The effect of exercise on clothespin squeezing rate
Hypothesis:
•A person will be able to squeeze a clothespin more times in a minute if the person exercises first.
Methods:
•Independent variable- amount of exercise
•Dependent variable- number of clothespin squeezes per minute
•Controlled variable- amount of time exercising and resting, number of trials, type of exercise, same type of clothespin , intensity of the exercise, and the age of test subjects
Materials:
•Clothespins
•Timer/stopwatch
•Paper and pencil
•Test subjects(students)
Procedure:
1.There will be two groups, the control and experimental groups. Each group will have the same amount of participants with equal numbers of boys and girls. The first group will be the control group(rest). The second group will be the experimental group(exercise).
2.The control group will rest for two minutes and the experimental group will exercise for two minutes. The experimental group will exercise by doing jumping jacks.
3.After 2 minutes, each participant in both groups will get a clothespin. Each person is going to count the maximum number of times they can squeeze the clothespin in one minute.
4.Repeat steps 2 and 3 for two more trials.
5.Data will be collected and recorded in the trials section of the data table.

The reason why is that exercising gets your blood pumping which brings more oxygen to your muscles. According to table #1, it can be seen that most of the numbers under the difference column are positive which means that these people’s squeezing rate increased when they exercised first. Based on graph #1, you can see that more people increased by the height of the bar. Both the table and the graph support that if a person exercises first , he/she will be able to squeeze a clothespin more times in a minute than a person who rests
In this lab, we explored the theory of maximal oxygen consumption. “Maximal oxygen uptake (VO2max) is defined as the highest rate at which oxygen can be taken up and utilized by the body during severe exercise” (Bassett and Howley, 2000). VO2max is measured in millimeters of O2 consumed per kilogram of body weight per min (ml/kg/min). It is commonly known as a good way to determine a subject’s cardio-respiratory endurance and aerobic fitness level. Two people whom are given the same aerobic task (can both be considered “fit”) however, the more fit individual can consume more oxygen to produce enough energy to sustain higher, intense work loads during exercise. The purpose of this lab experiment was performed to determine the VO2max results of a trained vs. an untrained participant to see who was more fit.
A sample of children ranging from 4 to 13 years old are going to be asked to watch a Rainbow Brite video. The children will be randomly picked from a childcare center. To ensure that the children are going to be randomly assigned, the children will range in different age groups. The first group will consist of 4, 6, and 8 year olds. The second group will consist of 10,12, and 14 year olds. It would have to be a field experiment because you have to go out and collect the data.
At least one hundred subjects would be divided evenly into two groups, one of which would be a control group of persons
Our project is how to train goldfish. We want to test the behavior of the fish. In the other we will just feed them. The constants are the tank, the amount of the goldfish, the feeding time, the rocks, and the days we clean the tank. In the experimental group we will have two fish and every time we feed them we will have two fish and every time we feed them we will ring a bell for 7-seconds. In the control group, we just feed the fish. We will condition the fish who know when they are being feed. In conclusion, our science fair project is
n hypothesis of the experiment is that the group containing four members will perform better than the group containing two members. This is the foundation from which we have conducted our experiment.

* Age of the person exercising * level of fitness and recovery rate * gender of candidate * temperature * amount of recovery time KEY VARIABLE: - The variable that I will be using is the duration of exercise, this is because it is easy to measure against any candidate and get a correct accurate reading from it. If I chose the type of exercise I will get readings that might not be correct because some types of exercises are
This study had many trials, but each trial consisted of six participants. Participants were told they were taking part in an experiment about visual judgment. Participants one through five had been told what to say while participant six had to use their own judgment to answer the questions. The participants are seated in order one through six; number one will give their answer first and then it will proceed
...r they complete the short survey, the experimenter will write on the top of the paper; which day the survey was distributed and whether or not they will receive a prize. For day one, we will be conducting the study in business attire, Level 1 of the Independent Variable 2, and half of our participants will be told of a prize at the end of the survey, Independent Variable 1. We will be measuring the ratings of the survey, Dependent Variable, and see if our attire has anything to do with their answers. Day two will be the same thing; the only differences will be that we, the experimenters, will be in workout clothing rather than business attire and that we will be distributing our surveys in a different area. We will again be measuring the effect of our workout attire, Level 2 of the Independent Variable 2; on the ratings of the survey our participants will receive.
The resulting participants were 100 adults aged 18 through 81. Fifty-three Caucasians, 17 Hispanics, 15 African Americans, 9 Pacific Islanders, 5 Asian, and 1 American Indian made up our participants. Fifty adults were randomly chosen to be in the control group and the other fifty adults were in the experimental group. The mean age of the control group was 50 years old and the mean age of the experimental group was 49 years old. 50% of the participants were female and 50% were male in each group.
All over the world, it is believed that physical exercises help people achieve wellness. Physical exercise not only encourages physical wellness but also have a significant impact on mental stability and health. Although such positive believes stand, many benefits of physical activity has lost value overtime, as people nowadays have the tendency to rely on modern technologies and machineries, which are believe to make life easier. This often leads to shortage of physical activity and over sometime both physical and mental health will deteriorate. This argumentative essay, will explain how engaging in physical exercises improve one’s mental health.
An experimental group is a group in the experiment that is getting tested on. Control groups, on the other hand, do not get the experiment tested on them. In most cases when dealing with a control group, a larger group, for example, will get divided into two smaller groups. One of them gets “tested” while the other group will step out just like what happened in class when the health and happiness experiment. When talking about the journaling experiment, though, because of our results I feel like a little bit of both happened. Since we know that some of the students did not participate in the journaling they act like the control group effect. But originally no, both of these shouldn't have happened only one should've and I feel like it would have most likely been an experimental group. If I could change one thing it would be to make this happiness experiment into the style of a control group. By doing so we would know if journaling what we are thankful for actually has an effect on our overall happiness. What would happen is the teacher would randomly choose half of the class to journal what they are thankful for every day and have the other half just continue doing what they do in their everyday lives. Keep the survey before and after the experiment to get an idea of the changes that take
The first step in conducting the study would be to randomly assign participants to two groups. One group would be the control group and would not be provided with vitamins, while the test group would be provided with vitamins.
...r daily activities, including their effort and ability contributing in their classroom performance.as a result of exercise, student’s energy balance also related to encouraging fitness outside the classroom because of the behavioural changes of their energy expenditure. Student’s risk of obesity is decreased by physical activity modifying their body composition. Beneficial changes to student’s immune systems comes from their interaction with structured and social exercise. This lowers students’ risk of becoming sick which can also relate to their classroom performance as they will not be missing vital learning time.
