Abstract

The ozone layer is important for blocking most of the harmful radiation that comes from the sun. You can find maps of the ozone layer and compare different regions of the globe for ozone coverage. Where are the problem areas? Is there a difference in ozone coverage between different hemispheres? Between populated and un-populated areas? In atmospheric regions over land masses or over bodies of water? Some scientists think that aerosols in the air are breaking down the ozone layer. You can do an experiment to find out which products contain these harmful chemicals by researching the ingredients in different products. There are also potential links to methane produced by agriculture, burning of coal and wood, auto emissions, etc. (NCAR, 2006; NOAA, 2006; WMO, 2006)
