This afternoon we were investigating germs. We discovered that germs are so small that we can not see them without a microscope. However, they can cause all sorts, of problems including making us sick.
We made germ models using playdough. These models show how germs have a rough surface and can cling onto things, making it harder to get rid of them.
We also covered our hands in flour and dusted them off. This showed that some of the flour was still in between our fingers and the wrinkles in our hands. Just like germs the flour found a hiding place!
Next we made sure that we washed our hands carefully with soap and water. We made sure that we cleaned the back and front of our hands and in between our fingers too.
