A set of 15 samples of different materials used to challenge students to identify materials based on measurement of their density. For some specimens this will be straightforward. In other cases, it will lead to a discussion of uncertainty in measurements and data, and to an awareness that different materials may have nearly the same density.

This track includes everything needed to demonstrate three basic concepts of physics: acceleration, collision, and force.

With the Force Mechanism Trough, students can research acceleration and the effect of gravity on a moving body by propelling steel balls or a wood block down an aluminum trough track.

The Ballistics Car demonstrates an integral law of motion.

This air track provides a frictionless surface that is indispensable for studying the mechanics of linear motion.

Investigate and experiment with seven functioning Wheel and Axle and Inclined Plane models designed to demonstrate science and technology concepts.

Students can determine, through investigation, if the machine multiplies the force it applies to the resistance (load), if the machine changes the direction of the force they apply, and more.
