In this short demo/activity, a balloon with baking soda in it is stretched over the mouth of a flask or bottle containing vinegar. The balloon is tipped so that the baking soda falls into the vinegar, and the reaction creates carbon dioxide, which... (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)

In this demonstration, students learn how fiber optics work by observing a model using gelatin and observing how the internal reflection of light allows light to bend within the system. The resource is part of the teacher's guide accompanying the... (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)

In this demonstration, students see how the different wavelengths of the visible light spectrum combine to make white light. Student cut circles out of poster board, color sections red, orange, yellow, blue, green and violet, suspend it in the air... (View More)

In this demonstration, liquids of different density are mixed to demonstrate how the layers of the Earth were formed as the denser materials sank to the inner portion of the Earth with the less dense materials, such as our crust, remaining on top. A... (View More)

In this demonstration, students learn that heat makes air expand and rise, and learn how pressure systems are formed by observing the creation of a convection current. A large rectangular pan, a salad dressing bottle, a small latex balloon and water... (View More)

The force of gravity is the focus of this demonstration using a ruler, string and a paper clip. Students observe that the Earth's gravity is always downward toward the center of the Earth. The resource is part of the teacher's guide accompanying the... (View More)

This demonstration allows students to visualize how heat moves through convection - using water, food coloring, a small cup and a large jar - and prompts them to make a connection between the observed process and cloud formation. The resource is... (View More)

In this demonstration, students learn that air flows from a high-pressure area to a low pressure area, and greater the differences between pressure areas, the greater the wind speed. The demonstration uses an apparatus made from two 2L beverage... (View More)
