In this activity about the Sun's influence on plant growth, learners will create a plant box and observe that a plant will grow towards the Sun, its primary source of energy. By periodically collecting data on the growth of the plant, they can come... (View More)

This is an activity about the concept of direct versus indirect sunlight. Learners construct and use a sun angle analyzer to investigate the effect of angle on area illuminated. The fraction of light on each square of the analyzer is then calculated... (View More)

This is an activity about magnetic fields. Using iron filings, learners will observe magnets in various arrangements to investigate the magnetic field lines of force. This information is then related to magnetic loops on the Sun's surface and the... (View More)

Audience: Elementary school

This is an activity about Earth's magnetosphere. Learners will use a magnet, simulating Earth's protective magnetosphere, and observe what occurs when iron filings, simulating the solar wind, blow past and encounter the magnet's field. This is the... (View More)

Audience: Elementary school

This is an activity about how impacts in space increase the heat of planetary bodies. Learners will demonstrate the conversion of kinetic energy (energy of motion) to heat (thermal) energy by hammering a nail and feeling its temperature increase.... (View More)

Audience: Middle school

This is an activity about gravity in space. Learners will use water in a cup to demonstrate “weightless” conditions in free-fall. This activity is part of "Ways of Seeing," an interactive, educational CD-ROM from NASA's Cassini Program. The... (View More)

Audience: Middle school

This is an activity about gravitational fields. Learners will use rolling BBs in a magnetic field, to understand the concept of a spacecraft trying to escape a planet’s gravitational field. This activity is part of "Ways of Seeing," an... (View More)

Audience: Middle school

This is an activity about orbital speed. Learners will create an analogy to planetary orbits using weights on a string that demonstrates the farther a moon is from a planet (or a planet from the Sun), the slower its orbital speed. This activity is... (View More)
