In this introductory activity, learners investigate and discuss infrared images of various everyday objects, such as toasters, hairdryers, and running water, to learn about infrared imaging. Student questions about the false-color images help guide... (View More)

This is a lesson about discovering distant planets using an Earth-based observing technique called stellar occultation. Learners will explore how a stellar occultation occurs, how planetary atmospheres can be discovered, and how planetary diameters... (View More)

In this lesson, students explore the visible light spectrum using a flashlight and red, blue and green theatrical gels or cellophane. They also record data on a worksheet, and learn about mixing wavelengths of light. A student worksheet, data sheet,... (View More)

In this activity, students experience a demonstration of light scattering that explains the blue colors in the Intersetllar Medium (ISM) nebulae, and the reddening of stars viewed through the ISM. It also explains the blue appearance of the sky on... (View More)

Using three flashlights and sheets of red, blue and green cellophane, students demonstrate that white light is composed of colored light of different wavelengths. The resource is part of the teacher's guide accompanying the video, NASA Why Files:... (View More)

In this activity, teachers set up five stations to provide students an understanding of light refraction, using water, microscope slides, beakers, a coin, and eyedroppers. Students rotate through the stations and record their observations on a data... (View More)

In this kinesthetic activity, students observe the relationship between energy and the frequency of waves transmitted through a rope. A rope and a slinky are used in this activity. The resource is part of the teacher's guide accompanying the video,... (View More)

In this laboratory activity, students create secondary colors by mixing primary colors. Food coloring, test tubes, and a test tube stand are used. The activity is composed of a student handout with directions and a data sheet. The resource is part... (View More)

In this demonstration, a flashlight, mirror, water and a plastic shoebox are used to refract light into its component wavelengths, seen as colors of the visible spectrum. Students create a drawing of the sequence of colors in the rainbow. The... (View More)

In this demonstration of the properties of light, two small mirrors and a dime are used to show students understand how optical illusions can be created. The resource is part of the teacher's guide accompanying the video, NASA Why Files: The Case of... (View More)
