Hypothesis

I think that people who think that different parts

of the tongue identify different tastes are wrong

and that all the tongue can identify all 4

different tastes.


4/11

The Experiment part 1

To test my hypothesis, my experiment is as

follows:

I prepare foods from the different groups:sweet, salty, sour and bitter.

The Experiment

My testers (my dad and my sister, Daisy) have

to cover their nose and wrap a blindfold around

their eyes.

tongues

Analysis of Data

In the experiment I observed that:

For sugar, both tasters thought it tasted sweet on the tip of theirtongue.

For dark chocolate, both thought it was bitter one tasted it on the backof the tongue the other tasted it on the right.

For salt, both thought it was salty but one tasted it on the side of thetongue but the other tasted it on the front and middle.

For grapefruit juice, both tasted it sour but one tasted it in the middleof the tongue and the other tasted it back and front. As well as sour,one tasted it sweet at the tip of his tongue.

This shows that there are two possibilities. One is that the tasters hadtwo different experiences. The other is that they had the sameexperience but we couldnt record it accurately. Either way bothtasters used different parts of their tongues to experience the differenttaste of each kind of food group compared to the other food groups.

Conclusion

My experiment disproved my hypothesis

because it is clear that different parts of the

tongue taste different types of taste.
