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...

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...

These resources from the Institution of Engineering and Technology, produced in association with Fairfield Control Systems, explore the theme of waterways.

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...

In the simulation students can watch a string vibrate in slow motion. You can wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. The simulation also allows you to adjust the damping and tension.

Sample learning outcomes include:

*Discuss wave...

Does light behave like a wave, a stream of particles or both? Scientists at the University of Oxford are taking advantage of the particle-wave duality of light to carry out work developing exciting new technologies.

The speed of a wave in a solid is investigated in this video. A signal generator and length of elastic are used to measure the frequency and wavelength of a wave, which allows wave speed to be calculated. 

A ripple tank is used in this video to calculate the speed of a water wave by measuring the distance and time. This is a GCSE Combined Science and Physics Required Practical.
