Positives

• The graphs are simple and easy to read.

Additional Prerequisites

• Teachers may want to provide some background about nitrous oxide's relationship to climate change.
• Teachers should clarify the units mole fraction and parts per billion if students are unfamiliar.

• If the technical reading is distracting, there are PDFs of the graphs and data that teachers can use instead.
• The data is also downloadable in CSV files.

Differentiation

• The reading is very technical and is probably most appropriate for upper high school students.
• Students can work independently or with a small group to create a list of noticings and wonderings about the data.
• Other related datasets include nitrous oxide emissions, per-capita nitrous oxide emissions, and nitrous oxide emissions by sector.
• If teaching about greenhouse gases in general, check out this video by Hot Mess or this lesson by King's Center for Visualizations in Science.
