| Explore | They need c02, water, soil, and sunlight energy. They use these to perform photosynthesis. They use glucose and 02 to perform cellular respiration to make ATP energy. |

| Research Question | How does changing the amount of water the plant gets change the rate of growth? |
| Predictions | Callen - If we use 30 drops of water then it will germinate the most, this is because not enough water will kill it but too much water will drown it. Everett - Jayson - The Seeds that get 50 Drops will germinate fastest. Could drown though, so I'd say 40 might have some better odds. Sam - If we increase the amount of water for seeds in different petri dishes, then the plants will germinate faster with the middle amount of water. |
| Experimental Design | Procedure: 1: get 5 petri dishes 2: put one piece of paper towel in each dish 3: add 9 buckwheat seeds to each petri dish 4: add 10 drops of water to the first petri dish, 20 to the second, 30 to the third dish, 40 to the 4th, and 50 to the 5th. 5: measure length of roots once for everyday for 5 days |
| Conclusion | 50 drops grew the most |
