Trade Offs - activities to help students understand the trade-offs made in order to get what they need/want
How the concept of opportunity cost involves
choices about the alternative use of resources and the need to consider
trade-offs
1. explaining why when one choice is made, the next best alternative is not available (trade-off), for example if a student chooses to spend their time (resource) riding their bike after school, they cannot go for a swim (trade-off)
2. explaining why choices have to be made when faced with unlimited wants and limited resources, for example by compiling a list of personal needs and wants, determining priorities (including sustainability of natural environments), and identifying the needs and wants that can be satisfied with the resources available

Diving - science of Margaret River/WA region- geography Tim Winton - biography and we covered his role in helping preserve the Ningaloo Reef. Aboriginal Perspective - the history of the women pearl divers in Broome. It was used in my literacy lessons to also cover vocabulary and the use of imagery. . |

Provide headings found on the pyramid diagram and a triangle for students to work in small groups to arrange Maslow's Hierarchy of Needs in order of priority based on their prior knowledge. Students report back to justify their work. Ask students to colour code the sections of the pyramid to represent importance. Show students the accurate diagram and debate ideas and discuss the colours chosen.

Categorise the needs and wants under the following headings on a chart:
