Most children are unaware of the process of molting, the periodic shedding and replacement of part or all of a coat or an outer covering of an animal, but it is an animal characteristic they are sure to be interested in and should have the opportunity to observe. In this article, the author shares how she and her students observed various creatures molt inside their classroom. She and her class observed how pill bugs, crayfish, an anole, and an alligator lizard molt their skins. As a culmination to the exploration of molting, students participated in a role-play where they pretended to be molting snakes. The children took turns wearing a tubular stretchy costume, resembling a snake. In the role play, the costumed-student wiggled away, trying to peel his or her body from the outfit as the rest of the class counted aloud how many seconds it took them to finish molting. They understood that when they were pretend snakes, they molted much faster than real snakes did. Through these hands-on adventures, students observed how different animals grow and began to discover what it means to "be a scientist." (Contains 1 figure and 7 resources.)
