Cold Pressor Task
Aim
The cold pressor test is done by having the subject submerge their hands in a bucket of cold water to determine cardiovascular changes such as blood pressure and heart rate. For this experiment we wanted to know how long participant can keep their feet in the bucket of ice water before they experience any pain while looking at neutral and positive pictures and also rate the intensity of their pain. For this reason we hypothesized that, if participant submerged their feet in a bucket of water while looking at the positive stimulus, it would take them a long time to experience pain and will keep their feet in the bucket of ice for a long time than when participant are looking the neutral stimuli while they have their feet in the bucket of ice, we also hypothesized that heart rate will increase the longer participant keep their feet in the ice water. The null hypotheses was that, if participant submerge their feet in a bucket of water while looking at positive stimulus, it would take them the same amount of time to experience pain as when they are looking at the neutral stimulus and that heart rate will stay the same throughout the experiment
Method
Participants, Design and Variable
Participants in this study were 7 from biological psychology lab section 2. Participants were between the ages of 19-23years old and there was not requirement to participate in this study except to be enrolled on biological psychology lab. All participants (within subject) served in all level of the independent variable which was neutral and positive stimuli/pictures. While participant look at either the positive or the neutral stimuli with their right feet submerged in the bucket of ice water, we measured time to pain, time it took for participant to take their feet out of the water. Also while doing this, we measured basal heart rate and measured heart rate every 30seconds while participant had their feet in the bucket

    The homogenates provided were made by homogenizing tissues in a sucrose phosphate buffer in a 1:20 ratio. The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4, 0.8, 1.2, 1.6, 2.0 mg/ml of bovine serum were used to determine absorbance with a spectrophotometer. Two additional samples were made; one was blank and the other was for the specific homogenate sample. Then 3 microliters of bradford assay reagent, which indicates the amount of protein present by color, was added to all samples. The spectrophotometer was zeroed at 595 nm. A standard curve was made with the different absorbencies and concentrations. After the linear equation was formed, the unknown sample concentration was determined using the standard curve equation. A Gel Electrophoresis was used to perform a qualitative analysis. The use of 5 microliters of the homogenate was heated to 80 degrees Celsius. Then the homogenate was transferred to a 2-microliter-protein gel sample buffer. Samples loaded on to the gel was run at 100 v and stained with comassie blue; observations were made next lab.

    In this laboratory experiment, our control was the Daphnia that gets spring water, whereas the drugs were the independent variable and the heart rate was the dependable variable. The first step our group did was to place the Daphnia into a clean depression slide. Next, we added a small drop of the spring water and put a cover slip over the slide. Then, we waited for one minute prior to placing the slide on the microscope in order to allow time for either solution or the drug to take its effect. After we put the slide on the microscope, we located the heart of Daphnia and counted its heartbeats while the other member kept time for each three 10-second trials. We recorded our data and calculated the average heart rates of three trials we found during the experiment. Afterwards, we calculated the average 60-second heart rates by multiplying the averages of our 10-second heart rates by 6. These procedures were repeated with the rest of solutions as well, including caffeine, aspirin, alcohol, sleep-aid, and…

    Observations: The color changing process took longer than we had expected. We observed that after putting the penny in the beaker, the zinc powder surround the penny, which helped it changed its color. We couldn’t complete the experiment so when we took the penny from the beaker, the change in the color wasn’t completed. There were some dark spots and some light parts.…

    The overall goal of experiment four was to determine the identity of unknown cations presented to the student. But in order to know the identity of these unknowns, in part 1, Ag+, Pb+, and Hg22+ were presented to the student in aqueous solutions and then precipitated through experimentation. In part 2, the same procedure was enacted to determine which substances precipitated through qualitative analysis. Solubility rules were also a major theme as solubility is important in determining whether a reaction will produce a precipitate.…

    The purpose of the lab was to see how exercise affects homeostasis by measuring a person’s heartbeat, breathing rate, and sweat while they were exercising. The hypothesis I made was, if the volunteer starts to exercise, then the body will react by quickening the heart and breath rate as well as sweating to keep homeostasis in the body, therefore exercise does affect homeostasis. During the experiment there was some major observations that made the answer to the question clear. As the volunteer exercised the body tried to keep its levels normals by quickening the volunteer’s heart and breath rate. The volunteer’s receptors also sensed that as the volunteer was exercising their body temperature was getting higher so the control system told the…

    Throughout the experiment, female's heart rate as been higher than that of the males. 1 minute of the exercise the female's heart rate had dropped from 15 betas per 6 seconds to 13 beats per 6 seconds. The males had dropped from 13 to 11.5. After 2 minutes the females Heart rate continued this trend of dramatic decrease whereas the males only dropped by 0.5 of a beat per 6 seconds. This is when the females heart rate is at its closest to the males, quite suddenly as the graph shows the female heart rate stops decreasing at such a heavy rate as before and only decreases 0.12 of a heart beat per 6 seconds or 1.2 beats per minute. The males heart rate decreases by a further 1 beat per 6 seconds, to 10 beats per 6 seconds. At 4 and 5 minutes both genders heart rate start to level off to their resting heart rate, though not actually getting there.…

    Are people more sensitive to cold water on their dominant hand or non-dominant hand? If a person sticks their hand in cold water, then their dominant hand will be able to withstand cold the longest. To conduct the experiment two bowls of the same size were filled: one with room temperature water and one with cold water (adding lots of ice). After this was done, each participant put both hands in each bowl (one at a time). The time was recorded how long each participants had each hand in each bowl. The average time of each category was found (non-dominant hand in room temperature water, dominant hand in room temperature water, non-dominant hand in cold water, and dominant hand in cold water). The Independent Variable was participants putting their hands in cold water. The dependent variable was the time the hands were kept in the water. The control group was the time the hands were kept in room temperature water. All of the constant variables were: where the water came from (faucet), where the experiment took place…

    Everything was accurate, sterile, and conducted in the most professional way possible. The only way that the study could have been conducted better is if the sample group of 100 participants could have been increased to possibly 150, 200, or even 300 participants for better accuracy inferencing the population parameter. Additionally, I feel that the experimental study could have been directed in several different ways. For instance, it could have been an experimental lab that measures heart beat in emotions such as excitement, sadness, arousal, and more. The research could have also been completed with the participant in the same manner by Markov, Solonin, and Bojko had completed. In attempting this study, it would be more of a way to either add evidence to support or reject their results. This experimental lab could also work when trying to see how neutral and stressful visuals or auditory stimuli could affect an individual’s heart rate. This experimental research could be taken in many ways for the good of the human race’s delicate and crucial organ, the magnificent heart. All in all, the experimental lab results in “beats for Life” show that an individual's environment can have a significant impact to his or her heart rate in the short term, as well as heart health in the…

    In unit 7.3 the experiment tested the ability of lactase to specifically bind and interact with lactose compared to maltose. In unit 7.4 the experiment tested the role, if any, that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose, lactose will separate into galactose and glucose, as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions, and will not work.…

    Aim:The aim of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise, we measure the breathing rate before physical activity by counting the number of breaths in 10 seconds, and then perform 5 minutes of each level of exercise and counting the number of breaths at every level. There will be three levels of physical activity, light, mild and heavy.…
