The hypothesis is that different plant foods will cause plants to grow at different rates.

You will set up nine identical peat pots, fill them with potting soil, add tomato seeds, and water them with different plant foods. You will also create a greenhouse effect with a piece of glass and a fluorescent light.

You will need nine identical peat pots, potting soil, Miracle-Gro for tomatoes, Shultz-Instant all-purpose plant food, three 1-gallon milk jugs, measuring spoons, a piece of glass, tomato seeds, three Tupperware containers, a pen, and a fluorescent light.

The results of the experiment showed that the plants watered with Shultz-Instant grew to an average of 3.3 inches, the plants watered with Miracle-Gro grew to an average of 3 inches, and the plants watered with plain water grew to an average of 1.5 inches. This data showed that the hypothesis was rejected.

This science project is interesting because it shows how different plant foods can affect the growth of plants.

Experiment variations to consider include testing different types of plants or different amounts of plant food.
