The following activities were designed to facilitate as well as enhance teacher instruction on a variety of topics under the larger heading of "Greenhouse Gases and Earth's Changing Climate." Topics range from the simplistic to the more complex- from Dr. Seuss' "The Lorax" to computation activities focusing on the formation of CFCs and the Rule of Ninety. Each group of activities is preceded by a Teacher Background section intended to provide a thorough yet condensed version of the science incorporated within the teaching activity. It is assumed that the teacher has at least a general knowledge of scientific terminology and processes within the disciplines of Earth and Physical science.
The intended audience ranges from elementary to high school science. Their instructional use and application is left entirely to the discretion of the classroom teacher. Activities are intended to be modified to meet the variety of learning styles and ability levels present in a typical classroom. Teachers are encouraged to adapt them as they see fit.
Each module is tied to one of the 50 climgraphs available on the NOAA ESRL/Global Systems Division website. The transparencies which can be made from these illustrations are meant to serve as a visual tool for presenting the basic concept being taught. Transparencies can be used alone or in conjunction with others, in sequence or out and should be selected to coincide with the ability, interest and cognitive level of the students.
All of the materials in the "Greenhouse Gases and Earth's Changing Climate" curriculum were prepared by a science education specialist in collaboration with scientists and technicians at the National Oceanic and Atmospheric Administration David Skaggs Research Center in Boulder, CO.
