Rolling Returns
Source Institutions
In this activity, learners build a special rolling can that returns back to you when you push it forward. Use this activity to demonstrate the transfer of energy between kinetic and potential energy.

Wilberforce Pendulum
Source Institutions
In this activity, learners build a Wilberforce Pendulum, a special coupled pendulum in which energy is transferred between two modes of vibration, longitudinal ("bounce') and torsional ("twist"), on a

Bouncing Yo-Yo
Source Institutions
In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

Downhill Race
Source Institutions
In this activity, learners explore how two cylinders that look the same may roll down a ramp at different rates.
Water Motor
Source Institutions
In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

Blowin' in the Wind
Source Institutions
In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.
