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 demonstrates the uptake and transport of water in plants. Plants take up water and nutrients through tiny tubes running the length of the plant. Using cut flowers and coloured water children investigate the way in which water is transported within plants through the process of transpiration.

These technical briefs focus on low cost approaches to accessing clean water and sanitation. This is vital to health and well being and low costs are particularly important to poorer communities in the developing world.

Technical briefs are documents produced by Practical Action which are freely available to...

A selection of images related to water and sanitation.

Practical Action helps local communities in the developing world gain access to services such as water and sanitation, vital for a decent quality of life. Some examples of how they go about doing this and the technologies involved are demonstrated in these videos:

• Dying for a drink - solar powered...

This Best Evidence Science Teaching topic looks at the key concept of the water cycle. The resource includes diagnostic questions and response activities support students in being able to:

In this STEM activity pupils will perform an experiment to investigate how rain falls from clouds. The activity asks pupils to spray shaving foam on top of a glass of water to create a ‘cloud’, before adding food colouring and watching as the cloud fills up, producing ‘rain’. Pupils will then have the opportunity...

This resource gives a teacher the materials to be able to create a working wall on the topic of water which they can build and add to over a series of lessons.

The idea behind the working wall is that the resources are used to create a display which develops over a period of time as pupils undertake...

Produced by The Centre for Industry Education Collaboration (CIEC), these resources help to put curriculum science in a real life context.

Children follow the use of water from a reservoir, through an industrial site where it is treated, used as cooling water, and treated again before being returned to a...

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...

Water for Everyone Everywhere is a hands-on enquiry based workshop that enables pupils to explore the global issues associated with water access and the role that engineering plays in water distribution.  In the main activity, the general principles of how filters work are explained before a  team activity to build...

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...

Water for the World was developed jointly by Engineers Without Borders UK (EWB) and Arup, a global firm of engineering consultants and specialists. There are three resources, investigating issues of water scarcity, sourcing and supply and showing how engineers can help to solve problems. Although initially designed...
