Hi everyone! A little snow this past weekend didn't stop us from getting out there to explore.
Here's Marina at Upper Treman State Park, checking the acidity of water where young trout from Northeast Elementary were released last month. She is using the same procedure students have been using in classroom aquariums all year. Acidity (pH scale) is an important indicator of stable or changing water quality in spring streams.
Click on the image, or here, to see the full test process, and enjoy that (last?) snow from the comfort of home! We know its supposed to be spring, but winter's last word can still be beautiful!
