Photoelectric Effect
Produced by the National STEM Learning Centre and the Institute of Physics, this video demonstrates how to use a gold-leaf electroscope, zinc plate and an ultraviolet light source. The zinc plate is placed onto the top of the electroscope and it is given a negative charge.
The electroscope can be discharged...
This series of videos have been produced by the National STEM Learning Centre and the Institute of Physics. They are mostly aimed at teachers and illustrate how to perform simple demonstrations and use particular pieces of equipment. Some topics have versions of the...
Power lines
Alom Shaha shows a demonstration that can be used to illustrate power transmission and why high voltages are used to minimise power loss. This video is aimed at teachers...
Signal generator
This video demonstrates the use of a signal generator to illustrate waves and sound. The video shows how features such as frequency, amplitude and wave form can be demonstrated using a loudspeaker and an oscilloscope.

Thermal conductivity
These two short videos, produced by the National STEM Learning Centre, illustrate the process of thermal conductivity. The first video shows a demonstration of thermal conductivity using ice, plastic and aluminium...
Van de Graaff generator
This video is aimed at teachers and shows how to get the best out of a Van de Graaff generator. In the video, Michael de Podesta explains how the generator works and gives some tips on getting consistently good results when using the apparatus. The video concludes with a simple but effective demonstration of charge...
Wave machine
In this video, Alom Shaha describes a simple but effective wave machine. Aimed at teachers, this video explains how to make the wave machine using adhesive tape, jelly babies and wooden skewers. He explains how it can be used to illustrate transverse wave motion in a visual and engaging manner.
