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...

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.

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 physics extension module from the Salters' Science course focuses on the physics and electronics behind each part of a television set. Production of electron beams and their deflection by electrical or magnetic fields are shown and students see how colours can be...

In this practical activity, from the Institution of Engineering and Technology, students investigate the properties of smart springs and see how they might be used as muscles in a robotic arm. This activity can be used as an extension to the related activity ‘...

This resource looks at the impact of climate change, in particular flooding and drought, and how science can be used to mitigate against it. Students first explore perceptions about climate change, then look at ways to communicate the significance of climate change to different groups of people. They then explore...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). One of the most important questions facing us all is how we will use the planet’s energy resources over the coming decades. Many people believe that wind power can make a vital...

This resource looks at the two main drivers of sea level change - isostasy and eustasy. Each of these terms is explained and a worksheet covers both ideas in three practical demonstrations.

In the first practical, which includes both isostasy and eustasy, students undertake experiments which prove that...
