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.

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

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

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

In this engineering design challenge, learners build an air-powered spinning machine.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this activity, learners explore rocketry and the principals of space flight.

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

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
