This video-enhanced lesson will challenge students to design and conduct scientifically valid experiments to evaluate hypotheses regarding an animal’s expected behavior in response to changes in its environment. (Grades 9-12)

This video-enhanced lesson uses segments from the NATURE program "Ravens" to explore what scientists can determine about animal intelligence. (Grades 9-12)

Segments from NATURE's "Ravens" demonstrate indicators of animal intelligence, including communication, counting, memory, and basic problem solving.
