Dissecting Geometry Mathematics Excursion

This term 45 enthusiastic students from Year 7 to Year 9 visited the iconic Sydney Opera House for a Maths workshop that explored the intricate geometric elements underlying the design and construction of the world-famous building. Students watched videos, examined sketches, and were treated to a talk from an architect that studied the mathematical beauty woven into every curve and angle of the Opera House.

Throughout the workshop students gained a deeper understanding of the role geometry plays in shaping not only the physical form but also the functionality and feelings associated with the Opera House. They learnt about how Utzon, the Danish architect, was stumped with how to create the famous sails, and how the solution came in the form of a perfect sphere. Students were then challenged to channel their newfound knowledge into crafting their own models inspired by geometric principles.

The budding engineers and architects produced a myriad of imaginative and, in some cases, ambitious models featuring delicate petals, honeycomb tiles, rocket cones and smooth domes. The students are to be commended on the spirit in which they engaged with the activities, as they not only deepened their mathematical understanding, but also sparked their creativity and appreciation for the application of mathematics to the world around us.

“I found the Opera House very educational, inspiring and fun in general. I thought the theory part about the geometric composition of the building was very fascinating. I never knew the Opera House was made entirely of circles! Even better, I gained a lot of inspiration of how to generate design ideas for various buildings, especially using geometric structures and even shapes in nature. Because I want to be an architect when I grow up, this has proved very useful and inspirational. The practical building part was also quite interesting – we had to overcome practical difficulties when building our design of a lotus petal public fountain where the petals wouldn’t curve enough, and they wouldn’t stay on the design. Overall, I found it quite a fun and educational experience.”
