An expanse of 550-million-year-old rock surrounds the geological exhibits at Johnson Geo Centre, a 33,600-square-foot facility that resides mostly in stone’s favourite hangout: underground. There, the Steele Earth & Space Theatre screens high-definition science-minded films in 2-D and 3-D, and the Geo Theatre projects the four-billion-year history of the earth onto a rock wall featuring a cave, running stream, and glowing lava. Exhibitions include scientific oddities such as a cutaway of the earth and 565-million-year-old fossils preserved in layers of volcanic ash. The museum also highlights the educational opportunities found in more recent events: real-life artifacts and interactive kiosks tell the Titanic's tragic story, and the ExxonMobil Oil and Gas Gallery explores energy with scale models of an oil tanker and offshore supply vessel.
At the KidZone, youngsters aged 1–7 can put on science-inspired plays on the puppet-theatre stage or study trilobites and eight-track tapes in the fossil corner. The gift shop also outfits kids with educational books and games, and adults can stock up on agate wind chimes and sterling-silver jewellery. In between bites of Manna sandwiches in the café, members can peruse schedules of numerous monthly events or plan enrollment in summer camps aimed at junior scientists.
