Turbidity

Today students considered another factor that may be causing problems for fish in Gray Area.  With logging an active business in the area, some of the rivers were looking a little dirty.  Students used secchi disks to determine the clarity, or turbidity, of the water in the various lakes and rivers in the area.  They then examined the sediment files to understand the effects of erosion and high levels of sediments on the organisms living there.

We also did some work in our data unit for math and students examined and evaluated different graphs and tables for recording survey results.  They also created questions that could and could not be answered from these graphs.  As we continue with graphing, students will be discovering effective survey questions and techniques and create their own survey tool to collect, represent, and analyze their data.

We got to enjoy some sun and read Listening to Crickets as well as take some time to reflect for our end of the year evaluations.  Second graders prepared for their field study next week by looking at goals, expectation, and vocabulary for the trip!  Continue to practice our terms at this link!
