This activity invites students to simulate and observe the different effects on sea level from melting sea-ice.

Hands-on demonstration of the El Niño Effect, trade winds, and upwelling provided by NASA's Jet Propulsion Lab.

Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes.

In this activity, students investigate three different soil samples with varying moisture content. They use a soil moisture probe to determine the percentage (by volume) of water in each of the soil samples.
