Our mission was to find the D.O. levels in three seprate rivers.we did our job by:

Step 1.Insert the D.O. probe into the vernier lab quest.	Step 2.Turn on the lab quest and bring up the chart.

Step 3.Swirl the probe in the water for one minute.

Step 4.Repeat step three twice.

Step 5.Add the three tests together and divide by the number of tests.

And that's how we got our data for the rivers.
