Quick summary: Students will investigate their usage and disposal of recyclable materials by collecting and analysing data. They will calculate percentages regarding their rate of recycling and apply these figures to average Australian statistics regarding the consumption and manufacture of recyclable materials. Students will be informed of proper recycling habits and understand their responsibility in diverting waste from landfill.
This lesson 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.
