In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).

In this activity, learners make a helium balloon "flink"--neither float away nor sink to the ground. Use this activity to introduce physics concepts related to gravity, density, and weight.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.
