The Task
Background Information
Colour plays a central role in our visual, imaginative and emotional lives. We attach meaning
to colours, for example red can be associated with anger, war or warmth. The poet Christina
Rossetti captures this notion in her poem:
What is pink? a rose is pink
By a fountain's brink.
What is red? a poppy's red
In its barley bed.
What is blue? the sky is blue
Where the clouds float thro'.
What is white? a swan is white
Sailing in the light.
What is yellow? pears are yellow,
Rich and ripe and mellow.
What is green? the grass is green,
With small flowers between.
What is violet? clouds are violet
In the summer twilight.
What is orange? Why, an orange,
Just an orange!
Another poet wrote about what the colour blue is associated with for him:
Blue is snow on a cold winter’s day
And a breeze is on its way
It is the sound of tears on cheeks
Blue is compassion
And help on its way
And a warm sunny day
It is also waves out on the ocean
And fear coming to play
Blue is a dolphin jumping in the sea
And blue is here to comfort you
The Task
Your task is to create an original poem and artwork that focuses on a colour and what it can
be associated with in life. The poem and artwork must be connected. Before you start, ask this
question: What does the colour smell, look, taste, feel and sound like? You must include the
following components:
A focus on a colour
At least one example of alliteration, a simile and onomatopoeia
A key message connected to this colour
The Materials for the Artwork
Two pieces of A4 paper (One or both can be used)
Coloured pencils or crayons

_____________
Background Information
Leonardo da Vinci understood the power of colour to cartography. He was one of the first artists
to use colour for strategic mapping.
AN EXAMPLE OF LEONARDO DA VINCI’S CARTOGRAPHY WORK!
LEONARDO DA VINCI’S MAP FOR THE TOWN OF IMOLA, ITALY -
YEAR: 1502
LEONARDO’S AGE: 50
Leonardo created a map of Cesare Borgia’s stronghold, a town plan of Imola in order to win his
patronage. When presenting it to Cesare, 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 were holding a piece of land in
the palm of his hand! Cesare hired Leonardo, upon seeing the map as his chief military
engineer/architect.
TASK 1
The use of colours on maps to show “like features” has been used for many centuries. The
coloured maps in Cartography are called Choropleth maps. Your task is to produce a choropleth
map based on average levels of rainfall in Australia and then to interpret this map.
The materials needed for this task are coloured pencils and a pen.
Answer:
Choropleth mapping uses darker and lighter shades of the one colour group to reveal a pattern.
The lightest shade represents the least or weakest presence of a certain element, while the darkest
shade signifies the most or strongest presence.
The map on the next page shows a coded outline of Australia’s average rainfall pattern during
January. Your task is to convert it into a choropleth map by colouring it properly.
(6 Marks for map creation and accuracy)
TASK 2
Study your created choropleth map. Does this choropleth map help you quickly see a pattern?
What is this pattern? (4 Marks)

champion to combat the evil that can plunge the
world into darkness. You and a friend have decided
to audition for the roles of the superhero and the
villain.
Task: 60 second audition
The audition for the film Into the Light requires two
actors to play the roles of the superhero and the
villain. The challenge for the actors is that they will
not be provided with a script and have only 10
minutes to create a short scene for the audition and
60-seconds to impress the director. The actors. To
make the audition even more difficult, the director
wants the actors to include references to light and
darkness. He will be very impressed if this is done
symbolically or metaphorically.

Phenakistoscopes, Ludoscopes and Thaumatropes
Persistence of Vision Toys
Every single day and night, in countries all over the world, hundreds of millions of people are entertained, amused
and engaged because of the knowledge and skills of highly trained engineers and movie makers. Today you will
endeavour to become a Master Builder of Persistence Vision Toys.
Objective:Students are to build a fully functioning Ludoscope (a Phenakistoscope without a mirror). The winning design is
the one that works properly, is easy to operate, enables simple and effective change of image disks, is well made
and looks professional.
Materials:3 image disk sheets, 4 sheets of A4 paper, 2 plastic straws, 4 pipe cleaners and a 30cm length of wooden dowel
Equipment:1 pair of scissors, 4 coloured pencils, 1 small roll of sticky tape
What to do:Students are to closely study the images of the Ludoscope in the background information sheet. They are to use
these images together with the knowledge that they glean from what they have read to design and construct a fully
functioning Ludoscope. Marks will be awarded for function, ease of operation, interchangeability of disks,
presentation and the completed questionnaire.
Time allowed to complete the construction will be 45 minutes. No further construction or answer time will be
permitted after the 45 minutes are up.
Scoring:10 points will be awarded for function (it works properly)
10 points for ease of operation (easy to see images, disk spins freely, easy to hold/support during operation)
5 points for interchangeability (can swap/change disks easily)
5 points for presentation (it looks good and is well made)

