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)

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)

This is an activity about magnetism. Using bar magnets, classroom materials, and a compass, learners will explore how bar magnets interact with one another and with other materials, use a compass to find the direction north, and use various... (View More)

This experimental activity is designed to develop an understanding that air has mass. Students conduct an investigation and observe the change in the position of a bar balancing a balloon inflated with air on one end and a uninflated balloon on the... (View More)

This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two... (View More)

This activity promotes student understanding of some of the movements that take place when warmer water and cooler water interface, and how differences in densities, resulting from variations in temperature, set molecules of liquids and gases in... (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)

This learning activity engages students in measurement of pH in water and soil samples, plants and other natural materials. By mixing different substances, they observe how pH changes, and become familiar with the pH of common household products.... (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)
