This video links well to the Scalars and vectors resource.  It explains the difference between speed and velocity in more detail by introducing velocity as the rate of change of displacement (as opposed to distance).

The equation v = ^s/...

This video poses a problem of a spinning tube which has an X and O written on either end.  If the tube is spun from the X end only an X is seen.  Likewise, if the tube is spun from the O end only a O is seen.

A camera is placed underneath a glass table and students asked to predict what would be seen if the...

This video shows how pulling a rope wound around the inner core to the right of a spool creates a torque that must move the spool also to the right.  Whereas doing the same experiment with a toilet roll has the opposite effect.  The roll moves in the opposite direction because the paper is attached to the outside...

Chris Holmes is a sports technologist for sports equipment manufacturer Adidas. This Department for Education clip is useful in showing students how a career such as this relies on a background of STEM study. Chris describes how he specialises in the development of sports balls. His job is to investigate the best...

James and the team at the International Tennis Federation team design equipment to help beginners to pick up the techniques of the game easily. Their work also ensures that Murray, Federer, Nadal and Djokovic all compete fairly and Wimbledon wins are down to talent, not racket-type!

Tomorrow’s Engineers took...

Using a diagram of an open tube an explanation of possible wave patterns is built up.  Firstly, the fundamental mode of vibration is drawn, followed by the second and third harmonics.  For each illustration the number of waves is calculated, i.e, ^λ/₄, ³/₄ λ and ^5...

This video explains how nodes and anti-nodes are formed in standing (stationary) waves.  It shows how the distance between two nodes = ^λ/₂.  A series of standing waves are drawn to show the fundamental wave and its harmonics.  The number of half wavelengths for the fundamental and second,...

This resource, from the Royal Observatory Greenwich, is a beautifully animated video giving a short overview of the life cycle of stars, but crucially how, from Earth, we can observe the different phases of star evolution by plotting all the...

Scratch is widely used in primary schools to teach children basic programming. This resource goes deeper, making use of the familiar Scratch environment to take students deeper into programming concepts such as:

• Algorithm design
• Parallel and sequential instructions
• Event-driven...

This video covers the basics of state changes in water. It explains how the distance between molecules and their motion can be used to explain the three states of water (solid, liquid and gas).  

Contrails occur when water vapour from jet engines condenses – only when the temperature and humidity conditions of the air is right. Contrails act like greenhouse gases. Marc Stettler from Imperial College, London is interested in guiding aircraft to fly where conditions are right, reducing contrail formation....
