You want to test the effect of sucralose on the growth of a plant. Design a study using the steps of the scientific method. What
Julli [10]

Answer:

  • The independent variable is the concentration of sucralose present in the plant.
  • The dependent variable is the growth rate of the plant.

Explanation:

The study designed through the steps of the scientific method would be done as follows:

Observation: Sucrose is a very important molecule for the development and growth of plants, based on which sucralose, which is formed from sucrose, can be important for the same factors.

Question: Can sucralose influence plant growth as well as sucrose?

Hypothesis: Sucralose may establish some influence on plant growth.

Experimentation: Select a number of seeds inoculated with sucralose molecules and select the same number of seeds that were not inoculated with anything. Provide the same type of soil and environmental factors so that seeds can grow in the same way. Weekly evaluate the growth of the plants generated by each seed for a certain period of time. After this period of time, measure the weight of the plants and their roots. Place the plant and root to dry in an oven and measure the weight of the plant and root once again.

Analysis of results: compare the average weekly growth of plants generated by inoculated seeds, with plants generated from uninoculated seeds. Compare the average weight of plants generated by seed inoculated before and after kiln-dried. Compare the weight average between plant roots generated by inoculated seeds before and after kiln-dried. Assess whether there was a significant difference between the means.

Conclusion: Using the data presented in the evaluation of the experiment, state whether the hypothesis developed provides true or false information.

<u><em>Note: it is important that the seeds are from the same species of plant.</em></u>
