What Kills Germs? Lab Report
I. What Kills Germs:
II. Statement of the Problem: A. What antibacterial substance disinfects an object the best? B. Background information about Bacteria is that they are fast growing organisms that need to be contained. C. Independent Variables: antibacterial soap, household bleach, household disinfectant, penicillin, amoxicillin, erythromycin D. Dependent Variables: Hemophilus influenzae, Straphylococcus aureus, Streptococcus
E. Control Variable: Sterile Filter Paper
III. Hypothesis: If the most effective solution for pathogenic bacteria is household bleach, then the descending order from best to least are household bleach, Penicillin, Amoxicillin, Household Disinfectant, Anti-Bacterial Soap, Erthromycin, Sterile Filter Paper.
IV. Materials: A. The materials used in this lab include a agar, a petri dish, test tubes containing the pathogenic bacteria: Straphylococcus aureus, Hemophilus influenzae, Streptococcus, and antimicrobial agents such as antibacterial soap, household bleach, household disinfectant, penicillin, Amoxicillin, Erythromycin.
V. Procedure:
1. Introduce the agar into the petri dish by adding the test tubes containing pathogenic bacterial stock culture- Staphylococcus arueus, Hemophyilus influenzae, or Streptococcus pneunoniae.
2. Vials one through seven contain filter paper disks that are soaked in antimicrobial agents such as household disinfectant, antibacterial soap, household bleach, penicillin, amoxicillin, and erythromycin, or in sterile water. Place a disk from each file and put it in the petri dish.
3. If you are interested in learning more about specific pathogenic bacteria, antimicrobial agents, click the Microbiology book to learn more
4. Click the incubator to put the petri dish in it.
5. Click the red button on the incubator to turn the incubator on. When the timer shows that 24 hours have past, remove the petri
