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)

This activity provides a visual example of convection in fluids. Students will record their predictions and observations on diagrams of the experimental set-up showing convection currents. Materials required include hot and cold colored water,... (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)

In this learning assessment, students demonstrate understanding of the following concepts: solids, liquids and gases, changes of state, convection, and density. Students create a skit where the actors and actresses are molecules, and dramatize,... (View More)

Materials Cost: Free per group of students

The front of this poster is a cartoon profile of the atmosphere, showing the "good and bad" roles of ozone in the stratosphere, high troposphere, mid-troposphere, and surface. On the back is an article for students, beginning with an explanation of... (View More)

In this lesson, students explore the visible light spectrum using a flashlight and red, blue and green theatrical gels or cellophane. They also record data on a worksheet, and learn about mixing wavelengths of light. A student worksheet, data sheet,... (View More)

This lesson applies the science and math of the rotation of a sphere to water and wind movements on Earth. Students are introduced to convection, the Trade Winds and the Coriolis Force. Using an online visualizer, students generate trajectories and... (View More)

This experimental activity is designed to develop an understanding that air has mass. Students conduct an investigation and observe the change in the position of a bar balancing a balloon inflated with air on one end and a uninflated balloon on the... (View More)

This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two... (View More)

This activity promotes student understanding of some of the movements that take place when warmer water and cooler water interface, and how differences in densities, resulting from variations in temperature, set molecules of liquids and gases in... (View More)
