Which statement best describes observations?

Which statement best describes observations?

• A. Facts, measurements, information, data collected using the senses
• B. Opinions not based on data
• C. A theoretical model
• D. A prediction about outcomes

Answer: (A)

Observations are the factual, verifiable elements gathered from the natural world through senses and instruments. They include facts, measurements, information, and data collected directly—like noting the color of a mineral, its hardness, or a measured temperature. These observations provide the raw material scientists use to understand phenomena and to build explanations. Other options describe things that aren’t direct observations: opinions not based on data are subjective beliefs; a theoretical model is an organized framework for explaining observations; a prediction is a forecast about what will happen in the future. Since the question asks for what best describes what is observed, the first option is the accurate choice.
