Scientific Investigations

Information gathered from observing a plant grow 3 cm over a two-week period is called

• inferences

• variables.

• hypotheses.

• data.

Suppose that a scientist proposes a hypothesis about how a newly discovered virus affects humans. Other virus researchers would likely

• reject the hypothesis right away.

• change the hypothesis to fit their own findings.

• design new experiments to test the proposed hypothesis.

• assume that the hypothesis is true for all viruses.

The work of scientists usually begins with

• testing a hypothesis.

• careful observations.

• creating experiments.

• drawing conclusions.

The quality of research is judged by the

• Experiment

What is an example of Initial Observations and Asking Questions?

• Noticing grass is larger in some areas than others and asking "Why?"

• Supposing that it grows more in some areas because of nitrogen levels

• Choosing similar plots. Exposing one group of plots to nitrogen and not exposing the other group.

• Analyzing the results to see that grass in the experimental group grew more.
