Why is careful note-taking useful in science?

Correct answer: To keep an accurate record of observations and results

The direct answer is A: careful notes keep an accurate record of observations and results. Science depends on evidence that can be checked later. During an experiment, write the date, materials, conditions, readings, units, unusual events, and final result in the order they occur. Do not rely on memory. A is correct because clear notes preserve what was actually seen and measured. B is wrong because handwriting improvement may be useful, but it is not the scientific purpose. C is wrong because notes must represent the evidence, not a desired answer. D is wrong because recording observations supports the experiment and does not stop it. A good record allows another person to understand or repeat the work. Memory cue: observe, measure, record, and review.
