The National Society of Professional Engineers and National Engineers Week created “A Sightseer’s Guide to Engineering” to help students understand how engineering affects their lives. (The 50th anniversary of National Engineers Week was celebrated Feb. 18 to 24, 2001, and was marked by the creation of this site.) This “unique travel guide that highlights engineering achievements across the country” offers users a bright, colorful, easy-to-use interface, complete with photos of engineering marvels across the nation and interesting factoids about why these landmarks are significant. Users can click on a state to find a list of landmarks therein, usually about four or five per state. The site discusses points of interest ranging from amusement parks and buildings, to bridges to dams, to highways, power plants, and mass transit systems. Principles related to a number of engineering disciplines are explained, including aerospace, computer, chemical, electrical, industrial, mining, and nuclear engineering. Kids and teachers can learn more about the Hoover Dam’s 4,360,000 cubic yards of concrete and the building of the presidential monument at Mt. Rushmore. The site is full of interesting trivia. For instance, did you know that the 110-story towers One and Two of the World Trade Center are 1,368 and 1,362 feet tall, respectively? This is a great source for fun and enlightening facts.
