Lesson plan:

View Dead Ducks

After viewing draw attention to the problem which is highlighted in the first part of the episode - the effects of the introduction of foreign substances into waterways.
Discuss the ways in which people use water and the possible effects of the introduction of foreign substances. Draw a simple diagram of the water cycle and discuss how people are part of the water cycle.

Explore the claims of ownership

This episode also raises issues about the discovery, ownership and disposal of historic materials. The children assume that they will own the gold if they discover it. There have been quite bitter disputes and court cases about the ownership of material from Dutch shipwrecks off the West Australian coast between the discoverers and the government.

Ask students to put forward arguments which could be used to support the ownership claims of different groups: the government, the discoverers and the descendants of the original owners of historic material. At the end conduct a class vote or decide on a compromise arrangement.
