You cite the lessons original source, and do not white-out the copyright footer on the pdf files 3. Do not copy and paste lessons onto your website. A link to the original is to be used. 4. Do not claim these lessons as your own work. NOTE: This disclaimer is modeled after a couple of my favorite websites: The Science Spot and Middle School Science. Thanks, teachers!
