Measurement Learning Activities
Explore key mathematical concepts using practical demonstrations of probability, counting, measurements in metric and imperial units, graphing, geometry, and more. Many kits come with supplies for teaching entire classrooms of students, complementing a wide range of teacher curriculums. Sturdy storage bins allow for packaging educational materials in a convenient, plastic, stackable bin. Counting principles are reinforced with everyday uses such as telling time, using simple materials that are safe for use by children of almost all ages.
Mass With a Balance Activity
Students explore various aspects of mass using a double pan balance, colorful stacking masses, and everyday items.

Laser Reflection Sensor
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.

Vibration Generator
Vibration generator for exciting oscillating and waves mechanically, such as in coil springs, a rubber cord, a wire ring or a Chladni plate. In robust plastic housing including mounting pin with 4mm socket for attaching accessories (Chladni plates, resonance wire, rubber band, etc.). Including holder for stand rod (up to 8mm dia.) on the rear side of the apparatus for the demonstration of standing waves in a coil spring. The generator is equipped with overload protection and is driven by a loudspeaker for smooth oscillations and fine travel stepping.

Digital Counter
Digital counter/timer for measuring duration of motion, transition times, periods, pendulum periods, frequencies, as well as for counting events or Geiger tube pulses. Includes a speaker that can be turned on and off, and power supplies for direct connection to light barriers. For event counting, a fixed counting period can be programmed in a range from 0.1ms to 99999s. Counter events (e.g. start or stop) can either be triggered by a signal to the input sockets or manually via switches. The unit includes a plug-in power supply.
