Show your students how the rate of acceleration of an object depends on the angle of incline with this great hands-on activity.

Identify All Three Classes of Levers and Their Key Parts

WARNING: CHOKING HAZARD–Small Parts. Not for children under 3 years due to small parts and small balls.

Rectangular blocks in a variety of sizes and are designed for use as an index of refraction plate.

Demonstrate the Relation of Length, Area, and Volume

Sensor for triggering the digital counter in time measurements on moving objects. Suitable for opto electronic scanning of light and dark markings on moving objects or in conjunction with a reflecting foil to form a wide spaced obstruction sensor. The intensity of the laser beam is adjusted automatically according to the distance of the object. Includes reflecting foil, stand rod with screw thread, and connector lead with 8 pin miniDIN plugs.
