Key learning points

1. A cell is a single unit that is needed for electricity to flow around a circuit and a battery is a group of cells.
2. The V on a cell stands for volts, and is a measure of the size of electrical push it provides to a circuit.
3. Cells or batteries with a higher voltage provide a stronger electrical push to a circuit.
4. Adding more cells produces a higher voltage and a stronger electrical push to a circuit.
5. Scientists plan different types of enquiries to find answers to questions.
