This demonstration will show how increased temperatures will hasten the melting of ice in the environment, contributing to a rise in sea level and subsequent flooding of coastal areas. Materials required include 2 aquariums, plastic wrap, a clamp... (View More)

In this demonstration, students explore the concept of greenhouse warming. They determine whether an increase in the amount of heat-trappping gases in the atmosphere can cause the temperature on Earth to rise. Students compare the relative heat... (View More)

In this activity, students use the binary number system to transmit messages. Two flashlights are used to demonstrate how astronomy spacecraft to transmit images and other scientific data to Earth. This activity is part of Unit 4 in the Space Based... (View More)

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)

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)

Students understand how satellites are placed in orbit by launching marbles into space, using two plastic rulers and clay. They describe the forces that determine the trajectory of flight. The resource is part of the teacher's guide accompanying the... (View More)

This demonstration allows students to visualize how heat moves through convection - using water, food coloring, a small cup and a large jar - and prompts them to make a connection between the observed process and cloud formation. The resource is... (View More)

In this demonstration, students learn that air flows from a high-pressure area to a low pressure area, and greater the differences between pressure areas, the greater the wind speed. The demonstration uses an apparatus made from two 2L beverage... (View More)

This is an activity about light and its component colors. Learners will observe a photograph of a rainbow and make observations about what they see in the photo. Next, they will observe a rainbow spectrum and draw the rainbow using crayons. Finally,... (View More)

Audience: Elementary school

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)
