1. Why is the Scientific Method a powerful tool?
The scientific method is a powerful tool because it allows one to generate accurate and repeatable predictions if each step is taken correctly.
2. What are the two classes of investigation? Be able to name and describe each using examples.
The first class of investigation is the descriptive investigation, which is an inductive method that investigates associations between facts and infers general information from a pool of observations or facts. An investigation that is descriptive would be one in which students were observed to determine which lunch selections were the most preferred. The second class of investigation is the experimental investigation, which is a deductive method that seeks to explain cause-and-effect relationships by utilizing a control variable and altering an independent variable to see its effects. An investigation that is experimental would be one in which multiple of the same plant were grown in

Is it better for a hypothesis to be general or specific?
Generally, it is better for a hypothesis to be specific, as it allows for one to come to an answer of “yes” or “no” or comparably easy conclusions as to whether the hypothesis was correct. However, hypotheses can be general or specific, and this depends on what idea one is examining.
8. Does science prove things?
Science cannot always prove things due to our own limitations on what questions we know to ask, how to ask them, how to test them, and in our abilities to observe and understand the world and its phenomena wholly. Instead, science more often disproves things; we disprove null hypotheses to prove research hypotheses and disprove outdated ideas and theories with the results of novel and replicated experiments.
9. Being able to reject the null hypothesis accomplishes what?
Being able to reject the null hypothesis allows us to accept the research hypothesis.
10. What role does probability play in accepting the validity of
Make an observation of a problem or question to answer. 2.Background research. Looking into background research into
M1, Introduction There is always a question which can’t be answered by scientist all of which relate to the perceptions of science as there is difference in how science is currently addressed. Also, people have different believes, opinions and interpretation of science in general. Questions science is currently addressing- cure for cancer?
I have seen both of these terms mentioned in numerous research articles but I never understood why researchers applied the technique to their study. Part II We will review your postings and answer your questions and clarify/correct anything that needs correcting. Part III Create one multiple choice test question, either from your own topic or one of your classmate 's topics.
investigating the difference in results of using two different types of plant food Ans: identification of Relationship because trying to identify difference between two types of food. h. calculating the mean score on a final exam for a class of 100 students Ans: data reduction because trying to reduce everything and shows meaningful part. i. studying whether exposure to a certain type of chemical results in more frequent cancer diagnoses Ans: Inference because it tries to conclude how certain types of chemical results in more frequent cancer diagnoses. 3. Tell which type of sampling is used (random, cluster, systematic, convenience, and stratified and give clear reasons to support your answer.
In conclusion, the characteristics of the scientific method are far from few. Most distinctly, science deals with the uncertainty of the unknown, attempting to make it known. Though complicated, Barry explains his beliefs on the scientific method with strong diction to show the formality of science, rhetorical questions to show the uncertainty, and logos to show the intellect of science. His rhetorical strategies help the audience understand the plethora of characteristics in the realm of
Science is something people have confidence in because they know that when science is involved in a study, that they study is
Topic: Latino youth in the foster care system Research question: How do the relationships that primarily lead low-income Latino youth into foster care systems initiate. • I used the word relationships because I’m not talking about a relationship between a father and a son or a father daughter relationship. I’m addressing the relationships between the families as a whole. • I used the word primarily because I will be looking into the top three reasons why youth get sent into foster care systems.
c. What is the research question or hypothesis? a. My hypothesis is that children who are exposed or given the opportunity to use these devices or are exposed to these devices at a young age will have or obtain more knowledge than a child who are not. d. What sort of research design are you proposing? (e.g. correlational, descriptive observational, experimental, etc.)
8) Explain how each experiment type (question 7) differs from the
The scientific method is paramount to scientists and their studies. Barry affirms, “Ultimately a scientist
A way to encourage scientific enquiry in the classroom is through the use of practical investigations. In the context of thinking and working scientifically, investigations are activities where children can use their conceptual understanding and knowledge of science to find solutions to problems and questions (Skamp, 2012). Supported by Ward et al. (2006) who say that the term investigation is used for activities requiring children to make choices about what to change and measure. Instances where science lessons are practical and focus on the development skills linked with scientific enquiry and where emphasis was placed on the children carrying out investigations independently, were the most beneficial (Ofsted 2010).
Science says that in order for something to be a fact it needs to have many accounts of observable and repeating evidence that supports
A number of basic standards for determining a body of knowledge, methodology, or practice are widely agreed upon by scientists. One of the basic notion is that all experimental results should be reproducible, and able to be verified by other individuals.[13] This standard aim to ensure experiments can be measurably reproduced under the same conditions, allowing further investigation to characterize whether a hypothesis or theory related to given phenomena is valid and reliable. Philosopher Karl Popper (?) in one of his project attempted to draw the line between science and pseudo-science.
Science provides a wealth of knowledge that can be tapped to enhance the provision of healthcare in the world. Science and healthcare are closely interconnected and there is need to come up with measures that enhance the positive use of science in the healthcare setting. Healthcare personnel are trained using scientific methods, and day to day operations at healthcare facilities are based on science. Treatment plans such as different medicines, surgery and laboratory procedures are all based on scientific methods. However, if not used properly, science can also create problems to healthcare provision.
