Disinfectant and bacteria investigation

Aim:
I want to investigate how different disinfectant concentrations can affect the reproduction and growth
of micro-organisms, bacteria.

Hypothesis:
My hypothesis is, the more concentrated the dettol the more bacteria it will kill.

My hypothesis is, the more concentrated the dettol, the more bacteria that will die, meaning a larger
clear zone.

Variables:

Independent Variables:
The variable that I will be changing is the concentration of the disinfectant I will do this by adding the
same amount of disinfectant to different amounts of water to change its strength.
I will use:

• Full strength dettol
• Manufacturers instructions
• No dettol - just water
• Diluted dettol

Dependent Variable:
The variable that I will measure is the size of the clear zone around the Dettol disk.

I will measure the diameter of the clear zone by using a ruler.

Other variables:

Other variables that can change the outcome of the experiment are:

• Growing temperature - we need to grow bacteria in the same temperature for each.
• Same environment - We need to grow the bacteria on the same medium (Seaweed jelly)
• Growing time - We need to grow the bacteria for the same amount of time.
• Size of the disc - we need to make sure we have the same amount of dettol .
• The age of the dettol, the length of time the seal has been broken i.e. shelf life

Reliability

To ensure reliability I will repeat the experiment three times.

Method:

Step 1
Gather the equipment

• Dettol

• Vivid - for labeling

• Filter paper

• Water
• Salatape
• Agar plate
• Hole punch
• Bacterial solution, a solution of bacteria
• Pipette
• Tweezers

Step 2
Get the filter paper and cut out 4 disks with the hole punch.

Step 3
Using your vivid, mark out the agar plate into four quadrants (sections), label each quadrant so you can identify which section is which, do not label the lid, label the bottom of the agar plate.

Step 4

Using the pipette transfer some of the bacteria solution onto the agar plate.
Swirl the bacteria around in the agar plate, with the lid on, to cover all the surface.

Step 5
Tip out the excess bacteria solution in the agar plate into a sink, do NOT rinse agar plate.

Step 6

Using the tweezers, pick up the disc and dip them into the water, shake off any excess drops, and a
place it into the appropriate quarter.

Step 7
Using the tweezers, pick up the second disc and dip them into the dettol, shake off any excess drops and place it into the appropriate quarter.

Step 8
Make up the next solution in a measuring cylinder, put 400 ml of water in the cylinder and one cap full of dettol. Mix together and pick up the third disc, dip them into the watery dettol, shake off excess drops and place into the appropriate agar plate quadrant

Step 9
Make up the last solution in a measuring cylinder, put 800 ml of water into the cylinder and one cap full of dettol. Swirl to mix together and pick up the third disc, dip them into the watery dettol, shake off excess drops and place into the agar plate quadrant

Step 10

Name the side of the lid and tape the lid onto the agar plate.

Step 11
Incubate at 20 degrees, upside down. Leave it over the weekend and come back tuesday!

Step 12
Repeat 2 more times so you have 3 results.

What happened?
During our test, bacteria was able to grow in the environment given. But due to the dettol, bacteria was killed off, the clear zone increased with the larger amounts of concentrated dettol added.

How does this happen?
During the process, dettol seeps into the bacteria and breaks down the cell wall, seeping right into the cytoplasm. The chemical in dettol, Chloroxylenol, stops the bacteria from producing ATP (produced by proton gradient distributor), Adenosine TriPhosphate or ATriPhosphate. ATP is the energy storer, it responds to the bodies need for energy, i.e. moving, breaking, or eating, this stops the bacteria from reproducing and gathering nutrition, promptly starving the bacteria to death. The ATP’s are produced by proton gradient distributor, by shutting this down ATP can not be produced.
The enzymes within bacteria gets shut down, the particular enzymes that are able to degrade down nutrients, organic materials, such as fats, oils, cellulose (an organic compound with multiple linked glucose units), xylan (found within plant cell walls and some algaes), proteins, and starches, are shut down due to the chloroxylenol within dettol. This will also stop the bacteria from being able to gather nutrients, again, promptly starving the bacteria to death.

What chemical in dettol kills the bacteria?

The chemical in dettol that kills bacteria is called Chloroxylenol, what is also known as para-chloro-meta-xylenol, and antiseptic chemical used to disinfect skin, cleaning surgical instruments and surfaces. Chloroxylenol contains the chemicals C8, H9 and CIO.

Chloroxylenol is not toxic to humans, non toxic to birds and is moderately toxic to freshwater invertebrates (Animals that do not possess vertebrate columns (Spine)). The chemical is known to be dangerous to cats, and is extremely lethal to the cane toad. The chemical was banned from being used as pest control in western Australia due to concerns of flora and fauna potentially being harmed.

What is a cell wall?

A cell wall is a structural layer that some cells have, the bacteria we studied, a typical gram positive bacterium, has this layer. In this bacteria, the cell wall resides underneath capsule, the outer layer.
The cell wall is what bacteria uses as protection, it being a key part of its survival. It provides the
bacteria structure, it also stops water from rushing into the bacteria and disrupting the large amounts
of protein they contain. The thickness of a cell wall can help identify weather the bacteria is gram
positive (Thicker cell wall, dettol being more effective on this type) or gram negative (Thinner cell wall,
dettol being less effective on this type), identification of this is called Gram Staining.  

