In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

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 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.
