Inspiring the Next Generation of Biologists

Inspiring the Next Generation of Biologists at the American River

March 23, 2018

Bright and early, nearly 60 first grade students from Dewey Elementary school began to bounce off the buses and race towards the roaring American River. Armed with their very own biologist kits, the first graders begin to explore the river and gain a hands-on experience of what the life of a field biologist entails!

For the fourth year the Water Forum, in collaboration with The Nature Conservancy, U.S. Fish and Wildlife Service, CBEC, and C.A. Department of Fish and Wildlife, seeks to provide an immersive learning opportunity for local first graders to connect with their environment and to support an early interest in science. Through a series of stations where the students participate in a dissection, substrate sorting and red building, seining, bug identification, and water quality testing, the students learn:

  1. What fish make the river their home and what those fish look like
  2. The diet of a young salmon
  3. The criteria for good spawning habitat
  4. The criteria for good habitat for young fish
  5. How to keep the river healthy for salmon and other living things

The Water Forum looks forward to continuing this partnership and inspiring the next generation of environmental stewards!
