In this activity, learners explore work, forces, simple machines, and construction. This lesson guide includes simple ways to demonstrate these principles as well as hands-on activities.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
