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.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity, learners simulate a wolf and its habitat and observe what happens when the limiting factors change over time.

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.
