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)

Alaska Native (Inupiat) Elders and children living in northern Alaska share their experiences and stories about the northern lights (aurora borealis). The website features a 23 minute video and a series of shorter videos and interactive animations... (View More)

Participants experiment with ultraviolet light sensitive plastic beads, which are generally white but turn colors when exposed to UV light. They are informed about the nature and risks of UV light and are asked to explore what types of materials... (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)

This online repository includes captioned images designed to tell a story about the science of light. Developed for the United Nation's International Year of Light 2015 (IYL2015), the images showcase the incredible variety of light-based science... (View More)
