My project looked at the affect of four
types of gum (hot, cold, sour and sweet) on your mouth
temperature. I checked to see if the a person could tell
the gums apart by taste alone and if there was any real affect
on the temperature of your mouth after chewing the four gums.
My Hypothesis Was
|Discussion and Conclusions
Now that I have completed my experiments I can tell you that my
hypothesis was wrong. As you can see in figure one below
there was an affect of the different types of gums on mouth
temperature when I compared it to chewing with no gum.
The results of the gum blind taste test showed that, most of the
time, a subject could tell if the gum was hot, cold, sweet or
sour correctly. See Table 3. In only two test out of the sixteen were
the test subjects incorrect. This shows that people can tell the
type of gum they are chewing just by the flavour.
My graph (Figure 1) of mouth temperature after chewing the four
gum types shows a difference in mouth temperature between gum
types. I found out that the hot chewing gum had the highest
mouth temperatures when compared with the other chewing gum
types and the mouth temperature after chewing with no gum. All
three other gums (Sweet, Sour and Ice) showed a slightly lower
mouth temperature when compared to the mouth temperature after
chewing with no gum.
There was not much difference in temperature between the sweet,
sour and cold chewing gums.
My hypothesis is was wrong and the type of gum did have an
effect on your mouth temperature. The Fire gum did raise the
mouth temperature and the Ice gum did make your mouth colder,
but so did the sweet and sour gums.
I found out that gum is not only about taste, it does affect your
mouth temperature and the bacteria in your mouth.
