Children's museum East of Scottsdale Mesa Since the late 1970s

i.d.e.a. Museum: Mesa's Children's Art Museum in a 1950s Grocery Store

The i.d.e.a. Museum (imagination, design, experience, art) is the City of Mesa's children's museum, founded at the end of the 1970s as the Arizona Museum for Youth and renamed in 2014. It fills a refurbished 1950s grocery store on Pepper Place in downtown Mesa with about 20,000 square feet of hands-on art and design exhibits: a permanent play gallery called the HUB, a rotating themed exhibition, and studio tables where children make things to take home. It is twenty-eight minutes from Old Town, two blocks from the Mesa Arts Center and the light rail, and best for children under about eight.

The 30-second version

  • Founded in the late 1970s as the Arizona Museum for Youth, the first children's museum in the country devoted to fine art; renamed i.d.e.a. (imagination, design, experience, art) in February 2014.
  • Housed in a converted 1950s supermarket with roughly 20,000 square feet of exhibition space, owned and run by the City of Mesa.
  • Two parts: the HUB, a permanent gallery of open-ended building and play areas, and a themed exhibition that changes a few times a year (currently one about absurd and whimsical art), both with studio tables for making.
  • Open Tuesday through Saturday from 9 AM and Sunday afternoons, closed Mondays; admission is a flat per-person price, free under age one, and a visit runs ninety minutes to two hours.
  • Twenty-eight minutes from Old Town; pair it with the Arizona Museum of Natural History two blocks away and a sandwich on Main Street for a full downtown Mesa day with small children.

Why leave Scottsdale for it

A city-run children's museum built around making art rather than pressing buttons, in a converted 1950s supermarket two blocks from the Mesa Arts Center; the calm, under-eight half of a downtown Mesa museum day, and a good answer to a hot afternoon.

What it is

The i.d.e.a. Museum is Mesa’s children’s museum, run by the city, in a converted 1950s supermarket on Pepper Place, two blocks north of Main Street and the Mesa Arts Center. The acronym stands for imagination, design, experience and art, which is the museum’s whole program: it began at the end of the 1970s as the Arizona Museum for Youth, the first children’s museum in the country devoted to fine art, and when it rebuilt itself in 2014 it kept the art and added design and making. About 20,000 square feet of exhibition space is split between the HUB, a permanent gallery of open-ended play and building areas for the youngest children, and a themed exhibition that changes a few times a year, with staffed studio tables where children paint, sculpt and construct things to carry home.

It is not a science center and it does not try to be one. There are no rocket simulators and very few screens. The exhibits are tactile, slow and built for the under-eights, and the museum is small enough that a parent can sit down.

Why leave Scottsdale for it

Because Scottsdale has no children’s museum (our kids note works around that with parks and the Railroad Park), and because the two Mesa museums together make a day. This is the gentle half, for the toddler and the kindergartener, and the Arizona Museum of Natural History two blocks east is the loud half, with the dinosaurs for their older sibling. In July and August, when the summer playbook says to be indoors from eleven to four, this is one of the places to be.

The practical version

Twenty-eight minutes from Old Town via the 101, the 202 and Country Club Drive, with its own parking lot. Open from 9 AM Tuesday through Saturday and Sunday afternoons, closed Mondays. Admission is a flat per-person price, free under one. Ninety minutes to two hours. Main Street’s lunch places are a two-block walk.

When to go

9 AM on a weekday is the hour that makes this museum worth the drive: the doors open, the HUB is empty, and your two-year-old has the building to themselves until the preschool groups arrive. Weekend afternoons are busy and fine. Summer is the peak season for the obvious reason, and the museum’s air conditioning does the work the desert cannot. The themed exhibition changes a few times a year, so a return visit in a different season is a different museum.

What to do

Start in the HUB, the permanent gallery, which is built around open-ended materials: blocks, ramps, light tables, a stage, things to stack and sort. Then the themed exhibition, which at this writing is about absurd and whimsical art, with children cast as art detectives and asked to invent creatures. The studio tables are the point of the whole museum: real paint, real clay, a staff member who knows how to talk to a four-year-old about color, and a project to take home. Budget half your visit for them and dress accordingly.

The neighborhood

Pepper Place is two blocks from Main Street. Worth Takeaway does the sandwiches; the Mesa Arts Center plazas, with their shade and water channel, are the place to eat them. The light rail’s Center/Main station is a short walk, and for a child who has never ridden a train, one stop to Mesa Drive and back is a free attraction.

The story

In 1978 a group in Mesa chartered a nonprofit called the Arizona Museum for Youth with an idea nobody else in the country had tried: a children’s museum devoted to fine art, where the galleries hung real paintings at a child’s eye level and the programs taught children to look and to make. It opened to the public around 1980 and settled, eventually, into a 1950s grocery store on Pepper Place that the city refurbished into roughly 20,000 square feet of galleries. For three decades it ran as a hybrid, half art museum for children and half studio school, under the City of Mesa.

By the 2010s the children’s-museum field had moved toward hands-on everything, and the museum rebuilt itself to meet it without abandoning the art. On February 6, 2014, it reopened as the i.d.e.a. Museum, with the HUB as a permanent play gallery, a rotating themed exhibition and the studio program at the center. A year later the light rail arrived two blocks away, and the museum found itself part of a downtown that the Mesa Arts Center, the natural history museum and the restaurants on Main were turning into the East Valley’s best small-city core.

The Scottsdale connection

Scottsdale’s museums, as the museums note lays out, are grown-up ones: Western art, contemporary art, Frank Lloyd Wright. SMoCA runs good family days, and the Railroad Park is the city’s great toddler attraction, but a Scottsdale family with a four-year-old and a free hot afternoon has always had to leave town, and Mesa’s museum is the closest place built for exactly that child.

Getting there

The 101 south to the 202 east, exit Country Club Drive, south to Main Street, east to Robson Street, north two blocks to Pepper Place; the museum and its lot are on the left. Twenty-eight minutes from Old Town, thirty-five from the Camelback corridor. From Tempe, the Center/Main light-rail station is three blocks; our getting around note covers why the rail is a Tempe option and not a Scottsdale one.

The pages this one leans on: the area, the note, and the places inside Scottsdale it pairs with.

The third-largest city in Arizona and the one visitors overlook: two spring-training ballparks, the Valley’s best performing-arts center, a dinosaur museum, a warbird museum, and a downtown that the light rail reaches.

Questions people actually ask

How far is the i.d.e.a. Museum from Scottsdale?

About twenty-eight minutes from Old Town with no traffic: the 101 south to the 202 east, exit Country Club Drive south to Main Street, east to Robson, north two blocks to Pepper Place. Parking is in the museum's own lot. From Tempe, the Center/Main light-rail station is a short walk.

What ages is the i.d.e.a. Museum for?

Toddlers to about eight or nine. The HUB works for a two-year-old and the studio projects are pitched at early elementary. Older children will do better at the Arizona Museum of Natural History two blocks away, which is why the two are usually combined.

How long does a visit take?

Ninety minutes to two hours, depending on how long your child stays at the studio tables. The building is single-level and stroller-friendly.

Is the i.d.e.a. Museum the same as the Arizona Museum for Youth?

Yes. It opened at the end of the 1970s as the Arizona Museum for Youth and took the i.d.e.a. name in 2014, when the exhibits were rebuilt around design and making as well as fine art.

Is there anything comparable in Scottsdale?

Not really. SMoCA runs family programs and the Railroad Park is the toddler attraction, but Scottsdale has no children's museum; the Children's Museum of Phoenix downtown is the other option and a longer drive from most of Scottsdale.
