In this field activity, students learn about the five soil-forming factors and their influence on soil properties such as moisture, temperature, color and texture. They identify factors such as slope, shade, plants and compaction, and investigate... (View More)

In this hands-on activity, students create a model soil profile in a two-liter beverage bottle, time the movement of water through different soils and observe the amount of water held in these soils. They observe the filtering ability of soils by... (View More)

In this hands-on activity, students conduct bottle experiments to learn about the conditions that best facilitate the decomposition of organic material in soil. In the lab, they observe changes in the decomposition of vegetable scraps by varying the... (View More)

In this demonstration activity, a piece of toast, sandpaper, marbles and a spray bottle of water is used to demonstrate the creation of regolith. Regolith is the loose, unconsolidated sediment that forms from weathering of bedrock on Earth and... (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)

Students experiment with a model system made from a wooden block, sandpaper, a thumbtack, and a rubber band to understand earthquakes. In this system, the rubber band stores energy until it accumulates enough energy to overcome friction and move the... (View More)

This student worksheet provides a word find puzzle as a review of scientific terms associated with tectonic activity. The resource is part of the teacher's guide accompanying the video, NASA SCI Files: The Case of the Shaky Quake. Lesson objectives... (View More)

This resource provides illustrations showing how the coastline of California will change in response to the movement of the Earth's plates. Students assemble the illustrations to create an animated flip book. The resource is part of the teacher's... (View More)

In this demonstration, an egg is used as a model of the Earth. The egg is tapped gently, to create cracks in the shell. The pieces of shell are analogous to the Earth's plates, and the cracks are used to explain plate boundaries. Using the egg, the... (View More)
