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...

London sewage treatment was developed to protect Londoners from water borne disease. Now the Thames Tideway tunnel is being built to help the sewage system cope with the rising London population. This lesson will allow students to conduct experimental work to model water treatment and have a chance to consider the...

This activity focuses on the link between water usage at home and the number of people living in their household, as well as comparing the water usage within the UK to that of other countries.

Students estimate how...

This activity focuses on the link between the UK’s current water usage and the predicted increase expected in the future. Looking at a water board website, students think about how the website is set up and the formulae that are being used. They then work in groups to...

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...

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...

The loose fragments of material on the Moon’s surface are called regolith. This regolith, a product of bombardment by meteorites, is the debris thrown out of the impact craters. By contrast, regolith on Earth (called ‘soil’ as it contains organic material) is a product of weathering. ‘Weathering’ describes all the...

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 challenge is an opportunity for students to explore, experiment and innovate whilst designing a specialised wetsuit for paratriathletes who need specialised equipment to allow them to compete. Whilst the development in technology of prosthetic limbs, racing wheelchairs and handcycles has been substantial, no...

This activity, from the Institution of Engineering and technology (IET), asks students to investigate a simple piezoelectric device. The engineers behind the Watt Nightclub in Rotterdam investigated the use of the piezoelectric effect to turn the energy created by...

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

This topic, from the Association for Science Education (ASE), focuses on nutrition and looks at links between diet and health. Students are able to reflect on the nutritional and social values of different diets and then exchange information about their findings. As they work though the topic the students make a...
