False
Scientists get information from research, observations, experiments, and other scientists.
they use controlled experiments to help them find out if it works or not.
Experiments helps scientist test the ideas. Experiment is simply an act of performing a controlled test about an idea. Before an experiment is made, observations using senses must be deduced from the environment at first. Observations leads to the formulation of hypothesis.
it is called data
To ensure results are of optimal percent error, scientists must manipulate only one variable. Therefore, they use controlled experiments.
Scientists use controlled experiments because the results are consistent and can be replicated. The control of an experiment is the value that you are controlling the dependent variable to.
Form a question. Develop a hypothesis. Make observations. Conduct controlled experiments. Make predictions. Collect data. Analyze data. Develop a conclusion.

Scientist use models
theory
Through personal experience and previous observations and experiments.
