            Can
sugar really make you happy? When sugar
is consumed, then the mood will increase. When sugar is consumed, blood
sugar peaks. Glucose, a type of sugar, helps provide energy for most cells in
the body. Nerve cells are included in that category. Nerve cells take up half
of the energy for sugar in the body. Therefore, glucose levels and brain
function, like memory and learning, are very closely related. When the body’s
glucose levels are low, energy is low. So, when sugar is consumed, then energy
levels will increase. Increased energy levels will lead to a happier mood.
While doing this controlled experiment, 10 test subjects rated their mood on a
scale of 1-5 before and after the consuming the sugar. 

            An independent
variable is the object that is
different or changed between the experimental and control groups. It is
the factor the is being tested. It The independent variable of the experiment
was sugar. The sugar used in the experiment was a Pixy Stix. One Pixy Stix
includes about 2.14 grams of sugar. Sugar has been known to be harmful to
mental health. Researchers have found when there is an abundant sugar consumption
the risk of depression and other mental illness. Sugar was also found to lead
to addiction over time. It has also been found that sugar can worsen symptoms
of anxiety. Researches have also found the sugar can decrease cognitive
learning abilities. Some of the cognitive learning abilities is decreases are
memory and learning. The sugar, when used in this experiment, will only be
given to the experimental group and not the control group.

            A
dependent variable is the object that
is measured out of the experiment. it depends on the independent variable. The
dependent variable of the experiment was a mood scale. The mood scale measured
the test subject’s mood before the experiment started and after it ended. It
was a range of 1-5. The highest number, 5, on the scale represented the
happiest mood while the lowest number, 1, represented the saddest mood. The
middle number, 3, is expressed as neutral. However, number 2 on the mood scale
is defines a mood between neutral and sad. And number 4 on the mood scale
represented a mood between happy and neutral. The mood scale showed the
difference that the independent variable would have on the test subjects.

            The
independent variable and the dependent variable come together in the experiment
to become the focus to the experiment. In the experiment the dependent variable
is the mood scale and the independent variable is the sugar. That means that
the mood scale is dependent on the sugar. When the test subjects are given the sugar,
they must rate their mood based on the sugar. Sugar has been linked to the
brain and how it functions. This means the mood scale is affected by sugar because
sugar affects the brain which affects how you create emotions.

            This
experiment’s overall goal was to prove that sugar can increase your mood.
During this experiment the control group rated their mood 1-5 and waited 30
minutes and rated their mood another time. The experimental group rated their
mood, ate a Pixy Stix and waited 30 minutes and rated their mood again. This experiment
will help scientist in discovering if sugar really does affect mental health and
mood.

           

Methods:

            For this
experiment to be conducted, there were a total of 10 subject. Then there was a
total of 30 Pixy Stix. The test subjects were each given 3 Pixy Stix and a
paper that gave instructions and for them to record results. First, the test
subjects recorded their mood 1-5. Next, they ate the Pixy Stix and waited 30
minutes. During those 30 minutes the test subjects did not consume any food.
After the 30 minutes was up, the test subjects recorded their mood. The test
subjects did this a total of 3 times to complete the 3 trials needed for the
experimental group. For the control group, the same 10 test subjects were used.
They recorded their mood 1-5 and waited 30 minutes. During this 30 minutes they
did not consume anything at all. After the 30 minutes was up they, recorded
their mood 1-5.

 

Results:

            After
looking at the results of the experiment, one should see that the mood of the
test subject’s mood increased significantly more in the experimental group than
the control group. The average mood increase of the experimental group was 1.2,
while the average increase in mood for the experimental group was 0.1. It is
also interesting to see that the experimental groups mood increased to a 4 or 5,
with only increasing to a 3 one time, and the control group increased to mostly
3 and 4’s with one increase to a 5 and to a 2. The mood of the test subjects in
the experimental group always increased or stayed the same. But in the control
group, subject’s moods increased, stayed the same, and decreased. The moods of
the test subjects in the experimental group were a lot more positive than the
ones of the control group.

Table 1: To find the difference of the moods before
and after 30 minutes, is calculated by subtracting the initial mood by the mood
after 30 minutes. Then all the differences of moods were added together and
divided by 10 to find the average increase/decrease in mood. The sum of the
differences of mood was divided by 10 because there were ten pieces of data.

can look at the graph and easily see that the control group has a very small
increase in mood, but the experimental group has a much larger increase in
mood.

 

 

Discussion:

            The
overall goal of this experiment was to prove that sugar can increase mood.  The experimental groups average increase in
mood was 1.2 and the average for the control group was 0.1. That’s a 1.1
increase. Therefore, the overall goal was proven to be correct. The results
also showed that the increase of the experimental group was mostly 4 or 5s.
While, the control groups increase was mostly 3 and 4s. The experimental group
had a more positive outcome.

            The
hypothesis was proven by the results. The results show that the experimental
group had more of an increase in mood than the control group. Sugar is a
dopamine. A dopamine is a “feel-good” chemical in the brain. It activates a
reward center in the brain. And overtime, with addictive eating habits, it can
change how the brain functions. It is important to know this data because it
can help prove that sugar is not as bad and doesn’t lead to many issues with
the brain.

            This
experiment is relevant to the scientific community because it can help prove
that sugar may not be as bad as scientist think. Currently, scientist think
that sugar is as addictive as some drugs, but researchers can now use this
experiment to test and see if it is really that bad. They can do this many more
times than just once and see how the results change overtime. This experimental
could maybe change the course of what they have found. Scientist will be able
to track how sugar effects mood in short and long-term situations.

             Some potential modifications that could be
made to this experiment is not letting the test subjects do this on their own.
During this experiment, the test subjects may have forgotten that they could
not eat in the 30-minute waiting period. They could have also done the
experiment all in one day, when it was supposed to be done in 6 days. A way to
fix this problem is too sit the test subjects down one by one and do the
experiment and watch them record their results. Some other modification that
could be made to this experiment are the use of more sugar or a different
waiting period. This could make for more accurate results in the experiment and
seeing how sugar affects mood in different amounts of sugar and time.
