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...

CK's job is helping people under the impact of the conflict ongoing in Yemen. In Yemen, he is managing a water and sewer programme which requires lots of engineering skill and also project management skill.

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...

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 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 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...

A Catalyst article looking at renewable energy. To tackle climate change and all the challenges imposed by the need to find alternative and reliable energy sources, there is one major resource that has remained untapped until now: wave power. This article describes the size of this resource and presents the leading...

Due to problems in the manufacture of tinplate coils, the edge of the strip can be slightly longer than the centre. This causes a 'wave' on the wall of the coil but can be rectified by differentially stretching the strip to make the edges flat. Students are required to apply Pythagoras' theorem to find the radius...

The We Are Aliens! teaching resources were produced to support the planetarium show made by NSC Creative. They have been produced by lead educators from the National Space Academy to use the context of space to teach physics, chemistry and biology in the curriculum. The resources contain practical activities,...

This Catalyst article investigates how polymer materials can be designed and printed with electrical properties that allow them to be used in wearable electronic devices. The article is from Catalyst: Secondary Science...

This activity demonstrates how a Raspberry Pi running Python can interact with other devices in the browser. Using the web.py framework, web forms can be served to mobile phones, tablets etc, and accept input which is fed into the Python script. The project helps students to see how web servers work, and how...

The Wellcome Trust Monitor is a unique survey of UK adults' and young people's views of science, biomedical research and science education.

* Wave 1 (the baseline survey) was conducted in 2009 by the National Centre for Social Research who interviewed 1,179 adults and 374 young people.
*Wave 2 was...

From the Wellcome Trust, these short animations can be downloaded and used in the classroom. The animations help students to understand a range of biological processes and diseases. These include:
* The genome, methods used in DNA sequencing and the translation and transcription of DNA into proteins
*...
