- The presence of the supernatural, for instance, is neither testable nor falsifiable. To test a hypothesis, a researcher will conduct one or more experiments designed to eliminate one or more of the hypotheses. Each experiment will have one or more variables and one or more controls. A variable is any part of the experiment that can vary or change during the experiment. The control group contains every feature of the experimental group except it is not given the manipulation that is hypothesized. For example, a control group could be a group of varied teenagers that did not drink milk and they could be compared to the experimental group, a group of varied teenagers that did drink milk. Thus, if the results of the experimental group differ from the control group, the difference must be due to the hypothesized manipulation rather than some outside factor. To test the first hypothesis, the student would find out if drinking milk affects height.Link: https://arxiv.org/abs/2006.05121
- If drinking milk has no affect on height, then there must be another reason for the height of the friend. To test the second hypothesis, the student could check whether or not his friend has tall parents. Each hypothesis should be tested by carrying out appropriate experiments. Be aware that rejecting one hypothesis does not determine whether or not the other hypotheses can be accepted. It simply eliminates one hypothesis that is not valid. Using the scientific method, the hypotheses that are inconsistent with experimental data are rejected. For instance, a student might attend class on Monday and realize she had difficulty concentrating on the lecture. The scientific method may seem too rigid and structured. It is important to keep in mind that although scientists often follow this sequence, there is flexibility.Link: https://nvidia.com/en-us/data-center/dgxperts/
- Many times, science does not operate in a linear fashion. Instead, scientists continually draw inferences and make generalizations, finding patterns as their research proceeds. Scientific reasoning is more complex than the scientific method alone suggests.

- In an experiment, the factor that we measure is called the A dependent variable C independent variable D controlled variable 6. A scientist conducted an experiment to determine how the amount of salt in a body of water affects the number of plants that can live in the water. In this experiment the dependent variable is A the amount of salt in the water B the number of plants in the water C the water D the temperature of the water 7. All the things in an experiment that must be the same to make it fair are called A dependent variables B controlled variables or constants C independent variables 8. If you do not understand a direction or part of a lab procedure you should A ask your teacher B try several methods until one works C skip it and go to the next part D figure it out as you go If you break glassware, like a beaker you should A sweep the glass off the table and put in the trash.Link: https://examples.yourdictionary.com/examples-of-adjectives.html
- B immediately notify the teacher and those around you to the hazard, and never clean up yourself. C crush the remaining glass down for easier disposal. D conceal the accident so your group does not get in trouble. If you have been injured in the laboratory cut, burn,etc. B see a doctor after school. C apply first aid yourself. D tell the teacher immediately Whose responsibility is it to care for lab equipment and to report damage A every person participating in a lab has the responsibility.Link: https://ccna-200-301.online/ccna1-v7-itn-practice-final-exam-answers/
- B only the person assigned to that task. C the principal mainly. D only the teacher has the responsibility Horseplay, practical jokes, and pranks in the science lab are A not dangerous. C okay if you are working alone. D always against the rules. What is the main classroom rule for this class? A stay in my seat B respect myself and others C there are no rules D be quite at all times Approved eye protection devices, like goggles, are worn in the lab A to avoid eye strain.Link: https://e-eduanswers.com/mathematics/question19461466
- The scientific method is defined as a method of research in which a problem is identified, relevant data is gathered, a hypothesis is formulated from this data, and the hypothesis is empirically tested. What in the world does that mean?!? In simple terms, the scientific method is a way for scientists to study and learn things. It doesn't matter what the scientist is trying to learn, using the scientific method can help them come up with an answer. The first thing to do with the scientific method is to come up with a question. You can't find the answer until you know the question after all!Link: https://hscj.ufl.edu/obgyn/docs/colposcopy-course.pdf
- Next you need to observe and gather information in order to come up with a guess called a hypothesis or a number of guesses to the answer. Next, you run experiments to see if your guess is right. A key to good experiments is to only change one thing, or variable, at a time. This way you can check your results and know what you changed that changed the answer. Carefully controlling your experiments is an important part of the scientific method. Finally, after running all the tests you can think of, you analyze your data. If you find that the results do not fit with your original hypothesis, you can now change your hypothesis and run more tests, if necessary. By going through this process, scientists have a way to verify their guesses and to double check each other.Link: http://aab.virgiliogroup.it/vignette-certification-exam-answers.html
