| Explore | I know that plants germinate and grow. Plants also need water, sun, and good location to grow. Plants also give us oxygen for us to breathe in. Also, they take in carbon dioxide. Also, they can give us food so we can eat so plants are very important. |

| Research Question | How does the amount of water affect how fast corn seeds germinate? |
| Predictions | I think if you put in a lot of water then it will die, if you barely put in barely any water it will die, and if you put in the right amount, it will grow. I think if you put it in a shady location, then it will not grow as fast then in a sunnier location. |
| Experimental Design | Step 1: Get materials. Step 2: Put paper towel in a plastic bag. Step 3: Place seed on paper towel in bag. Step 4: Do that twice. Step 5: Water them daily one with more water than the other. Step 6: Measure the data and find the one that grows faster. |
| Conclusion | Claim: The bag with more water germinated more on day one than the other bag with less water on day one. Evidence: The bag with more water started germinating faster (which had all 11 seeds starting to germinate.) on day one and the bag with less water which had 5 seeds starting to germinate. Reasoning: The results turned out this way because, the embryo in the plant seed absorbs water witch enlarges the seed until it cracks open, so the seeds with more water started germination faster because they absorbed more water to enlarge them quicker. The seeds with more water also didn’t die of too much water because their hard shell closes when they have enough water so they don’t get too much. The ones with less water germinated later, because they didn’t have enough water to crack open the shell to start the germination process. Our data supports my prior knowledge and it is what I expected. Our investigation was a fair test because we had everything measured and we did multiple data recordings. A future experiment we could do is measure how fast different seeds start the germination process. |
