In this activity, students interpret graphs from a long-term study of carbon dioxide in the atmosphere of New Zealand. They explore how the interval between samples affects the conclusions we are able to make.

By the end of this activity, students should be able to:

  • draw and/or interpret simple line graphs
  • think critically about the information data and graphs can provide
  • understand the need for the careful planning of experiments
  • understand long-term changes in radiocarbon carbon dioxide in the atmosphere.
