In this lesson, students explore how eclipses happen and why Einstein needed a total eclipse to image stars near the Sun in order to demonstrate how the Sun's mass bends the light from a far away star. Using a foam ball and a lamp, learners create a solar eclipse, a lunar eclipse, and learn more about why the moon appears differently from one night to the next. The activity needs to be done in a very dark room and requires a very bright light (e.g., a lamp without a shade) and a very dim light (e.g., like one found on a keychain). This activity is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1919 Cosmic Times Poster.
