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).
Designed for experiments involving low light level conditions. ScienceWorkshop version.
The complete solution for examining the principles of magnetic flux and conservation of energy.
Allows mounting and changing of distance between field coils and is used for studies in electromagnetism.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils. 200-turn coils.
A 2000 turn wire coil on one end of a wand that has two terminals at the other end to accommodate banana plug contacts, permitting easy connection of an electric circuit.
Students can vary propeller type and diameter with this small scale wind turbine. An accessory to the Energy Transfer-Generator.
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.
Teach the science and technology of waves and sound. Harmonic motion, waves, sound, period, frequency, resonance, interference and more.
Vials contain a vacuum sealed color forming reagent to test a variety of water quality parameters. 30 individual Phosphate test vials.
