| Explore | Plants grow well in fertile soil, and won't start to grow until the conditions are perfect. They can survive in a dormant state until they are ready to grow. Plants use photosynthesis to make food for themselves. They use sunlight energy to turn water and Carbon Dioxide into Glucose and Oxygen. Using the outputs for photosynthesis, cellular respiration makes Water, CO2, and ATP energy, which it uses to power the plant cell |

| Research Question | How does the amount of water affect how fast a buckwheat seeds germinate? |
| Predictions | If we add more water to the seed, it will germinate faster. But if we add too much water, the plant might die. We think this because a plant needs water to grow, and if it doesn't have enough water, it can't prosper. At the same time, if the plant has too much water, it could drown or get waterlogged. |
| Experimental Design | 1.) Each student gets a paper towel in which they put 10 buckwheat seeds spread apart in the paper towels. We then put the paper towels in a sealed zip-lock bag. 2.) Each group member gets a designated amount of water and applies it to the paper towel evenly. We will do this daily. Cooper-5 mL Josh-10 mL Brock-13 mL Rowan-16 mL 3.) At the end of the week we will measure how tall the plant is (not including the seed) in mm, an record our data. |
| Conclusion | Question: How does the amount of water, affect the growth of a buckwheat? Claim: If you add too much water, it may stunt the growth of the plant, or waterlog it, which will result in killing it, but if you use too little, the plant may not grow at all. Evidence: When I used 10 mL of water, my plant was growing good, and was healthy, but if you were to add 5 mL of water, like one of my partners did, the plant wouldn’t grow very much. So I think you should add 10 mL of water or more. Reasoning: The reason for this, is seeds absorb water, which activates the biochemical mechanisms required for germination. If/When the seed absorbs enough water, the embryo (the shell of the seed) will burst, starting the germination process. |
