Why Do Some Molecules Absorb Infrared Energy?

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)

Fingerprints in Sunlight Presentation and Activities

This is a set of materials about spectroscopy, including a downloadable PowerPoint presentation and two demonstrations or activities. Learners will read and/or hear about the science of spectroscopy, what a spectrum is, and how spectroscopy is... (View More)

An Inversion Model

This demonstration allows students to visualize inversion in a fluid, explain it in terms of density, and apply the concept to weather systems and convection. Materials required include four Ehrlenmeyer flasks, two thin glass plates, a heat source,... (View More)

Water Bottles, Root Beer, and Air

In this demonstration, a plastic soft drink bottle is used to demonstrate properties of gases and liquids with respect to temperature and pressure. Calculations using the formula for the Ideal Gas Law are included. The resource is from PUMAS -... (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)
