Aimed at Key Stage Two, this resource looks at the problem of launching RNLI lifeboats from different types of terrain in all kinds of weather. Linked to work on forces, shape and space and design and technology, it introduces the concept that both force and area affect the pressure applied on a surface. Working...

Some of the biggest challenges we face stem from how we interact with our environment, and engineering is essential to finding sustainable solutions. From renewable power to recycling, to making our homes more energy efficient, and tackling how we feed a growing population, engineering is a vital field.

Some of the biggest challenges we face stem from how we interact with our environment, and engineering is at the heart of finding sustainable solutions. Working with water is particularly important when thinking about the environment because water sustains all life and is essential to the survival of the planet....

In this practical activity, students investigate the salinity of three different water samples using a multimeter. Students first calibrate their salination probe and test the salinity of their solutions. Students can be asked to suggest how errors might have appeared...

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...

This physics extension module from the Salters' Science course focuses on the physics and electronics behind each part of a television set. Production of electron beams and their deflection by electrical or magnetic fields are shown and students see how colours can be...

In this practical activity, from the Institution of Engineering and Technology, students investigate the properties of smart springs and see how they might be used as muscles in a robotic arm. This activity can be used as an extension to the related activity ‘...

A CREST investigation produced by Practical Action, in collaboration with the British Science Association, for primary pupils. 

Students find out  how farmers in Bangladesh can earn more money for their family by turning milk into yoghurt.  They go on to make a range of different flavoured yoghurts...
