This demonstration shows that similar-appearing lights can be distinctly different, suggesting that the light emitted is generated in different ways. It requires some advance preparation/setup by the teacher and three recommended sources of orange... (View More)

This textbook chapter traces the historical development of the modern scientific understanding of light, and reviews the electromagnetic spectrum and the Earth's atmospheric shield. The resource includes links to current news articles, and a suite... (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)

This booklet with companion videos introduces electromagnetic waves, their behaviors, and how scientists visualize these data. Each region of the spectrum is described and illustrated with examples of NASA science.

Students simulate the process of remote sensing by using common materials to represent Earth’s different ground coverings and a light meter to represent satellite instruments. The concept of albedo and its importance in Earth’s radiation budget... (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)

In this kinesthetic activity, students take on roles of either photons or gas molecules. Photons signal a change from visible light to infrared with a piece of folded construction paper, simulating absorption by the Earth's surface and reradiation... (View More)

In this problem set, learners will analyze a table on the reflectivity of various substances to three kinds of wavelengths in order to answer a series of questions. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to... (View More)

In this problem set, learners will analyze a graph of the reflectivity of soil and two kinds of vegetation to understand how scientists use these measures to identify different materials. Answer key is provided. This is part of Earth Math: A Brief... (View More)

This experimental activity is designed to develop basic understanding of the relationship between the angle of light rays and the area over which the light rays are distributed, and the potential to affect changes in the temperature of materials.... (View More)
