Small stone collection with 10 different stones with different hardness according to Mohs classification (hardness 1-10). It is thus possible to determine the hardness of other stones with this stone collection. The box contains: Talc, gypsum, calcite, fluorite, apatite, feldspar (orthoclase), quartz, topaz, corundum and diamond (needle).
Student experiment using an optics bench to build telescopes for use with a viewing screen.
Spare compasses for the CASTLE Kit (EM-8624A). Perfect for investigating the magnetic fields around straight wires.
Vials contain a vacuum sealed color forming reagent to test a variety of water quality parameters. 30 individual Ammonia test vials.
Allows mounting and changing of distance between field coils and is used for studies in electromagnetism.
A 200 turn wire coil on a bobbin that has a base with three terminals that accommodate banana plug contacts for measuring current or voltage. Can be mounted on a Helmholtz base.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils.
Students can vary propeller type and diameter with this small scale wind turbine. An accessory to the Energy Transfer-Generator.
Two electrolytic, bi-polar, 25 Volt capacitors with screw terminals.
The complete solution for examining the principles of magnetic flux and conservation of energy.
The complete solution for studying standing waves driven by a variable frequency driver.
