For our science fair project we tried to find out which plant fertilizer would make plants grow the tallest.

The hypothesis for the experiment was that Miracle-Gro, which is a non-organic fertilizer, would make plants grow the very tallest.

We used potting soil, four different fertilizers, a ruler, radish seeds, and water to test this hypothesis.

Miracle-Gro, as we expected, made the radishes grow the tallest because it had the largest amount of nitrogen.

If somebody wanted to do this experiment again then one thing that they could try would be if the amount of fertilizer affects the growth of the plant.
