| Explore | Soil structure affects plant growth in many, often surprising, ways. The most obvious effects are on root growth, which is strongly inhibited by hard soil, and which in turn influences the ability of the root system to extract adequate water and nutrients from the soil. Soil is important for plants because it holds roots that provide support for plants and stores nutrients. Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur. |

| Research Question | How does the different type of soil affect the plants growth. |
| Predictions | I predict that the potting soil will grow better then the local soil. I think this because the local soil is more dry then they potting soil. |
| Experimental Design | step 1) We will gather 6 of the same seeds which will be corn. step 2 ) Gather some potting and local soil. step 3 ) gather 6 Dixie cups. step 4) fill the Dixie cup up half way with local soil. Step 5 ) repeat step 4 but with potting soil. Step 6) Put one seed in each Dixie cup. step 7) water your seeds 3 milliliter of water every other day. |
| Conclusion | The claim we can make from our experiment is that potting soil does grow better than local soil, but there could be possible reasons for the local soil not growing. One of those reasons being the fact that the dirt got so dry. Another reason could be that there was diseases and pests in the dirt. |
