What have we learned? (Sunlight takes 8 minutes to reach the Earth.) Shadows form when light is blocked out. Night is when no sunlight reaches us. We can tell the time by shadows. In winter the Sun is low in the sky. The moon reflects light to the Earth. Its shape changes because of shadows. Eclipses happen when light is blocked out. - all shadows!
