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

Diffraction of laser light

In these short videos, Michael de Podesta explains how a laser can be used to show the diffraction and interference of light. Using a laser pen in the classroom, the wave nature of light is demonstrated as a thin wire is used to generate an easily-seen interference pattern.

Two versions of the video are...

Electron diffraction tube

In this video, Alom Shaha explains the elements of an electron diffraction tube and how to use one to demonstrate a diffraction pattern. The video is aimed at teachers but it could also be used with older students to illustrate the working of an electron diffraction tube.

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.
