I have a lot of respect for teachers and homeschoolers. Teaching is a tough job that is even made tougher due to the budget constraints that almost all teachers face. That is why I love finding free and useful resources for teachers.

The USEPA has an educational goal as part of its mission and they offer a wide selection of free education materials for teachers. These include posters, CD-ROMs, activity books, lesson plans and much more. Read the offer profile for the details.
