HYPOTHESIS

OPINION

Understand that scientific findings should be reviewed by other scientists before they are published and that sharing these findings help to advance science

36. Who reviews articles for peer-reviewed journals?a. friends of the scientists who wrote the articlesb. anonymous and independent expertsc. the scientists who did the experimentsd. people who paid for the experiments

Understand that scientific findings should be reviewed by other scientists before they are published and that sharing these findings help to advance science

37. How does sharing ideas through peer-reviewed articles help advance science?a. Peer-reviewed articles are published only when the ideas they contain have been accepted by most scientists.b. Experiments in peer-reviewed articles do not need to be repeated.c. Scientists reading the articles may come up with new questions to study.d. Ideas in the articles always support and strengthen dominant theories.

Understand that scientific findings should be reviewed by other scientists before they are published and that sharing these findings help to advance science

38. A scientist discovers an important breakthrough in cancer treatment. The scientist thinks the information could save thousands of lives and immediately announces the results on national television, skipping peer review. How might other scientists react to this news?a. They will be skeptical because the report was not peer-reviewed.b. They will quickly start to use the new treatment on their patients.c. They will congratulate the scientist for the discovery.d. They will denounce the work and call the scientist a fraud.

NO

YES

NO

42. Recognize when an experiment is unethical AND explain whyA strange nerve disease attacked the people on an island. Symptoms of the disease included weakness and loss of appetite; victims often died of heart failure. Scientists thought the disease might be caused by bacteria. They injected healthy island inhabitants with bacteria from the blood of the sick patients. The injected people also became sick.
