This video begins by showing a demonstration of total internal reflection (TIR) through a semi-circular glass block.

It develops an understanding of TIR by showing that as the angle of incidence (θ_i) increases so too does the angle of refraction (θ_r).  Eventually, as  θ_i is...

This video shows how interference from two sound wave sources can produce both constructive (louder sound) and destructive (softer sound) interference patterns.  A demonstration using microwaves reinforces this idea. Microwaves are generated and passed through a double slit.  The resultant interference of waves is...

Produced by the Wellcome Trust, these resources include an interactive evolutionary tree and a video of the Tree of Life. These materials will help students to find out more about the work of Charles Darwin and evolution. The resources contain:

Tree of life video: The video is a short...

This video explains how atoms are the fundamental building blocks of all matter and that they are made from sub-atomic particles (proton, neutron and electron). The simple structure of a hydrogen atom is made from plasticine. The video explains how adding a neutron to the hydrogen atom does not change its...

Much of this video shows how many people do not understand how the seasons are caused.  There is a small section at the end that attempts to clarify the cause.  

This challenging video takes a philosophical approach to discussing what information is. It begins by equating information to entropy. Entropy is explained as the degree of order or alternatively randomness that exists. Examples of ordered information are the arrangement of molecules in DNA, letters in words and...

This video considers peoples’ understanding of gravity and through these ideas shows that it is a force of attraction between masses.  Some of the detail is covered in other Veritasium videos.

This video explains the term spin.  It introduces the idea of a magnetic dipole in electrons and shows how, in an external magnetic field, electron spins can be aligned or opposed (different quantum states).

However, when considering just two electrons coupled together the possible quantum positions becomes...

This is a video that asks young adults their opinion of nuclear power being used in Australia.  90% of Australia’s power derives from coal and gas. There are no nuclear power stations.

The comments from audience could be used to initiate similar discussions for the UK.

This video uses two oppositely charged metal plates to demonstrate that a candle flame contains ions. Positive ions are attracted to the negative plate, while negative ions the positive plate. Even when the candle is extinguished, the smoke is attracted to both plates and so must also contain ions.

The video asks students to predict when a bungee jumper experiences maximum acceleration.  The answer is at the very bottom of the jump.  This is often counter-intuitive as the velocity at this point is almost zero. 

However, acceleration is the rate of change of velocity over time, a = ^Δv/_Δt...
