Most of the events that take place at the Annenberg Center are decidedly grown-up—except between May 1 through 7. That's when the renowned Children's Festival—now in its 21st year—comes to town, featuring a variety of kids' and family performers. This year's schedule includes the Fred Garbo Inflatable Theater Co., where big blow-up shapes dance, slither and bounce; Gale LaJoye's performance, "Snowflake," in which he plays a loveable homeless character; and musician Dan Zanes (left), former member of the Del Fuegos who plays hip, rockin' kids' music.

A host of free performances sponsored by WXPN's show, "Kids Corner," will also take place on the plaza in front of the Annenberg Center, and offer something for every child's taste—from The Science Show to Penn's own Stimulus Children's Theater. Let's play! .

—THE CHILDREN'S FESTIVAL runs from May 1 through 7 at the Annenberg Center, 3680 Walnut St. Tickets: $10 for children ($7 each additional ticket); $12 for adults ($9 each additional ticket). Tickets/info: 215-898-3900 or www.pennpresents.org
