P3NS carried out a science experiment as part of their topic on The Body. They tested their sense of taste by placing small amounts of sweet, sour, bitter or salty tasting drops onto their tongues, using the end of a straw.
They found out that different parts of our tongues are sensitive to different tastes. The tip is sensitive to sweet tastes, the back to bitter tastes and the sides to salty and sour tastes. Looks like they had a lot of fun in the process. Why not try it at home?!
