Student groups are provided with a generic car base on which to design a device/enclosure to protect an egg as it rolls down a ramp at increasing slopes. During this activity, student teams design, build and test their prototype...

Dozens of statistical terms are defined and illustrated in this glossary.

Newton's three laws are deceptively simple, but they are the underpinning of all of physics and govern the mechanics all of your actions in everyday life. Take an in-depth look at these laws in this learning module.

Review the key concepts, equations, and skills for Newton's first law of motion, including the difference between mass and weight.

Balance the force of gravity with the force of the expanding gasses created by mixing baking soda and vinegar. Create a soda bottle submarine that sinks to the bottom of the bathtub and then rises back to the surface.
