It's time to find bacteria hiding at Mt. Blue Middle School. Students will swab an area of their choice and try to grow bacteria in a petri dish filled with gelatin. We'll have a
control variable petri dish along with the
independent variable petri dish. Students will become familiar with terms in designing experiments that are valid. Hopefully the
control variable will produce nothing, while the
independent variable will show bacteria
asexually reproducing, using the gelatin as
food and
shelter.
