| Explore | Germination is when a seed starts to grow. Seeds will stay dormant until they have water, correct temp(warm) and location. |
|---|---|
| Research Question | How does the type of soil affect the percent of germination. |
| Predictions | Some of our predictions include... 1.If the soil is fertilized and moist then more seeds will germinate because it has the conditions it needs to grow faster. |
| Experimental Design | 1.Clean a clear plastic drink bottle and cut off the top half. x5 2. Line the bottom half of the bottle with wet paper towel folded to form 2-3 layers. 3.place clean sand at the bottom to hold the paper towel in place. 4. Distribute 10 seeds into the 5 bottles 5. Place a soil in the bottle 6. Place under grow lights for 8 hours (Mon. through Fri.) 7. Put ml of water in the soil Variables tested will be independent= Type of soil Dependent= The amount of seeds that germinate Variables to control= Water,light,Temperature We will record our data on a table made for our question. |
| Conclusion | claim: If the soil is fertilized, then seeds will germinate faster. evidence: The seeds that were in fertilized soil, 6 of them germinated. When the seeds were in any other mixture, the most seeds that germinated was 2. reasoning: Fertilized soil had the most seeds that germinated because it is a silt soil. This means that the soil drains water faster. This gives the seeds enough water to survive without drowning. We gave our plants a lot of water so some of them drowned. I don't feel confident in my results. We changed the amount of water 3 times and the seeds were not at the same depths. |
