The impressive Star-Spangled Banner, America's almost 200-year old, 34-by-34-foot flag that inspired Francis Scott Key to pen the national anthem, is a highlight exhibit at the Smithsonian Museum of American History.

But as important as the flag and the anthem are to our national identity, it's no secret that singing the anthem is not for the faint-of-voice or for the monotone, although it's publicly sung in every imaginable venue by choirs, opera singers, pop and rap performers, and many, many, many more. Now, the Smithsonian offers visitors to the online Star-Spangled Banner exhibit a chance to show the world how it ought to be sung on YouTube.

But first, tour other elements of this online exhibit. The Star-Spangled Banner site looks at the flag as history, as artifact, and as symbol. It weaves narratives of the past with present-day meaning. The exhibit tells the story of the flag and invites viewers to explore the physical features and dimensions of this carefully-preserved remnant. Close-up zooms focus on the fabric, weave, and color and explain history and conservation efforts over the years.

Mini-essays and quizzes give context to the War of 1812 and explain why the Star-Spangled Banner and subsequent versions of the flag came to hold such meaning for Americans. Read the history of the American flag, and investigate rules and rituals surrounding its display and use.

The interactive feature, Share Your Story, encourages individuals to talk about the meaning of the flag in their own lives and to upload photographs illustrating that meaning.

Do you celebrate Flag Day? Though not an official federal holiday, June 14 (one week from today) memorializes the day when the Second Continental Congress approved the first version of what evolved into our modern national flag.

Since 1777, the flag has gained 37 stars and exact specifications for color and design, but it's always been recognizable. Red, white, and blue, it has waved over people, places, and events throughout U.S. history. How much do your students know about the flag and its history?
