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 Catalyst article discusses what physics is. Physics is a subject which seeks to answer fundamental questions about the nature of matter and the Universe in a self-consistent way.

The article is from Catalyst: Secondary Science Review 2015, Volume 26, Issue 1.

A song that explains what electricity is and states some of its uses. 

This resource, from the Royal Observatory Greenwich, introduces students to how our understanding of gravity has changed over time, and what this means for the gravitational field strength of different bodies in our galaxy.

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 very basic video shows what people believe water is.  It might be useful as a discussion point.

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.

Produced by the Royal Observatory Greenwich, this booklet introduces the concepts of dark matter and dark energy. Included is an online video that discusses how the Universe will end, including the role of dark matter and energy. The booklet describes the composition of the Universe, this is followed by questions...

The aim of this investigation is to find the value of a number of resistors using a Wheatstone bridge.  Although this is an historical piece of equipment that has been superseded by modern methods it provides an excellent way to understand potential difference in circuits.

Sports engineers from Sheffield Hallam University and Frazer Nash are helping Team GB's wheelchair paralympians fine-tune their equipment and training regimes using advanced analysis technology. Engineers explain the relationship between science and engineering in disability sports and how inspiring it is to work...

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...
