Worksheet: Applying The Scientific Method

Dr. Lina Reye wanted to answer the problem; “What effect does additional nitrogen have on plant growth?”. She set up an experiment in which she planted bean seeds in two groups, A and B. After the seeds germinated, Group A was given an application of fertilizer with additional nitrogen. Group B was grown under identical conditions, except the fertilizer it received contained no additional nitrogen. Dr. Lina Reyes measured the height of the plants for one month.
