Smelling the Difference

Smelling the Difference | Science Fair Projects | STEM Projects
Do you think you can tell the difference between smells? Put your nose to the test and find out! In this experiment, you'll be blindfolded and asked to identify different smells.


The hypothesis is that people can recognize a wide variety of smells.

Method & Materials

You will collect several items that have distinctive smells and have people guess the smells.
You will need a blindfold or container to hold the smelly items, and smells such as lemon, orange peel, cedar wood, perfume soaked cotton, banana, pine needles, chocolate, coffee, dirt, vanilla, garlic, onion, mint, vinegar, rose flowers, saw dust, ginger, peppermint, and pencil shavings.


The results of the experiment showed that common and more distinct smells were easier for people to guess, while smells that were similar were hard for people to distinguish.

Why do this project?

This science project is interesting and unique because it tests a person's sense of smell and how well they can distinguish between different smells.

Also Consider

Experiment variations to consider include testing different smells, or testing people with different levels of sensitivity to smells.
