| Explore | We know that for a seed to grow into a plant, it needs water, sunlight, and carbon dioxide. These are the three inputs that also help a plant to produce outputs. Such as glucose and oxygen. Plants have cells that help them to reproduce and produce more seeds. The seeds can fall off the plant and travel long distances over time. Then once they are deep enough into the ground they will start to grow. First their root will come out and then the seed will sprout. Over time , the seedling will consume the 3 inputs and grow into a healthy and tall plant if the conditions are right. Then everything will happen all over again. Just like the circle of life. |

| Research Question | How does the amount of water given to the plant affect how big the plant grows? |
| Predictions | We believe that if we give the see too much water it will drowned. If we don't give it enough water it will dry out, so we need to find the perfect amount of water to give to the seed. |
| Experimental Design | We will each have 4 plastic baggies with two pea seeds in each bag. Each bag will have a certain amount of water that will be given to that seed (1/2 teaspoon, teaspoon, 1/2 tablespoon, and tablespoon.) The two seeds per bag will lay on a piece of paper towel inside the plastic baggie. That way the paper towel will absorb some of the water to keep the seed moist. |
| Conclusion | We can now finally say that giving a Tablespoon of water will help a seed grow healthier and faster. We can say this because the pea seed that was watered with a Tablespoon had the longest root. This is probably because it gives the seed water and it wets the paper towel which will keep the seed damp. The data we collected helped us to see that when we don't give the seed enough water it slows the process of germination down. With the measurements we chose to give the seed didn't make it drown or take on too much water. We could add larger amounts of water measurements to see how much water would be too much. |
