Students explore various aspects of mass using a double pan balance, colorful stacking masses, and everyday items.

How Much Space Does This Take Up?

Five-piece equal mass density set – for specific heat experiments and more.

Set of three measuring pitchers with handles includes cup (8 oz/250 ml), pint (16 oz/ 250 ml), and quart (32 oz/1000 ml).

The U.S. Customary (or English) SAFE-T Weights™ have the same features as the Metric SAFE-T Weights™.

58 Colorful Metric Weights.

This set includes a set of four Measuring Jars with Caps, set of three Measuring Pitchers, set of five Measuring Cups, and set of five Measuring Spoons.

Students learn about different measurement systems, fractions, length, weight, volume and a whole lot more with these books.

Designed to illustrate that height is proportional to mass, when diameter is uniform. Set consists of 52 identified masses which are molded to stack. Included are 4 yellow 10 g masses, eight red 5 g masses and 40 blue 1 g masses.

Base 10 decimeter cubes. Units are 1×1×1 cm and larger pieces are scored to show units.

Demonstrate the Relation of Length, Area, and Volume

A perfect cubic decimeter box that contains exactly 1 liter. Can be used to demonstrate the metric relationships among linear, volume, one and mass measurements.

WARNING: CHOKING HAZARD - Children under 8 years can choke or suffocate on uninflated or broken balloons. Adult supervision required. Keep uninflated balloons from children. Discard broken balloons at once. (2) Item contains latex, which is known to cause allergic reactions. Use with caution.

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/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.

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.
