Nondestructive Evaluation (NDE) is the process of evaluating materials to detect and measure the presence of defects without causing damage to the material being tested. In this lesson, middle and high school students are introduced to NDE,... (View More)

This video explains albedo - the concept that the brightness of the Earth system (atmosphere, ocean, and land surfaces) determines how much incoming solar energy is immediately reflected back to space. Reflected shortwave energy and land albedo... (View More)

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)

Twice each day, once during daytime and once at sunset, students observe sky color, visibility, and sky conditions over a one week period. Each observation is recorded on a sky report form (included) for follow-up discussions and comparisons. This... (View More)

Using water to represent the atmosphere and milk droplets to represent aerosols, students make predictions and conduct investigations to discover how different aerosol concentrations affect atmospheric color and visibility. This lesson is one of... (View More)

Through the use of prisms and glue sticks, this activity introduces students to a fundamental property of light: white light is made up of colors representing different wavelengths. Students use the results of the activity to explain the variation... (View More)

This short (11:29 minutes) video features NASA scientists answering a set of student-designed questions related to NASA’s Global Precipitation Measurement satellite mission. The set of twelve questions were generated after students viewed... (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)
