This investigation introduces students to the phenomena of urban heat islands, areas of higher then normal temperatures associated with populated areas. Using Atlanta, Ga., as the study site, students begin by analyzing the population growth and... (View More)

Worldwide patterns and sources of aerosols are analyzed and evaluated for potential hazards to aircraft safety. Using aerosol index maps created from data gathered by the TOMS instrument, student groups will analyze and compare aerosol data from... (View More)

This is a activity about how reaction wheels affect spacecraft orientation (attitude). Learners will observe Newton's Third Law (action-reaction) in the changes caused by a reaction wheel acting upon a spacecraft suspended from a support wire and in... (View More)

This is a lesson about the role of robots in space exploration. Learners will examine their prior notions of robots and then consider the characteristics and capabilities of a robot, like the Cassini-Huygens spacecraft, that would be sent into space... (View More)

In this lesson, learners will use History of Discovery cards and interpretive skits to examine how scientists throughout history have explored Saturn. The lesson enables students to discern the multicultural nature of scientific inquiry and to see... (View More)

This is a lesson about the connection between meteorites and asteroids, focusing on remote-sensing techniques using light. Learners will make and record observations and measurements; analyze data and draw analogies; compare samples; measure and... (View More)

Students will create a three-dimensional model from a two-dimensional topographic map. They will use the model to trace the path that a water droplet takes across the watershed and into the watercourse, and will describe the relationship between the... (View More)
