In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

In this activity, learners build water-propelled engines from soft drink cans.

In this activity, learners determine whether thermal energy can be used for work.

In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.

In this activity, learners explore how watermills have helped harness energy from water through the ages.

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

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

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

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.
