Lesson: How Do Plants Make Their Own Food? (60 min) Objective: Students explain how plants convert sunlight, water, and CO2 into glucose and oxygen. Warm-up (10): Pose the question 'Where does a tree's mass come from?' and collect predictions. Explore (20): Elodea bubble demo - students observe oxygen production under light vs. dark. Explain (15): Short video + guided diagram of the photosynthesis equation. Elaborate (10): Students sketch the process in their own words. Close (5): Exit ticket - one thing that surprised you.
