Students identify general abilities that indicate animal cognitive intelligence. In this biology lesson, students create an intelligence testing challenge for ravens. They compare its ability to that of a crow.

Students explore the functions of the brain. They create their own "live" model comparing a phrenology chart to our modern understanding of brain function and anatomy. Students compare and contrast brain models.

Students review information on a website which shows different types of spiders. They sort images of spiders from other insects. They create their own spider out of materials and share them with their classmates.
