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 resource from the IET Faraday programme, supported by MEI and Tomorrow's Engineers, provides students the opportunity to explore the volume of water that passes through aqueducts.

This video introduces Nariba, a graduate water engineer for engineering company Halcrow. Nariba performs assessments for construction projects, focusing on flood risk management. Her work...

This resource is part of a collection of Nuffield Maths resources exploring Algebra. The demand is roughly equivalent to that in GCE A level.

Here, students use linear and quadratic functions to model water flow data and calculate percentage errors.

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 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...

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...

A video is shown of an octagonal water tank being...

A measuring cylinder is shown with divisions marked in millilitres. Water is poured at a constant rate into the cylinder. The challenge is to graph the volume of water against time. The resulting graph is linear.

This resource from the IET Faraday programme, supported by MEI and Tomorrow's Engineers, looks at the trigonometry and scale drawing involved in the construction of water wheels.

"A water wheel is a machine for converting the energy of flowing or falling water into useful forms of...
