Case Study – Investigation of Animal Behavior

animal-behavior-thumbnailThis case study builds upon a traditional AP Biology lab on animal behavior where students design an experiment to text taxis is pillbugs.   Instead of a stand-alone lab, this case study investigates historic experiments on animals that ask questions about whether behavior is learned or innate.  The goal is for students to develop a basic understanding about how animal models are used to study behavior and how behavior can be explained from an evolutionary perspective.  Students even revisit the chi square equation and the null hypothesis to determine if data show a true preference toward a stimulus.

Students learn about feedback mechanisms, and positive and negative taxis, finally culminating in an experiment they design to investigate whether an animal model exhibits taxis toward a stimuli. Students can use pillbugs they collect outside or use animals raised in the classroom, like mealworms or dubia roaches.
