In this 10-minute demonstration or 30-minute activity, children ages 8-13 investigate the source of the Moon's light. They consider a ball, wrapped in aluminum foil, and experiment with a flashlight to make it appear bright. The children compare the foil-wrapped ball to a Moon globe and discover that the Moon reflects very little of the light that falls on it, but it still appears bright. The children may construct their own globe of the Moon to take home with them by gluing a map template onto a tennis ball. This activity is most effective when conducted in a dark area, such as outdoors at night or in a darkened room.
