Skyscrapers evolved from the inside out — as steel frames became stronger, windows and walls became lighter, like a "skin." Students can construct high-rise buildings (or low-rise designs) that are extremely light and open — they're made with paper straws and corrugated plastic joints (no glue required). Imagination grows with the construction — higher and higher! For a pdf version and a materials list of this lesson, follow this link http://www.dickblick.com/lesson-plans...
