All experiments start with a question. In order to formulate a hypothesis, or make a prediction about the outcome of an experiment, the question must be testable. Testable questions are those questions that can be answered through experiments and observations. They involve measurable variables and lead to observable outcomes that can be recorded and analyzed. On the other hand, non-testable questions usually involve opinions, personal beliefs, or other concepts that cannot be objectively quantified or measured.
