First Steps Research Question How does energy consumed from
energy drinks compare to energy consumed from a healthy meal and
how does it affect ones performance in a physical activity?
Hypothesis If a person consumes energy from a healthy meal as
opposed to an energy drink, then their performance in a given
physical activity will be better due to an increased number of
nutrients and overall greater energy gained from the healthy food.
An energy drink may supply caffeine and sugar, but the burst of
energy is short-lived and insubstantial in comparison to the energy
received from a healthy meal. We hypothesize that an energy drink
is actually detrimental to physical activity due to the harmful
chemicals and ingredients within it.

Describe experiment or research plan Biology For our experiment
the test subjects are either eating a healthy well balanced meal
for breakfast, no breakfast at all, or having an energy drink. We
are seeing how these different meal choices affect the body's
energy. The energy is created through a process called Aerobic
Respiration. This is where energy is released in cells from the
breakdown of food/drink consumed. The energy is released in the
form of ATP, the usable source of energy for life processes.
Chemistry The glucose that we obtained from the energy drink and
healthy breakfast are oxidized within the body through complex
chemical reactions. This process is known as Metabolism and can be
seen in the chemical formula: C 6 H 12 O 6 + 6O 2 6CO 2 +6H 2 O In
our bodies, this reaction produces carbon dioxide, water, and
energy which our cells can use. Physics We calculated the average
velocity and kinetic energy exerted through the physical
activities.

Procedure Materials: Stopwatch, Meter stick, Healthy breakfast
(Toast, Apple, Peanut Butter, eggs), Energy Drink (Kickstart) 1.In
the morning before school, eat designated meal for day (healthy,
energy drink, or nothing) 2.Measure distance of court that will be
ran and mass of the runners 3.Run around court, stopping at each
corner to do 10 sit-ups at the first corner, 10 push-ups at the
second, and 10 jumping jacks at the third, and then run to the
fourth. 4.Have a timer-keeper record the tie to perform each
individual activity and then record the information in a data
table. 5.Calculate the average time to complete the physical
activity for each day (healthy, energy drink, nothing) and then
calculate average velocity during running and kinetic energy
exerted through motion 6.Calculate glucose intake and output of
energy, and then conclude whether the different breakfast choices
affected physical activity.

Calculated Data Average velocity can be found through total
distance divided by total time. Kinetic Energy can be found using
the average velocity in the equation KE = (mass)(velocity)^2 For
example, The average velocity and kinetic energy of Jordans
breakfast run time would be worked out as such: Average Velocity =
Distance/Time Time = 2.7s + 2.89s + 2.89s + 3.54s = 12.02s,
Distance = 6m + 9m + 9m + 6m = 30m 30m/12.02s = 2.49 m/s The
average kinetic energy would be KE = (mass)(velocity)^2 Velocity =
2.49 m/s, Mass = 54 kg KE = (54)(2.49)^2 Average KE = 167.40 J

Final analysis and conclusions We expected that when the test
subjects ate a healthy breakfast that the time it would take for
them to complete the various physical activities would be
significantly shorter than the times of the test subjects who did
not have breakfast or had an energy drink. We found that during the
experiment, the average time for all people to complete the
physical activity after a healthy breakfast was the fastest by a
miniscule.46 seconds over no breakfast, and that no breakfast was
1.69 seconds faster than energy drinks. This supports our original
hypothesis, as breakfast resulted in better, faster physical
performance than no breakfast, which resulted in better physical
performance than an energy drink. EventAverage Time

Unexpected Outcomes Unexpected outcomes that were found in the
conclusion of the experiment were: The energy drink resulted in a
slightly higher kinetic and average velocity than that of the no
breakfast. Jordans longest time was associated with a healthy
breakfast rather than an energy drink, which was expected. Mikaelas
time when consuming a healthy breakfast was longer than the time
when consuming no breakfast. Reasons for the unexpected outcomes
could be due to consumption of water, weight of clothing and shoes,
sleep hours, inconsistent timing, and amounts of the designated
breakfast consumed.
Slide 13
Explain Your Findings Overall, our average times for completing
each trial confirmed our hypothesis. We completed the course in the
least amount of time when we ate a healthy breakfast, and we took
the most time when we drank an energy drink. This is because our
body was able to gain and retain more energy from a healthy
breakfast as opposed to an energy drink or no breakfast at all.
Although energy drinks give you a burst of energy, the caffeine is
not long lasting. The chemicals used will eventually leave you more
tired than before.
Slide 14
Different Sciences and the Conclusion Biology When the meal is
consumed, our bodies break down what is consumed and transform it
into usable energy (ATP). When nothing is consumed, the body has
little to no usable energy, and thus moves slower. The energy drink
only provided us with a quickly used form of energy, so when the
trials came, our bodies generally moved slower. Because the healthy
breakfast was the most substantial, it provided us with the longest
lasting energy. Chemistry When we consumed a healthy breakfast, our
bodies were able to metabolize the most energy through various
chemical reactions, giving us the most readily available energy
when compared to eating no breakfast, or drinking an energy drink.
When we drank an energy drink, we gained a large amount of energy
but only for a short time. This energy was metabolized much faster
and mostly burned off by the time we completed the trials. When we
ate no breakfast, we only had the little energy left from previous
meals. These all help confirm our hypothesis. Physics When we
consume a meal, the energy is then converted and used up through
movement and activity. The energy consumed through movement can be
calculated through the equations average velocity and kinetic
energy. The calculations for kinetic energy did not completely
confirm our hypothesis, as the kinetic energy consumed with an
energy drink was higher than no breakfast at all. A healthy
breakfast, however, used the most kinetic energy, which confirms
our hypothesis.
