Shadow Play

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky. Learners will trace, measure and compare their shadows over time, rotate around a lamp to mimic the Earth's daily orbit, and use a flashlight to simulate sunrise and sunset over an action figure. These activities can be combined as a comprehensive unit or used individually. If used individually, learning time will vary. This lesson guide also includes information about Sunwatchers, special members of the Pueblo tribe.
