One of the statements below is not a goal of science. Using derived explanations to make predictions Using data to support a certain point of view Investigating and understanding the natural world Explaining events in the natural world

Scientists begin their work By forming and testing a hypothesis Designing an experiment Making conclusions Making careful observations about the world around them

A scientific theory is Another word for hypothesis A well-tested explanation that unifies a broad range of observations The same as the conclusion of an experiment The first step in a controlled experiment
