Effects of pH on the Germination of Radish Seeds
Results:
1. Identify the relationship between pH and vinegar concentration.
2. Is vinegar an acid Explain how that can be inferred from this activity.
3. Compare your results with the class; were there any differences in the germination or pH
by lab group Is so, speculate on possible reasons for these differences.
4. Under which vinegar concentration did the seeds germinate best Is this consistent with
your expectations
5. Predict how the results of this experiment can be used to explain the effects of acid rain
on our environment.
6. Explain how acidic water can harm aquatic plants and animals.
Conclusion:
Write a lab report using the ―Power Writing Model 2009‖ answering the following questions:
What was investigated
Was the hypothesis supported by the data
What were the major findings
How did your findings compare with other researchers
What possible explanations can you offer for your findings
What recommendations do you have for further study and for improving the experiment
What are some possible applications of the experiment
