The students were well-prepared by their teacher, Sally
Catanese, prior to the field trip. They studied the life
cycle of salmon, learned associated vocabulary words,
and incorporated terms into their weekly spelling tests.
“Did you know that the salmon in this river came from
Lake Michigan?” explained student Tiegan Ziehm. “They
were born here, and then a few years later they come
back to the same place they were born and they lay their
eggs here. The
salmon have really, really good senses of smell and they
smell their way back home.”
While at the weir, DNR personnel gave students an
up-close look at adult Chinook salmon and the spawning
process. At the end of visit, the class was given some
fertilized eggs to take back to their classroom fish
tank.
Student Cadence Mcwain described how the salmon lay
their eggs. “The salmon lie on their sides and wag their
tails to make a hole to lay their eggs in,” said Mcwain.
“The hole is called a redd, and after the eggs are in
the hole, the fish use their tails to cover up the eggs
with gravel. The eggs stay under the gravel all winter
and hatch in the Spring.”
When Spring comes, this class of Onekama students will
take another field trip – this time to release the
salmon from their classroom tank into a local creek.
Until then, students will wait and watch their classroom
tank to see the wonders of science hatch right before
their eyes.
