This afternoon in Science, we looked at our bread samples which we collected before Easter to see if we could answer our question:

How does the amount of light affect the amount of bacteria grown on a piece of bread?

Our bread samples showed that the amount of light does affect the amount of bacteria grown on a piece of bread. The bread which was in direct light had the least amount of bacteria growing whereas the bread which had been in complete darkness had the most amount. We learnt that this is because light can sometimes kill some types of bacteria, preventing it from growing which means means that the darkness allowed more diverse species of bacteria to survive.

This then lead onto a further conversation about light and how we could investigate how different types of light sources could affect the amount of bacteria grown. Would a heat lamp produce different results to a different type of lamp?

The children concluded their findings in their science book by explaining what our results showed.

Well done Year6, some great scientific thinking this afternoon!
