Suggested age for this exercise is 16 and up, but this is because of the short story example. Teachers of younger grades might enjoy the story, and use the ideas to pass on to their students.
This is a research and creative writing project. Students research the lives of critters they know nothing about, and bring them to life though creative writing and personification!
The story example is about a salmon couple as they go up a river to spawn. Physical changes happen to both of them. There are dangers that they work together to avoid. The salmon secret is that salmon can always find the perfect place in a river to lay their eggs.
