Class 2 – Washing your hands investigation

A couple of weeks ago Class 2 began an investigations to find out why it is so important to wash your hands.

We used three pieces of bread. The first piece we all touched after being out on the playground at playtime (without washing our hands). The second piece we all touched after a normal classroom lesson (without washing our hands). The final piece of bread we all touched after washing our hands with soap and using hand sanitiser.

Once we had touched all three we put them in separate zip lock bags and hung them in the same place in the corridor so that the other classes could also watch what happens. Today after two weeks we wrote our conclusions.

This was the first piece of bread we touched after being on the playground!
This is the piece we touched after a lesson.
This piece of bread we touched after washing and sanitising our hands.

“We found out that germs will make mould on bread because there is thousands of germs on the bread. The first piece of bread was after playtime and had the most germs on it. The second piece was after a lesson. It had the second most germs on it. The last piece of bread was after cleaning our hands and it was spotless! We should wash our hands because it gets rid of 99.9 percent of germs!”

“We found out that when we put germs on bread it makes mould. You should wash your hands to get rid of germs”

Zachary Morgan

“The germs made the mould which is the green stuff on the bread. We should wash our hands so we don’t get poorly. We should wash our hands to kill most of the germs, It was really fun”

Beau McArdle

“We found out that the more germs you get the more bits of mould there is. Germs can make you poorly. Some germs can be good for you and some are bad. Germs make mould. The whole investigation was about why we wash our hands. We wash our hands so that we don’t get poorly”
