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...

• This annual competition is run by the National Physical Laboratory and challenges students to launch a rocket powered by water or air pressure and see how long they can keep it in the air, whilst trying to earn additional bonus seconds by landing it in designated...

Act 1

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

This activity sheet builds on students' knowledge of separating mixtures and looks at how and why water is treated.  There is also an extension activity which looks at the importance of oxygenation of lake water.

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 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.

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...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Recognise that as a transverse wave travels forward, the medium through which it travels does not.
• Describe the movement of each ‘particle’ of a transverse wave as the wave moves...

This resource from Defence Dynamics looks at waves and the electromagnetic spectrum. The resources are split into two student activity sheets.

The ...

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...
