Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners will explore how and why weight distribution works.

Learners build simple catapults and use them to launch cotton balls.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.
