If you have to teach about the creation of polders in the Netherlands, look no further because this is the lesson for you. It incorporates an article for reading about polders, pictures of polders, suggestions for how to view polders on Google Earth, links to the best YouTube videos about polders and other ways the Dutch interact with their environment, and even suggested short answer questions that your students can answer about polders. The lesson includes lots of potential discussion for you and your students. Most slides come with teaching tips in the notes section. If you do not have access to Google Earth, I have provided many screenshots that will still allow your students to view polders from satellite images. I think this is a really great lesson on how people in the Netherlands have reclaimed land from the sea. Check it out.
