Tessa Nelson9th GradeBellwood Antis High School

Sense of TasteGirls & boys have same # of taste buds but girls have a higher sensitivity level

Boys need an average of 10% more sourness and 20% more sweetness.

The Sweetness is what I’m testing.

Girls do have a better sense of taste then boys.

HypothesisGirls will be able to tell the difference between

the variety of Coke products better.

Six Dixie cups, filled with 40 milliliters of the Coke products, and one with water

The blindfolded subjects come in and drink the soda one by one, drinking the water after each.

They were told what choices they could chose from.

They told us their answers after each drink.

Experimental Procedure

Step 1Fill the Dixie Cups up

to 40 milliliters with the 6 different Coke products and water.

Step 2

Step 5

Bring the subjects in one at a time, in the pattern of Boy, Girl,

Boy, Girl.

Step 6

Set the students in the same seat when

they come in.

Step 7The different

samples will then be placed in front of

them.

Step 8

Have them drink the samples one at a time.

Step 9After each sample, have them drink 40 milliliters of

water.

Step 10

After each sample, record their guesses.

Conclusion

My data does not support my hypothesis. Therefore I reject my hypothesis; Girls

can not tell the difference between coke products better than boys.

If I were to do this

again..

Other
