Teacher Activities: Building Background
Links to Students’ Past Experience: Discussions relating to their knowledge of the 4 major oceans, their size and
location, their features, and the technology we use to study the ocean floor. Discuss students trips to the ocean and
their knowledge of it’s features and contents. Why is the ocean blue?
Teacher links to Prior Learning: We’ve briefly learned about oceanography in Ch 1. Discuss the fact that the floor of
