Force Mechanism Trough
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.
Collision Track
This track includes everything needed to demonstrate three basic concepts of physics: acceleration, collision, and force.
Density ID Set
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.
21st Century Balance
This balance is the first major advancement in teaching simple machines in decades.
Acceleration Trolley
Show your students how the rate of acceleration of an object depends on the angle of incline with this great hands-on activity.
Torsion of Metal Rods Apparatus
Torsion of Metal Rods Apparatus shows students the affect of a torque on a metal rod.
