In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this activity, learners make their own heat waves in an aquarium.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.
