Students examine fossilized owl pellets to determine how a species environmental preferences allow us to reconstruct probable past environments. Differences in anatomy are used to identify species in this instructional activity.

Students examine how the method of classification is used. In this sorting lesson students take a pre-test, classify organisms and complete a crossword puzzle.
