"Paleontology Models"

Useful for collision and pendulum experiments.

Construct a Model House Using Solar Energy

Your Students Will Shout Eureka When They Use this Simple Apparatus.

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

The Digital Photogate Free Fall Apparatus retains the precision of older models while eliminating the hassle of setting up heavy steel columns and adjusting spark recorders.

Clearly Observe Inner Workings

For class model building.

Compare How Different Gear Configurations Function

The Jolly Logic Altimeter analyzes flight altitude, acceleration, top speed, flight duration, and six other important flight statistics.

This working model hydraulic/pneumatic jack shows how hydraulic or pneumatic systems can multiply forces.

Trebuchet: the greatest weapon from the ancient world

This wooden machine is elegantly designed and easy for students to use. Study levers and mechanical advantage both qualitatively and quantitavely.
