Part 1: Designing Solutions 1. Describe the two phenomena (sub-problems) that caused the contamination of Cleveland’s drinking water.

2. What criteria (data points) were the NOAA buoys collecting to address the sub-problems faced by Cleveland Water? Which of these criteria should have highest priority when determining a solution to the sub-problems?

3. What societal, ecological, or technical constraints should resource managers consider before proposing solutions?
4. Describe the design solution engineers and scientists developed to prevent contamination of Cleveland drinking water. Why did their solution need to address both sub-problems equally?
5. Propose two additional solutions to address the ecological phenomena causing the water contamination in Lake Erie.
Part 2: Claim-Evidence-Reasoning
1. In what ways have the buoys lessened the negative effects of water contamination in Lake Erie.
2. How can unmonitored water contamination affect human populations, farming, and industry in the Cleveland area?
3. What evidence from the video supports this claim?
Claim: Human populations are dependent on technological systems to monitor natural resources.
4. What evidence from the video supports this claim?
Claim: Human populations and societies are affected by the availability of natural resources.
5. A causal relationship means one action or event is the cause of another. A correlational relationship describes a connection between events, but it does not mean one event or action caused the other. Does the video describe a causal or correlational relationship between the health of the Lake Erie ecosystems and human needs and activities surrounding it?
