Science differs from other disciplines, such as history and the arts, because science relies on

• facts.

• observations

• theories.

• testing explanations.

Measurements made while observing a plant grow 3 cm over a two-week period are called

• hypotheses

• inferences

• data

• variables

Based on your observations, you suggest that the presence of water could accelerate the

• an experiment.

• a hypothesis

• an analysis

• a conclusion

Suppose that a scientist proposes a hypothesis about how a newly discovered virus affects humans. Other virus researcher

• design new experiments to test the proposed hypothesis

• change the hypothesis to fit their own findings.

• reject the hypothesis right away

• assume that the hypothesis is true for all viruses

Why is creativity considered a scientific attitude?

• Creativity helps scientists come up with different experiments

• Creative scientists imagine the results of experiments without doing them

• Scientists who are creative are better at handling and training animals

• Scientists need creativity to make good posters to explain their ideas

Who reviews articles for peer-reviewed journals?

• the scientists who did the experiments

• friends of the scientists who wrote the articles

• anonymous and independent experts

• people who paid for the experiments

How does sharing ideas through peer-reviewed articles help advance science?

• Experiments in peer-reviewed articles do not need to be repeated.

• Scientists reading the articles may come up with new questions to study.

• Ideas in the articles always support and strengthen dominant theories

• Peer-reviewed articles are published only when the ideas they contain have

Suppose that a scientific idea is well-tested and can be used to make predictions in numerous new situations, but cannot

• theory that should be discarded

• hypothesis that is incorrect.

• hypothesis that must be retested

• theory that may need revision

How do scientific theories compare to hypotheses?

• Theories unify a broad range of observations and hypotheses

• Theories are the same as hypotheses

• Hypotheses are the dominant view among scientists

• Hypotheses combine the ideas of several theories to explain events

Which of the following is NOT a way that science influences society?

• Science provides answers to some of society’s practical problems

• Science gives society answers to difficult ethical issues
