In this problem-based learning (PBL) activity, students take on the role of a student research scientist and explore the role of solar energy in determining climate. Students conduct experiments to observe how a change in water phase affects surface... (View More)

In this problem-based learning (PBL) scenario, students prepare a presentation for investors showing how their fishing company has a significant advantage because it locates upwelling zones and fishing areas using TRMM (Tropical Rainfall Measuring... (View More)

In this scenario-based, problem-based learning (PBL) activity, students investigate cloud formation, cloud classification, and the role of clouds in heating and cooling the Earth; how to interpret TRMM (Tropical Rainfall Measuring Mission) images... (View More)

In this activity, students create a reservoir model using hoses, a bucket, a flat pan, and water, to understand the inputs and outputs of a local watershed or reservoir. The resource is supported by teacher background information, assessment... (View More)

Students experiment with a model system made from a wooden block, sandpaper, a thumbtack, and a rubber band to understand earthquakes. In this system, the rubber band stores energy until it accumulates enough energy to overcome friction and move the... (View More)

This demonstration is designed to show how the inputs and outputs of energy or mass in a system balance. Students create a reservoir model using a hose, a bucket, a tub with a drain and overflow triangle, a ruler, and water, to understand the inputs... (View More)

In this activity, students investigate the interacting parts of the Earth system by observing changes in evaporation rate in four small aquariums with different initial conditions. The demonstration requires 4 small aquariums, soil, plants, water,... (View More)

In this demonstration, a flashlight, mirror, water and a plastic shoebox are used to refract light into its component wavelengths, seen as colors of the visible spectrum. Students create a drawing of the sequence of colors in the rainbow. The... (View More)
