  1. Adventure Learning (AL) on Lake Fernan Mr. Anderson & Mr. Knigge Summer 2014

  2. Question: Does stream velocity affect macroinvertebrate quality?

  3. Hypothesis: • If stream velocity is high, then macroinvertebrate quality will be high.

  4. Procedure • GPS location of site tested • Measure stream velocity of three sites within our GPS location • High velocity • Medium velocity • Low Velocity • Using the ball and string method, we tested stream flow • Use kick net and shovel to collect macros at each flow site • Identified the quality of the macros collected from 3 flow sites based on tolerance for water quality

  5. High Flow Rate--Riffle(1.13 m/s)

  6. Medium Flow Rate– Run(0.6 m/s)

  7. Low Flow Rate– Glide(0.02 m/s)

  8. Collecting Our Data!

  9. Stream Velocity Pictures Medium Velocity High Velocity Low Velocity

  10. Results

  11. Results—Graph

  12. Data Analysis • High Flow • Lots of HQ organisms and lots of LQ organisms • Medium Flow • Predominantly MQ organisms • Low flow • Mainly LQ organisms, but holistically few organisms

  13. Conclusion • Our data supports our hypothesis • More HQ organisms were present in the high flow rate AND a larger population of organisms was discovered • As anticipated, the low flow rate site had fewer HQ organisms AND a smaller total population • In our hypothesis, we did not anticipate the large number of LQ organisms in the high flow rate site • Future Research/Question: In a high flow rate site, with lots of HQ macros would we see a trend in the number of LQ organisms?

  14. Adventure Learning at THS • Outline/Intro Spirit Lake Quality Project • Teach Content of Ecology • Show/demo IdaH2O processes • Test • Determine teams and assign roles based on test results • Practice processes • Field Day • Gather data and enter into HIS • Prepare Presentation • Spirit Lake Water Quality Summit • Invite community, experts, students, teachers • Confluence Project??
