This is an activity about color. Participants will use scientific practices to investigate answers to questions involving the color of the sky, sunsets, the Sun, and oceans. This activity requires use of a clear acrylic or glass container to hold... (View More)

Audience: Informal education

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 an activity about the Doppler effect. Learners begin by simulating the noise made by a passing siren. After learning that the change in pitch results from movement, they investigate the definition of frequency, calculate change in frequency,... (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)

This is an activity about the electromagnetic spectrum and how light is split into its component frequencies or colors. Using a diffraction grating, learners will observe four different light sources and sketch their spectra. This activity requires... (View More)

Keywords: Doppler effect
Audience: Elementary school, Middle school, High school

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)

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)

Audience: High school, Higher education
Materials Cost: $1 - $5

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 activity introduces learners to the visible portion of electromagnetic spectrum. A visible spectrum is projected in the classroom using a diffraction grating and learners reproduce it using colored pencils. Filters are also used to block... (View More)

In this demonstration, a flashlight, mirror, water and a plastic shoebox are used to refract light into its component wavelengths, seen as colors of the visible spectrum. Students create a drawing of the sequence of colors in the rainbow. The... (View More)
