| Explore | We know that seeds need water to grow but how does the acidity affect the germination rate |
|---|---|
| Research Question | Does the pH of Soil affect germination rate? |
| Predictions | We think the acidic soil would be bad for the seeds because acidic things also can affect people |
| Experimental Design | Step 1. Mix up the diluted vinegar water, diluted baking soda water, and controlled distilled water. Step 2. soak soil with each of the fluids. Step 3. Bury the seeds in and put soaked soil. Step 4. Put each in container separately labeled. Step 5. Wait and observe the germination rate with a soil pH. Step 6. Check the ph meter often. Materials: Water, Baking Soda, Vinegar, Soil, Airtight container, and Seeds |
| Conclusion | So in the end, the only one that had germinated was the baking soda alkaline one. What we took from this project is that a more based alkaline leveled seed can germinate better that a higher alkaline one. We collected and decided that the acidity from the apple cider vinegar had corroded the seed as high acidity affects people. Improvements that we could make would be watching the watering levels since we had high levels of mold in each sample and if we had been more careful we probably could have gotten more answers. |
