How do the results of the four trials compare?
They all start out with 4 being the most dirty.
What, if any, errors or inconsistencies may have occurred in this experiment?
Using too much paint on one person than the other
What suggestions do you have for improving this lab and minimizing errors or inconsistencies? Be specific.
Probably adding more people, to test out the project, also how much water you should use when washing off the paint because if you use a little more water pressure than the other person, then the paint will come off more and mess up the test results.
Based on these results, what is the importance of soap and time for effective hand washing?
It's important because if you add too much soap for one person and too little soap for the other person, but still at the same time, the results would be less effective.
What areas of the hands retained the paint the longest, requiring careful scrubbing to get clean?
The nails, and the creases in the hand.
Analyze the graphs. What do they indicate about the time it may take to effectively wash your hands?
It takes at least 20 seconds to effectively wash your hands.
Describe the various defense mechanisms your body has to fight pathogens, nonspecific and specific. How does not washing your hands properly affect these mechanisms?
When you don't wash your hands, it leaves so many germs on your hands, and then you touch a lot of other surfaces that other people also come in contact with.
