Today, the views are still there and just as awesome, as well as a long line of ancient rocks up to four billion years old (the actual rocks aren't that old, but tiny grains in them called zircons are.) The earth is 4.5 billion years old. You may wonder why the oldest rocks aren't that old too? It turns out shortly after the Earth formed, in the violent early days of the solar system, it was hit by a Mars-sized planet and mostly liquified into lava again! The debris launched into space coalesced and became our Moon. It's mind-blowingly daunting and humbling that a human lifetime on this scale is a thousandth of a millimetre, much thinner than a coat of paint!



Space is next, and it's always been that way at the Science Centre. Years ago when I was young, this was my least favorite section (and still is) but we were here and so I made the compromise. The first thing you'll notice is the model of a rocket called 'Saturn V'.

I spent quite a lot of time in Space (and some may agree I sometimes do...), but I didn't learn anything new. In fact most of the exhibits were really kind of boring to me. There were no interactive exhibits at all. One thing I do remember was when they once had the interior model of a rocket ship, with lots of buttons and triggers so give you that feeling of being there. It was fun, and fun to children = learning. At least for me, as a hands-on person, it's sometimes the only way to absorb new things. We did stay for a half hour lecture on 'Extreme Space' . A hundred of us were in a round pod-like Planetarium in which we were shown stars, novas, and galaxies overhead. I chose to lean back on a large bean bag instead of the benches, and found myself in blissful sleep for at least 20 of those 30 minutes...

Now this I've seen before, but never looked into its meaning. I just thought it was a piece of modern art. It turns out it has a very deep and well thought out meaning. It was explained to me like this, 'It's a human figure with the parts of the body sized proportionally to how much of our brain is devoted to them. Notice that one thumb uses more brain-space than both legs and feet!' The plaque at right that should have explained this was removed so if I didn't have anyone to explain this, it would have just been a meaningless and somewhat odd statue!
The place where the statue can be found was and still is my favorite part of the Science Centre. It always felt like a secret hiding place where the real scientific exhibits are seen (the secret stash...) Funny how those old feelings of youth never die. This area is used in the warmer months by visitors as an outdoor patio and scenic area.


In contrast, there are newer areas such as the Weston Family Innovation Centre, and a large play area on the second level that replaced numerous sections of real science exhibits. This area sadly doesn't seem to have any real learning opportunities or demonstrate any scientific principles. It seems like an overt attempt to get parents to bring their kids in without considering that the whole idea of what the purpose of this place is that they will be learning something relevant to their future lives.

everywhere due to the donations and sponsorships required to keep the centre going financially. I don't know for sure, and probably won't look into it, but it seems the visitor headcount has gone down, and so many of the great exhibits that I remember are gone, leaving much empty space (why would they be removed?)
I never liked the looking at the large stump on the right. I can only imagine how many of these giants have been cut down that will never again grow to this size...

Can you tell which is the lightest and which one is the heaviest?
Worlds lightest wood
Worlds heaviest wood (one of them)
These old household implements are surprisingly used to demonstrate that intelligence test are biased, as some assume knowledge of objects, words and ideas that some ages and cultures may be unfamiliar with. I think that most people would probably guess most of them by their appearance. Don't peek, but when you are done writing them down, scroll down to the bottom of the post, where you'll find the answers there.

Here is a very old exhibit that I remember when I was a child. Can you pick the winner of the two discs? If you click on the picture you should be able to read about the outcome and why.

Diagram 2 will show the same principles in a different way. As it turns out, it is much more difficult to spin the 7 and 20 lbs wheels than the 7 and 20 lb. wheels on the left because all the weight is distributed on the outside.

Diagram 3- Open the Gate |
Surprisingly not as easy as you think. There is a trick to it, and I figured it out in less than 5 minutes.....a fun kind of puzzle. Turns out all there is to it is to push down on the post on the far right, which lowers the latch to unlock the gate. But I ask you, is this science or art and design? Maybe the science is Cognitive Science, the study of human perception (and its shortcomings) which is also interesting. It covers psychology, consciousness and perception, and radically influenced Artificial Intelligence. So, yes, this gate belongs here.
Designed and Constructed by James Delgety in 1989.
Finally it closing time and while we were in the basement we found the brain where all of the data from the Science Centre makes its way to this room. It is a central computing hub which helps to run exhibits, computers, screens and displays that are seen throughout the building. Pretty neat huh??
