Compares thermal expansion of various liquids.

A fascinating demonstration!

Four different metal cylinders each measuring 38 mm long x 10 mm in diameter.

Unlike traditional pendulums, the Kater's pendulum center of gravity does not have to be know in order to determine the acceleration due to gravity.

Wide range of cubes for density experiments.

Compact kit for vacuum filtration.

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.

Visually illustrate the difference in specific heat.

Essential supplies to build and measure electric circuits.

With this classic AP chemistry experiment, students predict the outcome of stressors.

Steel tuning forks for physics experiments.

Demonstrate the classic free fall experiment in a vacuum.

Calculate density the old school way, measuring the net force acting on a submerged object.

Observe the spectral lines of mercury atoms.

With this kit, the intangible, nanoscopic world becomes accessible with hands-on experiments using both scaled-up models and real nanomaterials.

The rolling friction car kit provides four cars for exploration into the force of friction. Each car provides a set of different material wheels (wood, fabric, soft rubber, soft silicone) with a different coefficient of friction. By setting the cars in motion with equivalent velocities, one can qualitatively demonstrate the frictional properties of rolling without slipping.
