In this demonstration, a flashlight, mirror, water and a plastic shoebox are used to refract light into its component wavelengths, seen as colors of the visible spectrum. Students create a drawing of the sequence of colors in the rainbow. The... (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 of the properties of light, two small mirrors and a dime are used to show students understand how optical illusions can be created. The resource is part of the teacher's guide accompanying the video, NASA Why Files: The Case of... (View More)

In this activity, students observe how elastic rebound creates waves, using an apparatus consisting of a plastic tub and paint stir stick. The resource is part of the teacher's guide accompanying the video, NASA SciFiles: The Case of the Shaky... (View More)

In this activity, students build a model system using a rectangular pan, clay, craft sticks and water, and learn that energy is required to initiate waves and demonstrate that frequency is the number of waves that pass a given point in a certain... (View More)

In this activity using an open space and a thick rope, students simulate the movement of photons from the Sun. The resource is part of the teacher's guide accompanying the video, NASA Why Files: The Case of the Mysterious Red Light. Lesson... (View More)

This classroom demonstration employs a jar, milk and a flashlight as a model system to demonstrate that light maintains its direction of motion until it interacts with an object or substance, and how atmospheric aerosols scatter light. The resource... (View More)

Pressure, temperature and density, and resistance are characteristics of air demonstrated using a 2L beverage bottle, a coffee cup, newspaper and cardboard. The demonstration is part of the teacher's guide accompanying the video, NASA Sci Files: 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)
