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.

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

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.
