Day & Night

Explore sunlight, shadows, and Moon phases as rabbits forage and shelter. Change the date and location to see how the woodland responds.

Watch the woodland and its rabbits move through sunlight, twilight, and darkness.

Earth turns around once each day. Our part of Earth has daytime when it faces the Sun, and nighttime when it faces away.
Here we watch from the ground, so the Sun seems to move across the sky. Shadows stretch when it is low and become shorter when it is high.
The Moon reflects sunlight. As it travels around Earth, we see different amounts of its bright half. These shapes are its phases. The Moon can be up during the day too!
Rabbits take longer feeding trips around sunrise and sunset. They rest more during the bright daytime, near trees or inside burrows.

Try this: Look for the daytime Moon in the starting scene. Change the date to compare day lengths and Moon shapes.
