1. The analysis of water in a lake or stream depends upon more than one field of science or body of knowledge. Suppose you stumble across a portable water-testing lab on a riverbank, and you find two testing stations: (1) a light microscope and glass slides; and (2) a package of pH (acid/base) test strips and a digital thermometer. But you find no scientists. Match each testing equipment station to the field of science to which it belongs, and hypothesize what is being tested in each station. (6 points) 2. Technology has affected society by causing radical changes in how people live. For example, the use of pesticides has increased the amount of food available to people. Describe another example of how technology has changed the way people live. (5 points) 3. Describe what eDNA is. Evaluate the use of eDNA in the monitoring of a difficult-to-track species of fish in a river. (5 points) 4. Investigate energy in a prairie ecosystem. a. Use an example to describe how the first law of thermodynamics is observed in a prairie ecosystem. (2 points) b. Compare the albedo of the prairie to the albedo of another type of ecosystem or biome. Be sure to mention which is higher. (2 points) c. How are local energy systems in the prairie related to global systems
