Blood Pressure Experiment

Introduction In our experiment, we are testing the affects sodium has on our blood pressure. If increased amounts of sodium are consumed, will that increase blood pressure? The hypothesis is when more sodium is introduced and consumed, then the person's blood pressure will increase, when blood pressure is a function of sodium. Our independent variable is different amounts of sodium introduced to noodles. We are using different amounts of sodium added which would be: 1 gram, 3 grams, 5 grams, and 7 grams. Our dependent variable is the diastolic and systolic readings will increase. The control in our experiment is our test subjects eating no noodles. The constants would be the same person taking the blood pressure, same three guys eating the food, the test subjects are all 17, and the same food with added sodium fed to each person in each trial. In this experiment, the first step we would took in this was acquiring three guys that are all 17 . One person would get high amounts of sodium, another person would have medium, and one person with very low amounts of sodium, our control. Then, we would take each person blood pressure and record it. After that we would give each person their assigned amount of sodium. Lastly, we would take the blood pressure of each person after they ate the different sodium foods. We will do this for two weeks three times a week and record our data and at the end compare our data. The materials we will need …show more content…

First off, we need to know how to properly take someone's blood pressure. We will need to make sure we know how to correctly take it so we do not cause pain or hurt someone's arm. Also, it could potentially be dangerous to the test subject if we give them excessive amounts of sodium that could cause health problems. We will have a health science teacher observe us taking blood pressure, so we know we are doing it correctly and will not hurt
