This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

In this activity, learners take core samples of candy bars with a straw and carefully observe & excavate their sample, modeled after what the NASA Perseverance rover will do on Mars.

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.
