Title:
The Best Nail Treatment to Lengthen Nails
Goal / Objective:
To discover what nailpolish or nail treatment works the most effectively to enhance nail growth.
Hypothesis:
I suppose that a nail polish consisting of a formula of protein will help nail growth the most, because nails are made of keratin, which is a type of protein. Therefore, once the vitamins have copletely absorbed into a nail, it will be full of extra nutrients.
Materials:
- - 1 person (with 10 fingernails)
- - 2 different mixtures of nail polish (both promote nail growth)
- - 2 brushes to apply nail polish
- - 2 nail polish bottles
- - 140 cotton balls
- - 1 ruler
- - 1 bottle of nail polish remover
Variables:
Independent:
- the different kinds of nail polish
- 1 person (with 10 fingernails)
Dependent:
- the length of the nails after each application and measurement
Control:
- the quantity of applied nail polish each time
- the length of time the nail polish is on the nails and removed
- the same nail polish remover is used each time
- the diet and nutrition of the individual
Procedural Steps:
1. Use a ruler to measure each of your 10 fingernails, from the cuticle to the tip.
2. Record the length of each one.
3. Pick 3 fingernails to apply one type of nail polish, and 3 more for the other type of nail polish.
4. Leave the other 4 natural.
5. Apply the nail polish to the correct finger nails in the morning.
6. Remove it at night and then reapply to the same fingernails.
7. Measure again after 7 mornings and nights of following steps 1-6.
8. Record the differences between the first and second measurements for each nail.
9. Repeat steps 1-8 4 more times.
10. Calculate the average growth on each nail, and indicate which product was used.
