Can You Smell the Difference? | Science Fair Projects | STEM Projects
Do you have a good nose? Put it to the test and find out if you can tell the difference between natural and synthetic scents. In this experiment, you'll be given a variety of scents and asked to identify which ones are natural and which ones are synthetic.

Hypothesis

The hypothesis is that most participants will not be able to differentiate between natural and synthetic scents.

Method & Materials

You will purchase bottles of natural and synthetic scents, separate tissues into groups, and mark them with the scent name. You will then place a drop of natural or synthetic fragrance on each tissue and ask participants to identify the natural scent.
You will need a bottle each of natural and synthetic scents, 200 pieces of tissues, 10 participants, and a black marker pen.

Results

The results showed that 8 out of 10 participants were unable to make more than 6 correct choices, indicating that 80% of the participants were unable to differentiate between natural and synthetic scents.

Why do this project?

This science project is interesting because it tests the ability of people to identify natural and synthetic scents, which is something that we use in our everyday lives.

Also Consider

Consider repeating this science fair project to determine how sensitivity of smell may vary according to the participant’s age, or to compare the ability of male versus female participants to effectively differentiate between natural and synthetic fragrances.
