In this mini-lesson, K-5 students consider what would happen if their body didn't have bones. In the activity, Skeleton Hand, students combine science with art: they trace their hands, then add see-through bones to their picture, making their own skeleton hand. The activity includes an extension for older students to compare their hand bones to the bones of a mystery animal.
