Lenses are precisely shaped pieces of glass that have been developed and used in corrective glasses, telescopes, microscopes, binoculars, and magnifying glasses.

The Sun is our nearest star. It is a relatively small star when compared to other stars in the Universe. The Big Bang theory suggests how our Universe was created. The evidence for this is red-shift.

The nuclei of atoms contain a large amount of energy. Releasing this energy would free the world from having to use fossil fuels. There are two methods of doing this: fission and fusion.

Waves may be transverse or longitudinal. Electromagnetic waves are transverse waves with a wide range of properties and uses. Sound waves are longitudinal waves.

Energy can be described as being in different 'stores'. It cannot be created or destroyed but it can be transferred, dissipated or stored in different ways.

Turning forces are found in many everyday situations and are essential for machines to function. Levers and gears make use of these turning forces to provide an advantage.
