There is an exhibition now to the 11 July at the National Library in Paris, "Qumrân. Le secret des manuscrits de la mer Morte."
There is some pedagogical material with nice images in French here (background to the Qumran site) and here (about the textual history of the Bible, esp. the Hebrew Bible and LXX), and here (about the role of the Qumran community in the 1st century C.E.). And here is a quiz especially for young visitors with answers on the last page.
