Your paragraph here

Problem: Can I improve my brain health if I get at least 45 minutes of physical activity daily?Research: -the recommended time of physical activity daily to increase brain health is 60 minutes, 30, minutes, or 20 minutes (45 minutes is in the middle)-exercising daily releases neurotrophic factors like BDNF which stimulates the growth of new neurons-exercising daily improves information processing and memory functions Hypothisis: If I exercise for atleast 45 minutes a day then my brain health and testing scores will improve

Experiment:Materials: pool, bathing suit, jumprope, bike, trapoline, tennis shoes, fieldhockey stick, ball, field, goal, and uniformProcedure: Monday~ 1. ride bike (30 min) 2. get on trampoline (15 min)Tuesday~ 1. walk around (10 min) 2. ride bike (20 min) 3. get on trampoline (15 min)Wednesday~ 1. Jump on trampoline (30 min) 2. Ride bike (15 min)Thursday~ 1. Field hockey practice (1 hr 30 min)Friday~ 1. Swim laps (1 hr)Saturday~ 1. Ride Bike (25 min) 2. Practice Field hockey (15 min) 3. Jumprope (5 min)Sunday~ 1.Swim laps (1 hr) 2. Field Hockey (1 hr)Dont forget: Take brai tests every 3-4 days and repeat steps for 13 days

Analysis:On my data table I notice that seven out of the thirteen testing days I exercised for more than forty-five minutes. Another notice I had was that five out of thirteen testing days I exercised for less than my goal of forty-five minutes. I notice that in my memory data I mostly stayed on the levels nine and eleven. Another notice I have about my memory data is that the last memory test was when I reached my highest overall level. I notice in my fact recall that at the end instead of increasing my score from the first test my score actually went down. I also notice in my fact recall that instead of my scores gradually increasing or stating consistent they actually jumped up and down drastically. In my data I also noticed that there were trends in my data and testing scores. The first pattern is that the first day I collected data I exercised more than forty-five minutes and got the highest fact recall score that testing day. Another trend/ pattern i noticed was that the next testing day I went down in score. I think this is because I only exercised for fifteen minutes the night before. As for my memory testing data I was distracted for about half of the tests (mondays) and that was also when I reached a lower level. The last trend or pattern is that when I wasn't distracted or tired I could focus better and got higher testing levels on my memory testing.

How Does Physical Activity Affect Your Brain?

OverviewPhysical activity can have lots of different effects on the adolescent brain. Main Idea 1: Exercising daily can improve the your brain's reticular activating system’s ability to filter out distractions and unnecessary factors of a problem or situation. This means in other words that exercising daily can improve your brain's ability to stay focused and concentrate on one thing.-Strength training helps your focus because it involves focus [4]-Exercising in the morning can improve concentration because it can clear your brain of distracting thoughts so you are ready to take on problems of the day [5]-Exercise increases blood flow to your brain making it easier for you to focus throughout the day [6]Main Idea 2: Exercising daily can help the brain deal with stress and depression better.-Exercise can improve mental health health by helping the brain cope better with stress [7]-Physical activity can help bump up your brain’s overall production of endorphins (feel good hormones) [8]-Exercise promotes reduced inflammation and new activity patterns that promote feelings of calm and well being [9]


Conclusion:My hypothesis was “If I exercise for at least 45 minutes daily then my brain health will increase.” My hypothesis was rejected. My hypothesis was rejected because even though my memory levels increased from the beginning my fact recall did not. My memory data went up from the first test from 11 to 12. My fact recall baseline was 33 correct facts in 1 minute but my last test was only 31 correct facts in 1 minute, therefore my hypothesis was rejected. My problem for this experiment was “can I improve my overall brain health if I get at least 45 minutes of physical activity everyday?”. The answer to my question was “No I cannot improve my overall brain health if I exercise for at least 45 minutes everyday.”. The answer is no because even my memory data improved, my fact recall did not. The reason that my answer is not yes is because both tests did not improve which means my overall brain health did not improve. In my experiment there were a few errors. The 1st main error was that 5 out of the 13 data collection days I did not exercise for at least 45 minutes. The second error was that during testing there were distractions such as talking, papers rustling, and binders zipping and unzipping, etc… Next time if I do this experiment again I would change a few things. The first thing i would change is where I was tested. I would change this because there were distractions this time and if there were not any I could have got more accurate data/results. The second thing I would change is that i would follow my procedure more precisely. If I were continue researching or testing I would like to find out what exercises are most beneficial for improving overall brain health.
