Beginning with an online interactive exploration of Karijini Gorge in Australia and Oak Creek Canyon in Sedona, AZ, learners gather geologic evidence regarding the formation of the red rocks found in each. They then apply that information to support... (View More)

Using an online interactive platform, learners will explore our solar system from the perspective of the Sun. They will observe the motion of different worlds to determine their location in the solar system. Then they will launch probes to search... (View More)

Participants experiment with ultraviolet light sensitive plastic beads, which are generally white but turn colors when exposed to UV light. They are informed about the nature and risks of UV light and are asked to explore what types of materials... (View More)

Students will test various materials to determine if any can shield their "magnetometer" (compass) from an external magnetic field using their own experimental design. If no suitable material is available, they will devise another method to protect... (View More)

Students simulate the process of remote sensing by using common materials to represent Earth’s different ground coverings and a light meter to represent satellite instruments. The concept of albedo and its importance in Earth’s radiation budget... (View More)

The basic chemistry of water, along with a brief glimpse into water's origin on Earth, are discussed in this two page article. The article can be used as a "reading to be informed" activity in a stand-alone fashion or can be incorporated into a... (View More)
