The word “science” comes from the Latin word “scientia”, which means knowledge. Science covers the broad field of knowledge that deals with facts and the relationship among these facts.
Scientists study a wide variety of subjects. Some scientists search for clues to the origin of the universe and examine the structure of the cells of living plants and animals. Other researchers investigate why we act the way we do, or try to solve complicated mathematical problems.
Scientists use systematic methods of study to make observations and collect data. They develop theories that help them order and unify facts. Scientific theories consist of general principles or laws that attempt to explain how and why something happens or has happened.
