El Niño Southern Oscillation (ENSO) affects weather, climate, and, consequently, humans and their activities. In this investigation, students review and analyze ENSO background info, data and satellite images in preparation for a game. Acting as... (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 investigation introduces students to the phenomena of urban heat islands, areas of higher then normal temperatures associated with populated areas. Using Atlanta, Ga., as the study site, students begin by analyzing the population growth and... (View More)

This resource introduces the concept of wind chill, the formula used to measure it and relates it to the causes of hypothermia. A simple experiment using a pie pan, sand, fan and a thermometer demonstrates this concept. The resource is from PUMAS -... (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 Earth... (View More)

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 a lesson about light in the outer solar system. Learners will demonstrate the effect of the inverse square law of illumination with distance and connect this to the functioning of solar panels at Saturn. Requires a silicon solar cell... (View More)

This is a activity about how reaction wheels affect spacecraft orientation (attitude). Learners will observe Newton's Third Law (action-reaction) in the changes caused by a reaction wheel acting upon a spacecraft suspended from a support wire and in... (View More)
