The questions below are suggested for help in determining a
hypothesis for the project, follow-up discussions or further
exploration. Students could address some of these questions or try to
make comparisons of their own and include in their Final Reports.
- How did the Dissolved Oxygen level of your water sample compare to
the BOD level? Did you see any relationship between the
two? If so, what was it?
- How did the Dissolved Oxygen level of your water sample compare to
the Carbon Dioxide level? Did you notice a lot of plant life
in the water? How might this relate to Carbon Dioxide levels?
- Is there a relationship between Dissolved Oxygen levels and the
types of plants, animal, or other organisms you observed in the
water? If so, describe the relationship.
- Is there a relationship between BOD levels and the types of
plants, animals, or other organisms you observed in the water?
If so, describe the relationship.
- Do you think that your water source is a good environment for
organisms to survive based on pH levels? Why or why not?
- Is there a relationship between Nitrate and Phosphate levels and
observed algae or plant life in the water? If so, describe the
relationship.
- Is there a relationship between Turbidity level and the type and
variety of organisms observed in the water? If so, describe
the relationship.
- Is there any relationship between Dissolved Oxygen levels and
Turbidity? Between BOD levels and Turbidity?
- Look at the database of results. Do you see a relationship
between Dissolved Oxygen levels and water Temperature? If so,
describe the relationship.
- Look at the database of results. Do you see a relationship
between Temperature and BOD level? If so, describe the
relationship.
- Did any of your results indicate poor or good water quality?
If so, which ones? Explain your reasoning.
- Are any of your results not what you expected them to be?
Which ones? Explain your reasoning.
- Look at all the schools' data collected for this project. Do
your relationships hold true for other school's results as well?
- Pick one other school collaborating in this project and make a
comparison between your water supplies.
