This chemistry extension module of the Salters' Science course revises and extends students’ ideas about the structure and properties of water. It deals with hardness of water, the action of soap and other detergents and properties of emulsions.

In this activity, students take the role of data analysts of the World Water Resources Board (WWRB) a fictional organisation charged with providing financial aid to countries most in need of water. They will compare the availability of water in Algeria, Jordan and Turkey. Students will determine how to fairly...

This resource pack can be used to highlight issues such as global water scarcity, the challenges people face when sourcing water and maintaining a water supply in developing countries and the role of the engineers in solving these problems. Following a quick quiz, a presentation introduces the scale of local and...

In this practical activity, students investigate the salinity of three different water samples using a multimeter. Students first calibrate their salination probe and test the salinity of their solutions. Students can be asked to suggest how errors might have appeared...

Water for Everyone Everywhere is a workshop designed to encourage pupils to explore the global challenges associated with access to safe and clean drinking water around the world. Pupils learn about the importance of water to people’s everyday lives and the role that engineering infrastructure plays in the...

The spacecraft that have orbited around Mars and landed on its surface have shown us (via images and data) that there is no liquid water on the surface of Mars. However, these satellite images have also revealed to us features that appear to have been created or carved out by flowing water. In fact, scientists feel...

Scientists must design and evaluate many ways of extracting water from the lunar permafrost before planning lunar colonies and manned missions using the moon as a base.

In this activity students will construct a solar water collector. Using the collector, students will collect and calculate the amount of...

This resource, from Siemens UK, encourages students to appreciate the importance of clean water and the problems that may arise in the absence of it. Students consider soluble and insoluble pollutants and methods of filtration. They then explore contamination by microorganisms, water-borne diseases and the...

Does light behave like a wave, a stream of particles or both? Scientists at the University of Oxford are taking advantage of the particle-wave duality of light to carry out work developing exciting new technologies.

This physics extension module from the Salters’ Science course covers the action of sensors and amplifiers in electronic systems. Potential dividers are studied as a way of supplying different voltages. The action of light dependent resistors and thermistors in...

Work done in this Nuffield 13 - 16 module followed from the S unit called ‘Cars on the move’. This X unit provided enough material for eight double periods. It could be selected to complete either a Science or a Further Science course. The teachers’ guide included seven...

Produced by the Wellcome Trust, these resources include an interactive evolutionary tree and a video of the Tree of Life. These materials will help students to find out more about the work of Charles Darwin and evolution. The resources contain:

Tree of life video: The video is a short...

This short activity introduces students to the ideas of the footprint and resolution of an image, asking them to choose and use appropriate methods to calculate how these quantities would change as they moved a camera to a series of vantage points above the surface of the Earth

Work done in this Nuffield 13 - 16 module followed from the unit called ‘Food and digestion’. This B unit provided enough material for six double periods in the third year of secondary school (year nine). The teachers’ guide included four worksheets to supplement the...

This activity uses a humorous video to raise a serious question: can science tell us what animals are saying, and interpret their emotions? The Bow-lingual dog translator claims to detect animal emotions by analysing bark sounds waves. Students use research evidence to decide whether the device does what it claims...