- Another scientist can take a look at your tests and add some more tests and continue to refine your answer to the question. Scientific Method Steps As described above, there are specific steps that should be taken when using the scientific method. Here is an example of the steps: Ask a question Gather information and observe research Make a hypothesis guess the answer Experiment and test your hypothesis Analyze your test results Modify your hypothesis, if necessary Present a conclusion Retest often done by other scientists History of the Scientific Method The scientific method wasn't invented by one person, but was developed by different scientists and philosophers over the years.Link: https://chegg.com/homework-help/questions-and-answers/find-expected-error-following-test-inputs-10u-t-10tu-t-10t2u-t--q49194770
- For something that sounds so simple and basic, there are still long scientific papers written about the method and scientists who disagree on exactly the best way to implement it. Francis Bacon, Rene Descartes, and Isaac Newton all helped contribute to the development of the scientific method as a good way to learn about nature and science.Link: https://paktechpoint.com/mechanical-qc-inspector-question-answers-cbt-aramco/
- They wrote papers and discussed how using experiments and changing variables can help to determine if a guess or hypothesis is correct. Why is the Scientific Method Important? The scientific method is the cornerstone to modern science. Without a formal method of determining questions and their answers, we wouldn't have science or the knowledge we have today.Link: https://uk.answers.yahoo.com/question/index?qid=20100614093359AAx4gjm
- What is one controlled variable in this experiment? A controlled variable is one which the researcher holds constant during an experiment. It is not part of an experiment, but it is important because it can have an effect on the results. Any given experiment has numerous control variables. There is a title that clearly tells us what the graph shows The units used for any measurements must be clearly indicated on one of the axes Points we have drawn for a line graph must be connected by RULED lines If a pie graph shows percentages, they What best describes the importance of using a control group?Link: http://ignou.ac.in/ignou/aboutignou/icc/ncide/OIA
- A control group is a standard or a scale in an experimental study on which the other subject is being measured. A control group allows you to compare those receiving the variable and those that are not. A scientific control group is an integral part Is it true that an independent variable is a factor that changes because of procedures conducted on the dependent variable? The answer to this is false. What is an independent variable? This is a variable that has a variation that will not depend on another variable. This means that if in case there are some changes that are made with the whole experiment, the independen.Link: https://sciencedirect.com/topics/engineering/body-in-white

- Psychologists may induce stress, anxiety, or negative moods in their participants, expose them to weak electrical shocks, or convince them to behave in ways that violate their moral standards. And researchers may sometimes use animals in their research, potentially harming them in the process. Decisions about whether research is ethical are made using established ethical codes developed by scientific organizations, such as the Canadian Psychological Association, and federal governments.Link: http://barnardlevit.co.uk/assets/Lectures/Vitreous-and-Peripheral-Retinal-Conditions.pptx.pdf
- Characteristics of an Ethical Research Project Using Human Participants Trust and positive rapport are created between the researcher and the participant. The rights of both the experimenter and participant are considered, and the relationship between them is mutually beneficial. The experimenter treats the participant with concern and respect and attempts to make the research experience a pleasant and informative one. Before the research begins, the participant is given all information relevant to his or her decision to participate, including any possibilities of physical danger or psychological stress. The participant is given a chance to have questions about the procedure answered, thus guaranteeing his or her free choice about participating. After the experiment is over, any deception that has been used is made public, and the necessity for it is explained. The experimenter carefully debriefs the participant, explaining the underlying research hypothesis and the purpose of the experimental procedure in detail and answering any questions.Link: https://uk.answers.yahoo.com/question/index?qid=20200330082500AAQ1DGg
- The experimenter provides information about how he or she can be contacted and offers to provide information about the results of the research if the participant is interested in receiving it. Stangor, This list presents some of the most important factors that psychologists take into consideration when designing their research.Link: https://amazon.com/Sony-Z8H-75-Inch-Compatibility/dp/B084KYMQ2R
- The most direct ethical concern of the scientist is to prevent harm to the research participants. One example is the well-known research of Stanley Milgram investigating obedience to authority. In these studies, participants were induced by an experimenter to administer electric shocks to another person so that Milgram could study the extent to which they would obey the demands of an authority figure. Most participants evidenced high levels of stress resulting from the psychological conflict they experienced between engaging in aggressive and dangerous behaviour and following the instructions of the experimenter.Link: https://austin360.com/story/entertainment/2021/01/19/austin-trivia-quiz-texas-test-experts/4157989001/
