Scientific Method

What do we call a process of collecting information?

• Analyzing results

• Making observations

• Formulating a question

• Making a conclusion

Process of making an observation includes

• Viewing only

• Taking measurements only

• Recording only measurements

• Viewing, taking measurements, and recording everything

What do we call a possible explanation to a problem that has not yet been tested.

• data

• theory

• hypothesis

• fact

The summary at the end of an experiment that explains the results is called...

• conclusion

• procedures

• materials

• responding variable

What do we call a series of steps used by scientists to solve a problem or answer a question.

• scientific method

• recipe

• data collection

• A hunch

Should experiments be repeated over and over to see if the results are the same each time?

• yes
• no

To test a hypothesis we must

• find an answer

• design an experiment

• solve a problem

In order to be accepted, a scientific theory must be

•  widely tested and supported by extensive data
•  based on the results of a single experiment
•  controversial and cause debate
•  in line with all previous historical ideas

In an appropriately designed experiment, a scientist is able to test the effect of

• a single variable

• multiple variables

• the hypothesis

Which statement best expresses a basic scientific assumption?

• Interpretation of experimental results has provided explanations for all natural phenomena.
• If a conclusion is valid, similar investigations by other scientists should result in the same conclusion.
• For any conclusion to be valid, the design of the experiment requires that only two groups be compared.
• After a scientist formulates a conclusion based on an experiment, no further investigation is necessary.
