Abstract
Gumcentration, our science fair project, explores the numerous simple ways we can help people concentrate
better with more focus on everyday tasks. Gumcentration tested fourth and fifth graders on their ability to
concentrate with different techniques. The first test involved completing a normal math worksheet. The second
test involved completing a blue-colored math worksheet. The third test involved completing a normal math
worksheet with a gripped pencil. The fourth test involved completing a math worksheet while chewing gum.
Testing seventh graders, classical music helped more than the control group. Results show that for the entire
fourth grade and fifth grade males, chewing gum helped the most, with the highest average percentile of
accuracy. Blue paper helped second most, pencil grips helped third most, and having nothing received least test
scores. However, for the fifth grade females, pencil grips helped the most, followed by blue paper, chewing
gum, and having nothing. For the seventh grade, classical music helped the most. Comparing everything
together, classical music helped the most. Our hypothesis was proven correct. These variables helped our
subjects concentrate more. Our project is very beneficial to real-life. As for school, improving the level of
concentration allows the work to be completed efficiently and with an increase in productivity. This can lead to
better grades and can boost morale and confidence. It will help in higher grades when more and more work has
to be completed quickly. For example, if you get an essay done a day early, you can take a day to relax and
rejuvenate. Also, playing classical music, chewing gum, using a pencil grip, or using blue paper during
standardized testing can improve student scores, which can lead to improvement in school scores and ratings.
Previous Background Research
Concentration and attention are two essential components to everyday work and tasks. Many substances and
techniques can be used to please the senses and help these two aspects of your brain. These substances include
caffeine, chewing gum, music, lemon essential oil, a few prescription drugs, and various creative techniques.
Chewing gum, invented as old as the Neolithic era, was intentionally used for medical and oral purposes. But it
has been proven that chewing gum may actually help the ability to concentrate. A study in Germany conducted
at the University of Oldenburg showed that chewing gum had a positive and significant effect on a
concentration test. A study in Wales conducted by Cardiff University showed that chewing gum improves
selective attention, alertness and vigilance. Researchers at the Baylor College of Medicine found that students
who chewed gum showed an increase in standardized math test scores and their final grades were better
compared to those who didn't chew gum. Students who chewed gum had a significantly greater increase in their
standardized math test scores after 14 weeks of chewing gum in math class and while doing homework
compared to those who did not chew gum. Chewing gum was associated with a three percent increase in
standardized math test scores, a small but statistically significant change. Students who chewed gum had final
grades that were significantly better than those who didn't chew gum. A similar study by the Baylor College of
Medicine showed that chewing sugar free gum improved standardized math test scores by 3%. A study at the
University of Northumbria showed that chewing gum improved the ability to remember large chunks of
information by approximately 35%. A California state science fair project conducted by Lily C. Goldman found
that chewing gum improved the ability to play a memory game by approximately 70%. What do all these
studies show in common? They all show that chewing gum improves concentration, memory, and focus. Why
is this? It may be because chewing gum raises an average human’s heart beat by around 3 beats per minute
(BPM). The study at the University of Northumbria also found people who carried out the motion of chewing
gum but didn’t actually have it present in their mouth had their heart rates increase by 2 BPM. Another reason
may be that chewing gum triggers a production in insulin, which improves the ability to memorize and focus. A
third possibility is that it might not be the gum itself that helps concentration but rather the act of chewing.
Either way, chewing gum is significantly beneficial to concentration, memory, and focus.
Caffeine is a naturally-occurring substance in plants like tea leaves, cocoa and coffee beans that acts as a mild
stimulant drug when consumed by humans. In fact, it is the most popular stimulant drug in the world. However,
it is most widely known to improve concentration and alertness. A study in 2005 by the Medical University at
Innsbruck, Austria, determined that caffeine promoted increased activity in specific areas of the brain that are
involved in planning, attention, monitoring, and concentration. Studies from the London University of Hygiene
showed that caffeine improved cognitive abilities, reasoning ability, and alertness. A study at the Swinburne
University of Technology in Melbourne, Australia showed that despite being well rested, administration of
caffeine significantly increased alertness and enhanced performance. What do all these studies show in
common? They all show that caffeine improves concentration, focus, and alertness. Why is this? Scientists
believe that caffeine interferes with the action of the neurotransmitter adenosine. Adenosine has a calming
effect on the brain, so the result of its interaction with caffeine is increased alertness and wakefulness. Another
possibility is that the fact that caffeine stimulates the central nervous system which alleviates fatigue, increases
wakefulness, and improves concentration and focus.
Lemon essential oil is yellow essential oil squeezed from a lemon rind. It has a sharp, fresh, clean, strong,
purifying, sugary citrus and slightly sour smell. It is pale greenish-yellow in color, and is watery in viscosity,
originated in India. A study in Japan showed that diffusing certain aromas in an office environment dramatically
improved mental accuracy and concentration. Diffused lemon essential oil resulted in 54 percent fewer errors.
When aromas were diffused during test taking, scores increased by as much as 50 percent. It is now used in
Japanese factories and workshops to promote concentration. An anonymous study not only showed that lemon
essential oil improved concentration but also showed it improved decision-making. Lemon essential oil also
prevents migraine headaches, which decrease concentration. Why do lemons and lemon essential oil help
concentration? According to YoungLiving, lemon essential oil promotes clarity of thought and purpose and
energizes and stimulates the mind and body, which freshens the body and provides relief. Another reason may
be that lemon essential oil primarily activates the hippocampus, which affects short- and long-term memory.
