Science is a body of knowledge about the world developed through the scientific method. Observations about the world lead to hypotheses or educated guesses about why things are the way they are. The hypotheses are then tested and based on the results of the test the hypotheses is proved wrong or not. Here are some different courses in science that you might consider taking now or in the future.
Physics is the study of matter and energy and their interaction. It is the study of why things move the way they do, or why stay where they are. A basic understanding of physics is very important in every engineering field.
Chemistry is the study of the composition, structure, and physical properties of substances and the reactions that produce or convert them into other substances. Like physics, a basic understanding of chemistry is important in every engineering field.
Biology is the study of living organisms. There are several specialized sciences that are part of biology including botany, zoology, microbiology, and genetics. An understanding of living systems is important to all engineers, but especially those working on environmental, agricultural, and medical problems.
Sometimes taught as environmental science, ecology is the study of how living organisms and the physical environment interact. A basic understanding of how things in nature are connected is important to all engineers, not just to those working on environmental projects.
There are several other sciences that you may consider learning about: Anatomy, the study the human body; Anthropology, the study of cultures; Astronomy, the study of stars and the cosmos; Economics, the study of markets and resource allocation; Psychology, the study of human senses; and Sociology, the study of societies or people in groups.
