Science Buddies: "Ask an Expert"

Hi I am doing a experiment that you gather volunteers and let them try try different food types (sweet, sour, salty, spicy, etc.) with nose plugged
and and unplugged to see how smell affects the taste. But I dont know what my independent and dependent variables. Can you please help me? The topic is on the science buddies "The nose knows smell but how about taste?" on human biology and health section.

Hi,

This is a great project, that is fun to do.
