In this lesson, students will investigate the Doppler Effect and discover how the same principle can be used to identify a possible tornado in storm clouds and investigate the rotation of distant galaxies. Students should be familiar with the... (View More) electromagnetic spectrum and the concept of Doppler Shift (links to background information are provided). Materials required for every group of 2-4 students include: a Slinky toy, safety glasses, meter stick, and colored pencils. This lesson is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1965 Cosmic Times Poster. (View Less)

In this activity, students will learn how technology can help scientists solve a problem. One of the challenges scientists face with any spacecraft is attitude control. Students will be introduced to the problem of attitude control in space through... (View More) an experiment using angular momentum, and experience two different ways scientists address this problem. Students begin by discussing the technology(ies) that powers satellites and enable(s) them to move through space. Students then engage in an angular momentum experiment. Estimated cost of this activity does not include the cost of the bicycle wheel for the angular momentum experiment. This activity is one of several in the Swift: Eyes through Time collection available on the Teachers' Domain website. (View Less)

In this activity, students demonstrate the relationship between wave frequency and energy in the electromagnetic spectrum by shaking a rope to identify the relationships. This activity is part of Unit 2 in the Space Based Astronomy guide that... (View More) contains background information, worksheets, assessments, extensions, and standards. (View Less)

In this activity, students study the range of colors in a visible light spectrum created from either a glass prism or holographic diffraction grating. This activity is in unit 2 of the "Space-Based Astronomy" guide that contains background...
