ONE CROWN HEIGHTS NEIGHBORHOOD FESTIVAL at Brower Park (Sept. 15, 1-6 p.m.). A Brooklyn community with a long history, Crown Heights is known for its diversity — and occasionally for its divisiveness. Sponsored by the Brooklyn Children’s Museum and other organizations, this free annual festival seeks to unify the neighborhood by embracing its multiple heritages. This year’s celebration will feature Caribbean cultural performances by Tropical Fete, double Dutch by the group Ms. K’s Swagga Jumpers, Jewish-themed tunes from Uncle Moishy and spirited moves from Victory Music and Dance Company. It will also include fire safety demonstrations, health screenings, a mobile recreation van, a Brooklyn Public Library Bookmobile and kosher and nonkosher food. The festivities are rain or shine, but you can always duck inside the museum: It will offer free admission all day.

RAPTOR FEST at the East Meadow, Central Park (Sept. 14, noon-3 p.m.). Expect an air show at this event, but the performers overhead won’t be creative pilots. These soaring stars are raptors, or birds of prey, the guests of honor at this free annual celebration. Presented by the Urban Park Rangers, the program will feature a master falconer and species including the screech owl, the red-tailed hawk, the kestrel and the bald eagle, as well as some not native to the Northeast, like the Harris hawk, the black vulture, the Eurasian eagle and the spectacled owl. Families will be able not only to see these varieties up close, but also to learn about raptor traits and behaviors at activity stations where children can compare their own grasping strength to that of birds of prey and the length of their outstretched arms to avian wingspans. To be held rain or shine (except for thunderstorms), the festival will also encourage flights of fancy: Wearable props will help young visitors transform themselves into winged hunters.

SATURDAY SCHOOL at Rockefeller Plaza (Sept. 14, 11 a.m.-3 p.m.). Don’t let the title intimidate your kids: This free event promises no homework and plenty of fun. Devoted to entertaining explorations of STEAM (science, technology, engineering, the arts and math), this fair will host programs like CodeScty, which uses rap music and hip-hop videos to teach computer science; KidCoolThereminSchool, dedicated to hearing, playing and learning about that instrument; and Art Sundae, in which the author and artist Christopher Myers will engage children in drawing a “map” on the plaza that incorporates outlines of their bodies. Other highlights of the festival, taking place rain or shine, include fire safety demonstrations, hands-on activities from the Climate Museum, concerts by Rock and Roll Playhouse and the debut of MICRO’s Perpetual Motion Museum, a physics display that’s the size of a vending machine.
