Over the past week 6MT have been designing and carrying out our own experiments related to growing bacteria. Each group did a different investigation e.g. the amount of bacteria on different door handles, swabbing each other’s mouths or whether  a book or computer mouse has more bacteria. First we collected our equipment; a plastic cup, some Petri dishes filled with a agar, cotton buds and the objects we are taking the bacteria samples from. We filled the cups with water and dipped the cotton bud in; then we took a sample of our objects by wiping the wet cotton buds on them; after we transferred it onto the agar. Next, we sealed the Petri dishes with cellotape and added a label. Finally, we stored our experiment in a warm, dark box for 6 days. Check out our results…..
