What it is
The Arizona Science Center is a 120,000-square-foot hands-on science museum at Washington and Seventh streets in downtown Phoenix, in a building Antoine Predock finished in 1997 and the institution has been adding to since. Inside are four levels of galleries, a five-story giant-screen theater, the CREATE makerspace, and the Dorrance DOME, the planetarium that closed for a rebuild in spring 2024 and reopened on October 18, 2025 as an 8K LED dome with 194 seats that the center calls the most advanced planetarium in the Southwest.
The galleries cover what a science center covers, the human body, forces and motion, flight, weather and the desert, and they are designed to be touched. The Forces of Nature gallery on the upper level, with its simulated storms, is the one children talk about in the car. The building sits beside Heritage Square, the block of Victorian houses that is the oldest piece of downtown Phoenix, so a visit ends naturally with lunch there.
Why leave Scottsdale for it
Scottsdale has no science museum and the Valley has only this one. Our Scottsdale with kids note is honest that the city’s own indoor options for children thin out after the Children’s Museum of Phoenix age; this is where the eight-to-fourteen bracket goes on the day the pool is rained out or the thermometer passes 110. The DOME is the other reason: a Scottsdale visitor who has read our stargazing note and wants the explanation before the drive to the dark sky will get it here.
The practical version
Twenty-five minutes from Old Town via Loop 202 and Seventh Street. Park in the Heritage and Science Park garage at Fifth and Monroe and validate at the desk. Hours are short, roughly 10:30 AM to 4 PM, Tuesday through Sunday, so arrive at opening. Buy general admission plus one DOME show; the giant-screen film is optional. Three hours covers it with children.
When to go
Weekday mornings in the school year bring field trips, which arrive around ten and leave around one; a weekday afternoon in the school year is the quietest the galleries get. Weekends are busy from opening. Summer is the center’s season, when every family in the Valley has the same idea on a Saturday, so come at 10:30 on the dot or wait until after two.
Check the calendar before you go: the center closes occasionally for private events, and the DOME runs after-hours shows and adult nights that use the building differently.
What to do, in order
- The Dorrance DOME. Book the first show after opening. The daytime program is astronomy and science films at 8K on an LED dome rather than a projector; it is noticeably sharper than any planetarium you have sat in.
- The upper galleries. Forces of Nature, then the body and physics floors on the way down, which is how the building wants to be walked.
- CREATE. The makerspace, an 18,000-square-foot addition, runs drop-in projects; check what is on the board.
- The giant-screen theater. Five stories tall. Worth it if the film is good; skip it if the children are fading.
With kids
The sweet spot is five to fourteen. Younger children do better next door at the Children’s Museum, which is a two-block walk east on Washington, and a day that combines the two is a long one. Strollers are fine throughout. The terrace off the upper level is the shaded place to eat a packed lunch; otherwise walk into Heritage Square.
Heritage Square
The museum backs onto the oldest block in Phoenix: the 1895 Rosson House, the Victorian cottages and, in the 1929 Baird Machine Shop, Pizzeria Bianco. The noon line at Bianco is the short one.
The story
The Junior League of Phoenix proposed a science center for downtown in 1980, when downtown Phoenix was a place people left at five. The nonprofit incorporated in 1982 and opened in 1984 as the Arizona Museum of Science & Technology, in 10,000 square feet of storefront on the garage level of the downtown Hyatt, which is about as unpromising a start as a museum can have. It worked well enough that the city and the state put up a building.
Antoine Predock, the Albuquerque architect whose work treats the desert floor as the first material, designed the 120,000-square-foot center that opened in 1997 at the east end of Heritage Square, which was renamed Heritage and Science Park for the occasion. The building is a set of concrete wedges and a glass slot, with the giant-screen theater as the tall block; it is one of the few pieces of downtown Phoenix architecture from the decade that an architect would drive to see. A 2011 addition by Architekton moved the entrance to Washington Street. CREATE added the makerspace. The planetarium, the Dorrance, closed in spring 2024 for a rebuild and reopened on October 18, 2025 as the Dorrance DOME, an 8K LED dome seating 194, the start of what the center describes as a five-year renewal of the whole building.
The Scottsdale connection
The city’s museum shelf, which our museums note ranks honestly, is art, Western history and one contemporary-art building; science is the gap, and this is where it is filled. The Desert Botanical Garden, ten minutes from Old Town, is the other half of a Phoenix science day: the garden for the living desert, the center for the physics and the sky.
Getting there
Loop 202 west from Scottsdale to the Seventh Street exit, south to Washington Street, west two blocks; about twenty-five minutes with no traffic. Park in the Heritage and Science Park garage at Fifth Street and Monroe and have the ticket validated at admissions. Rideshare drop-off is on Fifth Street by the entrance. Light rail stops at Third Street and Washington, which helps from a downtown hotel but not from Scottsdale, which has no rail; the getting around note covers that trade-off.