Lemons aren’t the only things whose scent and essential oil helps concentration. Mangos, apples, and bergamot
oranges all promote concentration. Certain herbs and spices such as cardamom, basil and rosemary can help
improve concentration. These scents help fight the effects of stress and mental fatigue that can lead to having a
difficult time concentrating. The outdoor scents of pine, cedarwood, and eucalyptus are used to help fight
difficulties with concentration. These scents help boost energy levels as well as focus, and eucalyptus can be
combined with other scents for a refreshing change. Peppermint has been shown to increase alertness for long
periods of time. Peppermint also can relieve migraine headaches, which can cause a decrease in concentration.
The scent of peppermint can also relieve difficulty concentrating that is caused stress and mental fatigue.
Classical music is a type of music often involving large orchestras and typically exists without vocal
accompaniment. Violins, flutes, clarinets, and pianos are some of many instruments used within classical music.
Bach, Mozart, and Beethoven are some the most recognizable and famous classical musicians. Classical music,
when played, is shown to help concentration. A study at the Australian Music Association not only showed that
classical music improved concentration but also showed improvement in reasoning capacity and problem
solving skills, math and language performance, memory, greater social and team skills. Arthur Harvey, a wellknown neuromusicologist, proved that listening to Johann Bach’s music is the most beneficial type of classical
music to concentrate. A study at the University of Maryland showed that Baroque classical music improved the
ability to concentrate for ⅞ of the subjects tested. Other studies have also correlated baroque classical music
with improved spatial reasoning, attentiveness and concentration. Another anonymous study proved that
listening to Mozart improved concentration and IQ during that period of time. Why does music help you
concentrate? According to Stephan Christman, professor at the University of Toledo, one of the major factors of
concentration is the person's arousal level. A quiet room can cause a person to have a low arousal level, while a
room with a lot of activity will cause them to have a high arousal level. The key to focus, Christman says, is
achieving an optimum level of stimulation. The reasoning for music helping concentration according to Stephan
Christman is that music can help solving the issue of the split between the right and left hemispheres of the
brain. While the left hemisphere is better at dealing with concentration, the right hemisphere deals with
complementary attention, such as reacting to a phone ringing. Playing music while studying allows the right
hemisphere to "enjoy itself" and not get bored while doing something that would normally be very tedious.
There are many prescription drugs that can help concentration. These types of drugs are known as
amphetamines. Ritalin, a stimulant drug best known as a treatment for hyperactive children, is proved to help
concentration, alertness, and focus. Similar ADHD (attention deficit hyperactivity disorder) drugs such as
Adderall and amphetamine Dexedrine have the same effects. Adderall was originally intended for bicyclists in
Belgium who had to stay awake during nighttime races. Scientists say that these drugs improve concentration
because the stimulant increases the levels of dopamine in the Central Nervous System. Dopamine released in
the brain creates a sort of reward for the body when experiencing something pleasurable, creating a sense of
euphoria. A separate study showed that Donepezil and Modafinil greatly improved a pilot’s ability to fly at
nighttime compared to placebo, caffeine, and any other amphetamines.
Hypothesis
If a student is completing a worksheet, then chewing gum, having the worksheet blue, using a pencil grip, and
listening to classical music will improve their concentration and test score.

Results
Our results show that most of the subjects in 4th and 5th grade received their high scores while chewing gum.
The only exception was the 5th grade girls, who received their high scores while using a pencil grip. However,
they all show that they received their second high scores working on a blue-colored paper and received their
least score using regular paper. Our hypothesis is proven correct. Classical music, chewing gum, blue-colored
paper, and pencil grips in fact did help our subjects concentrate more on their worksheet. However, they all
helped at different levels. For the 4th grade, chewing gum helped improved the most. For the 5th grade, pencil
grips help the most. For the 7th grade subjects, music helped concentration in seventh graders. Comparing all of
these together, classical music (non-vocal) helped the most.
Conclusions
Our hypothesis was supported by our data. Chewing gum, blue-colored paper, pencil grips, and music in fact
did help our subjects concentrate more on their worksheet. However, they all helped at different levels.
Classical, non-vocal music helped the most, increasing the seventh grade scores by approximately 68%.
Chewing gum helped the second-most, increasing fourth and fifth grade scores by approximately 32%. Blue
paper helped the third most increasing fourth and fifth grade scores by approximately 25%. Pencil grips helped
the fourth-most increasing fourth and fifth grade scores by approximately 32%. The control group had the
lowest scores.
The answer to our problem, how to help students concentrate without the use of medical drugs, is to first listen
to classical music and/or chewing gum and if possible ask your teacher to copy in blue or complete the task with
a grip on your pencil.
Our project is very beneficial to real-life. As for school, improving the level of concentration allows the work to
be completed efficiently and with an increase in productivity. This can lead to better grades and can boost
morale and confidence. It will help in higher grades when more and more work has to be completed quickly.
For example, if you get an essay done a day early, you can take a day to relax and rejuvenate. Also, playing
classical music, chewing gum, using a pencil grip, or using blue paper during standardized testing can improve
student scores, which can lead to improvement in school scores and ratings.
This could be the first step in improving performance and productivity. How can we improve our project?
We could have improved our science fair project in many ways. We could’ve done it once a week on the same
day of the week, as some children have a better morale on Fridays then on Mondays. We could have made sure
that they were wearing the same dress code each day as they could’ve been in more comfortable clothes on one
day than on another. During this experiment we came up with many questions to answer for ourselves. One
question could be, “What would have happened if we gave them more than one of the variables?” We believe it
would increase their score even more, but that question is up to debate. Another question could be, “Could
different textures of clothes help concentration and comfort?” The answer to these questions could further more
improve our studies.
