Scientific describes anything related to science or done using the careful, systematic methods that scientists use. When you conduct a scientific experiment, you're following specific steps: forming a hypothesis, testing it carefully, measuring your results, and drawing conclusions based on evidence rather than guesses or wishes.

The word captures a particular way of thinking. A scientific approach means being precise, objective, and willing to change your mind when the evidence shows you're wrong. If you're trying to figure out which paper airplane design flies farthest, you'd use scientific methods: testing each design multiple times, measuring the distances carefully, and keeping track of your results in an organized way.

Scientists work in many fields, from astronomy to zoology, but they all share this scientific mindset. They ask questions, gather evidence, test their ideas, and accept what the data reveals, even when it surprises them. When someone makes a scientific discovery, they've learned something new about how the world works through systematic investigation rather than speculation.

The opposite of scientific is often described as unscientific: making claims without evidence, ignoring data that contradicts your beliefs, or refusing to test your ideas properly. Someone might have a “gut feeling” about something, but a scientific thinker asks: can we test that? What does the evidence actually show?
