This model demonstrates convection currents and uses water, food coloring, a cup of very hot water and a votive candle as heat sources. Movie clips of demonstration setup and convection in action are provided. This activity is supported by a... (View More)

In this laboratory activity, students observe what happens when a fluid of one density is placed in a fluid of a different density. The fluids are salt water and fresh water, cold water and warm water. They generalize their results to describe what... (View More)

The purpose of this investigation is to understand the change that takes place when water condenses from a gas to a liquid, and how a change in pressure affects this transformation. Materials needed for the experiment include a large (2L) soda... (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)

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 activity, students create a model of sea floor spreading using two sheets of white paper and a metric ruler. The paper strips are pulled through a slit representing a mid-ocean ridge and divergent plate boundary. The model mimics how molten... (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)

In this activity, students use the P and S wave data to locate speed of wave travel and derive the epicenter of an Earthquake. The resource includes a U.S. map, a graph, and seismic data. A drawing compass is required to complete the activity. The... (View More)

This resource contains instructions for building a seismometer to record movements of the Earth's crust using a cereal box, string, a paper cup, strips of paper, and weights, such as marbles or washers. The resource is part of the teacher's guide... (View More)

Students become familiar with strike-slip faults, normal faults, reverse faults and visualize these geological structures using cardboard or a plank of wood, a stack of books, protractor, and a spring scale. The resource is part of the teacher's... (View More)
