• Collection of data

• Evaluation and meaning of collected data

• Communication of collected data

• Keeping results hidden from others

It is important to not argue with scientific data that other scientists have already created

• True

• False

Answer explanation

Challenging other scientists' data and conclusions is an important part of the scientific process. Science is always changing, and many conclusions can seem correct until new data is produced at a later date.

Science is:

• Always in motion

• Static (does not change much)

No scientific knowledge provides the whole "truth". Instead, knowledge is:

• Replaced without regard to what has been learned in the past

• All scientific knowledge is reset every 25 years and we start over fresh to prevent incorrect knowledge from staying

• Knowledge is tested and added to what scientists have already learned

• Science is fake

What is repetition in reference to the scientific process?

• Someone else does the same experiment

• The same scientist does the same experiment again

• Someone else does a different experiment

• The same scientist does a different experiment

What is replication in reference to the scientific process?

• Someone else does the same experiment

• Someone else does a different experiment

• The same scientist does the same experiment

• The same scientist does a different experiment

Scientists use controlled experiments to test ideas. A controlled experiment seeks to keep all factors the same except the specific factor being tested. Which variables are NOT being tested and must remain the same?

• Open variable

• Independent variable

• Constant variable

• Knowledge variable

Scientists use controlled experiments to test ideas. A controlled experiment seeks to keep all factors the same except the specific factor being tested. Which variables IS being tested?

• Constant variable

• Open-ended variable

• Alpha variable

• Independent variable

Which variable is measured by the scientist to prove or disprove the scientific question?

• independent variable

• The dependent variable/outcome variable

• Constant variable

• Beta variable

Answer explanation

The constant variables stay the same to maintain the integrity of the experiment.

The independent variable is changes, and is the CAUSE of the dependent variable/experimental outcome

The dependent variable or outcome variable is the entire purpose of the experiment. It is what the scientist is trying to measure or observe.
