This video provides an introduction to waves which looks at the differences between types of wave.  It would make a good revision video which discusses mechanical and electromagnetic waves with examples of each, with how particles and fields fit into the topic.  They presenter also demonstrates the difference...

This video demonstrates how a 19kg flywheel, attached to a 1 metre shaft can be lifted easily when the flywheel is spinning, yet almost impossible when stationary. It appears that the rotation reduces the weight of the...

This video asks the question, “When are you lightest?”.  Most people state that this is in the morning.  An experiment is conducted to find out. This shows that there is a loss in mass in the morning.  The question is then, “How does the body loose this mass?”.  The answer is a combination of water loss and the...

This video explains the concept of gravity and why everything on the International Space Station appears to float.

Dr Claire Cousins and Mark Fox-Powell explain how scientists look at life that exists in extreme environments on Earth, to see what kind of life scientists might see on the surface of Mars.  This knowledge helps scientists plan the best target for a rover.

Professor Cockell takes us through the astrobiology...

Astrobiologist Dr. Lewis Dartnell talks from the Atacama Desert about a research trip to find extremophiles that might give scientists some clues as to the kind of life that may exist on the surface of Mars.  Lewis shows how quartz can act as a natural sunscreen to enable cyanobacteria to grow in the dry desert...

Dr. Mark Woods explains how the rover technologies must be partly autonomous, since the signals from Earth to Mars take too long for every command to be send from Earth.  The technologies developed for space, also have applications on Earth.

This video is part of a series of ten which look at the one of the...

This video introduces an interesting problem of two balls placed in beakers of water.  A ping pong ball is fixed to the bottom of one beaker of water and an acrylic ball suspended into another beaker of water.  Both beakers contain the same amount of water and both balls displace equal amounts of water (they have...

Produced by Twig, this animated video looks at evidence for the Big Bang Theory.
