In this activity, learners build an old-fashioned paddle boat out of simple materials.

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

This fun video explains how to make a batch of oobleck (or slime) and why this special substance is known as a "non-Newtonian" fluid. Watch as Mr.

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds.

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

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

Learners develop an understanding of air pressure in two different activities.
