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.

The correct answer of the scientific experiments performed by the Brian in accordance with a scientific method are as follows:

1.  Question: A scientific question is a question which can have the real answers and can be tested therefore, Does the position of the pot determine the growth of the stem? is the correct option.

2. Hypothesis: A hypothesis is a well substantiated idea or opinion based on the observation thus, the plant’s stem grows perpendicular to the soil is correct.

3. Experiments: Experiments are performed in the to test the hypothesis which is shown by the statement Brian placed the pot horizontally. He checked the plant after two weeks.

4. Result: The data and observations based on the experiments is shown by the statement Brian found that the plant grew parallel to the soil.

5. Inconsistency with hypothesis : results not support the hypothesis.

5. Explanation: communicated the results to his science class.

6. Revision of hypothesis:

7. Retest.
