From experiences outside of school, we have learned that plants require air, sunlight, and water at least. We have most recently learned about the concept of "seed germination," and the factors that goes into it. Finally, we want to discover how to germinate seeds in the most effective way. |
Research Question |
How does pH affect the germination rate? |
Predictions |
We think the stronger alkaline or acidic pH balance, the less effective the seed germination will be, because we know high acidity or alkalinity levels are not good for a seed. |
Experimental Design |
In order to begin our experiment, we need paper towels, baking soda, diluted vinegar, distilled water, a pH meter, and six seeds. Our plan is to wet the paper towels with our different solutions, place three seeds in that condition and place the others in regular conditions, and then observe the growth of all six. |
Conclusion |
We have concluded that seeds can only germinate if they have a neutral pH balance as opposed to alkaline or acidic pH balances. The seeds that had alkaline and acidic pH balances did not change as much as the seeds that had a neutral pH balance. |
