Teaching Materials
Positives
- Students can practice the meaningful skill of interpreting data.
- There is enough data for students to work in small groups and have each group contribute a different graph to the class.
Additional Prerequisites
- Students should know how to plot data on a line graph.
- Students should know what CO2 is and how it is released into the atmosphere.
Differentiation
- Younger students may need to graph the data or interpret the graphs as a whole class.
- After looking at the data, students in science classes can discuss the effect CO2 and other greenhouse gases have on the atmosphere and our planet.
- Language arts students can use their observations of the data as evidence in an informative essay about atmospheric CO2 levels.
- Students can graph other climate-related datasets, such as global temperature rise, sea level rise, or phenological data.
