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 laboratory activity, learners explore the difference between heat and temperature, and explore the rate of heat transfer from one substance to another as it depends on the density of the substances being investigated. The activity can be... (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)

This is an activity about Earth's magnetosphere. Learners will use a magnet, simulating Earth's protective magnetosphere, and observe what occurs when iron filings, simulating the solar wind, blow past and encounter the magnet's field. This is the... (View More)

In this demonstration, an apple is used to help students visualize the relative amounts of land and water resources on the planet, and highlights the vulnerability of these resources we share. The apple is sectioned proportionately according to... (View More)

This demonstration shows that an increase in temperature will speed up the water cycle. One outcome will be an increase in rainfall. A second outcome will be the increase in total evaporation of water and subsequent drought. Materials required... (View More)
