Hand washing experiment

We wanted to find out what was the best way to get rid of germs so we tried
  •  cold water
  • warm water  
  • warm water and soap

Cold water was not very good and lots of germs stayed on our hands.

Warm water didn't seem to work very well either so we tried warm water and soap

Soap turned the water a milky colour and it removed lots of the germs.

Can you see the germs in the bowl?

We washed our hands really well but some of us still had some germs on them. Some of us even had germs on our faces!

How do you think they got there?

We had a really good time learning about the importance of keeping clean and washing hands with warm water and soap.
