What is taste?

Taste is one of the five senses, the others being sight, smell, touch hearing. Our chief organ of taste is the tongue, which is covered with tiny cells or taste buds. These react to different taste and send messages to the brain
You may be surprised to learn that there are in fact only four kinds of taste; sweet, sour, salty and bitter. All the flavours we know are a combination of these four.
Just as there are four kinds of taste, so there are four kinds of taste bud, and these are situated in different areas of the tongue. Only the centre of the tongue has no buds at all, as you will see if you put a little salt on the middle of your tongue. Experiments with other flavours to find the areas of taste buds on your tongue, and then see how placing an ice cube on your tongue affects your sense of taste.
