In this activity, children use common craft materials and ultraviolet (UV)-sensitive beads to construct a person (or dog or imaginary creature). They use sunscreen, foil, paper, and more to test materials that might protect UV Kid from being exposed... (View More)

In this science-based storybook, students Anita, Simon, and Dennis want to know why the sky isn't always blue. They learn that there's a lot more than air in the atmosphere, which can affect the colors we see in the sky. Four activities accompany... (View More)

This activity demonstrates optical properties of water: that different constituents in water affect the transmission, absorption, and scattering of different colors in the visible light spectrum. Inexpensive, off-the-shelf components are used to... (View More)

Learners will use an inexpensive, simple spectrophotometer to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples. Clear water is used as the “control,”... (View More)

Students use a dipole magnet and compass to model and map Earth's magnetic field. They then induce a magnetic field to represent a Ring Current in order to observe the response to a fluctuating electric current caused by a solar storm. The lesson... (View More)

This brief (1:46) video explains the stratospheric ozone layer and its role in absorbing harmful UV radiation from the sun. The visualization shows how the thickness of the ozone layer varies with air flow aloft and seasons, and where the biggest... (View More)
