For years, I have used the Disney movie "Newsies" to teach the Progressive era of U.S. History. It has great examples of child labor, labor unions, the rise of big businesses, and labor reforms, and is a spectacular tool that is very engaging to students! (Consequently, it's also a Tony-award winning show on Broadway!) I created a Viewing Guide that is posted on TPT and is a best-seller (http://www.teacherspayteachers.com/Product/Newsies-Viewing-Guide). This year, I am not being allowed to use the full-length version in my classroom due to school policy. :-( So I created a PowerPoint and guide to using certain clips of the movie to teach about labor unions! Included in this PowerPoint is background information about the need for labor reforms, what a labor union is, what a strike is, and the background information necessary to use clips of Newsies to teach these concepts. It includes information about Pulitzer and Hearst's newspaper wars and their ploy to "guage" the newsboys. There are also several links and other suggested items that would be helpful in teaching these concepts in your classroom!
*For some reason, the PowerPoint didn't seem to transfer to TPT exactly how I had it created; the background slide is supposed to be very faded, so now the colors of the text look strange. All you have to do when you download this is click on the 1st slide, edit the background design and bring the transparency fader down, and apply to all slides. I don't know why it did that! :-)
