Circuits

This lesson looks at how circuit symbols can be used to describe a circuit and we practise drawing and interpreting some simple circuit diagrams. We will also start using some models to describe electricity.

Current & series circuits

This lesson describes what electrical current is, how current can be measured and what we find when we measure the current at different points in a series circuit.

Current & parallel circuits

In this lesson we will learn how to recognise and draw parallel circuits and describe how to make and record measurements of current in parallel. We will then describe how current behaves in parallel compared to series

Potential difference

This lesson describes a model to help us understand potential difference, as well as looks at how we can measure potential difference in a series circuit.

Potential difference in parallel circuits

This lesson describes a model to help us understand potential difference, as well as looks at how we can measure potential difference in a parallel circuit.

Resistance

This lesson explores the relationship between current, potential difference and resistance, and we practise using an equation to calculate current, potential difference and resistance

Measuring resistance

This lesson focuses on identifying variables in the measuring resistance practical and how we can appropriately display our results. We will then describe and explain the effect of a length of wire on resistance

Lewis Howard Latimer

This lesson looks at the work of Lewis Howard Latimer and his invention of the carbon filament light bulb. We will also compare different light bulbs and write analytically

Static electricity

This lesson explores static electricity, how objects can become electrically charged and how the charge can produce a force between charged objects.

Magnetic fields

This lesson explores the shape of magnetic fields that can be found around magnets and also the Earth, how field lines can be used to represent a magnetic field.

Magnetic forces

This lesson explores the forces of attraction and repulsion between magnets and how those forces can be explained using magnetic field lines; and how magnetic field lines can be plotted in a simple experiment.

Electromagnets

This lesson describes what an electromagnet is and how an electromagnet can be made. We look at the key variables for an investigation into electromagnets.

Uses of electromagnets

This lesson explores the shape of the magnetic field around an electromagnet and some of the uses of electromagnets.

Unfortunately this lesson is no longer available. Find out why.

Electric motors

This lesson explores how a simple electric motor can be made, and the factors affecting the speed of a direct current motor.
