Wooden Geometric Shapes - 16 Various pieces, in wooded box.

Set of 9 cubes, 25 mm side. Supplied in wooden box.

High-quality pulley can be mounted on a support rod or table.

Observe the spectral lines of mercury atoms.

Set of 12 Delrin cylindrical bars of different length but the same diameter.

Mounted on a wooden stand with a scale, the apparatus is comprised of a three-limbed glass tube with rubber tubing on the center.

Perform a quick and easy quantitative verification of Boyle's Law.

Experiment with gear ratios on your wind turbine or other small projects. Adding gears to your turbine can greatly increase the generator RPM, giving you higher power output. The small 8-tooth gear fits on 2 mm driveshafts that are found on many DC generators. The gears have a keying feature that allows them to be changed quickly and easily using the included hex locks. The hex lock secures to our 9/64 inch hex-driveshaft. Hex-driveshaft not included.

Observe the density across different materials and sizes.

This wooden machine has a sturdy wooden construction ideal for classroom use. This apparatus can demonstrate how gears can turn rotational motion into translational motion.

Set of apparatus for carrying out 10 basic student experiments on radioactivity. In a robust Gratnell tray with foam inserts molded to the shapes of the items and a transparent lid. Includes a CD with instructions for the experiments. The experiments are designed to occupy as little space as possible on the supplied base plate, while remaining clear and easy to perform. To determine the count rates, it is recommended that a Geiger counter be used (not included).

A complete photogate system for use with Visual Scientifics systems - or any lab experiment requiring photogates.

Set of 12 Polypropylene bars of different length but the same diameter.

Fourteen materials in the form of rectangular blocks.

4 Holders, 12 Al Rods, 12 Brass Rods, 12 PVC Rods, 12 Polypropylene Rods

Highly evacuated electron tube with focusing electron gun and fluorescent screen inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using the Helmholtz coil pair (not included). By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge (e/m) and the velocity of the electrons.
