Activity Introduction

Quick summary: In this lesson, students are introduced to the challenges of lived experience of homelessness by viewing the opening scene of the Life After The Oasis documentary. They will then explore a range of media articles that explore the issues associated with homelessness and how statistics have been used to present information. Students will use their understandings of homelessness and data representation to manipulate Australian Bureau of Statistics data cubes to calculate five number summaries. An option to use this data to create box and whisker plots has also been included.

Life After The Oasis is a 75 minute documentary that explores the issues, interventions and mindsets associated with youth homelessness in Australia. The film revisits characters and stories from the original 2008 documentary The Oasis and how opportunities and experiences have shaped their lives over the last ten years. Find out how to screen or view the film here.

Warning: The documentary and the clips contained in this lesson, contains explicit language, images of drug use and confronting scenes and may upset some viewers. Teachers should use their personal discretion when showing the documentary. This resource deals with the rising problem of youth homelessness and its associated social and personal issues. There may be students in your class who have experienced some of the issues discussed. You are encouraged to arrive at a set of agreements and ground rules for discussion with your class about the best way to approach the issues being covered in a way that recognises the dignity of our fellow classmates.

  • ... determine the five-number summary (minimum and maximum values, median and upper and lower quartiles) of data sets on homelessness.

Teacher content information: On any given night in Australia, 1 in 200 people are experiencing homelessness. This alarming statistic raises many questions about homelessness in Australia and what is being done by government and non-government institutions to combat the problem. The Australian Bureau of Statistics (ABS) defines a person

Thought starter: Most people who are experiencing homelessness, or at risk of it, remain hidden from public view, living in overcrowded dwellings, rooming houses, caravan parks, or crisis accommodation, sleeping in cars or couch surfing.
