Lesson summary

Students will investigate the state of the carbon budget designed to reduce emission by 2050. Given the budget and the percentage of emissions used between 2000-2013 students will calculate the rate of use, consider effects of percentage increases and decreases in emission rates for the remaining time frame and the anomalies between scientists and their own predictions. Students will then have the opportunity to use the skills applied through the worksheet the create their own plan for the reduction of emission.

Learning intentions:

Students will...

  • understand how to change quantities to percentages and how to calculate percentage increase and decrease
  • discover the impact of small and large percentage increase and decrease in carbon emissions and the effect of average rates emissions over time.
