All five grade 8 classes from F.E. Osborne school spent the day at the Weaselhead/Glenmore Park as part of “Fresh and Salt Water Systems” unit of the science curriculum. The trip was led by instructors from the Weaselhead/Glenmore Park Preservation Society who provided valuable knowledge about the Elbow River and the park. The main focus of the day was to use chemical and biotic tests to examine differences in water quality between sampling sites within the park. There was also lots of time to discuss and look for evidence of the effects of human activity on the flora and fauna of the park. For some of the students it was their first visit to the Weaselhead Park and many of them expressed a desire to return with their parents. The trip gave them a greater appreciation of the need to preserve water quality in the Elbow River and we followed this up in class with a project looking and changes in the river as it flows out of the mountains before joining the Bow River.
