Taste Buds

Your sense of taste begins on your tongue. It has 10,000 tiny bumps called taste buds. Receptors in your taste buds react to chemicals in food and then send messages to your brain. The taste buds can tell the difference between four basic tastes. Salty, sour, sweet and bitter. Your taste buds are constantly being replaced. On average, a taste bud lasts for ten days.

Today we got to try several different tastes: sweet, sour and bitter. We tried lemons, raisins, citrus peel, sour babies, jelly beans and 90% cocoa dark chocolate. We thought the chocolate would be sweet and delicious, but we were wrong it was bitter and we couldn't eat it. The citrus peel was no bad a little sour and sweet. We discovered that bitter tastes at the back of your tongue, sour in the middle and sweet at the front. We had to think about the flavours and what part of our tongue was reacting. We all had a great time taste testing.
