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
