2. How does the use of the different cleaning products(dial hand soap, softsoap hand soap, Purel hand sanitizer) effect how good the hands are cleaned?(are they false advertisers about killing 99.9% of germs?)

3. As I use three different kinds of hand cleaning supplies then we will know if the advertisements are false because it will shows the germs in which were left by the cleaner under a black light.

4. Black light Glitterbug potion Two hands Dial hand soap Purel hand sanatizer Stopwatch camera

6. 1.Set up diagram 2.Apply a dime size amount of glitter bug potion onto hands of each person(3 people) 3.Rub in thoroughly for 10 seconds 4.Go under a UV light(black light) and view the germs on your hand that are fully white(in a very dark room) 5.Go somewhere that has a sink and wash hands for 30 seconds with one pump of each soap.(hand sanitiser) with warm water 6.Dry hands off 7.Go back under a UV light(black light) and observe how good the cleaning supplies cleaned the germs off 8.Record the estimated amount of germs that came off after washing 9.Repeat steps 1-9 2-3 more times after washing hands until fully clean(no white under black light 10.Answer the problem/ question: how does the use of the different cleaning products(dial hand soap, softsoap hand soap, and purel hand snitiser) effect how good your hands get clean?(are they false advertizers about killing 99.0% of germs?

8. In my experiment “No white under black light”, my hypothesis was correct. The Dial hand soap did work the best. The hand sanitizer unfortunately did not work good at all. this shows what we should use to clean our hands. The highest average of cleaning the germs off our hands was 83% clean, which was cleaned by the dial hand soap. The lowest average of cleaned off germs was 16% which was cleaned by the Purell hand sanitizer. The difference of those are 71 %. That’s a huge difference. This proves that we should wash our hands with dial hand soap because it gets 83% of germs off our hands. We should not use Purell hand sanitizer. So this supports my original hypothesis.

9. The purpose of my project was to find out what is the proper product to use to clean our hands. Before I tested which product would work the best. I believed that the Purell hand sanitizer would get the most germs off/kill the germs. It turned out I was incorrect. If I had used maybe two pumps of the cleanser my results may have been different. From doing and completing this project I have learned we should use dial hand soap over anything else, and wash our hands instead of using hand sanitizers.

10. In my science fair project I incorporated four main things. These are the soaps and germs there are dial handsoap, softsoap hand soap, purell and saintizer, and the glitterbug potion Dial hand soap is a antibacterial soap with moisturizer. It smells really good. It is #1 ddocter recommended. The active ingredient is Triclosan which is 0.15% of the soap. This ingredient is used for antibacterial. This soap is used for hand washing to decrease bacteria or the skin. Softsoap hand soap is an antibacterial hand soap. It smells like air freshener depending on what kind you get.
