Watch Bill Nye the Science Guy Season 5 Episode 4 Online

Towers, teepees, castles, and condominiums – some kind of planning goes into all buildings, no matter how big or small. Architects are people who design buildings, and the areas around buildings. Usually architects draw on a computer or a big desk (a drawing board). The plans show the dimensions of all parts of a building. Architects try to design with the purpose of the building in mind, but even buildings used for the same thing can look very different.
