What is the difference between an observation and a conclusion in science?

Correct answer: Observation is direct information and conclusion explains its meaning

The direct answer is option A: an observation is direct information, while a conclusion explains its meaning. An observation is something recorded through the senses or instruments, such as “the liquid temperature is 60°C” or “the plant grew 3 cm.” A conclusion is the reasoned statement drawn from such observations, such as “greater light may have supported growth.” The reasoning is: first collect or record what was seen or measured; then examine the evidence and explain what it suggests. Option A is correct because it separates evidence from interpretation. Option B is wrong because an observation and a conclusion have different jobs. Option C is wrong because observations normally come before conclusions; one should not decide the result first. Option D is wrong because observations should be based on evidence, including careful seeing or measurement. Memory cue: observation is “what happened”; conclusion is “what it means.”
