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)

In this activity, students experience a demonstration of light scattering that explains the blue colors in the Intersetllar Medium (ISM) nebulae, and the reddening of stars viewed through the ISM. It also explains the blue appearance of the sky on... (View More)

Traditionally, spectral images are two dimensional, and related to text. This kinesthetic activity has groups of students position themselves along a printed spectrum to make spectral patterns and model various elements. Includes photos, teachers... (View More)

This is a lesson about discovering distant planets using an Earth-based observing technique called stellar occultation. Learners will explore how a stellar occultation occurs, how planetary atmospheres can be discovered, and how planetary diameters... (View More)

In this activity, students use a piano keyboard to model spectral lines as musical chords. It is designed to aid student understanding of spectral analysis, what the patterns mean, how elements are involved, and how this relates to stars.... (View More)

This exploration engages students in an investigation that leads them to the conclusion that regions of the electromagnetic spectrum vary according to energy per photon, and connects with the video where Dr. Ilana Harrus explains observing a... (View More)
