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)

In this activity students investigate cloud opacity, including transparent, translucent, and opaque cloud characteristics. The activity is a companion resource to an episode of the PBS series, SciGirls. The episode, titled "SkyGirls," featured NASA... (View More)

Twice each day, once during daytime and once at sunset, students observe sky color, visibility, and sky conditions over a one week period. Each observation is recorded on a sky report form (included) for follow-up discussions and comparisons. This... (View More)

Through the use of prisms and glue sticks, this activity introduces students to a fundamental property of light: white light is made up of colors representing different wavelengths. Students use the results of the activity to explain the variation... (View More)

Working in groups, students use contact paper to make samplers to collect local data on aerosols - the small particles found in the atmosphere. Students then analyze, interpret and make predictions based on their data. Both the instructions for... (View More)
