This activity is a variation of an activity that I have completed with my students.
The tongue is the organ for taste. but your tongue can only sense four basic flavors: sweet, salty, sour, and biter.
Your sense of smell is much stronger than your sense of taste. Often when you think you are tasting something, you are really smelling it.
