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 explore how the hull shape impacts a ship's performance and stability.

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.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

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 build a nanorover model using styrofoam meat trays and a balloon.

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

In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

Learners will build and experiment with their own windmills made from simple household materials.

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.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this Bob the Builder(TM)-themed activity, learners explore what it means to work together as a team.

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

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

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.
