Physics demonstration equipment is essential to understanding the concepts presented in all Physics labs. The main topics of Mechanics, Acoustics, Electricity and Magnetism, Atomic and Solid State physics all examine the natural laws of the universe. I remember the time I learned the first Law of Levers. My experience on the teeter-totter as a youth showed me that the closer I moved toward the center (fulcrum), the less I seemed to weigh. To see it quantified mass x distance = mass x distance was an epiphany.
There are many science supply companies offering good versions of air tracks, pulley systems, simple machine demonstrations, geometric optics and calorific apparatus. There is one company in the USA that has the exclusive representation for Leybold Physics. Besides covering the classic Physics topics mentioned above, the Leybold line is strongest in Modern Physics and Solid State Physics.
Main featured experiments are Millikan oil drop, Electron diffraction, Franck-Hertz experiments with Hg or Ne tubes, e/m, Electron Spin Resonance, (ESR), Rutherford Scattering Chamber, Hall Effect as well as the student, tabletop X-ray machine. This is a microprocessor controlled, 35Kv tube with an experiment chamber, designed for student use. The X-ray machine accepts 6 different anode tubes, each with distinct characteristics. The unit can be delivered with the tube of choice installed and a stepped goniometer to hold and rotate samples with a 0.01 degree steps. Besides a wide range of atomic shell experiments, the X-ray apparatus can be used with a Tomography module. This is a CCD video camera that captures 2D images as the biological specimen (freeze dried please) is rotated 360º. Then the software reassembles the images into a 3D projection capable of adjusting the intensity and the transparency so the bones and organs can be distinguished.
Given the inherent dangers associated with high voltages, X-rays, mercury and other conditions necessary make these advanced demonstrations. It is absolutely essential that the science apparatus is engineered to the highest standards. Leybold has been the leader in Physics equipment for over 100 years, with the focus on the pedagogical value in the design of the equipment. Student safety is built in with the appropriate materials and constant improvements to ensure years of rugged use.
