A scientist who performs an experiment has no idea what the outcome of the experiment is going to be true or false?

True. In an experiment, a scientist formulates a hypothesis, designs the experiment, collects data, and then analyzes the results to draw conclusions. The outcome of the experiment is not known beforehand, and it is the results of the experiment that will either support or refute the hypothesis.

manipulated variable


What is an artificial situation in which a scientist deliberately makes certain changes in the world about him so that he can observe the consequences?

An artificial situation created by a scientist to observe the consequences of specific changes is called an experiment. In an experiment, the scientist manipulates variables to test hypotheses and determine the impact of those changes under controlled conditions. This method allows for the identification of cause-and-effect relationships in the natural world.


What goal of a scientist is to design an experiment that will be able to distinguish the difference between what?

The scientist wants to design an experiment that will demonstrate the effect of the independent variable on the dependent variable. This idea is to show causality between the two.


Why should paleontologist be patient?

A scientist should be patient and wait calmly for the result of the investigation or experiment.So he can finished or accomplish his work and always read to try again especially when things don't work out. For example: A scientist is working on an experiment and the result of it is taking to long and he tends to live the experiment.Not knowing if he will be successful to his experiment. So a scientist should be patient and try again if he doesn't succeed.
