What is a prediction in scientific terms?

• A. A statement about what will happen in the future based on observation.
• B. A guess without basis.
• C. A measurement of current value.
• D. An established law.

Answer: (A)

In science, a prediction is a statement about what will happen in the future based on observations, data, and patterns that have been observed. It’s a testable claim you can check by carrying out an experiment or further observations under the same conditions. This makes it different from a guess, because it relies on evidence and can be supported or refuted by results. It isn’t simply measuring the present value, and it isn’t an established law, which describes a general relationship that holds in many situations but doesn’t specify a single future outcome. For example, if data show that increasing temperature speeds up a reaction, you would predict the reaction will proceed faster at a higher temperature under the same conditions.
