A scientific hypothesis must be testable, meaning that it can be supported or refuted through experimentation or observation. This is what distinguishes a scientific hypothesis from a mere guess; it requires a structured approach where researchers can design experiments to collect data that either validates or invalidates their prediction. Additionally, a well-formulated hypothesis often follows an "if/then" structure, which clearly states the expected outcome based on an independent variable. For example, "If I water the plants more, then they will grow taller." This clarity helps guide scientific investigation and makes the hypothesis more robust for empirical testing.
