germs on your hand will be cleaned. Materials: The materials we used in this lab were a petri dish with agar‚ forceps‚ water‚ alcohol‚ hydrogen peroxide‚ antibacterial soap‚ filter paper disc‚ tape‚ and a permanent marker. Procedure: We started this lab on May 12‚ 2014. Using a permanent marker on the bottom of the dish‚ we divided it into 4 sections. We labeled the sections‚ W (water)‚ A (alcohol)‚ S (soap)‚ and HP (hydrogen peroxide). Then‚ we labeled the perimeter of our dish with our initials
