I developed my experiment because I like to exercise. The experiment was also developed because I like to learn how the brain works and if exercise would actually increase you memory. This experiment tested the hypothesis because of after the exercise every one took the test improved on it. This experiment also proved that the hypothesis was correct because the hypotheses of this experiment is that exercise will increase memory because of the human body pumps more blood to the brain when exercising. When there is more blood pumping to the brain

Tell volunteers to memorize as much as they can in 30 seconds.
6. Set timer for 30 seconds
7. Take towel of then start timer
8. When timer runs out put towel back on items
9. Then ask them to wright down how many items they remember
10. Then take their papers when there finished writing the items down.
11. Have the volunteers exercise for 10 min.
12. Have them retake the test
13. See how much higher there score was on the test than before.
The data of this experiment supports the hypotheses because of after the exercise the scores of the volunteers for the experiment improved. The hypotheses for this experiment was after the exercise the scores on the memory test would improve because of when exercising the human body will increase its heart rate pumping more blood to the brain. This would mean that there is more oxygen running to your brain. There were 2 trials for this experiment one before exercising and one after exercising. The first trial was before exercising which the scores for the test were average of the scores were 11.25 on the 2nd trial of this experiment the average score of this trial was 16.25. Both trial 1 and 2 supports my hypothesis because there score was higher than their score before the

That would be a flaw for this experiment because of They would have not scored as high if they didn’t remember it.
The data shows that there was an increase in scores on the memory test. Something that was learned in this experiment was that exercise can increase your memorization.
Can exercise increase memorization. During this experiment everyone that exercised increased on the memory test by an average of 5 points improved. The reason that the volunteers improved on the test were because of when exercising the human body the heart pumps more blood to the brain. When the heart pumps more blood to the brain there is more oxygen getting to the brain making it work better. The changes that would be changed the next time this experiment the next time this was conducted would be that there would be a change in the items on the table for the test before and after the exercise. After the experiment the next step that would be investigated would be how the brain is able to increase its memory after
Within the target site of the experiment, researchers wanted to answer their hypothesis; hypothesis was that increased police
Over a three week period a test subject was instructed to come to the exercise physiology lab once a week. The purpose of the first week was to determine the baseline test data for the participant. During this first week, the subject was asked how many hours of sleep they had gotten the night before and how much they weighed. The subject was then instructed to put on a heart monitor and wear an O2 apparatus and begin running on a treadmill. This treadmill was set at zero incline for the beginning of the run until three minutes had passed. At the three minute mark the incline increased by 2.5%. After this the incline was continuously increased by 2.5% every two minutes. During this process, the VO2 and RER exchange rate of the subject was being tracked through the O2 apparatus. Their heart rate was recorded every 15 seconds. In addition, the subject was asked their perceived exertion at every increase in incline. The subject continued to run until they could not run anymore, at this time they would hop off the treadmill.
Learning is one of the things that help us survive. Darwin taught us that learning is the survival mechanism that we use to survive in our ever-changing environments. Our brains are designed to learn. They are plastic, meaning they can adapt, change and grow. In our brains there are neurotransmitters, and neurotrophins. They both have a role in turning different circuits on off, and getting different signals to different parts of our bodies. Some neurotrophins are called factory, and one of those is BDNF, or brain-derived neurotrophic factor. This chemical has been called, fertilizer for neurons. Exercise has been shown to increase BDNF leve...
Another confound that may impact the results of this study could be the testing effect. Repeated testing may lead to better or worse performance. Changes in performance on the test may be due to prior experience with the test and not to the independent variable. In addition, repeated testing fatigues the subjects, and their performance declines as a result (Jackson, 2012). Because the professor is interested in determining if the implementation of weekly quizzes would improve test scores, an experimenter and/or an instrumentation effect may also affect results.
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
A study done at the American College of Sports Medicine reported that “fourth and fifth grade students who ran around and otherwise exercised vigorously for at least 10 minutes before a math test scored higher than children who sat quietly before an exam.” Physical activity is said to improve much more than physical health, and is known for the improving one’s memory and focus. Another article mentioned that physically active students tend to outperform their peers in the classroom who are not active. The article also mentions that “physically active students have larger brain volumes in the basal ganglia and hippocampus, areas associated with cognitive control and memory (Medical News, 1).” Exercise has been known to help students concentrate better in their classes, and accomplish their homework later
In order to have a successful, reliable experiment you need sufficient data and evidence, reliable research, variables to test and a follow – up experiment. There are several types of variables you need to do an experiment. An independent variable is the manipulated experimental factor that is changed to see what the effects are. A dependent variable is the outcome. This factor can change in an experiment in reaction to the changes in the independent variable. An experimental group is the group of participants that are exposed to the change that the independent variable represents. The control group is participants who are treated in the same way as the experimental group except for the manipulated factor which is the independent variable (King 24). Proper data, evidence and research is also needed so the experiment turns out correctly and you know what you are testing. A follow – up experiment is not required, however it helps the validity of the conclusion of the experiment. Validity is “the soundness of the conclusions that a researcher draws from an experiment” (King 25). Conducting a follow – up experiment will help researchers and people alike see if the experiment worked properly, continues to help people and see how participants are doing after the experiment is over.
