Solar Eclipse
Push a skewer into the Styrofoam ball to model the moon. Take a partner outside on a sunny day and bring the “moon” and the rubber ball “Earth.”
Hold the "Earth" near the ground. Have your partner walk about 10 feet away from you, toward the sun. She should hold the "moon" so it blocks the sun from shining on the "Earth." As she looks at the "Earth," a small dark shadow (umbra) surrounded by a lighter, fuzzy shadow (penumbra) should be visible to illustrate the solar eclipse.
Ask your partner to move the "moon" slowly so its shadow moves across the "Earth." As the moon moves farther away, the umbra will disappear. Observers who see only the penumbra see a partial solar eclipse. Change places with your partner and repeat the demonstration.
Warning
Never look directly at the sun during an actual solar eclipse to prevent permanent eye damage. Use an approved viewing device.
