Vision and Light

Students investigate why there is a decline in the number of Tokay geckos living in one area of a rainforest in the Philippines. They plan and conduct investigations and analyze data related to animal senses to figure out cause-and-effect relationships between environmental changes, the parts of an animal’s vision system, and the animal’s ability to see well. They make models and write explanations to share what they learn about how animals’ body structures perform functions related to senses and survival.

Chapter 1: How does a Tokay gecko get information about its environment? 

Chapter 2: How does light allow a Tokay gecko to see its prey? 

Chapter 3: How does a Tokay gecko know that it is looking at its prey? 

Chapter 4: How could more light at night make it hard for a Tokay gecko to see its prey?
