Please solve this lab reportJohn had a science fair project that he needed to do. He wanted to test the effects that organic and chemical fertilizers had on plant growth. John predicted that the organic fertilizer would make the plants grow taller. He used three pots, three of the same type of seed, soil, organic fertilizer, chemical fertilizer, water, and a ruler. John put soil in the pots. He added chemical fertilizer to the first pot, organic fertilizer in the second pot, and no fertilizer in the third pot. He then planted one seed in each pot. John had to water the pots daily. He also checked for growth and took measurements for a period of 10 days. He measured the height of the plants.

This question is incomplete; the complete part is: what are the independent, dependent, and controlled variables?

Independent variable: ORGANIC AND CHEMICAL FERTILIZERS

Dependent variable: HEIGHT OF PLANT

Controlled variable: Same type of seed, water

Explanation:

Independent variable is the variable that is changed or manipulated by the experimenter. In this question, John wanted to test the effects that organic and chemical fertilizers had on plant growth. Hence, the independent variable is the ORGANIC AND CHEMICAL FERTILIZERS used.

Dependent variable is the variable that responds to changes made to the independent variable. The dependent variable is the variable that is measured in an experiment. In this case, the HEIGHT OF PLANTS MEASURED is the dependent variable.

Controlled variable or Constant is the variable that is kept unchanged throughout the experiment in order not to influence the experimental result or outcome. In this case, the controlled variable is the SAME TYPE OF SEED USED, WATER.
