THIS LESSON WAS REVISED ON JULY 1, 2019. Here is a link to the previous version.
In this lesson, students come to understand that the setting Sun isn’t moving, the Earth is spinning. In the activity, Spinning Earth, students use their bodies as a kinesthetic model of the Earth to understand how the speed of the Earth’s spin affects the length of a day.
