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

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 uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).

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

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

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.
