Mauna Loa in the Classroom

When CO2 collection began at Mauna Loa in 1958, the world was not yet aware of the issue of Climate Change. Years of data collection led to the "Keeling Curve," global collectionss, and comparisons. Through this lesson, students can share in some fo teh scientific discoveries and draw their own conclusions about CO2 levels over time.
Using this lesson in your classroom
Mauna Loa in the Classroom uses real data sets from collection sites in both the northern and southern hemispheres. Students are able to graph data and interpret results to understand trends in CO2 in the atmosphere from 1985-2000.
Seasonal cycles of growth and decay affect the northern hemisphere and southern hemisphere CO2 release and uptake in different ways. The northern hemisphere has more plant material. The atmosphere is well mixed in each hemisphere. Sites from Greenland to Hawaii show similar values and trends.
This lesson provides teachers with an opportunity to discussing weather vs. climate; air circulation around the globe; seasonal affects; and use and interpretation of scientific data bases.
