This Nuffield Working with Science unit was designed to enable students to trace the way in which the age structure of the population has changed, to gain experience in interpreting and presenting data, to identify and discuss some of the problems of the elderly, and to...

Rockets are used to launch satellites, probes and even astronauts into space. A rocket launch is extremely impressive. Thousands of kilograms are burned in just a few minutes in order to provide the force that the rocket needs in order to overcome the gravity of the Earth. Rockets provide an exciting context to...

Whey is a waste product from the cheese industry. In this experiment students upgrade whey, by converting the lactose into glucose and galactose, or by growing the microorganism K.lactis on agar containing whey.

This Salters’ Chemistry Course unit from the University of York Science Education Group covered:
* The use of fuels in keeping warm
* The chemical changes when fuels burn
* Some consequences of the large scale use of fuels.

A Year 11 module from the Salters’ Key Stage Four double award science course. The breakdown of domestic waste is observed. A text exercises describes the processes used in a waste water plant. Natural cycles, including the carbon cycle and the nitrogen cycle are...

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.

This Nuffield Working with Science unit encouraged students to consider water pollution problems at national and international level, by coming to understand a local example of pollution through their own investigations.

This investigation, produced by Science & Plants for Schools (SAPS), shows how students could investigate the changes in water potential of fruits and vegetables during ripening and storage.

Simple biomechanical...

This Nuffield Working with Science unit is substantially out of date but can suggest approaches for tackling related issues now. The intention was that students should become aware of the real problems of providing sufficient potable water for all our needs by the year...

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...

This activity looks at water consumption on a local and global scale. Students learn about the main water contaminants and various methods of purification and the role of engineers and their approach to design challenges. The resource aims to inspire an interest in water conservation and to introduce students to...

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...

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...

This Nuffield Working with Science unit was designed to help students to appreciate why the study of weather is important. The topic was planned to cover factors that influence the weather and the reasons why weather forecasters need to collect a large amount of...
