Today's building codes state spaces using furnaces have to have opportinity for creating combustion air because it used. Newer homes have ducting installed, during construction, which brings outdoors externally with an area nearby the furnace. This ducting, usually called make-up air duct, or combustion make-up air, is sized in accordance with the capacity from the furnace. Creative photo art projects around the Ugly Duckling, a children's book, can open students' eyes to seeing life within an entirely new way. In this lesson, students will photograph old, rusty, discarded and unusually placed items found everywhere. Using photo enhancing software, they're going to then develop a picture that can take what others may have seen as ugly, turning it into something beautiful. (Note: If the school doesn't have photo enhancing software, then Gimp, the industry free download, works extremely well.)
