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.
Keywords
Fungi - Fungi are a type of micro-organism that feed on organic matter.
Yeast - Yeast is a type of fungus. It is a micro-organism used for making bread.
Carbon dioxide - Carbon dioxide is a type of gas.
Comparative test - In a comparative test, the thing that is being changed has labels, such as the types of materials.
Variables - A variable is something that can be changed, measured or kept the same in an investigation.
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.
Equipment
Teachers may wish to have ready a set of equipment children could possibly use for carrying out their yeast investigation in Lesson 10 to help them make decisions about what they might need.
