The document discusses the 5-E model of instruction for teaching science. The 5-E model includes 5 phases - Engage, Explore, Explain, Elaborate, and Evaluate. The Engage phase introduces a topic to spark curiosity. The Explore phase allows students to experiment. The Explain phase guides students to understand concepts. The Elaborate phase has students apply concepts to new situations. The Evaluate phase assesses student learning throughout the process. The 5-E model is based on an inquiry approach and is designed to help students develop scientific understanding.
