What is the correct way to make a scientific observation objective?

Answer and explanation

Correct answer: Record only what is observed or measured

The direct answer is B: record only what is observed or measured. An objective observation is based on facts available to the senses or instruments, not on expectations, guesses, or opinions. Step by step, watch carefully, measure when possible, write the actual value and unit, and avoid changing the record to fit a prediction. B is correct because it separates evidence from interpretation. A is wrong because recording only expected events hides unexpected evidence. C is wrong because a friend's opinion is not the observation itself. D is wrong because guessing a result is a prediction, not an observation. For example, “the liquid is 25 °C” is an observation, while “the liquid is good” is an opinion. Memory cue: write what happened, not what you hoped would happen.
