Taste Threshold Lab

The objective of this experiment is to determine the lowest concentration of a substance dissolved in water which can still be tasted; the substances that will be used are sugar, salt, and vinegar. Your threshold would be the lowest concentration value or percentage that you can still taste the solution. In other words, if your threshold level is low (i.e. .001%) then you would be very sensitive to that substance (or you could taste that substance at very low concentrations).

If your threshold level is high (i.e. 10%) then you would not be very sensitive to that substance (or you would only be able to taste that substance at high concentrations).When you were very young, your threshold was low due to the fact that your taste buds where newly developing and sensitive; there is an opposite effect when your older.
