Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

Learners take on the role of environmental engineers as they design water filters.

Learners play the role of materials engineers as they test the flexibility of different materials.

In this activity, learners explore the engineering and principles behind working elevators.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

In this engineering activity, learners design and build a mechanical arm to lift a small item.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this activity, learners explore how engineers have developed sorting systems which integrate into manufacturing and packaging processes. Learners explore how coins are made.
