can see Buddy’s spider he made for me, with eight legs and everything, and, at the top, Big D’s first experiment with outlining letters, in this case copied off her brother’s Wolverine punching bag.
Last but definately not least, our Experiment. (Yes, I’m a science geek, and I feel like capitalizing it. Deal.) I stole this
experiment Experiment whole hog from Earth Explained by Barbara Taylor. (The book will be read one incredibly pithy and well-illustrated page at a time starting next week.)
We have been studying the creation (areligious, tyvm) of Earth, from the Big Bang on up to the formation of Earth’s crust and the condensation of water vapor out of the atmosphere and into oceans. This Experiment was simple, sweet, and -best of all – cheap and non-messy!
Basically, take stick on stars and put them close together on an uninflated balloon. I *strongly* stuggest you stretch it out, or even blow it up and empty it again *first*. (Oi.) Then you blow the balloon up, showing how the stars, representative of galaxies, spread farther apart from one another, like they are now as a result of the Big Bang. Note that the stars themselves don’t get any bigger: the galaxies and their contents, even clumps of galaxies, all formed under the influence of gravity, and gravity still holds them together even with the universe spreading out around them. (This is why Sharpie dots won’t work – they’ll stretch with the balloon. Go with stickers.)
If you want to take it the extra mile, you can show how stars placed near the neck of the balloon haven’t spread so far from each other, modelling the theory that different parts of the universe are expanding at different rates. Yes, this model ignores that there are a multitude of galaxies *inside* the space represented by the rubber of the balloon, but hey – what do you want for 25 cents worth of materials? 😉
