Sun, Light and Shadows


Levels: Grades 2-4

Description:  Students learn about the sun, light and shadows as they experiment with different light sources and objects in this science activity for the younger grades. Moving a light source closer to an object can make its shadow grow larger, while moving the light source away can have the opposite effect. Experiment and see what happens to the shadows of different objects when you tilt the light source or change its brightness. What happens to the shadow if the light source is dim? Head outside and see how sunlight creates shadows with various objects such as trees, houses and cars. Learn how the sun's position in the sky effects the size of shadows. Even the moon can create shadows when it reflects light from the sun.
