| Explore | Well known facts about plants are that the main necessities for plants to live are water, carbon dioxide, and water, but they also need proper nutrients from the soil to grow correctly to for fill their elemental nutrients which are completing their life cycle, biological function, and cell growth and structural support. Plants get their CO2 and Water through stomata and through them they release O2 and water. The amount of stomata varies depending on the plant such as tropical plants have more stomata then arid plants due to the fact that arid plants don't want to risk to much lose of water than tropical plants do. Plants obtain their nutrients through their roots which they suck up. Although we wonder how nutrients affects plants, does an abundance of nutrient allow the plant to grow up healthier or does it overdose them and kill them faster. |

| Research Question | How will high and low nutrient levels effect the length of the Bassica Rapa roots? We were wondering about the function of the roots and how it alters in different plants and climate, not a lot is known about roots, and it is a question we can learn and benefit from. We know that roots are one of the main sources to taking nutrients to plants, and our topic was "how does nutrient levels effect the growth and development of plants?" and we want to specify and choose a part of the plant that level of nutrients effects. |
| Predictions | Our hypothesis was that the lower nutrient soil plants would have longer roots because they would have to search for nutrients deeper in the soil causing it to put more time into growing the roots other than growing the plant. While the plants in the higher nutrient soil will grow a little more outward and be smaller than the low nutrient plant because it puts energy into growing the actual plant instead of the roots. |
| Experimental Design | We will be planting 12 Bassica rapa plants, six of the plants will be put into a homemade plant holder that has a low amount of fertilizer, and the other six went into a plant holder that has a high amount of fertilizer, and see how it affects the plant. We are testing how long and big in diameter the roots will get after they die. We were going to measure over time but we felt that it would be too risky to damage the plants and or roots. We will record this by after they die. We will be carefully dig them up and measure the length on both high and low. |
