				A joint paper produced by the American Enterprise Institute and the Brookings Institute titled&nbsp;<a href="http://participatoryscience.org/sites/default/files/mercury in the environment.pdf"><strong><span style="margin: 0px; padding: 0px; border-width: 0px; outline-width: 0px; font-size: 13px; vertical-align: baseline; background-color: transparent; line-height: inherit; color: rgb(78, 125, 191); text-decoration: none;">Mercury in the Environment: A Volatile Problem</span></strong></a><a href="http://www.moodle.org/0.0933768476010669" rel="nofollow" style="margin: 0px; padding: 0px; border-width: 0px; outline-width: 0px; font-size: 13px; vertical-align: baseline; background-color: transparent; line-height: inherit; color: rgb(78, 125, 191); text-decoration: none;">&nbsp;</a>provides an excellent, readable survey of the entire issue. The Biodiversity Research Institute has also published an excellent overview -- this one more focused on the Northeastern US -- titled&nbsp;<a href="http://www.briloon.org/old_site/mercury/BRIMercury.pdf"><strong><span style="margin: 0px; padding: 0px; border-width: 0px; outline-width: 0px; font-size: 13px; vertical-align: baseline; background-color: transparent; line-height: inherit; color: rgb(85, 26, 139); text-decoration: none;">Mercury Connections</span></strong></a>. You might want to consider printing off a number of copies of these two documents for use by the students in the class.&nbsp;</p>

				An interesting lesson plan comparing the <strong><a href="http://cehp.niehs.nih.gov/static/pdf/scied/2007/carbon.pdf">carbon cycle to the mercury cycle</a></strong> has been created for the National Institute of Environmental Health Science. Scaffolding the mercury cycle to the carbon cycle may help your students understand the mercury cycle better.</p>

				Below is a link to additional mercury related activities for both high school and middle school levels. They are on the Environmental Protection website. The activities were adapted from &ldquo;Mercury in Schools and the Community: A National Issue&rdquo; from the University of Wisconsin System Board of Regents, March 2002. Even though it is in the middle school activity section, the Toxic Treasure Hunt would be a good way to show where mercury can be found in the home and the school. Look for the heading &ldquo;Student Information and Activities&rdquo; The activities are listed by grade level:&nbsp;<strong><a href="http://www.epa.gov/region7/mercury/educator_toolkit.htm" rel="nofollow" style="color: rgb(78, 125, 191);">http://www.epa.gov/region7/mercury/educator_toolkit.htm</a></strong></p>

				<strong><a href="http://www.epa.gov/ttn/oarpg/t3/reports/volume4.pdf" rel="nofollow" style="color: rgb(78, 125, 191);">Volume 4 of the EPA&#39;s Report to Congress on Mercury</a></strong>&nbsp;is an incredibly valuable resource for all the material in this module, whether you are working with fish, human hair, or other kinds of samples. It is a big document, but well worth downloading and using as reference.&nbsp;</p>

				You will also find value in the other volumes in the EPA&#39;s report to Congress. There is a&nbsp;<strong><a href="http://www.epa.gov/mercury/eco.htm" rel="nofollow" style="color: rgb(78, 125, 191);">website that provides access to the entire report</a></strong>, along with other good information.&nbsp;</p>

				The EPA also has a good, brief&nbsp;<strong><a href="http://www.epa.gov/waterscience/fish/advice/mercupd.pdf" rel="nofollow" style="color: rgb(78, 125, 191);">summary of mercury concentrations</a></strong>&nbsp;in different species of fish. This will be important whether you are looking at ecosystems in the field or at human hair.&nbsp;</p>

				The University of Wisconsin-Extension has produced&nbsp;<strong><a href="http://www.mercuryinschools.uwex.edu/curriculum/focus_on_hg.htm" rel="nofollow" style="color: rgb(78, 125, 191);">a nice introductory piece on mercury</a></strong>&nbsp;as well as a&nbsp;<strong><a href="http://www.mercuryinschools.uwex.edu/curriculum/national-curriculum.htm" rel="nofollow" style="color: rgb(78, 125, 191);">complete mercury curriculum</a></strong>. This mercury curriculum is substantially different from what we have here, but it definitely a useful resource and worth looking at. Speaking very generally, the primary difference is that the University of Wisconsin curriculum is more focused on knowledge about mercury as a learning objective, while we are more focused on mercury as a means to learning objectives related to systems, change, and the nature of science.</p>
