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 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... (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)

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 visual spectra. 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... (View More)

This is a lesson about how to plan a mission to explore another world in the Solar System. Learners will discuss the path of a spacecraft traveling between planets, examining the journey from the Earth to Mars as an example. In Activity 1, students... (View More)

This is a lesson about the value of exploring our solar system and others in the Universe. Learners will investigate, compare, and describe patterns in Solar System data. They will then hypothesize about the formation of the Solar System based on... (View More)

Audience: High school

This is a lesson about how spacecraft use gravity assists to get where they are going. Learners will explore how engineers minimize the use of fuel by utilizing gravity. In Activity 1, students explore the physical conservation laws by observing the... (View More)

Audience: High school

This is a lesson about the path of one xenon ion through an ion propulsion engine. Learners will focus on what a single xenon ion sees and does as it goes through the reactions and processes that provide the ion jet propulsion engine's thrust. They... (View More)
