Venue co-ordinator Jessica Davis said it was important to present climate change in a way people could understand in their everyday lives.
A variety of interactive tools were available to help show people what changes were occurring in the environment.
A map with removable ice sheets showed the impact climate change would have on Antarctic in the future.
Virtual reality headsets playing footage of a real Antarctic expedition were available to try.
"It’s about the closest you can get to the real thing without getting on a boat," Ms Davis said.
Lucas Child (7), of Dunedin, tried on an authentic Antarctic researcher outfit, which he said was "very warm" and "hard to move in".
He thought it was amazing that the virtual reality headset could show him what it was like in the Antarctic, but he had no interest in going there himself as he did not like the cold.
The exhibition, which is run by Otago Museum, ends on Sunday.
It was one of many festival events available across the city yesterday.
Another was The Secret Science of Balloonology, a lesson in making balloon animals from a professional "balloonologist" at the Golden Centre.
