Scientific Question How can we identify different areas of the tongue where different taste buds are located?
HYPOTHESIS WHAT IF WE TASTE SOMETHING SWEET,SOUR,SALTY,OR BITTER, THEN WE CAN WE IDENTIFY WHICH PART OF THE TONGUE IS RESPONSIBLE FOR DOING THAT?
Background When food enters the mouth,it mixes with saliva.This mixture activates the taste buds in the tongue, setting off a chemical reaction that we call “taste”
Background These taste budscan be found on the tongue in large numbers.taste buds are also found on the roof of the mouth, and in the throat.
How to locate your taste buds SSSStick your tongue out in front of a mirror and look for many little white bumps called papillae. TTTThe taste buds are found at the bottom of the papillae.
Did You Know? TTTTaste buds can identify four different tastes: SSSSweet SSSSour SSSSalty bbbbitter
Materials TTTThree small cups CCCCotton swabs TTTTap water or bottled water TTTThree pairs of latex or rubber gloves 11112 copies of the tongue map PPPPen or pencil
Materials cont. DDDDilute salt solution DDDDilute sugar solution DDDDilute vinegar solution DDDDilute white horseradish solution 11112 test tubes TTTTest tube rack
Procedure PPPPlace four test tubes in the test tube rack.The tubes should be labeled salt.sugar,vinegar and horseradish PPPPrepare a tongue diagram for each subject tested.Write the subjects name.age,and gender
Procedure Cont’d RRRRinse mouth with bottled or tap water. PPPPlace a small amount of each of the four liquids on various areas of the tongue.
Conclusion In this project, I learned that there are different types of taste buds,and they help describe different kinds of taste.
