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 is an activity about photosynthesis. Learners will use the basic principle of photosynthesis and investigate how light intensity diminishes as a function of distance from the light source. Questions help them connect these two ideas to... (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)

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)

Using a constructed Mystery Light Box, learners will observe what is in the box without removing the object from the box, shining a light into the box, or reaching hands into the box, and they will draw what they see. Next, they will brainstorm... (View More)

This is an activity about the use of light to learn about space. Learners will use colored filters to examine slides of stars and nebulae. These filters show how astronomers distinguish stars of different temperatures and nebulae with different... (View More)
