What did we grow??
This week we set out to find the grossiest place in the Arboretum. The Home Schoolers were given swabs and told to pick a place they thought were full of germs and bacteria. Some of the places they swabbed included bathroom sink handles, trash bins, bottom of shoes, front desk keyboard and, of course, the toilet seats!
We hid the petri dishes in a warm, dark area for several days to let our colonies grow. We will view them under the microscopes when we return to class.
Want a sneak peek?? Check out a few of the cultures below! Where do you think each swab was taken? What do you think is the germiest place in the Arboretum?
