Its been a while since we've done this at home, it has always been a hit with the kids. Watching caterpillars grown, into butterflies. Another one that was fun to do was the prey mantis egg/pod, we could actually here them gnawing their way out of the pod. We've tried tadpoles, but ours do a mass suicide :(
Interestingly, the day I surprised the girls with the catepillars, Trinity brought home a library book on butterflies. They thought they where just having fun.
