Students analyze and interpret the accompanying large-format images of Mars taken by NASA’s Mars Thermal Emission Imaging System (THEMIS) camera. The analysis involves identifying geologic features, calibrating the size of those features, and... (View More)

Dieter Hartmann, a high-energy physicist, presents a story-based lesson on the science of Gamma-Ray astronomy. The lesson focuses on gamma-ray bursts; examining their sources, types, and links to the origin and evolution of the Universe. The... (View More)

This is a lesson that applys occultations to Saturn's Moon Enceladus. Learners will establish whether Saturn’s small moon, Enceladus, has an atmosphere, whether that atmosphere is over the entire planet, and what creates Saturn’s E-ring. The... (View More)

This is a lesson about using the light from the star during an occultation event to identify the atmosphere of a planet. Learners will add and subtract light curves (presented as a series of geometrical shapes) to understand how this could occur.... (View More)

This is a lesson about detecting atmospheres of planets. Learners will explore stellar occultation events (by interpreting light curves) to determine if an imaginary dwarf planet "Snorkzat" has an atmosphere. The activity is part of Project Spectra,... (View More)

This is an activity about detecting elements by using light. Learners will develop and apply methods to identify and interpret patterns to the identification of fingerprints. They look at fingerprints of their classmates, snowflakes, and finally... (View More)

Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction... (View More)

Using a set of activities, recommendations, and diagrams, participants will construct a fully functional Space Weather Action Center (SWAC) for use in a classroom. Students will access, analyze, and record NASA satellite and observatory data to... (View More)
