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.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

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.

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

In this online Flash game and spacewalk mission simulation, learners are challenged to repair parts of a space station while balancing their oxygen and fuel use carefully.

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.
