When Do Lunar Eclipses Happen?

This When Do Lunar Eclipses Happen? activity also includes:

Who needs the daylight to simulate a lunar eclipse? Astronomers model the positions of the Sun, Earth, and Moon to explain the necessary conditions for a lunar eclipse. Investigators cut and label a paper plate to represent the Earth and Moon and use a ball to model the Sun. By manipulating the paper plate and ball, explorers recognize the correct moon phase during an eclipse and why eclipses occur at certain times of the year.
