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 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 ‘...
