What are observations?

Explanation:
Observations are the facts and measurements you collect about the world by using your senses or scientific instruments. They are the actual evidence you can describe or quantify—things like color, texture, temperature, or the length of a sample. Observations can be qualitative or quantitative and they form the data base scientists use to understand phenomena. They’re different from opinions (beliefs not based on data), hypotheses (testable explanations proposed after considering observations), and predictions (forecasts about what will happen under certain conditions). So, observations are the data you record from the natural world, not interpretations or future expectations.
