Problem

What is the High Blood Pressure?

Hyphothesis

I think if we drink Coca Cola our blood pressure will increase.I think a healthy adult person need to have 120mmHg and if it have more than 120 mmHg it considered as High Blood Pressure. And also if a person have lower than 80 mmHg it considered low blood pressure.

What is blood pressure?

Blood is carried from the heart to all parts of your body in vessels called arteries. Blood pressure is the force of the blood pushing against the walls of the arteries. Each time the heart beats, it pumps out blood into the arteries. Your blood pressure is at its highest when the heart beats, pumping the blood. This is called systolic pressure. When the heart is at rest, between beats, your blood pressure falls. This is the diastolic pressure. Blood pressure changes during the day. It is lowest as you sleep and rises when you get up. It also can rise when you are excited, nervous, or active.

Material



We Need the Following





Person




Blood Pressure Monitor

Pencil

Observation





Caffeine Drinks



Procedure

1. First we have drinks that contain caffeine and a blood pressure monitor.

2. Second, we will drink the drinks that contain caffeine and wait like 1 minute to check our blood pressure with the blood pressure monitor.

3. we will write down the caffeine we drinks.
-Statistic of the drinks that contain caffeine

- 12 oz Coca Cola 34 mg
-12 oz Pepsi 38 mg
-12 oz 7-up 0 mg
-12 oz Iced Tea 70 mg
-8 oz Chocolate Milk 5 mg

Our Experiment Result......

Our Result for the experiment is that the Coca Cola does raise the blood pressure. The blood pressure can be raise by many ways. If you drink like a can of Coca Cola, your blood pressure will increase 10~20. I think I can raise my blood pressure by drinking one can of soda. And we have found out that if a person drink one can of Coca Cola does affect the blood pressure.

The conclusion of this whole project is that the blood pressure can be raise by a can of Coca Cola. We have used some materials to help us do our Experiment: Can of Coca Cola, Blood pressure monitor. First I told Zhuo bin to drink the can of Coca Cola, Second we have waited 2 minute to let the can of Coca Cola go down to our stomach and last we have used the person blood pressure and we tested that the Can of Coca Cola did raise the person Blood pressure. We did this experiment on china town by Dr. Wong
