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

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.

In this physics activity, learners conduct two experiments to explore free-falling.

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