This was a project wherein students took a chemical from the CDC Third Report on chemical exposure and studied the chemical, why we use it, what are it's effects, etc...  Then many students created a Public Service Announcement alerting the public to harm they may be facing.  This was very interesting because some of the students were looking at phthalates and bisphenol-A before there was a huge public outcry this past Spring.  They liked the fact that something they were studying and knew about then later became big news.

 Some of the more exemplary projects include one on PAH's, Mercury, Formaldehyde, Cobalt, and Cadmium but you can see all of them here and here.

Attached are the UbD, Student Guide, and Rubric.
