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. |
