The document provides an overview of the 5E instructional model and how it can be used to structure lesson plans. The 5E model includes five phases - Engage, Explore, Explain, Elaborate, and Evaluate. Each phase serves a distinct purpose in helping students build new knowledge and understanding. The Engage phase introduces a lesson to spark student curiosity. Explore allows students to actively investigate concepts. Explain supports students in explaining what they have learned. Elaborate has students further apply their knowledge. Finally, Evaluate assesses student understanding. The document also provides examples of how each phase could be implemented in a sample lesson on camouflage.
