Students participate in hands-on inquiry-based centers and guided activities to increase knowledge of shadows and light. Students explore and manipulate light, using a light source to simulate the sun at various times of day and observe shadows, create and measure shadows, and test how various types of media block light. Students explore the shadows created by the sun and experiment with a “solar oven” to demonstrate how overexposure to the sun can be harmful. Students then create shadows outside, given various materials with different sizes and transparencies. Finally, students apply their knowledge when given the engineering design challenge of creating a sunshade that protects a model section of their playground.
