February manoomin was shorten due to a blizzard, but while at camp students continued work with the LacCore Scientists (macrofossils, diatoms and phytoliths), celebrated Valentines Day by making cards for each other, baking layered cupcakes as well as snowshoeing.  We continue to “connect the dots” through concept maps and note taking. We continue to depend on each other as we learn.

 

Coring Bang Lake

By , November 25, 2012

This years study of manoomin will be based in the core and samples collected during November’s camp. Students observed LacCore/Natural Resources scientists as they collected two cores and  live diatoms (water) from the edge of Bang Lake.

It was an unusually warm Fall day. The sky was a mixture of overcast and sunshine. Even though the lake had frozen over, the thin ice kept students close to shore as they completed their work of gathering and bagging seeds and vegetation samples. By completing a number of prepared questions students were directed in their observation,  research and ID of trees and plants (macrofossils).  Students collected information in a variety of ways – for example, written description a species of trees, bush and grasses were identified by their GPS location, seeds collected and bagged, plant samples collected and bagged, sun-prints, drawings, and digital photographs.

 

 

Diatoms

  Students spent a good amount of time looking through microscopes identifying diatoms using a key found in Third Lake. Visually the diatoms are quite beautiful. Drawing them also is a good way to remember what to look for under the microscope.
