30" Van De Graaf Generator from Winso
$499.00
Create Your Own Lightening or Hair Raising Experience -- A science class staple, the Van de Graaf generator is an electrostatic machine that uses a moving belt to accumulate very high voltages on a hollow metal globe. Named after the American physicist of the same name, this generator can be used to perform electrostatic experiments on a spectacular scale. -- This generator relies on high quality rugged construction for its long life and has a 10GÇ¥ diameter metal sphere. The column between the base and sphere that houses the belt is clear lucite; the generator comes with one extra belt. -- The variable speed motor can be used to vary the rate of charge build-up and has a control knob on the base of the generator, near the on/off switch. Designed for operation on 120V, ac, with a three wire grounded cord, it is capable of generating sparks 8GÇ¥ GÇô10GÇ¥ long! -- For more information on this exciting science phenomenon, check out the Wikipedia entry .

CENCO Quantum Particle in a Box Demonstration
$99.95
Cutting-Edge Nanotechnology at Home -- This innovative apparatus is really impressive! The usability and affordability of Quantum Particle In a Box allows you to complete a series of experiments and demonstrations involving quantum mechanics and artificial atoms on your own. -- This unique kit includes a set of four removable vials in an aluminum casing. When illuminated by and LED source of roughly 405 nm the different vials radiate four distinct wavelengths. These wavelengths are dependent on the size of the quantum dot, or nanobead, suspended in the solution. -- The physical size of the quantum dots effects the wavelengths they can absorb and emit. -- Measuring the emitted wavelengths with a digital spectrometer allows you to calculate the actual size of the quantum dot using Schr+¦dinger's equation. And, placing the vials in a spectrophotometer allows the absorption of the different solutions to be compared and contrasted.

Density Blocks
$17.50
This density block set lets you examine mass vs. volume in oak, pine, PVC, acrylic, aluminum, copper, steel and brass. Observe that although each block is the same size, the mass of each block is different because the density of each substance is different. -- Instructions are included for three data gathering activities using the blocks. The set contains enough materials for one lab station. Includes: storage box and teacher's guide with three activities.
