This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

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.

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

In this activity, learners investigate passive solar building design with a focus solely on heating.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.
