Unesco's World Teachers Day is to be marked this year in Dublin on October 5th. an ommission omission which Paula Sweeney, Education Officer for Sheridan IMAX, says: "In conjunction with Chief O'Neill's CEOL, in Smithfield, we'll be hosting an evening for teachers and educators. It all starts with a reception in the Sheridan IMAX in Parnell Centre at 6 p.m. after which there will be a showing of Blue Planet, filmed from the Nassau Space Shuttle, which shows both the good and bad enviromental impact man has had on the earth. After that there's a tour of CEOL's interactive gallery of Irish traditional music and dance and another reception. All of it is of course free".
