Pick of the Pack

For children: Trader Center launch

Between ant farms and dinosaur models, nerdy children tend to develop an affinity for rocks. It starts with unpolished quartz, which turns up in driveways and playgrounds and out in the woods. Then it’s on to agates, a type of volcanic rock that is polished and rounded and often falsely labeled as onyx, and then cracked geodes, and finally — for the bold — uncracked geodes, which are a blast. He or she may learn to organize his or her collection based on whether a rock is igneous, sedimentary or metamorphic; or alphabetically, placing Nepheline syenite next to Nephelinite, Pegmatite by Peridotite. If this all sounds like it’ll make a dent in your wallet, it can, but it doesn’t have to. The National Children’s Museum is launching its Trader Center this weekend, where your child can bring the rocks he or she has discovered, and trade them for better rocks. They also can learn about bartering, which is another lesson that may very well save parents a fortune.

Saturday at the National Children’s Museum, 112 Waterfront St., Oxon Hill, Md.

Concerts: Smithsonian Folklife Festival

The big hook for this year’s Smithsonian Folklife Festival was George Clinton, funk’s great uncle. If you weren’t lucky enough to catch that show, which featured funk demigods Meshell Ndegeocello, Ivan Neville and Dumpstaphunk, don’t despair. Good shows worth seeing are still available at this year’s festival. On Friday, you can watch the Ebony Hillbillies, an all-black bluegrass group representing the sounds of the Virginia Piedmont. For more international flavors, there’s Imamyar Hasanov and Pezhham Akhavass, two Azerbaijani musicians, who will bring the sounds of the Caspian Sea to the District on Thursday.

Through July 7 on the National Mall between the Smithsonian Museums

Tour: History on Foot with James McDevitt

Modern policing — from equipment to tactics — essentially has made political assassination a thing of the past. In 1865, however, there were no crime-scene investigators, a la “CSI”; no wiretapping; no credit card or rental car records. Finding out who killed President Abraham Lincoln was incredibly complicated. Even tougher? Busting open the conspiracy behind the assassination. “Investigation: Detective McDevitt,” written by Richard Hellesen, is a 19th-century police procedural that attempts to retell the investigation of Lincoln’s murder to an audience used to having complicated crimes solved in 45 minutes or less. This mystery takes slightly longer to solve — roughly two hours — and involves getting up off the couch and walking roughly 1.4 miles.

Through October at Ford’s Theatre, 511 10th St. NW
