This is a PPT presentation I use to introduce students to the issues involved with returning antiquities to the countries of origin. I then divide the class into smaller sections for a debate, assigning each side to argue for or against returning the items. (You can have small debates about each item or one larger one addressing the issues in general.) I based the lesson on this blogpost: https://mic.com/articles/76321/9-priceless-artifacts-museums-should-return-to-their-home-countries#.9vac2PqFE. You would want to use more rigorous articles for background information. Each PPT has an image of the item plus the talking points in the notes. You can enhance with an internet research project for each item.
