In Year 2, the children had a few investigations to implement. The children had to investigate the following questions: Does washing our hands get rid of all the germs? Does doing more sports help you run faster? Does brushing your teeth get rid of all the plaque? The children placed washed hands and unwashed hands in agar jelly overnight and left it overnight. Then they had to count the spores that had developed in the morning. There was a race between children who did sports and those that did not to see who ran the fastest. In addition to that, the children used special tablets that show plaque on the teeth and brushed their teeth to see if they could get rid of the plaque.
