In Science, we have been investigating what makes mould grow.
Each pair could choose their independent variables, to determine what might cause a change in our dependent variable (the amount of mould on a slice of bread). Different investigations took place into the amount of moisture, light and heat provided. We also had a couple of investigations into whether being surrounded by bacteria and other dirt encouraged mould growth, and one particularly disgusting example involving rabbit poo!
Children had to ensure a fair test, by identifying the control variables, and explaining how they were sure their test conditions were controlled.
As you can see in the photos below, we had varying results!
