Taste Test Challenge | Science Fair Projects | STEM Projects
Do you have what it takes to be a taste tester? Find out by testing your tongue's sensitivity to different tastes. See if you can tell the difference between sweet, sour, salty, and bitter.


The hypothesis is that the tongue is the most sensitive to sourness.

Method & Materials

You will test 50 participants by giving them salt, sugar, lime juice, and bitter chocolate.
You will need 50 participants, 50 plastic spoons, 50 blindfolds, 1 kg salt, 1 kg sugar, 50 limes, and 1 kg bitter chocolate.


The results showed that most participants tasted the bitter chocolate the most acutely. This proves that the tongue is the most sensitive to bitterness.

Why do this project?

This science project is interesting because it tests the sensitivity of the tongue to different tastes. It also shows how different people can have different levels of sensitivity to taste.

Also Consider

Consider testing different types of food or heating up the food to see if the results change.
