Science Buddies: "Ask an Expert"

My experiment is Does age affect the ability to taste salt? https://www.sciencebuddies.org/science- ... p026.shtml
I need to know the control group for this topic, I have already conducted the experiment and I need to hand in a report soon, please help!

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.
