FINAL TASK

Create your own New York skyline in the classroom.1- Study one of New York's iconic skyscrapers:One World Trade CentreChrysler Building,Empire State Building....Guidelines :Where is the skyscraper located?When was it completed? How long did the construction take?How tall is it?What materials were used in its construction?Who was the architect who designed the building?What were some of the goals the architect was trying to accomplish? Do you think he or she succeeded in meeting those objectives?Was it ever the tallest building in the world? When, if ever, did it lose its title? Where does this building rank today among the tallest in the world?What materials or technology enabled it to surpass the heights of previously constructed skyscrapers?How many people visit this skyscraper each day/week/month/year?What were some of the challenges involved in building it?Were any people injured or killed during the building process?What are some important events that took place in this skyscraper?2- Create an illustration, drawn to scale, of it on a piece of poster board. Each group should use the same scale, such as 1 foot of illustration = 100 feet of actual skyscraper. At the bottom of the illustration, include a stick figure of a 5-foot person for size comparison.3- Create an index card with basic facts about the building (name, year built, location). Then write 5-10 fun facts about the building on sticky notes and post them around their illustration.

Together think about the motivations to build skyscrapers.Why ?What were the needs at the time ?What were the difficulties ?[need for more room as population growing and spatial constraints as NYC an island]

[0’00 – 0’30]Check your ideasCan you guess what he is talking about : « We lacked one key piece of technology » ?[0’30 – 0’50]Watch and check your ideas.What problem did it solve ?Watch the rest of the video and take notes about (in groups)The problem with the elevator beforeHow this problem was sortedThe impact of the elevator on urbanizationThe reactions

Read the textComplete the drawing with the appropriate captions.

SPAGHETTI TOWER CHALLENGEBuild the tallest, freestanding tower using 10 spaghetti and 4 marshmallowsTeams of 32 minutes to create a rough sketch and plan for your structure.5 minutes to build your tower.

THINKWas your tower successful?If you did this again, what would you do differently?What are the difficulties engineers have to face?How can we solve them ?Check with the video.

Read one of the texts and note down what you understand.In pairs, discuss with your partner and refine your ideas.Meet another pair of students and together exchange about the engineering challenges.To conclude, complete themindmap.

SPEAKING TASK:You are a team of tour guides in NYC. Prepare the speech you will deliver in the « Remembering 9/11» Tour.Be ready to answer questions for the tourists.

Sort the pictures into two groups.Decide on one or two criteria you used to distinguish the structures from one another[SKYSCRAPERS & OTHER BUILDINGS]

Are all tall buidings skyscrapers ?What are the criteria ?

Determine whether the tall buidlings pictured on the document exhibit the characteristics of skyscrapers.Include a written justification for your decisions.
