The other day before nap, Owen and I were reading this book:
It's a book about a little girl who gets really angry and what she does to calm down. On one page, it says she's like a volcano, ready to explode. Owen asked what a volcano was so I proceeded to tell him a little about it and told him we'd learn more after nap. When he got up and the little miss was still sleeping, we watched a couple you tube videos on real volcanoes and then did the classic food coloring, baking soda, and vinegar trick. He wanted to do it over and over. So fun to watch him learn!
