This is an activity exploring the concept that distance affects how we perceive an object's size, specifically pertaining to the size of the Sun and the Moon as seen from Earth. Learners will complete a hands on activity where two balls of differing sizes stand in for the Sun and the Moon. By moving the balls away from each other, students will determine how far the larger ball needs to be in order to make the two seem similar in size. They will also use the balls to demonstrate a solar eclipse. Lastly, learners will complete a worksheet explaining their findings. This is Activity 12 of a larger resource entitled Eye on the Sky.
