Hannah Fry: Algebra

In this video, from Head Steam, Hannah Fry gives an overview of the power of algebra. She explains how the same formula can be applied in a variety of situations and gives an introduction as to why it is important that students are able to understand and use algebra. There are a variety of examples of where...

Hannah Fry: Zombies

In this short video, Hannah Fry uses mathematics to show that there is no need to be afraid of zombies as there is plenty of time to get out of the way. Hannah begins by making some basic assumptions and models the situation mathematically using powers of 2 and explains how things that grow exponentially grow...

Head STEAM, produced by TV and online production company 360Production, is an educational channel that aims to inspire students to become a future leader of STEAM (Science, Technology, Engineering, Arts and Maths) industries. The short videos explore a variety of STEAM topics such as sound waves and frequencies, 3D...

Jheni Osman: Bridges

Einstein’s special theory of relativity helped to design the world’s tallest bridge. The bridge is taller than the Eiffel Tower and can carry 35,000 tonnes. All bridges have to cope with two main forces, tension and compression.

Engineers also had to consider the problem of accuracy when working on such...

Jheni Osman: Trees

In this film Jheni Osman describes how the transport systems in plants, the xylem and phloem, may limit the height to which trees can grow. Transpiration is driven by evaporation from the leaves, pulling water up through the xylem. The taller the tree, the further the water has to move against gravity.

Jon Chase: Cake in a Mug

This film, from Headsteam, shows how to make a cake in a cup. The presenter explains how gluten helps to form the structure of the cake. The eggs help to keep the cake moist, and to provide structure when they denature.

Martin Archer: Beat Matching

This film explains how the pitch of a sound is related to its frequency. However, motion can also change the apparent frequency of a sound and this is known as the Doppler Effect. Animations illustrate the Doppler effect and also how redshift is used to calculate whether a star is moving towards us or away.

Martin Archer: Viruses

This film looks at what a virus is. Martin Archer loves a comic book movie, especially the villains, but he has five reasons why viruses are the ultimate bad guys. Animations and film clips illustrate the structure of a virus, the process of infection and dormancy.

Smartphone Science

This film, from Headsteam, explains how an accelerometer works in a mobile phone. Accelerometers measure the rate of change of velocity. Newton’s second law states that the overall force on an object is equal to the mass of that object multiplied by the acceleration of the object, and smart phones use this to...
