Our ability to identify natural and synthetic scents
The hypothesis that most participants will not be able to differentiate between natural and synthetic scents is proven to be correct.
One of the first lines of perfume to use artificial scents was Channel No. 5 by Coco Chanel. This perfume was created in the 1920s and it is still in the market today. The perfume uses aldehyde and a mixture of several scents. There are many perfumes sold today that uses aldehyde because it adds a “sparkle” to the scent.
Try repeating this science fair project, to determine how sensitivity of smell may vary according to the participant’s age?
The experiment can also be done to compare the ability of male versus female participants to effectively differentiate between natural and. synthetic fragrances.
