We spent about 4 hours here yesterday, and left only because they were closing. There is so much to see and learn! The Titanic exhibit was very thorough and interesting. Yes, one could read any number of books and gain the same knowledge, but the displays and models made it a much broader experience. There is even a room with iceberg “aquariums” that really put these big chunks of ice in perspective! We spent a lot of time, and read every board. If you don’t want to take that much time, the regularly scheduled staff tours are great, as the tour guide provides a summary of the story as you move through the exhibit. The many rocks on display are very interesting - IF you’re interested in how rocks are formed and seeing samples of each type. There are also exhibits about plate tectonics and the history of earth and life on earth that I found very fascinating. Then you move on to space exploration exhibits. This wasn’t very detailed, but it was nice to see the progression from billion year old rocks to space travel. My only disappointment was the lack of information/exhibits about the ocean floor. There was just a minor display, and considering Newfoundland is an island, AND the majority of Earth is water, I felt emphasis could have been expanded. There is a very small exhibit about sponges, however. If you want to understand the “how and where’s” of oil drilling, there is a very detailed exhibit to satisfy that curiosity. Overall, the Geo Centre is a well designed and fascinating place.
