Composites: Designing Materials for the Future

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). Composites are made by physically combining two or more materials. Many composite materials are used to provide strength and rigidity while using thinner, lighter components. However, they...

Invention of Nylon

This film, from Twig World, looks at what makes the polymer Nylon so durable. The key points made in the film are: •In the past, clothes were all made from natural sources, such as silk, wool and cotton. •Then Wallace Carothers discovered nylon in 1939. •It was discovered through experimentation with polymers,...

Metals and Smart Alloys

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP).

Metals have been used for many thousands of years, but it was only in the 20th century that an understanding developed of how their properties could be explained in terms of their...

Tim Peake public presentation

This presentation was produced by the UK Space Agency for Tim Peake's mission to the International Space Station in 2015/16.

Printing in Three Dimensions

This Catalyst article looks at 3D printing, a new technology which is rapidly finding applications. Although probably too slow for mass production it is useful for producing prototypes and tailor-made items. In a 3D printer, layers of polymer beads are printed one on top of the other. Heat melts the polymer beads...

Freaky Hand

This video from the Royal Society of Chemistry (RSC), aimed at primary teachers, demonstrates an experiment which may be used when learning about irreversible reactions. Vinegar is poured into a jar and a plastic glove containing bicarbonate of soda is fitted...

Evaporation

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

  • Recognise that evaporation occurs in different liquids, not just water.
  • Predict that evaporation will occur in liquids with a temperature that is less than or greater than that of...

Exothermic and endothermic reactions

 

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

  • Recognise that energy is conserved during an exothermic reaction.
  • Describe how the temperature of the chemicals will change with time after an exothermic reaction.
  • ...
