1.4-Work Like a Scientist

An organized way to collect and record scientific observations is with a(n)

• model.

• inference.

• data table.

• operational definition.

Which stage of the scientific process enables a scientist to check the work of other scientists?

• classifying

• concluding

• hypothesizing

• communicating

During an experiment, which factors must be controlled so that researchers can draw a logical conclusion from the experiment?

• variables

• operational definitions

• inquiries

• theories

Observations that deal with descriptions that cannot be expressed in numbers are called

• manipulated observations.

• quantitative observations.

• qualitative observations.

• operational observations.

Observations that deal with a number or amount are called

• manipulated observations.

• quantitative observations.

• qualitative observations.

• operational observations.

One useful tool that may help a scientist interpret data by revealing unexpected patterns is a

• variable.

• graph.

• theory.

• law.

A summary of what you have learned from a scientific experiment is called a(n)

• hypothesis.

• inquiry.

• conclusion.

• law.

• Claim
• Variable
• Scientific Inquiry
• Hypothesis

Factor that you keep the same in an experiment

• Independent Variable

• Dependent Variable

• Constant

• Operational

What variable in an experiment is the manipulated variable?
For example: keep bread at room temp, and keep another one in the refrigerator- here you are changing the temps on purpose to see what happens. 

• Operational Definition
• Control Variable
• Dependent Variable
• Independent Variable
