Facilities

IMAX Theatre
A 275-seat theatre showing current educational movies, shot in high resolution IMAX film reel. The Telus World of Science features the original IMAX Theatre in Western Canada. Images are enhanced by a custom designed six-channel, multi-speaker sound system are projected onto a 13m x 19m (4 storey x 6 storey) screen.

In early 2016, renovations had been completed in the IMAX theatre, upgrading it to an IMAX Laser 4K Projector system (one of 3 theatres in Canada).

Admission to the IMAX theatre is not included with general admission. Recently, the IMAX Theatre began showing Hollywood blockbusters (such as Batman v Superman or Zootopia) within a few months after screening in cinemas. As with the educational films, these are not included in the admission price and can be more expensive than the educational films. The Hollywood films cannot be used in the Science Centre + IMAX combos.

Margaret Zeidler Star Theatre
The 250-seat large dome theatre that was formerly used for laser shows and star shows. It was the largest such theater in Canada when the center opened in 1984. In 2008, the Margaret Zeidler Star Theatre changed its projection system and educational content to a full dome immersive video experience. The Telus World of Science Edmonton was the first planetarium and science center in Canada to showcase this new technology for domed theatres. Admission to shows in the Star Theatre is included in general admission. The Star Theatre is additionally equipped with high powered lasers for weekly laser shows.

Purple Pear and Gift Shop
The science centre has a café for visitors and for special events such as fundraisers. The café was undergoing renovations as of early 2016 with an estimated completion by the end of August 2016, though it was delayed until November 2016. The café is also responsible for providing the concession, which is currently hosted in the main lobby, next to the box office.

In November 2016, the cafe re-opened, but under a new name, The Purple Pear and a new focus on fresher, and local ingredients. They were also the first location in Western Canada to use tagged Coca-Cola Freestyle machines.

There is also a gift shop in the lobby, featuring a range of educational products, books, gift items, and other knick-knacks.

Coronation Park facilities

Queen Elizabeth II Planetarium (QEP)- Future 
Built in 1959, the Queen Elizabeth Planetarium was the original home of the science centre. The RASC previously ran the QEP from 1960-1983 until the Edmonton Space Science foundation took over soon afterward. In 2016 the City of Edmonton announced plans to restore the planetarium and grant it full heritage status. On July 1st 2023, the QEP was opened to the public and is now operational.

Observatory
Built the same time as the original Edmonton Science Centre, the Observatory opened its doors in 1984. This outdoor structure is located in Coronation Park and It is free of charge, but it opens only when the weather permits, and it closes if the temperature is below . It is equipped with seven telescopes, including a Meade 16" LX200, a  Starfire refractor, and three solar telescopes all provided by the Royal Astronomical Society of Canada (Edmonton Centre).
