Problem Statement:
Do girls really have a better sense of smell
than most boys?
Hypothesis:
I believe that girls will
identify the smell better because “they have more brain cells in the smelling
area of the brain”.
Independent Variable:
Different Items to smell.
Dependent Variable:
Number of items correctly identified.
Materials:
- Lemon
- Cinnamon
- Popcorn
- Peppermint soaked in cotton ball
- Salt and Vinegar chips
- Duct Tape
- Mini Plastic cups
Volunteers:
Boys
1.Brady
2.Elijah
Girls
1.Reyna
2.Emily

Procedures:
- Take strong
smelling items and put them in each plastic cups.
- Put duct
tape over the cups with the different items inside.
- Poke holes
on top of the duct tape and enclose it in a tight space.
- Have
volunteers tell you what they smell.
- Record the
data.
- Plot the
graph and analyze the result, compare with the hypothesis.
- Conclude
the result.
Conclusion:
After the experiment, I
concluded that girls have passed the smell test! However, with the sample size
of 4, the result shows that girls have better experiences in smelling things.
Furthermore, this project can be extended by increasing the sample size.
