A good A-level physics revision video linked to adding vectors.  Here you look at how this can be done both mathematically or using scale drawings, by being taken through each method step by step.  This is ideal for revision and could be used in a lesson or shared with students.

Steve analyses the flow of air over racing cars.  He studied aero-mechanical engineering at university and following a two week summer placement, at Lola cars, he was offered a position in the company.

This Catalyst article investigates the nature of aerogels, which are among the least dense solid materials, not much denser than air. Aerogels were made as the result of a bet and ended up going into space to capture comet dust. They are the lightest solids which exist and have some unusual features.

The...

These technical briefs look at agricultural production in many parts of the world, carried out on a small-scale by farmers. Relatively small improvements in agricultural practice can have a big impact on yield and dramatically improve the life of a farmer and their family.

Technical briefs are documents...

Alice and Bob in Wonderland are animations produced by the Perimeter Institute for Theoretical Physics. They are based around the questions that Alice has about the physical world and how these can lead to "powerful ideas" in physics, such as energy-mass equivalence and relativity. Topics include time travel, the...

Produced by the Royal Observatory Greenwich, this booklet gives instructions on a practical demonstration of the Doppler effect. The practical uses a portable speaker an audio software to calculate the change in frequency. Included is an online video that shows the demonstration and places it in the context of...

This Catalyst article investigates materials used in jet engines. They must withstand high temperatures and great forces. Special alloys are used for structures such as turbine blades. The article is from Catalyst:...

Produced by the Learning and Skills Improvement Service, these materials introduce students to circuit symbols. They develop their knowledge and understanding of circuit symbols and components through a range of short, interactive learning activities. These are particularly useful to reinforce, or consolidate,...

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 poster looks at the nature of antimatter. One side of the poster discusses Dirac’s prediction and the subsequent discovery of antimatter, in the form of the positron. The difficulty of the storage of antimatter is explained and the use of positrons in medical imaging (PET scanners) is described. The other side...

This Catalyst article investigates whether airships are making a comeback. The Airlander is an airship which can be used for transporting heavy loads over long distances.

The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 3.
