The purpose of the plant growth experiment was to test the affect of plant fertilizer during plant growth. The system we were working with allowed us to test the recommended amount and double the recommended amount of Miracle Grow in comparison to a control of an all natural growing plant.

The tools used to collect the data were: a flat ruler, precision ruler, and scale. Each pot was evaluated separately. The contents of the pot were dumped out and each plant...
