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

In this activity, learners walk the sides and interior angles of various polygons drawn on the playground. As they do so, learners practice rotating clockwise 180° and 360°.

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

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

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

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!

You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

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 math activity, learners observe and sketch cracking patterns in pavement.

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