Food Microbes Experiment

In science, over the last week, we have been looking at the effects of microbes. We decided to set up an experiment where we put three similar slices of bread into plastice bags and placed them in different conditions. Sample A was placed by a window where it would encounter heat and light, Sample B in a box where it would have heat, but not light and Sample C in a fridge. Today we looked at the results.

The children concluded that microbes need heat to multiply quickly. In cold conditions the microbes are slowed down and the mould grows more slowly. This is why we freeze food to keep it fresh.
