If there is life elsewhere in our solar system it’s likely to live in a pretty cold environment. In this resource, students investigate the effect of antifreeze on the freezing point of water and how it can allow fragile cells to survive extreme cold. In the video, Judith Green explains how students can plan an...

This activity, produced by Solar Spark, uses "magic dye", a mixture of three different dye molecules. The mixture contains a yellow disperse dye, a direct blue dye and an acid red dye. When a fabric is put into the mixture, the dyes only attach to the types of fabrics they can bond well with. For example, the blue...

This Catalyst article describes how to make ice cream using a mixture of ice and salt, without the need of a freezer. Detailed instructions and an explanation of how it works is included, as well as a link to a video showing how the process can be sped up using liquid nitrogen.

This resource looks at how cutting edge science is being used to answer archaeological questions, as well as solving present day problems, such as the identification of meat in processed foods. Analysis of mitochondrial DNA was performed, at the University of York, on samples from skeletal remains unearthed by the...

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...

This activity is provided by ASE and describes a novel way to conduct a number of chemistry experiments on a small scale with clearly visible results and needing a minimum of equipment.

The resource contains...

This revised Nuffield Chemistry option began with everyday plastics and sought to demonstrate, measure and explain their properties. Thermoplastics were distinguished from thermosets and the differences explained in terms of the structure and bonding of polymers. A historical section showed how natural materials...
