Marian Koshland Science Museum of the National Academy of the Sciences
This virtual museum website provides easily understood scientific information that helps both policy makers and the public answer important questions about the changing global climate in order to promote informed decisions. The site examines the Earth's natural carbon balance and the ways that humans are affecting this balance, then goes on to explore possible responses to global warming both at a personal and national level. It explains some of the methods for measuring past change and modeling future changes, as well as discussing the impacts of and responses to global warming. There are several teaching activities listed as "pre- and post-visit," though they may also be used as stand-alone exercises, and four more teaching activities in the 'Responses to Change' section of the site, including a carbon dioxide calculator that examines personal and national actions that could be taken to reduce carbon dioxide emissions.
