The four specimens in this set help the students to explain the concept of the mole. The Mole set contains four element specimens: Copper, Iron, Zinc 23, and Aluminum. Each sample contains one mole, 6.02 X 1023 atoms of the element.
To understand the relationship between moments of force, the amount of force, and the length of the lever arm. Includes a meter stick, three knife-edge clamps, aluminum support, two mass hangers, slotted masses from 1 gm to 500 gm, and a storage rack.
Experiment with the effect of voltage and magnetism on the operation of a DC motor with this 4" motor model. Includes motor components, permanent and electromagnets, and assembly instructions. You provide one or more batteries (1.5-volt to 6-volt) and connecting wire.
This motor-generator set gives students an insight into the physical and technical relationships on which electric motors, generators, and transformers are based. The modular system allows to set up different function models without tools: Various DC motors Series and shunt motor Synchronous motor DC generator and alternator Transformer This set allows the performance of 10 student experiments about the following…
General purpose student bench meters with full-scale accuracy of ±2.5% and overload protection. Additional features: large 3" scale, externa zero-adjust calibration, and fully enclosed plastic case with inclined meter face. Triple range, 0-3 V (0.1 V)/0-10 V (0.2 V)/0-15 V (0.5 V).
The high-quality tuning fork set covers the octave from middle to high C. It consists of one each of 261.6C, 293.7D, 329.6E, 349.2F, 392G, 440A, 493.9B and 523.2. Set of eight, with an activator.
The set includes five blocks of the same size and mass and five steel balls also of the same size and mass. Students will be surprised to observe that the blocks and balls when combined, result in different masses in each case. The set illustrates the importance of mass distribution in determining the mass of an object
A flat glass plate and a slightly convex lens of 50 mm diam. are placed in a metal frame with three pressure-adjusting screws to produce Newton's Rings.
To demonstrate that 2 bodies will strike the floor at the same time even when their paths of flight and horizontal velocity components are different. Consists of a base, spring plunger, 2 steel balls (1 solid, 1 pre-drilled), with instruction sheet.
To demonstrate the discovery made by Newton that white light is composed of seven colors. Consisting of a pulley mounted on a metal stand, the seven colored disc is driven by gears connected to a hand driven wheel. When the colored disc rotates, the eye can’t distinguish between individual colors and perceive it as white color.
Large size to clearly explain the theory. Wooden frame consists of five nickel plated steel balls of uniform mass suspended from the frame. Includes instructions. Size: approx. 9″ L x 7″ W x 8″ H.
To show the action of electric current on a magnet. A 75 mm cobalt steel needle supported on a pivot is mounted on the base and is surrounded by a copper strip rectangle with two terminals.
The charge is indicated by the deflection of an aluminized plastic straw which rotates freely on the saddle of the conducting rod. A scale on the instrument’s back is graduated in degrees to allow measurement of the deflection. The conducting rod is recessed in the metal housing to shield against air currents. With replacements aluminized straws.
Used for experiments in density and specific gravity, Archimedes' principle, and more. Sturdy aluminum construction. The Overflow Can measures 5" H x 4" diam and includes a spout
Complete demonstration of Pascal’s Law. The apparatus shows that a change in pressure in fluids is transmitted equally in all directions to all parts of a fluid. The device contains a hollow sphere connected to a hand pump with a plunger that applies pressure to the fluid in the ball. The fluid exits all 10 equidistant nozzles in the ball…
Approximately 28 cm long clamp designed to hold 3 pendulums, all pendulums can be individually adjusted without disturbing the others. With knurled thumbscrews to keep suspension cords secure.
Demonstrate how to string length and mass affect the movement of a pendulum. Simply attach strings of different lengths with different weights to the pendulum clamp and observe the differences in motion. Includes a heavy-duty pendulum clamp, a support stand with a 6 in. x 11 in. support base, and a 36 in. L rod, four 25 mm pendulum bobs…
