Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- A cell is a single unit that is needed for electricity to flow around a circuit and a battery is a group of cells.
- The V on a cell stands for volts, and is a measure of the size of electrical push it provides to a circuit.
- Cells or batteries with a higher voltage provide a stronger electrical push to a circuit.
- Adding more cells produces a higher voltage and a stronger electrical push to a circuit.
- Scientists plan different types of enquiries to find answers to questions.
Keywords
Cell - A cell is a single unit that is needed for electricity to flow around a circuit.
Battery - A battery is two or more cells working together.
Voltage - Voltage is a measure of the size of the push provided by a cell or other source of electricity.
Affect - To affect something or someone is to change it or how it behaves.
Brightness - The brightness of a lamp is the amount of light it gives out.
Common misconception
The voltage of a cell is proportional to the size of the cell. Voltage is a tangible substance rather than a measure of electrical “push”.
Teaching slides and CfUs will clarify that voltage is a measure of the size of the push provided by a cell or other source of electricity, and that cell size is not proportional to voltage.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
