| Explore | We know that plants grow in all different conditions. Some plants need more rain than others. Some plants don't need soil but others do. Some plants cannot tolerate certain temperatures. Some plants need a lot of sun and others do better in less sunlight. We are interested in light levels specifically but we have determined that this would be too hard to control with our limited equipment. We are also interested in how water affects germination speed. |
|---|---|
| Research Question | How does the amount of water a seed is given affect it's germination speed? We know that all seeds need water to germinate in order to activate the enzymes to trigger growth but we are wondering if the amount of water impacts the speed of germination. |
| Predictions | My prediction for how the amount of water affect the time from planting to sprout is, if the seedling does not have enough water, it may not sprout as well or it may die. If the seedling has too much water, it may not sprout as well or die. The key is to find the right amount of water so it can sprout. well and become a beautiful plant. |
| Experimental Design | We keep 16 seeds within 16 test tubes with the same air quality, sunlight provided, and soil. The amount of water in each pot is the only difference. 4 seeds will have no water, 4 will get 1ML of water, 4 will get 2ML of water, and 4 will get 3ML of water every 4 days. We will observe how water can affect the germination process every day. By watching to see if they germinate every day. |
| Conclusion | Our final claim is that water is a key component of a plant’s life and germination. Not enough water could very much affect the plant's germination rate by not allowing for germination to start. We make this conclusion because a greater percent of our seeds that were given the most amount of water (2-3 ml) germinated first, while the other seeds (0-1 ml) took a longer period of time to germinate or they never did germinate. We think this happens because when the plant is not given enough water it does not have enough support its growth. We think this happens because without water it is very likely that the seeds will die or not grow and with water the seeds grew and did better than the seeds without. To better support our conclusion we would give the seeds more time to grow so that we can see which seeds grow and which seeds take longer to grow. |
