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)

This is an activity about the relation between day length and temperature. In one team, learners will create and analyze a graph of hours of sunlight versus month of the year for a number of latitudes. In another team, learners will graph... (View More)

This is a lesson about spacecraft communication. Learners will explore the concepts of "signal" and "noise" by listening to a computer-generated signal from two different distances with no additional background noise, and then with background noise,... (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 parallax. Learners will explore the concept of parallax and then simulate the discovery of Pluto with a Blink Comparator via an online interactive.

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)
