Activity 14: Make a Homemade Sun Clock

In this lesson, discover how to make a homemade sun clock to learn about Earth's rotation. You'll create a clock using simple materials like a paper plate, a straw, and some clay. By setting up your clock outside and observing how the shadow moves throughout the day, you’ll see how the Earth's rotation causes the sun to appear to move across the sky, just like the shadow on your clock.
