This resource presents some real seismic data recorded before a volcanic eruption and allows students to locate some of the resulting earthquakes by use of graphs and maps.

This video demonstrates how adiabatic compression of air can produce enough heat to ignite cotton wool.  The auto-ignition temperature of cotton wool is approximately 400⁰C.  The video could be used to explain the way diesel engines work.

This video demonstrates that objects accelerate towards the ground at the same rate when in a vacuum.  Acceleration due to gravity is constant for all objects.

This multimedia package was developed by the Gatsby Science Enhancement Programme to help students understand the interesting and unusual properties of a range of fluids, semi-solids and solids. Published originally as a CD-ROM, the materials contain a collection of...

This video begins by introducing the three forms of potential energy (gravitational, electric and elastic). The formula Ep=mgh is derived by applying Newton’s second law (F=mg) and work done (w=Fs).  

This video introduces common misconceptions about radiation.  It then discusses the types of radiation that exists and considers how harmful they might be to us.  Our exposure to background radiation is discussed.

This video shows how collaboration between physicists and biologists has solved the mystery of how a chameleon changes its colour. The colour changes are due to light diffraction and interference patterns. Nano-sized particles in the chameleon’s skin can be distributed so selectively reflect different wavelengths...

This video compares the language used by classical computers (0 and 1) with that used by quantum computers (qubits).  Qubits can be photons, nuclei or electrons.  In this video the use of electrons is explained as follows.  To be able to measure something it must change and for electrons their ability to occupy...
