Physics demonstration films
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 video that could be used with students in the classroom. The topics covered in the videos are:
- Demonstrating diffraction using laser light
- Using an electron diffraction tube
- Using a Van de Graaff generator
- A simple wave machine
- Creating a bin-bag capacitor
- Using an oscilloscope
- Illustrating the movement of particles in Brownian motion
- Demonstrating the process of electromagnetic induction
- Compressing a gas in a fire piston
- Using a signal generator to illustrate waves and sound
- Transmission of electricity along power lines
- Creating a simple electric motor
- Static electricity and charge with an 'electric sausage'
- Gravity and the motion of projectiles with the Monkey and Hunter demonstration
- Demonstrating thermal conductivity

Bin-bag capacitor
This video shows how two metal foil sheets and a bin-bag can be used to show how a capacitor works. The metal foil acts as the plates and the bin-bag as the dielectric. The model capacitor can be charged and discharged as well as demonstrating what happens if a capacitor's working voltage is exceeded.

Oscilloscope
Produced by the National STEM Learning Centre and the Institute of Physics, this video demonstrates how to use an oscilloscope to measure potential differences that vary with time. The clip shows how to set up the oscilloscope and explains how the vertical displacement corresponds to a potential difference. The...
Brownian motion
This video illustrates how to show the movement of particles by Brownian motion. Instead of using the traditional smoke cell, the video shows how Brownian motion can be observed in a suspension containing micrometre diameter polystyrene spheres. Using a microscope and video camera, students can observe the motion...
Electromagnetic induction
Produced by StoryCog, this video demonstrates the process of electromagnetic induction. The video shows a simple piece of equipment that can readily be made which contains spinning magnets, a wire coil and a lamp. Spinning the magnets past the coil produces an electric current and lights the lamp.
