What is Science?

Some people wonder whether science is a body of knowledge or a process. It is really both! Science is a way of learning about the natural world through observation and logical reasoning. Science also includes a body of information that can grow and change as new ideas are explored. Another term for the ongoing process of discovery in science is scientific inquiry. It refers to the various organized methods of investigating problems and answering questions. Science can be broken down into various general disciplines. They include the earth sciences - a study of the earth and its processes including space science, biological science - the study of life, and physical science - the study of matter, energy, and the changes that matter and energy undergo.

Although there is no one "scientific method", scientists of all disciplines utilize a variety of skills. Some of the skills used by scientists include posing questions, making observations and inferences, developing hypotheses, and conducting experiments.

Scientists use the five senses to make observations of the world around them. To enhance the ability of scientists to make observations technology has been developed over time that has allowed us to view our world in many different ways. Some tools that are used to help make measurements include the thermometer, a tool that allows the user to compare the temperature of a substance. The thermometer extends our sense of touch and places a value that we can record as data for later comparison. The microscope and telescope enhance our sense of sight by allowing us to see things that we are unable to see with the naked eye.
