Scientists perform experiments to collect data.
To answer specific questions
research or background information
perform several independent experiments on the same topic
Scientists investigate the natural world by observing it very closely, and they perform experiments and studies.
They make sure the result is right
without it scientists wouldn't be able to perform experiments and thus, wouldn't learn anything.
since the beginning of time
They set out to test a hypothesis by using experiments and controls. They then adjust the experiments and run the tests again until they either prove or disprove it.
why do scientist perform experiments?
Chemists perform experiments to find out different kinds of matter can change.
