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

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

In this activity, learners use their feet to estimate distances. Learners calculate the distance of one step in centimeters by measuring 10 steps at a time to reduce measurement error.

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

In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

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

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this activity, learners use their hands as tools for indirect measurement.

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

In this geometry activity, learners explore networks painted on playgrounds, such as a four square court, and draw their own.
