Problem: Why does Thanksgiving make people sleepy?

Hypothesis: (include reasoning and prediction)

The people that ate the most on Thanksgiving will be the sleepiest. When food is ingested, the body immediately starts to break it down and digest it. To do this, the digestive organs need a much larger amount of blood, and energy, than they do when they aren’t digesting anything. The blood usually used by the brain and other muscles will be transferred to digestive organs. Therefore, if a person eats more food, than they will be sleepier.

Data and Observations:

Conclusion: (include information from at least 2 reputable sources and site them)

The data found supports my hypothesis. Person A ate a lot more food, and 3 more rolls than Person B. My hypothesis reasoned that because there would be a large amount of food coming into the body, blood would be taken from other muscles and sent to the digestive system. Also, because Person A ate 3 more rolls than Person B, it can be inferred, that because carbohydrates take a longer time to digest and require more energy, this would be a factor in becoming sleepy. Another reason as to why the more people ate the sleepier they would be is the presence of L-tryptophan in turkey. L-tryptophan is an amino acid that is much needed by the body. It creates a soporific and relaxing state for the body. The more turkey a person eats, the more L-tryptophan they ingest, and the sleepier they will be. The data found very strongly supports and strengthens my hypothesis.
