What it is
- In this math activity, students will solve equations that correspond with a greenhouse gas source and then rank the sources from least emissions to most emissions.
- Students will use multiplication, division, subtraction, and addition skills to determine the ranking for each greenhouse gas source.
Teaching tips
Positives
- Young students will get a sense of which greenhouse gas sources contribute most to climate change.
- The teacher's guide and student handout can be downloaded and used offline or printed.
- The lesson plan includes an answer key.
Additional Prerequisites
- This activity assumes that the students know how to do addition, subtraction, multiplication, and division of whole numbers.
- The teacher's guide features British terms, like lorry (truck) and rubbish (trash or garbage) that some students may not be familiar with.
- The term "greenhouse gas" is not used in the student handout. This activity uses the term "nasty gases."
Differentiation
- Students can solve the equations in groups. Once the equations are solved, they can order the activities together.
- Teachers could use this worksheet for early finishers or as independent morning work.
- Other resources on this topic include this activity that introduces students to the greenhouse gases, this video on the greenhouse effect, and this video on the causes and effects of climate change.
From the scientist review
This resource introduces students to the idea that different human activities create different amounts of greenhouse gas emissions and that we need to reduce some of these activities to help the planet. This resource is recommended for teaching.
