Jman watched his first caterpillar to butterfly transformation the past 2 weeks. If you have never actually watched this process I highly suggest it! I did it for the first time as a teacher. Its as exciting to watch as an adult as a kiddo.
Jman called them bugs and flies. Our caterpillars arrived in the mail and he was fascinated. We had to talk about not shaking them or opening it. He watched them eat and get fatter. Every morning he ran over to see his "bugs". We watched as they crawled to the top and began to form their chrysalis. He had a real hard time just watching and not touching once they did this. Well of course he did, he's 2.
