Carom Maths provides this resource for teachers and students of A Level mathematics.

This presentation shows how, when placing triominoes onto a chessboard, there is always one empty square. An algebraic proof is developed to show that the empty square will always appear in the same location, or in one of...

Published in August 2014, this is the final report of the three-year evaluation of the Triple Science Support Programme (TSSP) and the two year evaluation of Triple Science Networks (TSN).

The full collection of STEM Learning impact and evaluation research reports can be viewed...

This Catalyst article looks at peatlands which usually conjures up images of bleak, boggy hillsides across Northern Europe, Russia and the USA. But peatlands are also found in the tropics. These currently act as a significant store of carbon, yet these valuable ecosystems are under threat; their disappearance could...

This poster illustrates how expertise from designers, engineers and technologists is used to design and manufacture an innovative snowboard. It helps to illustrate how STEM industries offer many exciting career opportunities.

In this Catalyst article an experiment is described in which the formation of clouds can be replicated. The experiment requires nothing more than a plastic bottle, warm water, matches and a small thermometer.

This Catalyst article investigates how honeycomb (cinder toffee) is made using a thermal decomposition reaction to produce the gas bubbles. Sodium hydrogen carbonate (also known as sodium bicarbonate or bicarbonate of soda) has the chemical formula NaHCO3. When it is heated above about 80°C it begins to break down...

This Catalyst article presents an activity in chromatography, which can be used to separate the different dyes used in coloured inks.

Two animations, from the Wellcome Trust, illustrate the life cycle of the trypanosomiasis protozoan parasite. They illustrate the journey of these single celled parasites, which cause human African trypanosomiasis or sleeping sickness, from the gut of the tsetse fly...

From the Wellcome Trust, this animation shows how the human immune system attempts to contain a tuberculosis infection and how the bacteria are transmitted to new people.

Tuberculosis usually affects the respiratory...

With an increase in tuberculosis (TB) throughout the world during the 21st century, this resource looks at what scientists are doing to combat a disease that many believed was a problem of the past.

The TB fact file describes the disease, its symptoms and incidence and reviews current research into its cause...

This STEMNET resource describes the background and career of tunnel design engineer and STEM Ambassador Kate Woolley.

Kate designs and supervises the construction of tunnels and finds that she needs to use maths, physics and technology to make everyday decisions. Engineering, however, had not always seemed a...

Tunnelworks is a series of teaching and learning resources linking mathematics and science to the Thames Tideway Tunnel project, a major new sewer that will help protect the River Thames from increasing pollution. Background to the project is given in the...
