Technology miniMOOC: Museums for Technology teaching

There are some photographs.

Use a web 2 tool to create a timeline. Order the photographs in front of you chronologically based on logical reasonings.(What makes you believe this photo is the oldest, is it its theme, its technique ..etc? Can you make a guess about the period when it was taken? ) and show them on the timeline.

Let’s talk about historical, geographical, political and technological backgrounds of the photos please.
