PBS Teachers is a wonderful site with lots of resources and supplemental material for teachers to use with students. This particular link will take you directly to the STEM education resource center: Professional Development and the focus on this page is Global Climate Change Modules from PBS and NASA. However, if you look at the top of the page you can choose a specific grade band and then within that there are various content areas that can be chosen. Looks like a very interesting site with lots of resources to select from.
