Clark Planetarium

Clark Planetarium is a strong indoor choice when children want to touch, build and experiment instead of only looking at displays. Admission to more than 10,000 square feet of exhibit space is free. The exhibits cover three floors and move from Earth science into the solar system and deep space.

Children can make a crater, watch a seismograph respond to a jump, study infrared images and try activities about weather, ice and gravity.

The third floor has some of the clearest kid appeal. Families can step into an area modeled after Io, one of Jupiter's moons, and use simple programming to control a rover. The Northrop Grumman Exploration Space includes a children's climber, a lunar lander activity, a magnetic storytelling wall and a station where kids mix fuel and oxygen to launch a model rocket.

Older children may spend more time with the black-hole, wavelength and planetary-science exhibits. Toddlers can still push buttons and explore the physical displays, but much of the science will land better around age 4 and up.

The free galleries make a 90-minute visit possible without committing to a full day. Adding a Hansen Dome or IMAX show can stretch the outing to three or four hours. Those theaters require paid tickets, and showtimes vary, so check the current schedule before leaving home. The building is fully indoors and works well during rain, snow or summer heat.

Arrival is fairly direct once you know the setup. Clark Planetarium is inside The Gateway, with underground parking entrances that connect to the building. Discount parking validation is available at the ticket desk and gift shop.

A UTA rail stop is also directly east of the front door. Families with sensory needs may prefer Saturday from 9:30 to 11:30 a.m., when lights and sounds are adjusted. Sensory equipment is available at the ticket counter.

The official visitor information does not confirm stroller rules, nursing facilities, changing stations or on-site meals, so verify those details before a visit with a baby.
