Learners construct an electricity-generating wind turbine out of a plastic bottle.

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

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.

This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

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

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

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

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.
