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...

A Catalyst article about the UK's extremely reliable electricity supply system generated in power stations which burn gas or coal, or use nuclear fuel. The article looks at how this is achieved using high voltages and how the demands for power at different times of the day and year are met.

This article is...

This resource from the Institute of Physics, describes how electrocardiagrams (ECGs) record the activity of the heart through electrodes placed on a patient's skin. The teacher's notes contain an introduction to ECGs and lesson notes for the associated PowerPoint file. A mark scheme for the worksheet is also...

From Solar Spark, this practical activity explores the reactions at electrodes in an electrical circuit. A solar cell contains two electrodes. Different reactions happen at each electrode so that electrons can move around the circuit to give an electric current. In this experiment students use filter paper soaked...

This resource provides a lesson plan showing how to use drama to teach about electrolysis. The approach used in the lesson is based on education research which is summarised in a separate research summary document.

The lesson outlines a sequence of activities and key questions to ask to help pupils...

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

• Describe the process of electrolysis in terms of chemical reactions occurring at the electrodes.
• Identify the cathode (or anode) in a diagram of the electrolysis of a solution of...

This video demonstrates an experiment to investigate how current affects the strength of a magnetic field. The Phyphox app on a mobile phone is used to measure the magnetic field strength. The second part explains how to plot a graph to evaluate the relationship between current and magnetic field strength. 

This series of activities from NASA take a mathematical approach to looking at electromagnetic radiation. They are intended as supplementary problems for students looking for additional challenges in mathematics and physical science from age 11 to 19 years. The problems were created to be authentic glimpses of...

Produced by StoryCog, this video demonstrates the process of electromagnetic induction. The video shows a simple piece of equipment that can readily be made which contains spinning magnets, a wire coil and a lamp. Spinning the magnets past the coil produces an electric current and lights the lamp.

This activity, from the Institution of Engineering and Technology (IET), is one of a series of activities which explores body centric communications. Students study data and annotate a diagram to show what electromagnetic radiation can penetrate the atmosphere. The...

• Identify types of electromagnetic radiation that can be naturally occurring.
• Describe a range of sources of harmful electromagnetic...

This poster shows how the electromagnetic spectrum has been divided into seven ‘types’ according to use, with a look at how the National Physical Laboratory (NPL) uses it in high precision measurement.