In the article, “The Critical Importance of Retrieval For Learning” the researchers were studying human learning and memory by presenting people with information to be learned in a study period and testing them on the information that they were told to learn in order to see what they were able to retain. They also pointed out that retrieval of information in a test, is considered a neutral event because it does not produce learning. Researchers were trying to find a correlation between the speed of something being learned and the rate at which it is forgotten
In order to avoid the physical effects of aging, it is suggested that individuals engage in frequent exercise. Doing so will enhance muscular and cardiac ability, and will reduce one’s risk of various forms of heart disease and obesity (Myers & DeWall, 2016). Due to an increase in oxygen flow, exercise may also stimulate neurogenesis (Myers & Dewall, 2016), a process that promotes growth in hippocampal nerve cells that may result in an improved ability to retain memory. In relation to physical exercise, it is also suggested that adults in middle or late adulthood participate in “brain training” exercises, which have shown to make small improvements in one’s depreciating cognitive development. As a result of the brain’s neural plasticity, such brain exercises have the potential to enhance an individual’s ability to complete control tasks, while other research indicates that it can result in an overall sharpness of the mind (Myers & DeWall, 2016). Despite the onset of an aging mind and body that is characteristic of adulthood, exercise of all forms can induce positive outcomes for older individuals in both their physical and cognitive
Understanding the connection between physical activity and the brain is essential to demonstrate how influential exercise can be for individuals thought process. Exercising causes the blood in ones body to flow more quickly to the brain resulting in a higher supply of oxygen. With a greater amount of oxygen, the neurotransmitters are synthesized while triggering the neural activities that regulate a persons’ mood (Baumann). When being physically active, our metabolism turns on our hormonal processes contributing to a positive mentality. Having more oxygen and nutrients in the brain provides more sufficient ways of thinking as well as motivation. Students have cited that they have no time to fit a work out into their busy schedules as college students. Also, many have
Gum, not only a fun thing to chew whenever we feel, may actually be helping us in school. The experiment is all about how the brain remembers words. But in this experiment, I am testing if gum actually helps us remember a paragraph of words. The variable that is changing is the flavor of gum. It is being changed to see if one helps more than another flavor. One thing I am keeping the same is the paragraph being memorized.
They are trying to get a perspective on how sleep effects a person’s memory and learning capability. Researchers will find out if an increase in sleep will improve the function of memory and learning. Referring to the hypothesis, this will be a positive correlation since memory and learning will improve as sleep improves. This will be a between subjects design because this study consists of four groups that is being tested by different factors which would be designated sleeping times in this
Past studies in both animals and humans have proposed that length of exercise is associated with better cognitive function (Colcombe & Kramer, 2003; Holmes, Galea, Mistlberger, & Kempermann, 2004). However, other studies have proposed that only small doses of exercise are needed to see significant health benefits (Beddhu, Wei, Marcus, Chonchol, & Greene, 2015; Hupin et al., 2015). Past studies have also found that shorter duration high-intensity regimens are also beneficial in regard to cardiovascular and metabolic function, musculoskeletal benefits and cognitive performance. (Gibala et al., 2006; Gillen, 2012; May et al.,
It may have, however, done the opposite. In trial one, only forty percent of the scores went up (See Trial 1 Chart), in trial two, only thirty percent of the scores got better (See Trial 2 Chart), and, in trial three, only twenty percent of the participants’ scores increased (See Trial 3 Chart). This means, that on average, only twenty-eight percent of the participants did better on their memory test while using the cinnamon scent (See Chart Section 4). Obviously, this majority proves that the participants most often did their best without the help of the cinnamon.
It even helps you test better according to a the Mayo Health Clinic’s statement: “Those who had exercised during the preceding month but not on the day of testing generally did better than those who had been sedentary, but did not perform nearly as well as those who had worked out that morning.” Another internal effect of working out is muscles receiving more blood, higher VO2 level, and helping maintain bone mass. The fitter a person is, the more efficiently their heart works therefore, blood pressure decreases and new healthy blood vessels form. Exercising expands a person’s life cycle because the more someone workouts, the healthier they are. Furthermore, the brain is one part that no one would think exercising has anything to do with, but it’s the main one that is affected. Exercising results in increased brain flow which helps the brain function more efficiently. Also, new brain cells are formed that help boost memory and learning. A number of neurotransmitters are triggered, these are what controls a person’s mood; this is how exercise prevents depression. Working out improves development of neurons, production of nerve protecting compounds, and can reverse brain and muscle decay. There are various positive internal effects that exercise has on people’s
