| Explore | Plants are multicellular plants that do photosynthesis to create food. They use roots to gather water and nutrients from soil and their leaves collect CO2 and sunlight. All plants spread their seeds in different ways including air, animals, etc... |

| Research Question | How does the amount of water a seed receives affect how quickly it germinates? |
| Predictions | If a seed receives more water, then it will germinate faster than a seed that receives less water. |
| Experimental Design | 1. Separate 12 seeds(peas) into 3 petri dishes 2. On day one, water 1 petri dish with 10ml of water from sink 3. Also on day one, water the other with 20ml of water from sink 4. Also on day one fill the last dish with 30ml of water 5. Observe for the next few days and record data on how many 6. Water them again with the same measurements 7. Observe and record data on how many peas have germinated 8. Do this 3 times |
| Conclusion | The more water a seed receives, the faster it will germinate. In our investigation, the seeds with 3ml of water germinated faster than the ones with 1ml and 2ml of water. They were also the only ones to germinate. 4 out of 12 of the seeds with 3ml sprouted and they were all on the last day. We observed a small crack in one of the 3ml seeds that sprouted on the first day as well. This still proves my claim because the other seeds didn’t germinate at all, so the ones with 3ml still were the fastest to germinate. We also observed the small crack in one of the seeds that germinated. This proves that the 3ml seeds were also the first ones to start the process of germination. I’m sure if we had more time, the other seeds would have grown, but still slower than the 3ml seeds. There was not enough water for the others to set off the biochemical mechanisms necessary for germination. |
