The Da Vinci exhibit was pretty cool.  We got to see replicas of the famous inventions that he made.  Some of these inventions displayed included, The Self Propelling Cart, The Swing Bridge (designed for warfare, the bridge can rotate 90 degrees around a single pin, allowing an army to cross a river, and then prevent their enemy from following.  Leo also drew the really famous painting Mona Lisa and The Last Supper which are the most famous of his paintings. Leo cared a lot about accuracy in paintings, he liked to use techniques of perspective to make distant objects appear smaller and closer ones bigger.  
        Da Vinci was a scientist he was a keen observer of detail, such as subtle differences in skeletal structures. Leonardo's anatomical drawings are remarkable in their detail, even if they aren't as accurate as those based on todays knowledge of the human body.
          Other than the Da Vinci exhibit there was 6 floors in the Science Centre which each had different categories, for example their was a floor with things from space and information about them, also there was an IMAX theatre which we saw an Underwater Life movie and the IMAX screen was huge and the speakers made the sound boom inside your chest. It was a really cool experience that everyone close to Toronto, Ontario should go check out!
          Overall the trip to the Leonardo Da Vinci exhibit was filled with information and I learned many things about famous paintings and Leo's inventions.  The other exhibits were cool also but got kind of boring after a while.  But the IMAX movie was a great way to end a good trip.
