In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.

In this weather-related activity, learners make a portable cloud in a bottle.

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.
