Carbon dioxide and methane are our two most prevalent human-contributed greenhouse gases. This holstein cow is one of many huge contributors to our methane production. Let students calculate percentages of greenhouse gas production from cars, cows, and people. We've got flatulence humor, percentage calculations, and global warming education in this activity.
For members we have a Word doc and solutions.
