Antibacterial Hand Soap Science Fair Projects

Antibacterial hand soap science fair projects begins at scifair antibacterial hand soap.

PROCEDURES

1. Gather the signed permission slips
2. Get the materials
3. Obtain the subjects
4. Swab the subject’s left hand (5 times in a left/right direction, 5 times in an upward/downward motion)
5. Put swab away in bag marked with subject’s number and hand (L/R)
6. Repeat steps 4,5 on the rest of the subjects
7. Show the subjects the method to wash their hands (10 seconds on the top, 10 seconds on the palm, 10 seconds between the fingers, 10 seconds rinsing)
8. Have the subjects’ wash their hands with anti-bacterial hand soap in water, under the same sink
9. Swab the subject’s right hand (5 times in a left/right direction, 5 times in an upward/downward motion)
10. Repeat step 5
11. Repeat steps 4-10 with non-anti-bacterial hand soap
12. Rub/twirl one swab onto one blood agar plate in an up/down motion
13. Turn the plate 45 degrees
14. Repeat steps 11 and 12 for each bag, with same label as the bag
15. Place blood agar plates into the incubator for 72 hours
16. Come back to the hospital in 72 hours
17. Take blood agar plates out of incubator
18. Count colonies with naked eye under a white light
19. Record data

RESULTS

The original purpose of this experiment was to determine the effect of antibacterial and non-antibacterial hand soaps on the amount of bacteria on the hands.

The results of the experiment were that the non-antibacterial soap removed more bacteria than the antibacterial soap. Also, the non-antibacterial hand soap did remove more than 50% of the bacteria.

CONCLUSION

My first hypothesis was that anti-bacterial hand soap would remove more bacteria than non-anti-bacterial hand soap.

The results indicate that this hypothesis should be rejected, because the amount of bacteria on the blood agar plates with antibacterial soap was greater than the plates with non-antibacterial testing.

My second hypothesis was that non-anti-bacterial hand soap would remove at least 50% of bacteria from the washed hands. This hypothesis should be accepted.

After thinking about the results of this experiment, I wonder if different brands would change the results of this experiment. I also wonder if the amount of time spent washing would reduce more bacteria.

If I were to conduct this project again, I would test a different brand of soap, and try to see which active ingredient removed more bacteria. 3rd party contributor
