This classic Apollo 15 clip, from Footagevault, demonstrates that the mass of an object does not affect the time it takes to fall when dropped in a vacuum. The clip could be used in key stage three and four lessons on forces.

This Catalyst article investigates the healing of the ozone layer. The ozone layer in the upper atmosphere was damaged by CFCs, used in refrigeration. A ban on their use has allowed the layer to start recovering.

This video applies physics to explain how trees can move water up their trunks over 10m, which is the natural limit of sucked water. The ideas of transpiration, osmotic pressure and capillary attraction are considered.  The explanation shows how a negative pressure is be obtained from the intermolecular forces and...

The video explores people’s understanding of what light is. A wide range of misconceptions and incorrect ideas are given. Newton thought that light consisted of particles, whereas Huygens thought light was a wave. Using a cardboard box to recreate Thomas Young’s double slit experiment the wave properties of light...

Produced by the Royal Observatory Greenwich, this booklet introduces the Drake equation. The Drake equation is used to estimate the number of planets in the Milky Way that have intelligent life. Included is an online video that discusses what is required for life and where and how we might look for it. The terms of...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Describe what a light ray represents
• Describe the direction in which light travels from a light source
• Describe how light rays are emitted from each point on an extended...

This Catalyst article questions how heavy rocks can slide across a dry lake bed. The author introduces some theories to explain this phenomenon.

A statistical graphic from the Gatsby Foundation which demonstrates the chronic shortage of physics teachers across the UK and which looks at the various campaigns to address this shortfall over the past few years.

This video demonstrates the Coriolis effect. However, explains that much of what we see in terms of rotating water in either the northern or southern hemispheres is mostly due to other angular momentum sources in the body of the water.

An explanation of the Coriolis effect uses a scientific model (thought...

This video begins with the mnemonics Very furry lambs and Cute furry lambs.

Using a model of a railway carriage (its length, x and time taken to travel, t) the equation for velocity (v = ^x/_t) is derived.  Equating the length of the carriage to wavelength, λ and time to the period, T the...

This Catalyst article looks at X-ray free electron lasers that generate intense beams of X-rays and are used to reveal the structure of complex molecules.
