1. Sept. 3-March 12: “Train Time,” Rangos Giant Cinema

The American premiere of a movie opening in the Rangos Giant Cinema at the Carnegie Science Center visits the surprising intricacies of the modern railroad. “Train Time” mesmerizes with freight trains whisking through breathtaking landscapes. But the behind-the-scenes aspect of STEM careers available throughout the railroad industry is fascinating. Railroads continue to be an integral part of American life and “Train Time” provides an eye-opening glimpse into the roles of dispatchers, roadmasters, engineers and conductors. Catch a daily screening on the big screen. The $7 tickets are separate from Science Center admission.

2. Sept. 3 and 4: End of Summer Block Party, Children’s Museum campus

5. Sept. 9-Oct. 16: RADical Days, Allegheny County locations

It’s the most wonderful time of the year — in Allegheny County, at least.

Families can enjoy admission to local museums, hands-on creative activities, plus concerts and theatrical performances. Browse through the complete lineup and mark your calendar for a fun-filled month of free, free, free!

Event planners at the Pittsburgh Zoo & PPG Aquarium created a special intergenerational celebration for kids and their grandparents. On Grandparents Day, all pap paps and grandmas accompanied by a grandchild receive free admission. As a reminder that sharing is caring in the world of extended families, the grandkids are allowed several grandparents on the same deal. UPMC for Life members also receive free admission, with or without a grandchild in tow.

7. Sept. 17, 20, 23 and 25: “Rusalka,” Pittsburgh Opera

Once upon a time, long, long ago, before Disney reinvented Hans Christian Andersen’s “The Little Mermaid,” a Czech fairytale recounted the fanciful story of a water sprite named Rusalka. Rusalka falls in love with a handsome prince and asks a witch to transform her into a woman in exchange for her voice. Will love triumph or will dire consequences unfold? Follow the drama at Pittsburgh Opera’s production of “Rusalka,” opening the company’s 2022-23 season. “Rusalka,” which premiered in 1901, includes supertitle translations. The performance is best for romantically minded tweens, teens and adults. Tickets for ages 6-18 are half-price for all Pittsburgh Opera performances.

8. Sept. 18: Gemini Children’s Theater Fairytale Festival, Riverview Park

Gemini Theater — and its many fans — are thrilled to return to its annual fundraiser with an outdoor Fairytale Festival instead of its traditional Royal Ball. Celebrating 25 years of interactive children’s programming, revelers are invited to dress in their favorite fantasy attire as a royal, pixie or another character. The family-focused party includes a unicorn, royal petting zoo, carnival games and crafting. Expect tasty eats and an opportunity to dance, dance, dance. In addition to sponsorships, tickets are $5 for littles 2.5 or younger, and $35 for all others, with a special rate of $125 for a family of four.

10. Sept. 24: Junior Great Race, Point State Park

The day before the Richard S. Caliguiri City of Pittsburgh Great Race winds its way from Frick Park to The Point, kids have the chance to compete in the Junior Great Race. Runners ages 5-12 can participate in the 1-mile Family Fun Run with their grownups. The under-4 crowd is invited to the Tot Trot, where they’ll take off down a 50-yard walled chute to the finish line. Little ones who aren’t quite upright have their chance to race on their hands and knees in the Diaper Dash. All participants receive a commemorative medal upon completion of their race. Registration is $10 for the Junior Great Race. The experience is priceless.
