Title
Does cheaper nail polish chip more than expensive nail polish?

Broad Question
Does cheaper nail polish chip more than expensive nail polish?

Specific Question
Does the cost of nail polish effect how much the nail polish will chip?

Hypothesis
It was hypothesized that the cheap nail polish was going to chip more than the expensive nail polish. This was hypothesized from the research that had been gathered from the internet.The other factors that lead to this hypothesis is the cost of the nail polish which is the independent variable and how mush of it chips off which was the dependent variable.

Independent Variable:
the cost of the nail polish

Dependent Variable:
how much it chips

Variables That Need To Be Controlled:
the time that the nail polish has been applied to the nails

Vocabulary List That Needs Explanation
nail polish- a substance that is made out of resins,solvent,coloring agent and film forming agent and is applied to nails to make them look pretty

General Plan
The plan is to figure out if cheap nail polish last long more than expensive nail polish. Painting every other finger nail of 10 test subjects with expensive nail polish and the other finger nails with cheap nail polish. In order to keep track of which is expensive and which is cheap they will be different colors. After that  is  taking pictures of the nails every other day, also every other day, measuring each nail to figure how much the nail polish has lasted longer . The experiment is being done at school in the science classroom.

Safety Or Environmental Concerns

Background Research
<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;"> Cheaper nail polish does last longer because the people who make expensive nail polish just want look like its worth a lot of money. Some expensive brands of nail polish are expensive for a reason because they have some expensive ingredients in it, but it doesn’t mean it will last longer than cheap nail polish.The expensive nail polish seems to last longer than cheap nail polish but it also depends on the brand itself. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;"> It depends on the brand most of the time like what they put into it and stuff but I've been to numerous websites, and one person did a comparison with the brands Barry M the cheap nail polish and O.P.I. the expensive nail polish. The person applied the nail polish on a Monday and started with the brand Barry M. By Wednesday it had minor cracks, on Thursday it was peeling and it all came off. She applied some on her toes the Saturday before and she had it on for two weeks before minor cracks showed. She applied O.P.I on a Monday and it had Small chips by Thursday. Her conclusion was that it was worth buying expensive nail polish then cheap nail polish. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;"> Another person did another nail polish cheap vs expensive nail polish. She came up with yes, it is worth buying expensive nail polish, but beware of certain types of expensive brands for they can be cheating you of your money. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;"> Cheap brands are good too, but be careful of buying of buying off-name brands for they say that type nail polish might be not good for your nails. One way to see if you are getting really good cheap nail polish is by checking the ingredients on it and it is best to avoid the ones that have fragrance in them because they are not good for sensitive skin. Some ways to warn you if you are buying really bad cheap nail polish is to look on the label to see if it has been worn, a sign of age and settling of color at the bottom of it, is that it has been on the shelf for a long time.

Detailed Procedure
<span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-align: justify; text-decoration: none; vertical-align: baseline;">1. Buy five cheap nail polish and five expensive nail polish <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-align: justify; text-decoration: none; vertical-align: baseline;">2. Get 10 test subject girls (7th or 8th grade) <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-align: justify; text-decoration: none; vertical-align: baseline;">3. Clean nails with nail polish remover before applying nail polish <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-align: justify; text-decoration: none; vertical-align: baseline;">4. Apply nail polish let it dry for 5 minutes <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-align: justify; text-decoration: none; vertical-align: baseline;">5. Create folders to store individual test subject’s photos of nails with their names on it (on paper not computer) <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-align: justify; text-decoration: none; vertical-align: baseline;">6. Every f block, take pictures of their nails if a test subject is absent erase all data gathered from that test subject <span style="background-color: transparent; color: #000000; display: block; font-family: Arial; font-size: 16px; text-align: justify; text-decoration: none; vertical-align: baseline;">7. Keep doing this until 3/20 then compare the results to answer the question of “does cheap nail polish last longer than expensive nail polish

Conclusion
<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">This experiment was based on figuring out if cheap nail polish lasts longer than expensive, and if it was going to chip more. The independent variable of this experiment was the cost of the nail polish. The dependent variable was how much it chips. The cheaper nail polish chipped more than the expensive nail polish. The cheap average was 194mm2, and the expensive average was 140mm2.

Discussion
<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">The question was “does cheap nail polish last longer than expensive and does it chip more?” The question was answered, and the answer was very clear that cheap nail polish does chip more, and it doesn’t last longer than expensive. The evidence was on the trials fingers, that is how the answer was discovered. The finger nails proved the answer to be correct. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">The hypothesis was supported by the results, the hypothesis was the answer. It was hypothesized that the cheap nail polish would not last longer than the expensive and it would definitely chip more. And the hypothesis turned out to be true. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">The patterns that could be identified within the data and observations, it was found consistently that the expensive nail polish would always chip less than cheaper nail polish. We used several brands which was the independent variable and the dependent variable is how much chipped off which was constantly changing over the days <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">During this experiment there was a couple challenges one of the ones we could not have controlled was that two of the girls scratch off their nail polish and therefore had to delete the data collected from them. We could have improved this project by asking what the test subjects did during their day that cause chipping different people have different things they do so it could chip faster or slower but it didn’t matter what type of nail polish. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">The information that was used mostly came from beauty websites giving opinions about which is the best nail polish to be used, some of the suggested were used in this experiment. The only technology that was used during this experiment was a digital camera to take pictures of the test subject’s nails and a computer to put down the data. The results that we gather will help people with the same question by the brands of nail polish used in this experiment so the person will know how much chipped off with that brand. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">The knowledge gained from this experiment could be of use to anyone. Anyone who wears nail polish and is looking for a great nail polish to use that will not chip. The problems that is might help solve would be, the use of nail polish. The results would help many people choose the best type of nail polish. Mostly teenage girls, but also adults, and children. The new breakthroughs in information would be, which brand would be better so that they would not waste production on other nail polish brands and just use the several brands that will last the longest and is better for your nails.
