| Explore | Germination is a process a seed goes through to start growing. Before this happens the seed is dormant. When the seed starts to go through germination a cotyledon appears which is the leaves that come out. |

| Research Question | How does the type of sugar in water affect the germination of a corn plant? |
| Predictions | We think that it won't make a difference whether we use sugar in the water or not. |
| Experimental Design | 1. Get Materials ( Granulated Sugar, Corn Seeds, Potting Soil, Water). 2. Make the Growing Pod (Half of a water bottle) 3. Plant Seeds one inch in the soil 4. Dissolve one tablespoon of each type of sugar in the water 5. Pour the dissolved sugar in the water over the seeds until the soil is moist. 6. Repeat 5 daily until the plants break the surface. 7. Upon the plants breaking the surface, we will record how many days it took for this to happen. |
| Conclusion | A sugar-water corn plant will not germinate as fast as a regular watered corn plant. This is because as you can tell by our results the sugar plants didn't grow while the regular ones did. For example, on day four all seeds in the plant "water 1" were all germinated while 0 from "sugar 1" had germinated. We got these results because of osmosis. Since osmosis occurred our sugar plants didn't get enough water and died while the water plants were still growing fine. |
