| Explore | Plants can grow without soil but they need the nutrients that they provide, they would need to find some other way to get the nutrients.Plants can grow with too much soil but it can be hard for it grow and some will not even grow. But a plant can grow with too much soil. Soil provides anchorage for roots, they hold water and nutrients. Healthy soils are essential for healthy plant growth, human food, and clean water.The three main nutrients that plants need are nitrogen, phosphorus, and potassium which are the main nutrients found in soil. |

| Research Question | How does the amount of soil affect how much corn grows? |
| Predictions | We think that the normal amount of soil will make the plant grow the most. We think that because if you have to much nutrients from the soil it will probably be bad for the plant and the same with too little. |
| Experimental Design | For our materials we will need 9 of the same containers, soil, and 9 corn seeds.Our plan is to put different amounts of soil in each container (little=up to 2 rings, normal=4 rings,a lot=5 rings), then put a corn seed in each container. Then we will give them all the same sunlight and water and see which one grows the most and healthiest.We will repeat this experiment 2 times. |
| Conclusion | Trial one with the smallest amount of soil grew the shortest and our tallest was trial two large at 18 cm. |
