RUE Episode 62 Salmon Life Cycle

One of the superb privileges  of living in the Pacific Northwest is witnessing the Salmon Life Cycle! Each fall, Chinook salmon make their spawning migration up the legendary Rogue River and many of them even swim up Bear Creek to lay their eggs among the most populated area of Southern Oregon. We look at a lot of fish in this episode, including the salmon and steelhead that bless the Pacific Northwest and nurture our great forests here.

These students have researched the population trends of a salmon species on the Columbia River over time from 1900 to 1980. Can you see what’s happened to the number of salmon during that time?

Episode Overview

Episode 62 is a wet one, or at least a watery one. We begin the episode with a video about fish – just what characteristics these animals have that allow them to be classified as fish. Then we take a close, more detailed look at a type of fish called a salmon. We feature a video about salmon migration and the importance of this spawning migration to the incredible life cycle of salmon – an indispensable and iconic animal in the Pacific Northwest. After all this input about fish, we look at another water-dwelling category of animal – the amphibian. Specifically,  we learn about the unlikely life cycle of frogs. Here’s where we go to work on language production – discovering words and phrases that can link together facts about the various parts of an animal’s life cycle. We find that we’re sequencing events again, nly this time the events are the different phases of the frog’s life cycle. See the learning materials below.

Language Objective

Use transition words and phases to sequence events.   Describe a multi-step natural process. Describe physical changes that occur during complete metamorphosis.

Academic Content Objectives

Science: Trace the changes that occur during complete and incomplete metamorphosis.  Explain the difference between complete metamorphosis and incomplete metamorphosis. Give examples of animals that go through complete metamorphosis. Give examples of animals that go through incomplete metamorphosis. Trace the sequence of changes that salmon go through in their life cycles. Describe the nitrogen cycle as it relates to salmon in the Pacific Northwest. Sequence the life cycle of frogs. Explain how amphibians are similar to Reptiles and fish, and how they are distinct from reptiles and fish. Name the salmon species that live along the Pacific Coast in the American Northwest.

Geography: Locate the Pacific Northwest on a map. Explain how rivers are important to salmon spawning migrations. Describe the range of salmon throughout their life cycle along the North Pacific Coast. Describe the physical features of Salmon habitat. Name two countries where salmon live in the Pacific Northwest.

We hear so much in this country about conflict between ranchers and government agencies and environmentalist groups that it helps to be reminded that there’s actually a lot of cooperation. As a result of that cooperation, plus the power of the Endangered Species Act, some very good things happen. Watch this video about Ranchers Welcoming Salmon.

In 2021, I found a great Video about salmon entitled Salmon Forest. It’s about the Tongas National Forest in Alaska. Click here the enjoy the video.
