The Nature of Science The goal of science is to understand the world around us. Scientists attempt to solve mysteries of nature. Facts are truths about nature. When possible they perform experiments. They develop a scientific theory. A theory is the most logical explanation based on the facts. They don’t just guess. Theories may or may not be correct. These theories must be tested over and over again. If the theory passes each test, it may be accepted by the scientific community and become a law. Laws, like theories, may change as new information is provided and new experiments are performed. Science Process Skills Skills you need to be a “good” scientist!!
