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)

In this demonstration, sheet cakes are used to show how tectonic forces create convergent, divergent and transform plate boundaries. The resource is part of the teacher's guide accompanying the video, NASA SCI Files: The Case of the Shaky Quake.... (View More)

Wave movement is explored using a metal tray of prepared gelatin, dominoes, sugar cubes, plastic wrap and a rubber mallet, in a demonstration of physical principles supporting the study of earthquakes. The resource is part of the teacher's guide... (View More)

Slinky toys are used to demonstrate how primary (P) and secondary (S) waves travel in earthquakes. The resource is part of the teacher's guide accompanying the video, NASA SCI Files: The Case of the Shaky Quake. Lesson objectives supported by the... (View More)

In this demonstration, students learn about the physical process of liquification and how it causes the ground to become unstable during an earthquake. Required materials include a plastic tub, sand, water, a brick and a rubber mallet. The resource... (View More)

Students build a simple aneroid barometer that can be used to measure changes in air pressure. Materials required include a large jar, ruler, large balloon, 2 drinking straws, and clay. The instrument is used to track changes in air pressure, and... (View More)

In this investigation, students use a a homemade psychrometer to measure relative humidity Two metal thermometers, a small piece of cloth, string, and a timer are required materials. The resource includes a chart which students use to calculate... (View More)

In this inquiry investigation, students discover how a given amount of light changes in intensity when the area it shines on changes, and that change in light and heat occurs when the Earth is tilted towards or away from the Sun. Supplies required... (View More)
