Last week, Year 2 carried out an experiment to test hygiene and germs. We used potatoes to test germs on different surfaces.
Potato 1: Control potato
Potato 2: Our hands
Potato 3: The floor
Potato 4: The toilet
We looked at the potatoes a week later, after they had been kept in the cupboard.
We investigated together, observing and describing the changes. This included how they look, feel and smell.
