The goal of science is to investigate and understand the natural world, to explain events in the natural world, and to use those explanations to make useful predictions. 12. An observation is a process of gathering information, while an inference is a logical interpretation based on prior knowledge or experience. During an observation, you just see and gather. But during an inference, you use your mind to make an interpretation. 13. A hypothesis helps scientists explain what they observe in the natural world. 14. A hypotheses may arise from prior knowledge, a creative imagination, or a logical inference. 15. When a scientist tests only one variable, it gives him more control of the experiment. The scientist can easily figure out the results of the experiment, because there would only be one change. 16. A variable is a factor in an experiment that changes, and the controls in the experiment are the factors in the experiment that stay the same. If there were no controls, then the conclusion would not be accurate.
