This is an activity about Earth's magnetic field. Learners will construct a soda bottle magnetometer, collect data, and analyze the results to detect magnetic storm events. Ideally, learners should collect data for at least a month. If several... (View More)

Audience: Middle school

This module focuses on ultraviolet radiation on Earth and in space and how it affects life. Learners will construct their own "martian" using craft materials and UV beads. They will explore how UV radiation from the Sun can affect living things,... (View More)

Audience: Informal education

Learners model how the Moon's volcanic period reshaped its earlier features. The children consider that the broad, shallow impact basins contained cracks through which magma seeped up. A plate in which slits have been cut is used to represent an... (View More)

Learners model how impacts throughout the Moon's history have broken rocks down into a mixture of dust, rocks, and boulders that covers the lunar surface. They consider how the dust will continue to hold a record of human exploration - in the form... (View More)

Learners will model ancient lunar impacts using water balloons. By measuring the diameter of the crater area, they discover that the Moon's largest impact basins were created by huge asteroids. The huge basins formed on the young Moon, but through... (View More)

Learners model how an ocean of molten rock "magma" produced the Moon's oldest rocks. Dense materials in the molten mixture sank, while the least dense materials floated to the top and cooled to form the light-colored areas we see on the Moon today.... (View More)

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)

In this lesson, students observe the surface of rotating potatoes to help them understand how astronomers can sometimes determine the shape of asteroids from variations in reflective brightness.

This is an activity about modeling the apparent motion of the Sun as seen from Earth. Learners will use a flashlight, toothpick, and styrofoam model Sun to mimic the relative shadow motion produced by a sundial. The activity will help learners... (View More)
