In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

Like water drops in falling rain, a CD separates white light into all the colors that make it up.

In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

In this activity, learners make a photographic image—without a camera!

In this activity, learners create a "mini sky" in a glass of water in a dark room.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.
