Transcript of Sydney Opera House

Sydney Opera House Our experiment to show that small seemingly unimportant things can be the inspiration for huge, famous monuments, such as the Sydney Opera House. Meet the Team James Summersby: Came up with the idea of the experiment and all the info on the project. James was in charge of the poster, part of the slide and the interactive presentation you now hear.

Barry Cassidy: The man with the plan, Barry was always the first to come up with the ideas and the solutions. He did most of the typing and was the key to this experiment. Barry typed out the slide show and report book.

JJ Meade: Always there when we needed a hand or a laugh! JJ is reponsible for the oral presentation you now hear, which suits him because he would never shut up along the way! Experiment 1: WW1 Gas mask Our Aims To show how small and unlikrly inventions can be used in the construction of big manmade monuments, such as the Sydney Opera House.
We can show you this through these presentations, experiments and slide shows which will prove our theories.
These theories involve a WW1 gas mask, egyptian wood craft, a collapsible toy Our Inspiration There's not a lot I can really say here. Barry and JJ were the first ones to pitch the idea of doing a project and while I was watching a T.V program about the Sydney Opera House one night, the idea hit me. I did a bit of research and it all came together. I said it to Barry and JJ and they went right with it. It was straight forward from there on in. After failing to qualify for the BT Young Scientest Exhibition we heard of SciFest and we keen to get another chance at glory. Since submiting our entry we have conducted many experiments and have worked hard on the professional presentation you now see. We hope you enjoy reading this as much as we enjoyed making it! Although the huge glass entrance to the Opera House may look stunning, it required a huge amount of planning and decision making before construction could take place. The problem that if one of the slates on one of the arches fell off and hit the glass structure it could crack and colapse, endangering the public to find a solution they looked to a WW1 gas mask. The Connection WW1 gas masks were invented to help soliders in the war from dying of gas explosions.
The eye sockets were made of laminated glass which was stronger than normal glass.
The soliders used this to protsct their eyes from flying debri fron nearby explosions.
Enter connection 1!
The designers used this to their advantage by making the entrance using laminated glass which was stronger and would prevent any falling tiles from smashing the entrance. The Experiment Because it is a reccesion and money is short we will use paper instead of glass.
We attempted to stick a pen through an ordinary piece of paper and then a laminated piece of paper.
We saw that the pen DID go through the ordinary piece of paper and DID NOT go through the laminated piece. Experiment 2: Collapsible Toys When resurecting the tall, magnificent arches which give the Opera House its unique look the designers feared that the weather may knock the arches down. To solve this problem the designers looked to collapsible toys.






Collapsible Toys use cables which are tightend to hold its structure.
Designers used this method in holding up the huge arches. They ran thick long cables through the arches to hold its structure.
The Connection The Experiment We used styrofoam blocks which were stacked and copper wire was ran through it.
We then made another stack of blocks with no copper wire running through it and used it as a control.
We used blu-tach on both to hold the base in place.
We then blew wind at them and saw that the stack with the copper wire running through it held its place while the control flew every where. Experiment 3: Glue for False Teeth The tiles which were used for the arches were heavy and could only be glued on. This left designers with a problem, normal glue wasnt strong enough and would'nt endure the weather. The answer came in the shape of a dentist. The Connection Because they could'nt use normal glue designers looked to glue for false teeth.
Not only was it stronger, but it was more durable and would endure the weather. The Experiment This experiment was pretty easy, we simply glued a piece of string to a brick and hung it from the ceiling.
We did this twice, once with normal glue and then with the glue for false teeth.
We found that the glue for false teeth was better as it did not fall off while the normal glue seperated after just 30 seconds. Experiment 4: Egyptian Woodcraft At the heart of every great theatre is of course the stage where the show takes place, but this left designers with a problem. Utzon wanted it to be made completely out of wood but designers were afraid that it might crack or the end grain might split. Connection Thousands of years ago Egyptians came up with the idea of plywood which was layers of wood stacked perpendicular to each other which was the pressed and glued.
This type of wood was much stronger and more durable as the end grain would not split because they are perpendicular to each other. The Experiment For this experiment we got a sample of normal wood and plywood.
We then tried to hammer a chisel through the end grains of both pieces.
We saw that the end grain of the normal wood did split but the ply wood did not. Experiment 5: Copper Bottom Sailing Ship The most important connection of them all. The Opera house was situated on Sydney Harbour, which is full of salt water and because the base was made out of metal it could erode andcause the opera house to sink into the sea. Connection Copper Bottom Sailing Ships used copper and iron for the base of their hulls like the Opera House.
Copper and Iron are both noble metals which means they are easily eroded.
But copper bottom sailing ships also used another metal, zinc which is a non noble metal which prevents erosion.
This method is called Electroplayting. The Experiment This experiment was the hardest, it involed placing two basins both with salt water and placing a sheet of copper and iron in both and a sheet of zinc in only one of them.
We added electricity to speed up the project.
After one day we saw that the copper and iron on their own had eroded while the copper, iron and zinc together stayed intact. Information About The Sydney Opera House It was completed in 1973.
It was designed by a Danish architect, Jorn Utzon.
He designed it on the back of a napkin during a competition held by the Austuralian government to design a building to attract tourists.
He did'nt make the final but his entry was picked out of a bin.
Construction of the Opera house was halted on several occasions when costs were running high and John Utzon was moving away from the project.
It is situated on Bennelong Point in Sydney Harbour.
It is home to Opera Austuralia, Austuralian Ballet, Sydney Theatre Company and Sydney Symphony.
It has five seperate halls and theatres.
The Concert Hall with 2'678 seats, is the home to Sydney Symphony.
The Opera Theatre has 1'507 seats and id home to Opera Ausuralia.
The Drama Theatre has 544 seats and is home of the Sydney Theatre Company and other shows.
The Sydney Opera House is one of the most recognaisable buildings on the planet. THANKS FOR COMING!!!!!
