Task developed by Karen Yager, Knox Grammar School 2014

Creative Producers Background Information

Throughout history there have been reported sightings of strange creatures – cryptids whose existence has not been verified by scientists. Those who claim to have encountered these mysterious creatures have been intrigued and terrified. The Loch Ness Monster has eluded attempts to verify it existence since it was first reported in the 7th century. In Australia, the bunyip and the yowie have been written and spoken about as far back as the beginning of Aboriginal mythology. Task: 60 second Dramatic Performance The team’s challenge is to create a 60-second dramatic performance that is based on an encounter with a mysterious cryptid. The performance can be in any genre. It could be a dramatic monologue, an action adventure skit…it is up to the team to decide. Each group will have ten minutes to prepare for the presentation. Marking Criteria You will be marked on the basis of the following criteria:

Physicality and voice /10 Coherence – structure /10 Dramatic communication of ideas /10 Flair /10 Imaginative use of the cryptic /10

A warning will be given at 55 seconds and the presentation will be stopped at 60 seconds.

Philosophy – Answers

With the philosophy paper there are no right answers per se. What we should

be looking for are intelligent, thought out, considered and eloquent responses.

However, there are some philosophical considerations that we might take into

account while marking.

Q1 – What gives humans the right to impose our law on other species? For

every human killed by a shark, approximately two million sharks are killed by

humans.

Q2 – The age old philosophical conundrum. A chicken cannot be born without

an egg and an egg cannot be laid without a chicken. Did the chicken perhaps

evolve from an animal that gave birth to live young to an egg laying one?

Q3 – Look for arguments about how limiting the vote to only educated people

would create both an elitist class and a disaffected under class.

Q4 – Beauty is subjective. As Andy Warhol pointed out, everything is art, even

a soup can.

Q5 – Despite our looking to and listening to our universe, we have only

searched a fraction of it. The chances of life being out there somewhere in our

universe is a mathematical certainty.

Engineering Challenge Suspension Bridge

Blurb on bridges

Everyday around the world, bridges are used daily by millions of people. When driving onto a bridge, people put trust that the bridge will support their weight and will be safe to cross. This is only made possible by the hard work of Engineers.

Objective:-

Students are to build a suspension bridge. This bridge is to be an minimum of 30cm in length, the bridge must be 4 straws wide and a minimum of 10cm high.

Materials Provided:-

20 DRINKING STRAWS, 30cm MASKING TAPE, 2m THREAD, 4 LARGE PAPER CLIPS, PAPER CUP

Equipment Needed:-

Scissors, Pen/Pencil and ruler

What to do:-

Using two chars, students are to create a suspension bridge. 30cm in length, the bridge must be 4 straws wide and a minimum of 10cm high. The aim is to create the strongest possible bridge to be tested with weight suspended from the deck. You will need to attach your bridge to the two chairs using the masking tape. Your group will need to attach the paper cup to the middle of the deck of the bridge for testing as weight will be added to the cup for testing.

Scoring:-

Score will be based on the number of marbles your bridge can suspend.

Bonus marks will be given for aesthetics.

1. Description

o The suspension bridge is easy to recognize for its slender, distinctive shape. Most suspension bridges have two long pairs of long, narrow towers with cables hanging gracefully between them. These main support cables are strung with smaller, vertical cables to hold up the main bridge deck. The main cables descend into supports at either end of the bridge, often holding up two smaller decks to the outside of the main towers.

How It Works

o The main cables are strung with vertical cables that attach to the deck. These cables support the deck of the bridge, transferring the weight to the towers at the end. The main cables continue past the tower, and are anchored past the far ends of the bridge. They are carefully balanced so that the force pulling inward on the towers is equal to the force pulling outward. As a result, the weight pulls directly down into the base of the tower. The towers can be fairly thin, since they aren't being pulled to either side. The deck can also be thin, since it is being supported by the cables.

o

Design Problems and Solutions

o Suspension bridges have a few weaknesses that have caused disaster in the past. One of the most serious problems is the main cable. Early suspension bridges were sometimes made using chain links of heavy steel for the main cable. If only one chain link failed, the whole bridge would collapse, as what happened to the Silver Bridge in 1967, killing 46 people. Nowadays, suspension bridges use bundles of cables. If one or two of the cables fails, the bridge still stays intact.

The Tacoma Narrows Bridge was a more famous and spectacular lesson in design. The deck was not thick or stable enough, and would start to oscillate in a moderate wind. Eventually, in a fairly heavy wind, the bridge shook itself apart. Nowadays, suspension bridges are built with a more thick and rigid design to prevent excessive motion.

NSW da VINCI Decathlon

ENGINEERING CHALLENGE QUESTIONS

1. Why is it important that the force pulling inward on the towers

is equal to the force pulling outward?

So that the towers stay rigid and do not crumble.

2. Explain why modern suspension bridges use bundles of cables.

A contingency plan, incase one of the cables snaps, the bridge

maintains its structure.

3. On the diagram below use arrows to show the direction of

forces on a suspension bridge.

4. Give two reasons why early suspension bridge designs proved

to be flawed.

1) They were too light and would be affected by the wind

pressure.

2) Using only single cable / chain.

5. Deck trusses like the one above are frequently found on

modern suspension bridges (see picture on second page of your

booklet) because their design resists the twisting forces. Why is

that important for a suspension bridge?

It is to stop the twisting motion and to provide extra weight, to

overcome wind.

6. The ANZAC bridge below is located in Pyrmont in Sydney. How

is it different to a normal suspension bridge?

The bridge has no deck truss.

The cables connect directly to the deck.

There are individual cables for each connection.

