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.
