In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

In this physical activity, two lines of learners link hands and arms to model a beam subject to various loading schemes.

Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.

In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.

In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

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

In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.
