My experiment is Does age affect the ability to taste salt? https://www.sciencebuddies.org/science- ... p026.shtml

Hi Alina,

Good question. This is a really great project. If you did the experiment as described, then the control is the sample with no salt in it.

Let us know if you have any other questions.
