Science North is an outstanding muti-storey zoo and science museum in Sudbury. Its buildings are connected by a skywalk with natural sunlight and a tunnel that goes through a geological fault from more than a billion years ago. The fault was discovered only when the museum was being built and incorporated as an exhibit.

The interior of the museum has a ramp connecting all four levels to make it a seamless vertical visit. Apollo astronauts visited Sudbury to see its biological faults and the Queen opened the building to the public in 1984.

There’s an exhibition area with insects and a butterfly enclosure. The staff said that they actually breed spiders and insects in the museum and give some of them away when they have too many. They also walk some of their mammals around the museum regularly and I saw a porcupine called Maple being let out of her enclosure.
The museum is highly interactive with regularly scheduled activities at stations all around the building. My favourite was the CPR challenge and I think all science museums should teach visitors the importance of receiving CPR training.
