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 explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

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 activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this activity, learners build water-propelled engines from soft drink cans.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.
