Teaching Tips

Teaching Tips

There are multiple data sets represented in the visualization and thus will need scaffolding by the teacher. This visualization would best be shown to an entire class with scaffolding from the teacher as opposed to students looking at the visualization by themselves. College-level students would not need as much scaffolding. Tutorial on Carbon Tracker is available here: http://www.esrl.noaa.gov/gmd/ccgg/carbontracker/tutorial.html
