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 front of this poster is a cartoon profile of the atmosphere, showing the "good and bad" roles of ozone in the stratosphere, high troposphere, mid-troposphere, and surface. On the back is an article for students, beginning with an explanation of... (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 activity, students create their own cumulus cloud out of white paper and mount it on blue paper. Students will also complete the Cloud Fun Student Activity Sheet that includes a description of the cloud and what the weather was like on the... (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 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)

Using this worksheet as a guide, students conduct research to learn about the structure of the atmosphere. They draw a diagram, and identify the boundaries between the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. A set of... (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)
