A topical new series that addresses the pros and cons of all energy courses. Each book looks at the fundamentals of each energy type with information on how they work, their benefits and limits, examples from around...

Energy use is one of the most important issues of our age. This series looks at different sources of power that are in use today.

Water Power: the Micro-Hydro Revolution

This Catalyst article is about a micro-hydroelectric power station on a river in Yorkshire. As oil prices soar and global warming threatens, the need for affordable green solutions to the energy crisis is ever increasing. Giant hydroelectric power stations, such as the Three Gorges Dam in China, will help to fulfil...

Water pressure at work in London

In this lesson students look at the related concepts of pressure and force (pressure = Force/ Area), units used, measurement and how a large force can result from pressure acting over a given area. They will move from calculating the weight (under gravity) of a column of water or air to the pressure of this as...

Water Quality

In this activity students consider the questions:

• How can the purity of swimming water be tested?
• What exactly is the Blue Flag award?
• How reliable are the measurements and the criteria for the Blue Flag award?
• What is the status of the quality of fresh and salt water for swimming...

Water resources

These fact sheets for primary aged pupils explore the how fresh water is needed for every part of our lives, and how access to clean water is becoming increasingly difficult with a growing population and changing climate so discovering new supplies and managing water carefully is more important than ever.

Water resources

These fact sheets for secondary aged pupils explore hard and soft water and an activity to test for hard water. They also look at how fresh water is needed for every part of our lives, and how access to clean water is becoming increasingly difficult with a growing population and changing climate so discovering new...

Water rocket challenge

• This annual competition is run by the National Physical Laboratory and challenges students to launch a rocket powered by water or air pressure and see how long they can keep it in the air, whilst trying to earn additional bonus seconds by landing it in designated...

Water Rockets

From the Centre for Science Education, and with support from Shell Education services, these materials help children to investigate forces and motion.

Water rockets can be made using plastic bottles and these are propelled by pressurised water. The rockets need to be launched in a suitable open area such as...

Water Shortage

In this activity students consider the questions:

• What are the main sources that cause severe water shortage in Europe?
• How different harmful elements (e.g. fertilizers, gasoline, sulphuric acid) pollute freshwater?
• What methods / strategies can be used to save water?
• What methods...
