In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

Using simple, inexpensive items, learners build and test submarine models.

This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.
