Bacteria Growth Essay

690 words - 3 pages GROWTH OF BACTERIA INTRODUCTION Is there a difference in germ killing when using antibacterial soap or hand sanitizer? When using hand sanitizer or antibacterial soap one is more likely to have a lower bacteria count than the other. Other factors contribute to the less bacteria count like the amount of time one washes their hands and the amount of soap one uses. If two groups were to wash their hands one with hand sanitizer and the other with antibacterial soap then the group who washed their hands with hand sanitizer should have a lower bacteria count.
