Narrative of my Energy bar Project
Over 6 basketball practices I evaluated 5 energy bars. On one day I ate nothing to establish my baseline. Each day at 3:00 p.m. I ate my energy bar prior to practice. The way I controlled the external variables was to eat the bar at the same time, and always ate the whole bar. I always made sure to have a regular day at school by getting enough sleep, and eating a normal amount. This experiment took longer than I expected because I had to keep the variables consistent. It took me about a month and a half longer to complete this project because I had to keep the variables consistent. My hypothesis was that the energy bar that tasted the best would be the least effective.
I judged each bar by rating it on a scale of 1-10. I rated the taste, how much energy I felt I got, and how much it relieved my hunger. On day 1 I had a Chocolate Peanut butter bar made by Quaker. It gave me a 4 on taste, 4 on energy, and 4 on how much it relieved my hunger. On the second day I had a Chocolate Chunk Chex Mix bar. It gave me a 5 for taste, 2 on energy, and 3 for how much it relieved my hunger. On the third day of my experiment I had a Pure Protein Chocolate Peanut Butter energy bar. It gave me a 7 for taste, 5 on energy, and 9 for how much it relieved my hunger. On the fourth day I had no energy bar. This was my baseline. I was a little hungry (3) and kind of tired (4). For the fifth day of my experiment I had a Promax Double Fudge Brownie energy bar. It gave it an 8 for taste, 1 on energy, and 9 for how much it relieved my hunger. On the final day of my experiment I had a Supreme Protein Peanut Butter Crunch bar. It gave it a 10 for taste, 6 on energy, and 9 for how much it relieved my hunger.
What I would do differently is try to get my writing work done faster. Also try to get other work done faster so I didn’t have to stay after school and miss the first part of practice. Which if I missed the first part of practice I couldn’t do a recording of data for the day because it wouldn’t be consistent. Overall the Supreme Protein Peanut Butter Crunch bar was the best. It had the highest rating in all categories. My hypothesis was not correct though. This energy bar had the best taste to me, and gave me the most energy.
