Exploring Gender and Smell

Exploring Gender and Smell | Science Fair Projects | STEM Projects
Do males and females have different senses of smell? Let's find out by having participants identify odors, quantify the intensity of the odors, and rate the favorability of the odors.


The hypothesis is that males and females have different senses of smell.

Method & Materials

You will have participants test different food items while blindfolded, and have them identify the smell, rate the level of intensity of the smell on a scale from 1-10, and rate the favorability of the smell (Undesirable, neutral, desirable).
You will need a minimum of 20 participants (10 males and 10 females), blindfolds, a data sheet, and different food items (a minimum of 3).


The results of the experiment showed that there were differences in how males and females perceived the odors. Females were more likely to rate the odors as more intense and more favorable than males.

Why do this project?

This science project is interesting because it explores the differences between genders in terms of olfactory perception.

Also Consider

Variations of this experiment could include testing different types of odors, such as perfumes or cleaning products, or testing different age groups.
