The document discusses teaching Spanish or American culture as part of a second language class. It recommends integrating web 2.0 materials, such as photos from a trip to Spain that show historical sites from the Roman era like arenas, aqueducts, and theaters in Mérida, España. The aqueducts carried water from distant rivers into cities, with some sections supported by arches that have been partially destroyed over time. A video also shows how long the Roman aqueducts could be.