7. The Sydney Harbour Bridge above, is known as a through the

arch bridge. Like a suspension bridge its deck is suspended, and

it also has towers at both ends, but for a very different reason.

Explain the purpose of the towers on the Sydney Harbour

Bridge.

The only purpose for the towers is aesthetics (appearance)

8. What might be some of the advantages of the Sydney Harbour

Bridge over a suspension bridge of similar length.

Creates a stronger structure

Less vulnerable to wind

Saves on costs

Task: Mystery and Mayhem of Books Background Information: Books transport us into other worlds and spark our imaginations to

create images in our minds of the worlds they take us to and the characters we meet. Many books present stories that engage us with their exploration of the mysteries in the world and the mayhem that can arise. The Adventures of Tom Sawyer, The Lion, the Witch and the Wardrobe and Alice in Wonderland

are just three books that have enchanted readers since they were written. What book has inspired you to visualise its world and characters? If you were asked to write a poem and accompany it with a visual what would you create? Look at the examples provided. Your Task Your challenge is to create an original poem and artwork that have been inspired by a book you have read that deals with an adventure that immerses the characters in mystery and has elements of mayhem. Your poem needs to capture the mystery and mayhem of the book. The accompanying artwork that must be a 3D-scultpure made out of paper has to be clearly connected to the content and ideas of the poem. You can use sticky tape but remember that too much will spoil the appearance of the artwork. You must include the following in your poem:

Cartography Challenge

‘Without maps all is lost’ (Anonymous).


2

BACKGROUND: LEONARDO DA VINCI MAPS AND HIS CARTOGRAPHY WORK

Cartography is the process of map making and is another subject area that Leonardo mastered!

EXAMPLE: CHIANA VALLEY, TUSCANY (AD 1502)

This map of the Chiana Valley in Tuscany was created by da Vinci for his patron Cesare Borgia to hand him an advantage of having an overlay of the land during times of war. Da Vinci took special care to record all the rivers to give his patron the greatest strategic tool possible.

When presenting it to Borgia, the powerful leader must have been left in a state of awe. People at the time had hardly heard of maps let alone seen one. Maps themselves held a magical feel to them at the time, as it would have seemed as if one was holding a piece of land in the palm of his or her hand! Borgia hired da Vinci upon seeing the map as his chief military engineer & architect.

TASK 1 – Creativity (20 marks)

It’s time for you to aspire to da Vinci’s level of creativity!

1. You are to create a map of your own imaginary country. Be sure to include all of the following:

a theme; a relevant country name; and an appropriate shape for your country.

For example: If you choose a “games” theme…

3

You might name your country Gameville or Gameland. Your country could be in the shape of a playing card or a dice. The capital might be named Othello, Uno, or Gameopolis. The desert might be named Dominoes Desert or Dice Desert and a marsh might be

called Monopoly Marsh. The products your country manufactures might be chutes and ladders, dice or mouse

traps. The natural products might be a forest in order to have paper to make cards, oil wells

to make plastics for the game pieces, or a cocoa bean plantation to make chocolates for Lolly Land.

2. Be sure to include (name and symbol) the following items on your map:

A title (large and neat) A compass rose A scale (in kilometres) A capital city (marked with a star) 5 other cities (marked with a dot) 3 natural resources and 3 products and a legend that gives the symbols for each 5 physical features

3. Final directions you must follow:

Your team name must be in the lower right hand corner of the map. Your map must be coloured with coloured pencils and outlined in black felt-tip

marker. Your map must be done neatly and be of the highest quality of work.

4

TASK 1 – Creativity (20 marks) Draw your Map here.

5

TASK 2 – Choropleth mapping (15 marks)

Leonardo da Vinci understood the power of colour to cartography. Choropleth maps help break down a lot of information into groups. Colour is then used to display the information to help give the reader a quick impression of the pattern.

1. Create a choropleth map

a. Select three colours in the same colour range, e.g. dark brown, mid-brown and yellow. b. Examine the appendix “Life Expectancy Statistics in Africa” (back of this paper). Use the data to draw your own choropleth map of life expectancy in Africa on the map of Africa on the following page. c. Locate the column for life expectancy and place a ruler or sheet of paper next to it to block out some of the other information. d. Find the countries where life expectancy is under than 50 years. Colour these in the lightest shade. e. Find the countries where life expectancy is between 50 years and 70 years. Colour these in the middle shade. f. Find the countries where life expectancy is over 70 years. Colour these in the darkest shade.

6

2. Look carefully at your completed map.

a. Give one example of a country in the following categories: Over 70 years _______________ 50 to 70 years _______________ Under 50 years _______________ b. Describe the pattern on your map. Use direction to help you, i.e. in the north of the continent, in the south of the continent, in central Africa.

i. The countries with an average life expectancy over 70 years are generally found _______________________________________________.

ii. The countries with an average life expectancy under 50 years are generally found _______________________________________________.

iii. An exception to the pattern is _______________________________. TASK 3: CITY ANAGRAMS (15 marks)

1. Your task is to unscramble the following words to reveal each well-known city.

RASIP __ __ __ __ __ GIJNIBE __ __ __ __ __ __ __ SCOOMW __ __ __ __ __ __ ONLDNO __ __ __ __ __ __ YYSEND __ __ __ __ __ __ MAJLSEERU __ __ __ __ __ __ __ __ __ SNITBLAU __ __ __ __ __ __ __ __ NKUCLADA __ __ __ __ __ __ __ __ TOLNMARE __ __ __ __ __ __ __ __

7

HOCCIAG __ __ __ __ __ __ __ TAAKRAJ __ __ __ __ __ __ __ SOOL __ __ __ __ Bonus: Using the boxed letters from your answers above, list the city that will be hosting the Games of the XXXI Olympiad.
