The document defines science as the systematic study of the natural world through observation and experimentation. The main goal of science is to acquire knowledge about the world and apply it for humanity's benefit. The scientific method involves making observations, formulating hypotheses, conducting experiments, analyzing data, and drawing conclusions. Key steps include developing testable predictions from hypotheses and using deductive reasoning. While inductive reasoning allows generalizing from specific cases, the scientific method relies more on deductive reasoning to draw conclusions and minimize errors from exceptions.
