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 creates a higher voltage and a stronger electrical push to a circuit.
Scientists plan different types of enquiries to find answers to questions.

Common misconception

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.

Keywords

Cell - A cell is a single unit that is needed for electricity to flow around a circuit.
Battery - When there are two or more cells working together, we call it a battery.
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 change how it behaves.
Brightness - The brightness of a bulb is the amount of light it produces.
