Science Water Quality 8A

Opening Circle 
We circled up for a reading, then carried our probes to the bank of the stream in preparation for the crossing. We split into our two groups from the week earlier. The group that had collected data about riparian vegetation the week prior put on waders and gathered support sticks to prepare to cross the creek, while the group that crossed one week earlier unloaded dry boxes containing Vernier probes and prepared to collect measurements.
Crossing
After crossing the stream, we walked to the spruce grove, a remnant of the grandeur of the pre-fire forest. We discussed the positives and negatives of the fire, how it had affected the forest, and scouted for the upcoming Math Day activities.
Collection
While the other group crossed, we spread our probe stations out along the bank, eliminating bad readings by collecting as many as four measurements for each data point.
Reflection
In the spruce grove, we spread out over its full area, sitting on its many downed logs, exposed roots, and moss-covered banks. We reflected on the crossing, the difference between the two types of forest, as well as the experience of crossing the creek.  At the study site, we reflected on the day, our experience with the Vernier probes, and the learning experience about the quality of the water of Tumalo Creek.
Closing circle
We shared several reflections, discussed the water quality of the stream, and prepared to leave for REALMS.

 





    All you hear is the rustling of the pine needles and breaths overheard from the seemingly heavy wind. But the wind cannot be felt under all the trees and surroundings, unlike the banks, where there isn’t much cover. This area overwhelms you with so little noise replicated loudly throughout the area, but it’s overwhelming in a good way.
    I think it needs variety, because if you only had these spruce groves everywhere, there wouldn’t be room for small growth and it would collapse on itself, so it wouldn’t have stayed healthy for long, before the fire. I think it’s more healthy now, but the grove could have more area to create variety.
