Fourth of July celebration. Museum of History and Technology, 14th Street and Constitution Avenue NW. Through July 4, noon to 8:30 p.m. Free. 737-8811 or 381-6264.

History repeats itself this week as the Smithsonian's Museum of History and Technology commemorates Independence Day with a marathon celebration of music, dance, crafts and amusements reminiscent of the many ways this national holidy has been recognized over the past 202 years. The Fourth of July wouldn't be traditional without patriotic oratory, so there will be actors reciting well-known speeches of the past. Flag-waving will take on a new dimension as flagmakers practice their craft just in view of the flag that inspired our national anthem. Throughout the museum, other craftsmen, including a Colonial shoemaker, a lead-soldier caster and a drum maker will show their handiwork, and roving musicians will perform the music that has stirred so many hearts to patriotic fervor over the years. Outdoor concerts, from gospel to bluegrass, are scheduled daily, and the tradition of public dancing will be kept alive during evening dance demonstrations where crowd participation will be encouraged. Youngsters will delight in their own brand of festivities - jugglers, puppet shows, paper-boat making lessons, an organ grinder and other surprises.
