Activity Introduction

Quick summary: In this lesson, students will collect data on their own recycling habits and use this to evaluate and reflect upon recycling and waste across the school.

This activity has been developed in partnership with Visy. For over 60 years Visy has been striving for sustainability, reducing the amount of waste going to landfill by collecting recyclable materials and recycling them into new paper and packaging products.

Learning intentions:

  • Students will be able to use arrays to find the approximate amount of recycled material that could be recovered by their class each week.
  • Students will understand which waste items can be put in the recycle bin.

Success criteria:

  • Students can collect one day’s data then use an array to predict a weekly total.
  • Students can collect data about the recyclables that are in the class bin.
  • Students can use the data found to work out how many recyclables could be going to landfill.
  • Students can name the five main groups of recyclable materials (paper and cardboard, aluminium, steel, plastic and glass).

Teacher content information:

Almost everything we do in our daily lives creates waste. We can describe waste as something we no longer want or need. The food and drinks we consume, the clothes and cosmetics we wear, the transport we take, the stuff we buy, the energy we use in our homes and workplaces – all these things have wa
