This is a lesson about emission spectra. Learners will look at various light sources (including glow sticks and christmas lights) and make conjectures about their composition. The activity is part of Project Spectra, a science and engineering... (View More)

This lesson provides a way for students to determine the relationship between the distance from a light source and its brightness. Once students discover the relationship, they can begin to understand how astronomers use this knowledge to determine... (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)

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)

This is a lesson about the electromagnetic spectrum. Learners begin by arranging a set of picture cards; in the discussion afterwards, this activity is related to the electromagnetic spectrum as an arrangement of energy waves. Next, using a... (View More)

In this lesson, students create a timeline of world events from 1905 until 2006. Students locate key dates from the Cosmic Times poster series and determine world events that fit into the three story strands of Cosmic Times, as well as, the... (View More)

This is an educators guide to accompany the Journey to the Stars planetarium show. The materials include a section, titled Teaching With the Show, containing guiding questions to encourage class discussions about the life cycle of stars.

This is a lesson about the electromagnetic spectrum. Learners will read two pages of information about the electromagnetic spectrum and answer questions in an accompanying worksheet. This activity is from the Stanford Solar Center's All About the... (View More)

In this lesson, students will be introduced to how the Doppler effect changes our perception of wavelengths of sound (pitch) and light (color). Students will model how astronomers use the line spectra of stars to identify elements in the stars and... (View More)

In this hands-on activity, learners begin by estimating the size of each planet in our Solar System and Pluto and making each out of playdough or a similar material. Then, learners follow specific instructions to divide a mass of playdough into the... (View More)
