This physics extension module from the Salters' Science course deals with binary digital electronic devices, taking a systems approach. Ideas of input, output and control are considered and the concept of feedback. The use of logic gates to control switches and latches...

The materials provide teachers with examples of different enquiry types, e.g. classifying and identifying, developing systems, and pattern seeking.  The booklet provides an overview of the enquiries and the particular approaches used. Scientists use many different ways to collect evidence, but a survey undertaken...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). Building materials and construction methods provide an interesting context in which students can develop their understanding of basic ideas...

A Year Ten module from the Salters’ double award science course. Exercises on codes and signalling methods introduce ideas about communication. A study of the ear leads to sound communication systems such as radio and telephones. Lenses are studied and the formation of...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). It is based on two specially developed resources produced by SEP: the Optical Signal Transmission Set and the Analogue/Digital Transmission...

A Year Ten module from the Salters double award science course. Models are used to illustrate conservation of current in a series circuit leading to studies of voltage, current and resistance and the resistance law. Devices which have different resistance in response to...

Produced by the Hamilton Trust, this resource aimed at Year Six gives details of six lessons on balanced forces. Children learn about gravity, air resistance, friction and upthrust of liquids. Working scientifically they investigate what happens when an elastic band stretches under force and develop an...

A Year Ten module from the Salters’ double award science course. The module begins by looking at the large variety of labour-saving devices now available and their impact on life-styles. Students work with a range of common electrical devices to investigate the relative...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). An important part of understanding energy is getting to know the different ways it can be stored and transferred. Finding ways to do this with...

A Year 11 module from the Salters’ Key Stage Four double award science course. This module deals with the generation, transmission and supply of electric power.

Understanding of the inductive effect is developed...

This series of activities, from the Institute of Physics, help student to understand electrical resistance. What is resistance, how it can be measured, how it arises and what affects it? During the topic, resistance is related to current, voltage, type of material, temperature and light intensity. The electrical...

In this learning episode, from the Institute of Physics, students derive the equation relating electromotive force (emf), terminal potential difference, current and internal resistance. They then tackle questions about the internal resistance of a power supply.

Produced by the Institute of Physics, this learning episode helps students to distinguish alternating from direct currents before revising why alternating current (ac) is so important.

The range of activities include...

In this learning episode from the Institute of Physics, students are introduced to capacitors. Through practical investigations, students look at their charge and discharge process.

The activities include:
•...

This learning episode, from the Institute of Physics, helps students understand how capacitors charge and the concept of capacitance. Students investigate the relationship between charge and potential difference across a capacitor.
