| Explore | We know that germinate means to start growing. Seeds wait until three needs are met to germinate: water, correct temperature, and a good location. In order for a plant go through the process of photosynthesis, it needs water, sunlight, CO2. Photosynthesis produces sugar for the plant to do cellular respiration, which gives the plant ATP energy. Sunlight is important to the process of photosynthesis because it gives the plant energy, and it breaks down the water and CO2 molecules. |

| Research Question | how does the depth of the soil the seed is planted in affect the percentage of germination? |
| Predictions | If the seed is planted deeper into the ground then it will take longer to germinate |
| Experimental Design | Our plan is to put 40 seeds into 5 water bottles at depth intervals of 1 inch(ex: The first water bottle will all have seeds 1 inch deep then the next water bottle will be seeded 2 inches deep.) and place the water bottles out in the open. We will water each seed with 5 tsp. of water in each water bottle; once a day. Every day we will check the percentage of seeds that have germinated and record it on our table. |
| Conclusion | The depth of the soil a seed is planted in won’t affect the percentage of germination. In an investigation we did we recorded the percentage of seeds that germinated. In the end all of the seeds germinated. The seeds planted at a depth of 5 inches still had all seeds germinate even though it was planted deeper than the rest of the seeds. The three things a seed needs to germinate is enough water, good location, and correct temperature. A seed doesn’t need to be planted at a certain depth to complete the process of germination. |
