Lesson 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 materials from landfill.
Learning intentions:
Students will...
- understand and become familiar with proper recycling habits
- be able to calculate and apply percentages to solve problems related to recycling (focus for Years 7 and 8)
- understand how to collect and use data to solve problems related to recycling (focus for Years 9 and 10)
- understand the effects of sending recyclable material to landfill
Success criteria:
Students can...
- identify the recyclable materials they are using on an average day
- calculate percentages, averages and proportions in a problem-solving context
