Engage students in examining the life cycle of salmon. Ask students to describe and/or illustrate the changes that take place as the organism develops. Invite students to present and compare their reports (diagrams, posters, oral presentations as well as written reports).
Teachers may ask students to create a chart of the changes which occur during the life cycle of selected organisms. The chart might also show things which remain constant.
Encourage students to pose a variety of questions about the development of animals (e.g., “I wonder …..?”). These questions can be the impetus for more extensive student research projects.
