A Ribbet-ing Frog Show in San Francisco

San Francisco’s Marina District is being invaded by frogs, thanks to an exhibit at the Exploratorium.

“Frogs,” running next Saturday through Sept. 12, will have tubfuls of live frogs, toads and tadpoles, plus more than 20 educational exhibits. You can compare your heartbeat to a frog’s, check out its innards through computer simulation and match your attempt at a frog call against the real thing (monitored by a voice-spectrum gizmo). Other sections investigate the worldwide epidemic of malformed frogs and declining populations, and, on a lighter note, arts, artifacts and kitsch celebrating the hopping amphibians.

Among special events are “Eat Your Own Frog Food,” March 27 and 28, with an allegedly edible menu of insects, bugs and worms; and a lesson on building a frog pond, March 13 and 14.

Entrance to the museum, at the Palace of Fine Arts, 3601 Lyon St., is $9 adults, $5 ages 6-17, $2.50 ages 2-5. Information: tel. (415) 561-0360.
