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.
Creaza offers you an integrated, web-based toolbox for creative work, both at school and in your free time. You use the toolbox along with various fully developed thematic universes: historical periods, fairy-tales, fantasy worlds, and current challenges, such as climate/environment.
