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...

A song that explains ionic, covalent and metallic bonding in simple terms. 

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...

In this resource, students use their STEM skills to help them design and build a model of a flood- proof house. Activities to help them with their design include testing materials (for strength and absorbency) and structures. Set on a fictitious island coping with the devastating effects of flooding caused by...

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

This includes descriptions of:

• Hubble's observation of a red...

Produced by Twig, this animated video is a clear and accessible explanation of how the Solar System fromed. The video describes how:

* the solar system grew from a ball of gas which formed the Sun

* gravity caused heavy material to cluster together and eventually form planets

* the inner...
