This is the first year I've ordered caterpillars so the kids could watch their life cycle. It was very interesting, but the caterpillars/butterflies were very sneaky! Eight of the 10 emerged from the chrysalis over a weekend. The 9th one emerged while we were immersed in our math lesson. I was determined the kids would get to witness one emerging! I put the habitat at the very front of the room so we could watch closely. I turned off the light to show a 4-minute video on life cycles and when the light went back on, the 10th butterfly had emerged! We missed them all! For 3 days we watched them flutter around their habitat, waiting for a sunny, calm day to set them free. The kids decided to name the butterflies as they flew from their habitat. They were all named Jr. What a fun time the kids had watching them fly away!
