| Explore | They need water to survive. They conduct photosythesis and cellular resperation to survive. They grow from a seed in the ground. They absorb nuitrients from soil. |

| Research Question | How does the amount of water affect the speed of the germination process. |
| Predictions | I think that the larger amounts of water are going to make the germination process speed up. |
| Experimental Design | Step 1. Put 1 paper towel in each of the petri dishes. Step 2. Lay 8 pea seeds in each of the 6 petri dishes. Step 3. Pour 0 mL of water on #1. Step 4. Pour 5 ml of water on #2. Step 5. Pour 10 ml of water on #3. Step 6. Pour 15 ml of water on #4. Step 7. Pour 20 ml of water on #5. Step 8. Pour 25 ml of water on #6. Step 9. Observe the seeds and root length. Step 10. Place in medium light. Step 11. Repeat steps, 3,4,5,6,7,8, and 9 for 7 days. |
| Conclusion | Claim. The more water you give a plant the faster it will grow as long as its not too much. Evidence. The seeds that got 0 Milliliters of water had no growth and the seed that got 25 Milliliters of water had and average root length of .52 inches. However the seeds that should have gotten 15 Milliliters of water had almost 2 times the growth of the 25 Milliliters of water. I think that that happened because a lot the seeds with 25 Milliliters of water had died from mold and others damaged from it. On the other hand, the 15 Milliliters of water had no mold on them allowing them to grow faster. Reasoning. Plants need water to live and wont germinate unless they have some form of it and enough of it. They need water to grow and is they are able to get that water faster then they will grow faster. On the other hand mold can kill seeds and it will take even longer to grow and even die because of the mold. When this happens it is called damping off and is usually a death sentence for your plants. |
