# Spinning White Light

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)

# Density Determines the Layers

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)

# Multiple Monies

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)

# How Do Higher Temperatures Affect the Water Cycle?

This demonstration shows that an increase in temperature will speed up the water cycle. One outcome will be an increase in rainfall. A second outcome will be the increase in total evaporation of water and subsequent drought. Materials required... (View More)

# What Will Happen if Climate Variability and Change Cause Glacier and Polar Ice Cap Melting?

This demonstration will show how increased temperatures will hasten the melting of ice in the environment, contributing to a rise in sea level and subsequent flooding of coastal areas. Materials required include 2 aquariums, plastic wrap, a clamp... (View More)

# How does the Make-Up of the Atmosphere Affect Temperature?

In this demonstration, students explore the concept of greenhouse warming. They determine whether an increase in the amount of heat-trappping gases in the atmosphere can cause the temperature on Earth to rise. Students compare the relative heat... (View More)

# Blue, Blue, Where Are You?

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)

# The Electromagnetic Spectrum: Wavelength and Energy

In this activity, students demonstrate the relationship between wave frequency and energy in the electromagnetic spectrum by shaking a rope to identify the relationships. This activity is part of Unit 2 in the Space Based Astronomy guide that... (View More)

# Things are Heating Up

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)

# Going Down, Anyone?

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)
