Photographic diffraction objects in a slide frame.

Five single slits of different widths in a slide frame.

A must for explorations of sound and waves.

A Fascinating Demonstration!

Demonstrate Newton’s Laws and the conservation of energy and momentum with the amazing new Air Puck!

Bring the 2nd Law of Thermodynamics to life.

For physics experiments and demonstrations such as kinetic, density and volume measurements, pendulum bob, potential energy and conservation experiments, ballistics etc. Solid ball, 1-1/2" (40mm) diameter. Made of Steel. Sold as a pair. Comes with a Teacher's Guide.

Demonstrates Atmospheric Pressure.

Spectrum Tubes demonstrate the wave properties of different gases.

Explore Bernoulli's principle of air pressure.

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.

This lamp holder is suitable for miniature base lamps.

This Ballistics Cart demonstrates the independence of vertical and horizontal motions.

With the Resonance Apparatus, students investigate the effect of frequency on wavelength.

Get students into the swing of things with the Doppler effect.
