Short answer: A woman who moved from the midwest to the desert noticed that her rose plants were not
flowering. She wanted to see if planting the roses in richer soil would help them produce flowers. She
knew that potting soil had many plant nutrients that were not found in the sandy soil of the desert. She
decided to add some potting soil to one sandy area of her yard. She predicted that the rose bush planted in
the area with sand plus the potting soil would produce more flowers than the area of the yard with only
sandy soil. The table below shows how she set up her investigation:
Plant
Rose plant # 1
Rose plant # 2
Type of Soil
