This is an activity about the Doppler effect. Learners begin by simulating the noise made by a passing siren. After learning that the change in pitch results from movement, they investigate the definition of frequency, calculate change in frequency,... (View More)

In this lesson, students explore a discrepant event when they design an experiment to measure the rate that ice melts when in pure water versus salt water. It is designed to help students realize that a carefully-designed experiment may yield... (View More)

This is a hands-on lab activity about seawater density, specifically the relationship between density of fluid, weight of an object, and buoyancy. Learners will develop hypotheses and observe a demonstration of density to understand its role in... (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)

In this laboratory activity, learners explore the difference between heat and temperature, and explore the rate of heat transfer from one substance to another as it depends on the density of the substances being investigated. The activity can be... (View More)

This is an activity about Earth's magnetosphere. Learners will use a magnet, simulating Earth's protective magnetosphere, and observe what occurs when iron filings, simulating the solar wind, blow past and encounter the magnet's field. This is the... (View More)

Audience: Elementary school

In this activity, students perform a version of the experiment of 1801, in which ultraviolet light was first discovered by Johann Wilhelm Ritter. This experiment should be conducted outdoors on a sunny day - variable cloud conditions, such as patchy... (View More)

Materials Cost: $5 - $10 per group of students

This is an activity about the existance of infrared radiation. Learners will measure and compare temperature changes due to radiation in the visible and infrared parts of the spectrum using a strong light source. This activity is part of "Ways of... (View More)

This is an activity about gravity in space. Learners will use water in a cup to demonstrate “weightless” conditions in free-fall. This activity is part of "Ways of Seeing," an interactive, educational CD-ROM from NASA's Cassini Program. The... (View More)

Audience: Middle school

This is an activity about cratering. Learners will observe and identify distinctive features of craters. This exercise will help students grasp how craters provide information about the history of the solar system. This activity is part of "Ways of... (View More)
