In this activity, pairs of learners will create two make-believe dig sites by burying chicken bones in plaster of Paris--a powder that hardens when wet. Then, learners try to excavate (dig out) their partner's "fossils." Learners will discover that excavating fossils requires skill, patience, and the right tools. Note: this activity requires adult supervision as working with plaster of Paris can be dangerous if not done properly.
