Sneezesafe Update!

It has been almost 3 weeks since we started our Sneezesafe experiment with our buddies in Room 7.

Yesterday, our buddies came to see us to find out what had happened to the bread.  We began by reminding ourselves of the video we had watched and what was the best way to stop germs spreading.  Then we looked at out slices of bread.  It took almost 2 weeks before the bread started showing signs of germs, much longer than we thought, but most likely due to the fact that the slices of bread were all in sealed bags.

First we revealed the bread that hadn't been touched...

No obvious difference from when it was put in the bag!

Next we revealed the bread that was touched by Brianna in Room 7 after she washed her hands...

 Small areas of mould growing on one edge of the bread.

Finally we revealed the bread that everyone in the class touched.  This was the one the students predicted would grow the most mould, though I'm not sure they expected this!

 

The bread is blue, green, yellow and even black in places!

Mrs Buchanan has reported that all her class are now coughing and sneezing into tissues and elbows, so fingers crossed they'll be less illnesses this winter!
