Room 14 have decided to test the amount of germs and bacteria that are around us and our classroom. There is a lot of sickness around at the moment and it is important we all wash our hands to rid the germs and stop them from spreading. We got into 6 groups, each group had a different thing to test with their piece of bread.
Group 1 -Washed their hands really well before touching the bread.
Group 2 - Didn't wash their hands then touched the bread.
Group 3 - Wiped their bread over the carpet.
Group 4 - Coughed all over their piece of bread.
Group 5 - Wiped their bread over the tables.
Group 6 - Picked their nose and wiped it on the bread. (ew!!)
We made predictions on what we think will happen.
We will observe all 6 test groups and record the changes that occur in 2 weeks.
Which one will have the most germs?
Why have these changes happened?
What makes germs spread?
How can we reduce germ growth in our classroom?
