At home we are the TV police, so it would be hypocritical to recommend watching a day of cartoons, right? Fooled you -- they're not on TV. Symphony Hall is your family room today from 10 a.m. to 4 p.m. for Classical Cartoon Festival, where kids watch cartoons animated to classical music scores. OK, there will be a few breaks in between "What's Opera Doc?" "Rabbit of Seville," "Knighty Knight Bugs," "Johann Mouse," "Mouse in Manhattan," and other 'toons. These breaks include the Boston Children's Chorus (2-2:30), BSO French horn player Daniel Katzen (11:30 to noon), all-day fun with an interactive percussion workshop, Symphony Hall tours, magic, theater, storytelling, treasure hunts, and Krispy Kreme you-know-whats (250 dozen of them). Tickets to 301 Mass. Ave. are $6; free under age 3. Call 888-266-1200.Wardrobe malfunctions for these female role models are probably (and thankfully) limited to lab coat stains and loose buttons. At today's "Women in Research Day" at the Museum of Science, more than 25 women from research laboratories in the Boston area give short presentations and talk with visitors one-on-one about the field of research. Included from 11 a.m. to 3 p.m. are Tweeny Kau and Liz Jarvo from Harvard University. Exhibit Hall admission is $13; $11 for seniors; $10 for ages 3-11. Call 617-723-2500.
Rather than change radio stations, change rooms. The Commander's Mansion in Watertown is like a living radio, with rooms hosting different music styles and events. "Channels" at today's "A Musical Extravaganza Open House: A Music Festival," from 1 to 4:30 p.m., include Out of the Ordinary, an a cappella group from Lexington High School; musicians from the Berklee College of Music; fiddler and step dancer Emerald Foreman; music of Armenian, Greek, Turkish, and Arabic cultures; Lindsay MacIndoe's acoustic music; musicians from the New England Conservatory of Music; and the Longy Saxophone Quartet. Free. At 440 Talcott Ave. (Donations support the development of the Arsenal Center for the Arts.) Call 617-923-0100.
Imagine strawberry fields where all you need is love. You insert the punctuation to get three of the songs perfomed at 8 p.m. by the five-piece band Working Class Hero. The concert "A Tribute to John Lennon" at the Somerville Theatre stars Tim Piper as John Lennon. Piper performed as Lennon at Tom Hanks's 10th wedding anniversary. Tickets to 55 Davis Sq. are $23.50, $26.50. Call 617-628-3390, 617-931-2000.
You enjoy the characters (mean queen, beautiful daughter, handsome hero, angels, bully, magic flute) and plot; let the kids deal with the themes (autonomy, self-determination, sexism, ideals of wisdom, power, beauty). New England Conservatory Opera Theater performs a fully staged production of Mozart's "The Magic Flute" today at 2 and 8 p.m. and tomorrow at 3 p.m. at the Cutler Majestic Theatre, 219 Tremont St. The student cast and orchestra is conducted by John Greer, new head of NEC's opera studies department. Tickets are $15; $12 for students, seniors. Call 617-585-1260.
If you missed Mardi Gras this year because you were busy making PB&J sandwiches and driving to hockey games, plan an outing to the Big Apple Circus. "Carnevale!" opens today and entertains with masquerade balls, puppets, parades, confetti, floats, samba, jazz, zydeco, and more through May 9. This weekend's shows at the Bayside Expo Center, 200 Mount Vernon St., Columbia Point, are at 12:30 and 4:30 p.m. Tickets are $13-$52. Call 617-931-2787.
Lulu knew about rose-colored glasses. Gretchan A. Pyne wrote "Lulu's Rose Colored Glasses" the spring before her daughter Olivia "Lulu" Pyne died at age 4. The book is a story of hope: "Lulu, everything is so beautiful and rosy!"
