	                                    The Effects of Food on Heart Rate

	The circulatory system is a body system in the human body. It includes your heart, kilometers of blood vessels, and blood. Materials are moved through the body. The blood vessels that are a tubular structure, carry blood throughout the body. The blood serves to move oxygen and nutrients. The heart is made of cardiac muscle tissue, and is located behind the breastbone, which is called the sternum. The heart's purpose is to control blood flow, and the blood vessels are arteries, veins, and capillaries. Vessels help carry blood away from the heart. Movements of cells into and out are caused by diffusion, which is where particles spread from where more of it is to where less of it is. The circulatory system is responsible for removing carbon dioxide and other waste products.
	Pulse tells you your beats per minute (bpm). Pulse is basically used as a tool for measure heart rate. Many factors can increase or decrease your heart rate such as stress, exercise, smoking, etc. Heart rate is also increased by theobromine, which is a stimulant found in chocolate and chocolate-flavored foods. Theobromine increases blood pressure, which can be harmful to your health, because it suggests that risks of getting certain threats such as heart disease or stroke are high. Low blood pressure can help defend your body against these threats. Being overweight can cause high blood pressure, because large amounts of body fat force the body to pump faster. So it is recommended to not eat too much food, and maintaining a healthy lifestyle by eating healthy foods. The purpose of our lab is to see how food affects heart rate.
Hypothesis: Our claim is that the food will affect heart rate, because of the amount of salt and sugar.
IV: Food
DV: Heart Rate

Control: Resting Heart Rate (RHR)

Constants:
1. Amount of each type of food
2. Time
3. Heart Rate App

Materials:
Crybaby
Flaming Hot Cheetos
Cotton Candy
Heart Rate App
Triple beam balance


					        Procedure:

1. Find the resting heart rate for all 6 participants and record the data on the data table.
2. Have each participant eat 10 grams of crybaby.
3. Take heart rate after 90 seconds for each participant and record it on the data table.
4. Wait 3 minutes before testing Cheetos
5. Repeat steps 1-3 for Cheetos
6. Wait 3 minutes before testing cotton candy
7. Repeat steps 1-3 for cotton candy

					    Data Analysis:

   1. Food affects heart rate by causing it to spike or decrease
     2. Patterns that are shown in our graph is that most of our table mates' heart rate increased after eating Cheetos
     3. Yes there are outliers in our data, because Kevin's resting heart rate went from 71 to 75 in trial 1, then skyrocketed all the way to 85 in trial 2. I think this is because Kevin had a fever that day when we took his heart rate for trial 2, so his heart rate went up because of his sickness.
     4.  My hypothesis was correct, because all of the participants' heart rate was increased or decreased after eating. If I could revise my hypothesis I would write, “I think that after consuming food, the participants' heart rate would either spike or be lowered, because of the amount of salt and sugar.

Conclusion:

	Heart rate can be spiked after eating certain foods or be lowered. Heart rate can be increased or decreased, because based on my data table, it shows Shania's resting heart rate going from 91 to 83 in trial 1 of eating Flaming Hot Cheetos and in trial 2 her heart rate was 86. Also, after eating cotton candy, Kayla's resting heart rate rose from 89 to 98. This data shows that heart rate can spike or decrease, because based on this data Kayla's heart rate spiked, and Shania's heart was lowered, therefore supporting my claim. A human error is that Kevin's resting heart rate went from 71 to 85 in trial 2. This probably was due to his fever, because a fever can cause your heart rate to go up. My data is reliable, because we my table and I made sure that each participant has a certain amount of food, and set the timer to measure their heart rate. We also told them not to do any sort of movement, so our data can be reliable.
