Orchestra of the Future

Young musicians began an intensive three weeks of musicianship and professional development at the University of Maryland this week. The public can glimpse the fledgling talent in three performances led by internationally renowned conductors. In the first of three consecutive Saturday performances, conductor Michael Stern and the students participating in the National Orchestral Institute will play Austrian composer Anton Webern's "Im Sommerwind." Leonard Slatkin directs the group on June 19, and JoAnn Falletta conducts on June 26. Tickets are $20 or $5 for students, and performances begin at 8 p.m. in the Dekelboum Concert Hall of the Clarice Smith Performing Arts Center, Stadium Drive and University Boulevard, in College Park. 301-305-2787.

Roman Days

Ancient Rome comes to life during the "Roman Days" army encampment at Marietta House Museum. Part festival, part historical reenactment, the annual event features reenactors playing legionnaires and gladiators to demonstrate armor, battle tactics and camp life. From 10 a.m. to 4 p.m. on Saturday and Sunday, there will also be craft demonstrations, educational activities and food vendors at the museum at 5626 Bell Station Rd., Glenn Dale. Admission is $4 for adults, $2 for ages 4-18 and free for ages 3 and younger. 301-464-5291.

Fishing Fun

Kids can get out their rods and learn how sport-fishing is done at Kids' Fishing Day on Sunday. Despite the event name, all ages can watch fishing demonstrations, take a tram tour to learn about wildlife conservation and participate in nature activities. Children can also try out their catch and release skills from 1 to 4 p.m. Sponsored by the U.S. Fish and Wildlife Service, the program is free and takes place at the Patuxent Research Refuge, National Wildlife Visitor Center, Powder Mill Road, between the Baltimore-Washington Parkway and Route 197, Laurel. 301-497-5887.
