GUM FLAVOR
Which brand of gum has longer
lasting flavor?
November/December 2004
Hypothesis
My hypothesis:
I hypothesize that Juicy Fruit’s flavor will last longer than the
other brands because it says “now with longer taste” on the
package.
How will I test this?
I will test how long the flavor of each brand lasts by chewing
each brand of gum until the flavor is gone.
How will I make this a fair experiment?
I will taste test each brand four times, time how long the
flavor lasts, and then record the results.

Conclusion (Part One)
So was my hypothesis right?
My hypothesis was proven right. The
flavor of Juicy Fruit gum lasted the longest
in all four of my tests.
What did I learn?
I learned that Juicy Fruit brand’s flavor
lasts longer than Bubble Yum and
Bubblicious while doing this experiment.
Conclusion (Part Two)
Any recommendations?
I recommend Juicy Fruit brand of gum because in
all four of my experiments, Juicy Fruit gum
lasted the longest for flavor out of Bubble Yum
and Bubblicious.
Would You Change Anything?
Next time I would change the brands of gum I
choose and get ones with the same amount of
grams in each piece to see if it would change my
answer.
Conclusion (Part Three)
Any errors?
My source of error was that I couldn’t chew each
piece at the same speed. This would cause the
flavor to disappear faster or slower depending on
the speed the gum was chewed.
Any Problems?
When doing this experiment, I had a problem with
chewing each piece at the same speed and
chewing gum all day, because it made my jaw
sore.
Conclusion ( Part Four)
Was this a fair experiment?
This was a fair experiment. The chewing speed
probably did not affect the final conclusion
because the amount of time the flavor lasted in
each test was so far apart.
What is your new question?
A new question I now have is, will Juicy Fruit’s
flavor last longer than other brands of gum (other
than Bubble Yum and Bubblicious)?
