| Explore | We learned yesterday that seeds are living before we actually plant them in soil. This is true because if you plant a seed in a damp piece of paper towel and put it in a bag and it will still grow. We also learned that after dispersal seeds remain inactive until it's environment is acceptable for the seed to start growing. Seeds can get eaten or infested with harmful microbes which can eventually kill them. Seeds can be germinated even after 32,000 years. The first stage happens when dry seeds absorb water and begin to swell. The water makes the seed coats softer, which allows moisture to leak into the seed more deeply. |

| Research Question | How does the amount of water affect the rate of germination? |
| Predictions | If water affects the rate of germination, then the seed with some water (not a lot) will help the rate of germination go faster. This is because if you use too much water then you can kill the plant, but if you don't use enough water then you can also kill the plant. |
| Experimental Design | 1. Cut of the top of all five bottles 2. Place six of the thirty buck wheat seeds in each bottle 3. Put a little water in one bottle 4. Add a little more water than the first, too the next 5. Then add more water than the last in each one |
