Common misconception
Pupils may not consider mould to be a living thing because it does not move in the ways we are familiar with animals moving.
Remind pupils that all living things grow, reproduce and move, and that mould can do all of these things. It is a type of fungus. Which is a living thing that is part of the micro-organisms group.
Equipment
