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, students learn how fiber optics work by observing a model using gelatin and observing how the internal reflection of light allows light to bend within the system. The resource is part of the teacher's guide accompanying the... (View More)

In this demonstration, students learn about the physical process of liquification and how it causes the ground to become unstable during an earthquake. Required materials include a plastic tub, sand, water, a brick and a rubber mallet. The resource... (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)

Students become familiar with strike-slip faults, normal faults, reverse faults and visualize these geological structures using cardboard or a plank of wood, a stack of books, protractor, and a spring scale. The resource is part of the teacher's... (View More)

In this demonstration, students see how the different wavelengths of the visible light spectrum combine to make white light. Student cut circles out of poster board, color sections red, orange, yellow, blue, green and violet, suspend it in the air... (View More)

In this demonstration, liquids of different density are mixed to demonstrate how the layers of the Earth were formed as the denser materials sank to the inner portion of the Earth with the less dense materials, such as our crust, remaining on top. A... (View More)
