Taste Buds
Submitted by:Isaiah Harrell
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
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


Stick your tongue out in front of a mirror
and look for many little white bumps called

The taste buds are found at the bottom of
the papillae.


Dilute salt solution
Dilute sugar solution
Dilute vinegar solution
Dilute white horseradish solution
12 test tubes
Test tube rack
Procedure


Place four test tubes in the test tube
rack.The tubes should be labeled
salt.sugar,vinegar and horseradish
Prepare a tongue diagram for each subject
tested.Write the subjects name.age,and
gender
Procedure Cont’d


Rinse mouth with bottled or tap water.
Place a small amount of each of the four
liquids on various areas of the tongue.
Conclusion
In this project, I learned that there
