Learners will build an open spectrograph to calculate the angle the light is transmitted through a holographic diffraction grating. After finding the desired angles, the students will design their own spectrograph using the information learned. The... (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)

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 science news story highlights Hubble's infrared image of the Horsehead Nebula. Students will discover why astronomers are interested in this nebula and how they study the nebula using infrared light. Star Witness News is a series of articles,... (View More)
