Brian is interested in plants. He notices that most plants always grow in an upward direction, which is against gravity. He conducts an experiment to check whether his observation is correct. Arrange the steps of the experiment in order according to the scientific method.

He wondered, Does the position of the pot determine the growth of the stem?

To test his hypothesis, Brian placed the pot horizontally. He checked the plant after two weeks.

Brian observed that a plant's stem grows against gravity.

He hypothesized that the plant's stem grows perpendicular to the soil.

Brian communicated the results to his science class.

On analysis, Brian found that the plant grew parallel to the soil. He modified the hypothesis, and then retested the experiment.
