There is so much media hype and public misunderstanding regarding the issue of climate change that advanced students need to be equipped to sort through the information available, find data from appropriately moderated scientific data bases, and learn to support their views with good scientific evidence rather than emotion. This lesson provides the outline for giving students some preliminary
How can the ocean be colder than 0 degrees C, the temperature at which water freezes? As it turns out, the concentration of the particles (in this case, the ions from the salt) in ocean water lowers the temperature at which the saltwater will freeze. Students will learn how ocean water freezes at a lower temperature than freshwater by
This data plotting lesson compares different stratospheric ozone data collected at the South Pole in September 1969, September 1998, September 2008, January 1999, and January 2008. This ozone comparison activity allows students to make conclusions about the annual and seasonal ozone hole as well as overall ozone concentration changes over Antarctica. Students use authentic data collected at the
This data plotting lesson is about temperature changes throughout the atmosphere. The data was collected together with the ozone data in January 2008.
The temperature vs. altitude profile allows students to make conclusions about annual and seasonal temperature changes in the atmosphere up to about 35 kilometers in the stratosphere. The best part of this lesson is using
