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
Over a three week period a test subject was instructed to come to the exercise physiology lab once a week. The purpose of the first week was to determine the baseline test data for the participant. During this first week, the subject was asked how many hours of sleep they had gotten the night before and how much they weighed. The subject was then instructed to put on a heart monitor and wear an O2 apparatus and begin running on a treadmill. This treadmill was set at zero incline for the beginning of the run until three minutes had passed. At the three minute mark the incline increased by 2.5%. After this the incline was continuously increased by 2.5% every two minutes. During this process, the VO2 and RER exchange rate of the subject was being tracked through the O2 apparatus. Their heart rate was recorded every 15 seconds. In addition, the subject was asked their perceived exertion at every increase in incline. The subject continued to run until they could not run anymore, at this time they would hop off the treadmill.
The purpose of this experiment was to identify which brand of mint gum holds its flavor the longest. The four brands I chose were Orbit, Trident, Ice Breakers, and Wrigley's Doublemint My hypothesis was that Trident brand would last the longest and Wrigley's Doublemint would last the shortest. I did not use any people in my test. I chewed the same amount of gum at a time and the gum was all the same flavor, mint. All the gum was bought at the same time from the same store. I chewed the four brands of gums between periods of time. When chewing, I timed myself with a stopwatch. When I believed the gum ran out of flavor, I stopped the timmer and recorded the time. My hypothesis was incorrect. Instead of Trident, Orbit lasted the longest. However
For this experiment the null hypothesis is that the intensity of the step rate test (High and Low) has no effect on the persons’ heart rate and recovery time. While the alternate hypothesis is that the intensity of the step rate test (High and Low) has an effect on the persons’ heart rate and recovery time.
Blood pressure is measured by two pressures; the systolic and diastolic. The systolic pressure, the top number, is the pressure in the arteries when the heart contracts. The diastolic pressure, the bottom number, measures the pressure between heartbeats. A normal blood pressure is when the systolic pressure is less than 120mmHg and Diastolic pressure is less than 80mmHg. Hypertension is diagnosed when the systolic pressure is greater than 140mmHg and the diastolic pressure is greater than 90mmHg. The physician may also ask about medical history, family history, life style habits, and medication use that could also contribute to hypertension
For example: if hypertension goes untreated then it could potentially lead to stroke, heart attacks, and untimely death. Early detection and improve patient outcomes by educating the patient on lifestyles changes and effective drug treatment. It is important for the patient to alter their eating habits, as well as their sedentary lifestyles and monitor their blood pressure levels. Feasible and affordable screening approved by the patient is also important: for example, electronic monitoring can make it easier for the patient to obtain their levels without causing harm and cost effective.

The tennis ball is the constant variable factor (the variable that is kept the same, to make the investigation valid). The ball will dropped from increasing heights (cm-25, 50, 75,100,125,150,175,200) and the bounce of the ball will be measured. A sample size of 3 results will be taken from each height the ball is dropped. The same investigation will then be repeated, but one of the independent variables will be changed.
The design was a laboratory experiment, which allows the experimenter to establish a cause-effect relationship between the independent and the dependent variable.
In the study, the independent variable, the variable to be manipulated, was the different emotion conditions of the experimenter, which was myself. I had to give three different emotion conditions, which are smile, neutral and frown. Moreover, the dependent variable, the variable to be measured, of the study was the degree of emotional response of the strangers that were approached. In addition, the study might include confounding variable, which are the cultural background of the strangers, and the mood of strangers of the time. The confounding variables should be controlled as they might affect the dependent variable. The operation of the experiment was I walk up to a stranger and put on different emotions on my face, and observe the response of the stranger.
Our independent variable is one piece of the type of chewing gum we will be giving each of our test groups: flavorless, mint, or fruit flavor are the three types. We are using three different flavors of chewing gum, including one with no flavor, to see if the increase in intellect has anything to do with the taste of the gum rather than just the movement of the jaw. We will use the results of each flavour to see if maybe a certain flavor s...
The key priority for nursing care with this patient is her learning disabilities and the potential communication barriers that may occur. The patient’s hypertension is well controlled with medication; for these reasons I will focus this assignment around communication barriers with people with learning disabilities, and the importance of good communication between the multi-disciplinary team within the unit. I will also explore any issues with consenting to the procedure, as it is imperative that the patient is fully aware of the procedure and understands the possible risks and complications. I introduced myself to the patient stating that I was a student nurse and gained verbal consent to carry on with the assessment, as a student nurse you must respect patients wishes at all times, if they do not wish for a student to carry out the assessment this must be respected, the patient wishes out way the need for the student to gain experience (NMC 2005).... ...

The experimental study is whereby the effect of television in comparison to the children’s weight was being measured. This difference is being measured with regard to the changes that would be expected after a child plays a physically engaging game within a period of time then the weight is compared to the weight they had before the exercise. The experiment aimed at reducing the weight of children thus the weight of the children is the independent variable in this experiment. The dependent variable in this experiment is the extent to which the children were exposed to the television exercise in a bid to determine their weight.
There were 2 trials for this experiment one before exercising and one after exercising. The first trial was before exercising which the scores for the test were average of the scores were 11.25 on the 2nd trial of this experiment the average score of this trial was 16.25. Both trial 1 and 2 supports my hypothesis because there score was higher than their score before the
Independent variables: The temperature of hcl gas will be decreased and increased throughout the experiment.
One Third of the US population suffers from high blood pressure, or hypertension. If you suffer from high blood pressure it may feel hopeless, because there is currently no cure. Chiropractic Care, however, can help. If you are looking for a natural way to lower your blood pressure chiropractic care may be the perfect option for you.
