Stella wants to test the hypothesis “If carbon dioxide levels increase, the growth rate of sunflowers will increase.” She places five young sunflower plants into similar containers and sets up pumps that release different amounts of carbon dioxide into each container. She plans to measure the daily height of the plants for two weeks and graph the data. Which additional considerations would produce the most reliable experimental results?

Answer:

She should place one flower in a similar container, but not pump carbon dioxide into it. She should also give each plant the same amount of water.

An additional considerations that would produce the most reliable experimental results is that Stella should set up a control group in the experiment.

CONTROL GROUP:

  • A control group in an experiment is the group that does not receive the experimental treatment or independent variable.

  • According to this question, Stella wants to test if the level of carbon dioxide will affect the growth rate of sunflowers. This means that the carbon dioxide levels is the independent variable of the experiment.

  • However, she places five young sunflower plants into similar containers and sets up pumps that release different amounts of carbon dioxide into each container.

  • Stella did not set up a control group that will not receive the carbon dioxide in her experiment. This should be done to produce the most reliable experimental results.
