| Explore | We know that they're living things with cells and need food, water and sun to survive. They also come in many different shapes, colors, and sizes and produce different things that humans may use or avoid. Some can heal while others can kill. We know that plants are alive because they have cells and reproduce. They also go through different stages of a cycle to get to where we're more familiar to. There cycle is there live though much shorter than ours. We also know from class that the seeds don't needs soil to live and when they leave their plant find many different ways to travel. I think that this question interests me because I never really knew how much water a plant needs to survive and flourish. |

| Research Question | How does the amount of water effect how fast the seed germinates? |
| Predictions | If we put lots of water, some water,and little water the seed with some water will germinate quicker because it has equal amounts of air and water. Some people in our group think that the seed with lots of water will germinate quicker because they think the more water will speeden the germination process. |
| Experimental Design | 1. we squeeze 3ml of water onto a paper towel 2. we squeeze 4.5 ml of water onto another paper towel and 6ml of water onto another 3. put each into 3 separate pitri dishes and put 3 seeds of nasturtium, corn, and round radish, , into each pitri dish. 4. everyday observe the seeds and record observation and write how many days it takes for the seeds to germinate. |
| Conclusion | The less water you give to your plant the better it'll grow. I know because in our investigation we had 3 pitri dishes that different amounts of water given to the seeds ( 3ml, 5ml, 8ml ). on days 6, the last day of the investigation, the 3ml seeds had 39 germinate and the 5ml seeds had 38 germinate along with the 8ml. So the 3ml had one more seed germinate than the others. This happened because when the seeds are in the germination process it absorbs water making the seeds bloat. The endosperm nourishes the embryo with water to create food. If there's to little water the seed isn't nourished so it won't germinate. but if there's to much water,mold will start to form on the shell and roots. Cutting off the oxygen supply and making the roots decay and rot. We saw a lot of that in the 5 and 8ml so we think if we went lower than 3ml, the seeds might not of germinated at all. So the 3ml was like the happy medium between to little and to much. |
