As part of our Living Things unit, Year 6 have been looking at microorganisms. This week our scientific questions was: Is yeast a living thing? We looked at the processes that living things do using the mnemonic MRS GREN. The children then completed a Science investigation to answer the question.

First they added yeast to warm water. The yeast then needed nutrition which was in the form of sugar. Attaching the balloon to the top of the bottle would show whether yeast respires and/or excretes if it inflated.

The children determined that yeast was in fact a living thing.
