- Dissolved oxygen is oxygen that is trapped in a fluid. Because many living organisms require oxygen to survive, it is a necessary component of water systems (streams, lakes, rivers, etc.) to support aquatic life. Dissolved oxygen is measured in units of ppm (parts per million). Examine the data in Table 4, which shows the amount of dissolved oxygen present and the number of fish observed in the body of water from which the sample was taken. Dissolved Oxygen (ppm) 0 2 4 6 8 10 12 14 16 18 Number of Fish Observed 0 1 3 10 12 13 15 10 12 13 What patterns do you observe based on the information in Table 4?

The student will collect water samples from the school drinking fountain, home kitchen tap, and a nearby river. To test for lead, the student will use a solution of iodide ion. The student obtains some distilled water (known not to contain lead) and adds the iodide ion; the water remains clear. Next the student obtains a solution known to contain lead from the chemistry laboratory; when iodide ion is added to this sample, a bright yellow solid forms.A student is designing an experiment to test water from various sources for the presence of lead (a heavy metal that can harm humans if ingested).
