The Google Cultural Institute is one of those hidden gems from Google that needs to be shared. From their site, "Discover exhibits and collections from museums and archives all around the world. Explore cultural treasures in extraordinary detail, from hidden gems to masterpieces."
Recently the site has offered 3d scans of objects found at some of the museums. For example a scan of Emperor Augustus. https://www.google.com/culturalinstitute/asset-viewer/emperor-augustus/LQGccT1lCiVWgA
Just remember this when using the site with students. This is art. Some art should be looked at with older and/or more mature students.
Take a look around and take your students to places they may never get to visit.
