The lesson will teach students about typical signal and response behavior between animal parents and their offspring. Students will observe patterns of behavior (signals and responses) that are used to help offspring survive. They will explore typical offspring signal behaviors (crying, chirping, vocalizing) and parent responses(feeding, comforting, protecting). Students will jot down their observations after watching videos of birds, lions, and orangutans interacting with their offspring. Students will look at several different examples of parent and offspring behavior and answer questions to show their understanding. Then, they will complete a sorting activity to demonstrate their understanding of parent and offspring survival behaviors.
