Today we checked for bacteria growing in certain locations of the room and school. Here, Trevor and Alan swab and label their agar plate. The plates will spend 24 hrs in the incubator. Bacteria grow best in dark, moist, and warm places so we've created the best conditions and an optimal food source for them to thrive.
Sam and Courtney test for bacteria on the exoskeleton of our pet cockroach.
