In this activity, learners explore why they can see colors in bubbles and why they change.

In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

This is an activity to do when there is a solar eclipse!

In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
