This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

This lesson focuses on graphene and its electrical properties and applications.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

This lesson focuses on how materials behave differently as their surface area increases.

In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.
