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 math-science integrated unit about spectrographs. Learners will find and calculate the angle that light is transmitted through a holographic diffraction grating using trigonometry. After finding this angle, the students will build their... (View More)

Audience: High school

This interactive, web-based activity allows children to see the universe in many different wavelengths of light - light our eyes can and cannot see. To use the viewer, first select a celestial object (planet, galaxy, etc.), then select an... (View More)
