This week in science we did an experiment, what did is we got petrie dishes with agar in them and on the bottom it was separated into 4 quadrants and in a group we chose different things for every person in our group and when when you got home you would swab the thing that you chose and rub it gently onto the agar then we brought them bak to school and put them on the heater, and then the bacteria grows on the agar. We also watched some people present and worked on our slides.
