Electrochemical Writing
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...

Electroluminescent Wire
This short film from the Technology Enhancement Programme (TEP) is one of a series of clips which were produced to demonstrate the properties and use of a range of smart materials.
Electroluminescent (EL) wire is a thin, flexible wire that glows brightly when an alternating current is passed through it. It...
Electrolysis - R2P
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...
Electrolysis of solutions
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...
Electromagnet investigation and results
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.
...Electromagnetic induction
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.
