Yay--my TNT teaching is all done! Last week we covered landforms, but this week's topic (for the same 1st and 2nd graders) was the 3 different kinds of rocks. I scoured the internet and combined a few different ideas so that we had an edible "model" for each type of rock, models that did not need to be heated or cooled there on the spot, and also that did not include peanut butter!
For sedimentary rock, I made rice krispie treats, mixing in M&Ms for some larger pieces of "sediment", like a conglomerate rock. (And of course I gave each child a little piece.)
For metamorphic rock, I gave each child 2 Starburst of different colors, and by holding them in their hands (heat) and squeezing them together (pressure), they made "marbleized" starburst rocks (which they could then eat). It was fun, and hopefully memorable.
After finishing at TNT, I came back home and taught at Rivendell all afternoon, first chemistry, then memory work. The most wonderful thing about getting my TNT teaching out of the way so early in the school year is that the chemistry chapters and labs this week and last were ridiculously easy and introductory, requiring almost no thought and preparation from me. I keep telling the boys, it will get harder, but for right now, it is such a review of Integrated Physics and Chemistry 2 years ago. And that has been so nice for me! But now that geology is over for me (the kids still have 2 more weeks with a different teacher), I can devote more time to chemistry. And everything else in my life, LOL.
