In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

Learners build a small rocket using a matchstick and a piece of aluminum foil. A second, lit match launches the match rocket. This activity involves fire; adult supervision required.

In this activity, learners write a secret message in "invisible ink" and then use chemistry to view the writing.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.

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.
