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:

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...

This Catalyst article describes how the salty water in the oceans has some consequences for how the ocean water mixes – or does not mix. There are distinct bodies of water in the oceans which mix only very slowly. The experiments detailed in the article will explain why this is.

The article is from Catalyst...

In this resource from the European Space Agency, students design and develop an entire space mission to Mars. The objective of the mission is to send a programmed LEGO rover to the surface of the Red Planet to study changes in state of water. Students take temperature measurements and interpret the data collected...

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...

In this set of three activities, pupils will spend a day recording how much water a person uses in an average day, followed by an experimental activity where they will use ‘lunar ice cores’ and filter them to get water. Through these activities, pupils will learn how a filtration system can be used to separate...
