This is a lesson about visual spectra. Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or... (View More)

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 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 is an activity about motion in a frame of reference. Learners will develop an understanding that motion is relative by reading the text "Frames of Reference." As a follow-up to the reading, students engage in a writing-to-learn strategy that... (View More)

Audience: High school

This is an activity about the electromagnetic spectrum and how light is split into its component frequencies or colors. Using a diffraction grating, learners will observe four different light sources and sketch their spectra. This activity requires... (View More)

Keywords: Doppler effect
Audience: Elementary school, Middle school, High school
Materials Cost: Free

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 is an activity about the electromagnetic spectrum and how the different wavelengths of light are used to capture the most complete picture of objects in space. Learners will view images of our galaxy in multiple wavelengths to compare and... (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 activity demonstrates Lenz's Law, which states that an induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current. In the demonstration, an empty aluminum can... (View More)
