# Junior secondary activities

The activities for the junior secondary students are globally based.

A number of the comparisons are made with Malawi, which is a developing country in the southeast of Africa.

The Your place in the world activities involve creating graphical displays about the numbers of refugees and their source and destination countries, and the eight most significant Australian agricultural commodities for local use and export. The data is presented in a variety of forms, such as tables, maps, comparative column graphs and 100% stacked bar graphs. Students perform a number of percentage calculations.

The About our world activity uses spreadsheets as a tool to explore the effects of changes to global temperatures. Secondary data is used extensively and the emphasis is on its interpretation.

## Your place in the world: Australia’s agriculture

There are many percentage applications in this activity, which uses data about Australian agricultural products. A possible extension involves drawing a 100% stacked bar graph comparing Australian use with exports.

## Your place in the world: Refugees worldwide

The most recent complete data from 2011 allows students to investigate the numbers of refugees, source countries and destination countries of refugees, and some destinations of the majority of asylum seekers.

## About our world: Climate and global warming

The two activities use spreadsheets to model global temperatures since the 1950s and allow students to investigate the possible effects of global warming.
