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.

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...

Produced by Rolls-Royce, this entertaining video clip takes the form of an animated rap which describes a range of career opportunities open to students with skills in science, technology, engineering or mathematics (STEM). It makes a good...

The video begins by showing the many misconceptions that people have concerning the Earth’s formation.  It then explains that the Earth was formed from elements formed in stars.

The video begins by demonstrating the many misconceptions people have about the source of the sun’s energy. Using water-filled spheres, collisions between protons are modelled and the creation of energy and helium nuclei. The equation E=MC² is introduced and is used to show that mass is converted into...

A basketball and a 5kg medicine ball are dropped simultaneously. Which one hits the ground first? It seems obvious that the heavy one should accelerate at a greater rate and therefore land first because the force pulling it down is greater. But this is forgetting inertia - the tendency of mass to resist changes in...

This activity enables teachers to introduce the work of the Environment Agency into their lessons and deliver elements of the national curriculum and is designed to be delivered either by a ...
