Secretly add a picture of a moth with the butterflies. Students decide which insect does not belong in the category and why. Continue with other types of insects or spiders. Observe the growth of caterpillars. Make a large chart to record the daily changes.
Students use words and drawings to record the changes.
One yard of netting. First, staple or hot glue the netting material to one top piece and one bottom piece of cardboard. Next, glue another circle of cardboard over these to hide where you attached the netting. The door is simply where you overlap the extra material. After we released the butterflies, we left our cage hanging to hold other insects and even a lizard.
