What is a hypothesis in a science experiment?

• A. A testable prediction.
• B. A final conclusion.
• C. A measurement.
• D. A theory.

Answer: (A)

In science, a hypothesis is a testable prediction about what will happen in an experiment. It states a relationship between variables that you can measure and check, and it must be something you can prove false with evidence. For example, saying that increasing sunlight will cause a bean plant to grow taller is a prediction you can test by controlling light and measuring growth over time. After you collect data, you see whether the results support the prediction or not. This differs from a final conclusion (what you decide after analyzing data), a measurement (the data you collect), or a theory (a well-supported explanation that covers many observations).
