Learners develop an understanding of air pressure in two different activities. They model the magnitude of air pressure as gravitational force per unit area, and they use cookie wafers to model how...

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay. They compete to find the best beam strength to beam weight ratio, and learn about the trade...

Learners examine what happens when a tube spins in two directions at once. They push on a cardboard tube causing it to spin along its length while at the same time turning from end-to-end. Markings...

Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes. When the plane is at cruising altitude, learners open and cap a empty...

With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device. This activity can be used as a lesson on...

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale. When wind pushes against a model...
