Please help me with the following:
A science class tested ways to clean water after an oil spill. Each group of students was given 100 mL of vegetable oil, 100 mL of engine oil, and 800 mL of water in a rectangular plastic container. Each container also held five floating wooden cubes (5 cubic centimeters each) representing animals in the water. Each group was tasked with removing as much oil as possible in a 20 minute period, leaving “clean water” in the container, using whatever tools they brought to class. The results of the “clean-up” are presented in the table below.
Group_Vegetable oil removed (mL)__Engine oil removed(mL)
__1____________10_______________________20
__2____________110______________________130
__3____________60_______________________40
__4____________80_______________________70
A. Group 1
B. Group 2
C. Group 3
D. Group 4
I think the answer is B. Is B correct?
The scientific evidence that scientists use in supporting or critiquing the conclusions of experiments usually consists of
A. raw data.
B. outlier data.
C. precise data.
D. summarized data.
I think the answer is D. Is D correct?
Which statement describes a problem with the peer review process in scientific research?
A. It can sometimes reject important new ideas or novel techniques.
B. It forces new scientists to meet the same standards that established scientists meet.
C. It always requires scientists to have to reanalyze their data.
D. It often makes it more difficult to justify a conclusion.
I think the answer is A. Is A correct?
Please help me by checking my answers. Any help will be greatly appreciated!!! :)
P.S. There may be more to be checked.
I agree on all.
Thank you Bobpursley!!!! :)
You helped me get 100%!
Which statement best describes a valid scientific claim?
The results of the experiment can be replicated by using any method of experimentation.
The results that support the claim are replicable by other scientists who follow the same procedures.
The claim is jointly issued from both a major university and an established government agency.
The claim is supported by at least ten scientists in addition to the original researcher
Let's go through each question and check your answers:
Question 1: The question asks which group removed the most vegetable and engine oil. Looking at the data in the table, we can see that Group 1 removed 10 mL of vegetable oil and 20 mL of engine oil, Group 2 removed 110 mL of vegetable oil and 130 mL of engine oil, Group 3 removed 60 mL of vegetable oil and 40 mL of engine oil, and Group 4 removed 80 mL of vegetable oil and 70 mL of engine oil.
Based on the data, Group 2 removed the most oil overall, so your answer of B. Group 2 is correct.
Question 2: The question asks which type of data scientists use to support or critique the conclusions of experiments. The options given are raw data, outlier data, precise data, and summarized data. Raw data refers to the original unprocessed data collected in an experiment, outlier data refers to data points that are significantly different from the rest of the data, precise data refers to data with a high level of accuracy and precision, and summarized data refers to data that has been analyzed and presented in a condensed form.
Based on the question, scientists use summarized data to support or critique the conclusions of experiments. So your answer of D. summarized data is correct.
Question 3: The question asks which statement describes a problem with the peer review process in scientific research. The options given highlight different aspects of the peer review process. Option A states that peer review can sometimes reject important new ideas or novel techniques, Option B states that it forces new scientists to meet the same standards as established scientists, Option C states that it always requires scientists to reanalyze their data, and Option D states that it often makes it more difficult to justify a conclusion.
Among these options, Option A mentions a potential problem with peer review rejecting important new ideas or novel techniques, which can be seen as a valid concern. So your answer of A. It can sometimes reject important new ideas or novel techniques is correct.
Based on the checking, your answers are correct for all the questions. Well done! If you have any more questions, feel free to ask.
