Named a prestigious CBC/NSTA Outstanding Science Trade Book, this is a poetic yet accurate description of the life cycle of salmon. For kids, it is fun and eye-opening. For teachers, it is a valuable supplement to a unit on water, fish and ocean animals, and life cycles. Fast-paced prose and brilliant illustrations follow the salmon from their form as eggs in a stream to the wide ocean, eventually making a hazardous journey home to their stream of origin. As in her earlier best-selling book, The Tree in the Ancient Forest, author Carol Reed-Jones uses cumulative verse--a literary technique that is not only enjoyable but suggests how interconnected salmon are with their habitat. At the back is a section on salmon facts and what makes a good habitat for them, teaching the basics of ecology and why clean streams and waters are so important.
