Growing yeast: plan (non-statutory)
I can plan an investigation to find out about food sources for micro-organisms.
Lesson details
Key learning points
- Yeast is a type of fungus and can be grouped with other fungi including mould, mushrooms and truffles.
- Yeast is living and must get food from the surrounding environment to grow and reproduce.
- Yeast takes in nutrition from food and produces carbon dioxide gas.
- Yeast is a useful micro-organism used in beer and wine making, and baking.
- Scientists control variables during comparative test investigations to see the effect of changing one variable.
Common misconception
Pupils may think yeast is not a living thing because it doesn’t appear to have any of the characteristics of living things when we look at it dry straight from the packet.
Explain that yeast is a type of fungus so it is a living thing in the micro-organisms group. Throughout the lesson, reinforce the characteristics it has that makes it a living thing, such as its ability to grow and reproduce.
