In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

In this experiment, students create a "lava lamp" - a beaker on a hotplate, and investigate buoyancy, convection and other fluid and thermodynamic properties using ink, water, vegetable oil and Alka-Seltzer tablets. The activity is from PUMAS -... (View More)

This is a lesson about discovering distant planets using an Earth-based observing technique called stellar occultation. Learners will explore how a stellar occultation occurs, how planetary atmospheres can be discovered, and how planetary diameters... (View More)

This activity demonstrates Lenz's Law, which states that an induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current. In the demonstration, an empty aluminum can... (View More)

Using three flashlights and sheets of red, blue and green cellophane, students demonstrate that white light is composed of colored light of different wavelengths. The resource is part of the teacher's guide accompanying the video, NASA Why Files:... (View More)

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 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)

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)
