Who Has a Better Sense of Smell, Boys or Girls Ben S 2013-2014

ABSTRACT The purpose of this experiment was to see if it was harder to smell objects when the objects were frozen for ten min. The human’s sense of smell works and this is how; the nose smells the object, then the nose sends waves to the human brain, and last the brain tries to identify the smell by seeing if it smelled other objects similar to what this object smells like. The most important method was freezing the objects for ten min. Then seeing if the host of the experiment could try to identify them when the objects came out of the freezer, then the next day the host of the experiment wouldn’t freeze them and see if the host of the experiment could identify them better. A human’s results were that the experiment was successful and it was harder to smell the objects when the objects were frozen. The smells are harder to identify while frozen because when the objects were frozen, it basically changes the smell entirely.

EXPERIMENTAL IMPROVEMENTS AND FUTURE EXPERIMENTS One thing the host could improve on in this experiment is blindfolding the test subjects. Another thing the host could improve on is adding things to the smells and combining the smells. Some future experiments that could be made are combining smells and see if they could identify both smells. Another experiment that could be made is having them see the smell and see if that helps them identify the object.
