Singapore's iconic landmarks

Dear students,

After writing your reflection, please read the following about the Singapore Flyer, Marina Bay Sands Singapore and the floating Platform @ Marina Bay. Lastly, the map shown gives you an impression of their  respective locations.

All these information is needed for you to solve Stage 2 of your Webquest during the next lesson! Have fun exploring!

Enjoy your weekends :)

Fun Facts about the Singapore Flyer
How many men lying from head-to-toe make up the diameter of the Flyer? Just exactly how tall is the Flyer? Discover some fun facts about Singapore Flyer.
Vital Statistics
Diameter: Singapore Flyer is 150 metres in diameter – about the length of 87 Singaporean men lying down head-to-toe. The average Singaporean man is 1.72m tall.

Height: Singapore Flyer measures at 165 metres in height – about the height of a 42-storey building. To amuse your child, describe the height as "31 male giraffes stacked on top of one another". The average height of a giraffe is 5.3 metres.

Land area: Singapore Flyer stands on 33,700m2 or 363,000 ft2 – an area that will fit 172 tennis courts or 1,120 parking lots. A typical parking lot is 30m2.

Capsule size: Each capsule is 4 metres x 7 metres – about the size of a city bus. There are 28 capsules. Each capsule can carry up to 28 passengers.
Speed it travels: 0.24m per second, or 0.76km/h.
Total capacity per revolution: 784 passengers.  

Boarding & Flying
Boarding: To board the capsule, you use the “step on platform” - it’s like walking on level ground into the capsule. There are two synchronised doors and two platforms on each side – making it easy for the elderly and those in wheelchairs to get on and off.

Rotation: Each rotation is about 32 minutes.
Smooth Rotation: Singapore Flyer is designed and built to rotate smoothly under various wind conditions at high altitudes – thanks to precision wind engineering.

View Radius: On board Singapore Flyer, you can see up to 45 kilometres away – that’s 3 kilometres more than the entire length of our island city. From the Flyer, you’ll be able to see Changi Airport, Sentosa Island, and even parts of Malaysia and Indonesia.

Design & Technology
Design: Singapore Flyer is the brainchild of world renowned architect Dr. Kisho Kurokawa (Japan) and architectural firm DP Architects (Singapore). The design is notably "avant-garde" – experimental and innovative while emphasizing simplicity and harmony.
Technological Wonder: Singapore Flyer uses a slim ladder truss rim – not the usual triangular rim used

by other observation wheels.

Marina Bay Sands Sky Park

The Sands Sky Park is an architectural masterpiece sitting on top of the three hotel towers at Marina Bay Sands. This 1.2 hectare tropical oasis is longer than the Eiffel Tower is tall and large enough to park four-and-a-half A380 jumbo jets. It extends to form the one of the world’s largest public cantilevers.
The Sands Sky Park is an awe-inspiring engineering wonder. This unique structural masterpiece, designed by visionary architect Moshe Safdie, floats atop the three soaring Marina Bay Sands hotel towers 200m in the sky.
Stretching longer than the Eiffel tower laid down or four and a half A380 Jumbo Jets, with an impressive 12,400 square meters of space, the Sands Sky Park can host up to 3900 people. The gravity-defying cantilever is one of the largest of its kind in the world. From this privileged observation deck, hundreds of visitors at a time can feast their eyes on the unforgettable panorama view.
  • 200 meters in the sky
  • Landscaped gardens are home to 250 types trees and 650 types of plants
  • 12,400 square meters of space big enough to fit three football fields
  • Exclusive restaurants including The Sky on 57, helmed by Singapore’s celebrity chef Justin Quek
  • A spectacular public observation deck that can host hundreds of people
  • A 150-meter infinity swimming pool, the world’s largest outdoor pool at that height
Floating Platform @ Marina Bay
The Float at Marina Bay, stylised as The Float@Marina Bay and also known as the Marina Bay Floating Platform is the world's largest floating stage. It is located on the waters of the Marina Reservoir, in Marina Bay, Singapore.
Made entirely of steel, the floating platform on Marina Bay measures 120 metres long and 83 metres wide, which is 5% larger than the soccer field at the National Stadium. The platform can bear up to 1,070 tonnes, equivalent to the total weight of 9,000 people, 200 tonnes of stage props and three 30-tonne military vehicles. The gallery at the stadium has a seating capacity of 30,000 people.
The floating stadium will be a venue for events on the waters of Marina Bay for five years from 2007. These events may include sports, concerts, exhibitions, and the arts and cultural performances. The National Day Parade will also be held annually for five years at the stadium, which is meant to be an interim venue in place of the National Stadium until the Singapore Sports Hub at Kallang is completed in 2014.
This stadium is part of the Marina Bay Street Circuit Turns 17 and 18, which hosted the Formula One Singapore Grand Prix. More famously, it was where Nelson Piquet, Jr. crashed his car which led to the Renault Formula One crash controversy.
Following Singapore's successful bid to host the inaugural 2010 Summer Youth Olympics, the floating stadium will be under the spotlight during the Games, having chosen as the venue for the Games' opening and closing ceremonies.

Reflection Task 1 and Homework 1

Dear students,

This is an individual graded assignment.
  • Please complete the homework and submit it during the next lesson 
  • Please submit 1 post before this Sunday 2300. Also, please feel free to comment on your peers' reflection.

After the first lesson, you have learnt on trigonometric concepts of,
1) bearings
2) angles of elevation and depression
3) area of triangle formula
4) 3-D trigonometry. 

Homework 1: Refer to your Textbook page 71, Exercise 7A and complete questions 1, 2, 4, 5, 6. Page 74 Exercise 7B and complete questions 3, 5, 7, 11.


Reflection task 1: Choose any 1 of the above mentioned concepts and write on how does that chosen concept apply to your daily life? From your hobbies, observations of daily routine work, this task encourages you to think about the real-life applications of the above concepts! So be as creative and relevant as possible! You are free to use diagrams and post websites to substantiate your reflection and share with your classmates. 



      Thank you!

      Greetings!

      Congratulations to you on finishing Stage 1 of your Webquest! I must say all of you have put in a lot of effort to work together as a group. I hope you have fun exploring the various mathematical websites and creating your mind-map :)

      As mentioned in class, I will be giving you a reflection task to post here. Each of you must submit 1 post by this Sunday 2300. All of you are very welcome to comment on your classmates' posts. Stay tuned for more information!
