This article describes an indoor, game-type demonstration, incorporating physics (EM wave modulation), math (binary codes), space technology, and music to show how spacecraft put information into the radio signals they send back to Earth. The... (View More)

Audience: Middle school

This is an activity about wavelength and frequency. Using a 30 to 50 foot rope and two volunteers, learners will observe as one end of the rope is shaken and wavelength patterns are created. They will estimate the wavelength, the distance between... (View More)

In this activity, a Whiffle® ball containing a battery-operated buzzer is twirled in a circle to demonstrate the Doppler effect.  The demonstration is an illustration of how stellar spectra can be used to measure a star’s motion relative to... (View More)

This is a student reading about the different types of spectra: continuous, absorption, and emission. Learners will read about the differences between each and see graphical representations of each. This activity is from the Stanford Solar Center's... (View More)

Using a paper and tape device, students experience how atoms and molecules of gas in Earth’s atmosphere absorb electromagnetic energy through resonance. This activity is part of Unit 2 in the Space Based Astronomy guide that contains background... (View More)

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

This activity introduces the primary colors of light. Satellites transmit images to us as a series of numbers, and this activity is designed to show how numbers are combined to create images using the primary colors of light. Students work in groups... (View More)

Students identify the actual colors of objects bathed in monochromatic light and learn how three colors of light can be combined to produce colors ranging from black to white. Students see how space observatories make use of monochromatic filters to... (View More)

Students determine the ability of various lenses and mirrors to gather light in order to compare and calculate their light gathering power. This activity is part of Unit 3 in the Space Based Astronomy guide that contains background information,... (View More)

This is an activity about the differences in thermal behavior between similar materials having different physical properties. Learners will measure temperature of two different surfaces; sand and stone; on a sunny day, make a series of temperature... (View More)