TOTAL: ________ / 40
The Phenakistoscope
The optical toy, the Phenakistoscope, was an early animation device that used the persistence of vision
principle to create an illusion of motion. It was invented by Joseph Plateau in 1841.The Phenakistoscope
used a spinning disc attached vertically to a handle. Arrayed around the disc's centre was a series of
drawings showing phases of the animation, and cut through it was a series of equally spaced radial slits.
The user would spin the disc and look through the moving slits at the disc's reflection in a mirror. The
scanning of the slits across the reflected images kept them from simply blurring together, so that the user
would see a rapid succession of images that appeared to be a single moving picture. A variant of it had
two discs, one with slits and one with pictures; this was slightly more unwieldy but needed no mirror.
This device was called a Ludoscope. Unlike machines such as the Zoetrope and its successors, the
Phenakistoscope and Ludoscope could only practically be used by one person at a time.
Like the zoetrope this toy uses a series of images viewed though slits to create the animation. It differs
from it because the images and slits are on rotating disks rather than in a drum. If the picture disk and
disk with slits are back to back it is held in front of a mirror and the images are viewed in the mirror
through the slits. The 19th century set on the right below is of this type. A variation, sometimes called a
stroboscope, mounts the picture disk and the disk with slits separated on a spindle so that the pictures are
viewed directly through the slits.
On the left below is an early 20th century "Motion Picture Show" or "Ludoscope" which came in its box
with a set of discs.
Below is a "Gramophone Cinema" that dates from the 1920s. An illustrated disc site on the top of a
record and a disk with slots rides on a wooden spindle with rollers over it. As the record turns the
animation can be seen through the slits. The cards include Felix the Cat and a Charlie Chaplanesk tramp.
The following is a trade card that shows the two sides of a bird and cage image while a boy illustrates the process
of spinning the cards to unite the images. The combined image is seen below.
Below you see the two sides of an early 20th century thaumatrope of a horse and circus bare back rider
and an animation showing the merged images.

Gabby’s Dream
Gabby slipped out of her bedroom window in the middle of the night to ride her
pink unicorn over a rainbow to the Land of Twirls and Whirls. When she arrived
she slid up the slide, did a complete loop on the swing (and they said on
Mythbusters that it was impossible), played leapfrog with gigantic spotted frogs
and danced Gangnam Style with the entire cast of the original Wizard of Oz movie,
including the Wicked Witch and the flying monkeys.
After lunch she went cloud surfing with her fairy
godmother who was dressed entirely in polka dots and
wearing army issued combat boots. Gabby then played
tennis with Buddha whom she beat comprehensively
because he was seriously overweight and had forgotten his
tennis racket.
Then things started to get seriously weird. Finally she had
a bowl of chocolate ice-cream and tomato sauce but as
time was running out, she took her bowl of ice-cream with her while her pink
unicorn returned her across the rainbow safely to her bedroom. In the morning
Gabby’s mother woke her and told her to get ready for school. Looking at Gabby’s
bedside table her mother shook her head, sighed and said, “What have I told you
about eating ice-cream and tomato sauce in the middle of the night?” Gabby
opened her eyes and looked over at the gooey lump of ice-cream and tomato sauce.
Her eyes widened to the size of dinner plates.

REFERENCE SHEET ABOUT LIGHT
•
•
•
Light ALWAYS travels in STRAIGHT lines.
The angle of INCIDENCE (entering light rays) equals the angle of REFLECTION (leaving
light rays).
The angle of INCIDENCE (entering light rays) equals the angle of REFRACTION (leaving
light rays).
Path of light rays reflected off mirrors
Flat Mirror
Path of light rays through lenses
Concave Lens
Convex Lens
Your Task – The torch
Use the reference sheet on light and the diagram of a torch below as a guide to complete the
tasks.
Part A
1) What shape of reflective surface would be required for a flood light (this light covers a large
arc and has a wide beam)?
2) What shape lens could be used to make the light rays in the flood light spread out even
further?
3) What shape of reflective surface would be required for a thin beam of light?
4) What shape lens would be needed in a torch to make the light focus for a surgeon’s head
light?
Part B
Below is an advertising diagram of the Sport Light 170VP, from Deben.com.
Explain how this torch works to enable the light beam to be adjusted from a thin beam (spotlight)
to a wide beam (floodlight).
Your answer should demonstrate knowledge of reflection using mirrors and refraction using
lenses.

Part A – (1 mark each)
1) Convex mirror
2) Concave lens
3) Concave mirror
4) Convex lens
Part B – The Deben Sport Light 170VP, adjustable torch
(5 marks – 1 for reflective surface, 2 for flood and 2 for thin beam light describing how the lens works)
To make the beam spread out to a flood light
•
•
There will need to be a concave mirror inside the torch head. This mirror will be fixed in position. It will
be there to simple reflect light out wards from the globe. It will be the lens that will spread the light
more. (they may think that the mirror is also an adjustable shape from concave to convex – I do not
know for sure)
There will be concave lens. This lens will be the shape of the glass on the outside of the torch. The torch
will always be a flood light unless changed.
To make the beam spread out to a thin beam light
•
•
•
The mirror will not move and is there to simple reflect light.
The dial will move second lens, which will be convex. This will adjust the beam of light to the desired
width.
There may also be a lens cap / shield on the front of the torch that may cover part of the glass to make
the light even more focussed.
1) They must state that there reflective surface inside that will reflect the light from the globe. It is most
likely concave shaped.
2) They must state about the beam for the flood light going outwards and there should be a concave lens,
this lens will be fixed.
3) To make the bean thinner they must state about a moveable convex lens; that will change the width of
the beam, focussing it to a thin beam.
