The anatomy of a question: moving from observation to experiment
In short: Scientific discovery begins with the right kind of question. This lesson breaks down how to transition from simple observations into testable experimental questions that drive real-world investigation.
To conduct a rigorous experiment, scientists must distinguish between different types of inquiries. While an observation is a statement about what is noticed, an experimental question specifically guides a testable scientific experiment. This process relies on identifying variables: the independent variable (the cause being manipulated) and the dependent variable (the effect being measured).
Drawing from the NRC's 'A Framework for K-12 Science Education', this structure prompts learners to construct hypotheses using scientific concepts and evidence. It also advises that inquiries must be manageable given the specific tools found in museums or school settings.
