Last Friday, the 13th (!), we went over to New Hampton fish hatchery.  We stripped male brook trout of milt and female brook trout of eggs.  Did you know that a female brook trout produces 400 - 600 eggs per year? The hatchery has 1.3 million eggs incubating at any one time.  The eggs have an 85% chance of survival.
In addition, we climbed a mountain with Mr. Wetmore and discussed the watershed.  Did you know that there are many factors that contribute to the health of a river?  Human impact, erosion, and farming are a few examples.
With Ms. Allen (Petunia), we made river art to demonstrate out knowledge of the riffle, the run, and the pool.  The riparian zone is the area that surrounds the river. It prevents the banks from eroding, protects the river from trash, and keeps the water shaded and cool.
