| Explore | Trees, instead of using cellular respiration, go through photosynthesis to produce glucose or "food" for them selves. |

| Research Question | Does the amount of water a plant gets affect how fast it germinates? |
| Predictions | If you add too much water the plant would drown then it cannot grow, but if you don't add enough water the plant won't have enough moisture to grow and germinate. |
| Experimental Design | 1: place 5 Buckwheat seeds in each bag 2: Measure the water for each of the bags 3: Start the expirement/ start measuring the rate of germination. |
| Conclusion | The more water that you add to a seed in a bag with paper towel, the faster it will germinate. When we had 0 drops of water, there were 0/5 seeds that germinated. For 20 drops of water, there were ⅖ seeds that germinated. For 60 drops of water ⅘ seeds germinated. Finally when we added 120 drops of water, all 5 seeds germinated. The 0 drops of water did not grow because there wasn’t enough water to soften the shell of the seeds and give the necessary amount of water to produce the energy that seeds need to grow. The seeds that had 120 drops of water added to their bag had enough water to have the seeds shells soften and have leftover water to produce energy with the contents already inside the seed and grow the plant. |