The cell wall protects the bacteria, it determines what goes in at what goes out of the bacteria.
Although this effective, bacteria cell walls have holes in it, these holes are what allowed dettol to enter
the bacteria's system.

Capsule

The cell capsule is a well organised layer, the layer is the resides above the others. It is the cause of
various diseases, such as salmonella, this is done by enhancing the ability to create and spread the
diseases. The capsule is found in both gram negative and gram positive bacteria.

The cell capsule is a well organised layer, the layer is the resides above the others. It is the cause of
various diseases, such as salmonella. The capsule is found in both gram negative and gram positive
bacteria.

The capsule can protect the cell from engulfment by eukaryotic cells (A type of cell with a nucleus
enclosed within membranes)

The capsule is made up of polysaccharide, a carbohydrate with molecules consisting of a number of
sugar molecules bonded together. The background, surface, that the bacteria resides on is stained
darker than the bacteria. The capsule is the light, either pale or colorless, residing as the outer layer
like a halo or ring.

Cell wall

bacterium, has this layer. In this bacteria, the cell wall resides underneath capsule, the outer layer.

The cell wall protects the bacteria, it determines what goes in at what goes out of the bacteria.
Although this is effective, bacteria cell walls have holes in it, these holes are what allowed dettol to
enter the bateria’s system.

Plasma Membrane

The plasma membrane regulates the movement of substances moving into and out of the cell,
maintaining the cell structure, holding proteins and linking together tissues and cellular components.
The cellular components provide hydrophilic signals, a molecule that has a better reaction with water
and other polar substances, than the reaction with oil or other solvents. The membrane contains
proteins which transport protein makers and salt in and out, which help other proteins attach and act
as a identifier for the bacteria. This helps the membrane communicate with each other.

Cytoplasm

Cytoplasm is made up of mostly water and salt. It is present beneath the plasma membrane and is a
jelly like fluid.

The cytoplasm holds enzymes, this part of the bacteria is also responsible for breaking down waste
and aiding in metabolic activity (The life sustaining chemical transformation within cells)

Cytoplasm helps form the shape of the bacteria, it fills the inside with a jelly like fluid making the
bacteria have a more solid form.

Ribosome

The ribosome function is as a form of workbench, it it translates the genetic instructions for the
formation of specific proteins, they are the cellular component that makes proteins from amino acids.
Ribosomes are made up of RNA, ribonucleic acid, RNA is a molecule essential in coding, decoding,
regulation and expression of genes. RNA is almost identical to DNA, but RNA is made of ribose sugar
instead of deoxyribose sugar and have nucleotides with a uracil base instead of thymine.

Plasmid

Plasmid is a small DNA molecule within the cell that is physically separated from the bacterial DNA,
this can be replicated independently. When a bacteria is under stress, the plasmid helps keep them
alive longer, this gives the bacteria a better opportunity to reproduce and pass the plasmid onto their
daughter cells.

The form of plasmid is usually as a small, circular, double stranded DNA molecule, the genes carried
by plasmid provide bacteria with genetic advantages, such as a resistance to antibiotics.

Pili

The pili are like small hairs, they enable some pathogens to attach and adhere (Stick fast) easily to
cell surface. The pili are shorter, straighter and more numerous than the flagella and are composed by
subunits of protein.

The main function of the pili is to attach the bacteria to surfaces and other cells. The pill also aid in the
attachment between bacteria.

Flagellum

The flagellum is a long hair like surface. It allows the bacteria to move and will span from 0.1 to 50
micrometers in diameters, averaging to around 2 micrometers.

It is seen in three types of organisms, bacteria, archaea, and eukarya, yypes of single cell organisms.

The flagellum are used for locomotion, the three types of organisms have different flagellar structures.

Many different types of bacteria have flagella, consisting of: Monotrichous, Amphitrichous and
Peritrichous.

The flagellum has three parts, the filament, the hook and the basal body. The filament is a rigid helical
structure.

The hook is a flexible coupling, residing between the filament and basal body.

The basal body consists of a rod, a series of rings, these rings provide as an anchor for the flagellum
to the cell wall.

Binary Fission

Bacterial reproduction

Binary fission, division in half, is an asexul process. It is the most common form of reproduction,
occurring in a variety of organisms, such as bacteria.

During the process DNA and segregation occur simultaneously. The parent cell splits into two halves.
First it replicates its DNA, elongates, splits and produces two equal daughter cells.

These cells are genetically identical, there are few occurrences of identical in daughter cells, this
occurs because of mutations present during binary fission.

Binary fission takes around 20 minutes to complete. Accurate timing for each step would be almost
impossible due to bacteria taking random times for each step, approximately adding up to around
20 minutes.

Diffusion

Diffusion within bacteria works with bacterial transportation systems.The bacteria transport systems are
operated by proteins, more specifically transport proteins, these proteins reside within the plasma
membrane, these proteins and plasma membrane act as a sponge, taking in nutrients in large numbers
to keep the bacteria energized and healthy.

Solutes (a minor component of a solution) are what bacteria use for nutrients, these solutes are
transported through the membrane by the transport systems, the transport systems have three ways to
transport the nutrients through.

The first is Uniport, uniport is where one solute will go through the the membrane in a straight/non-indirect
line.

The second process is Symport, symport is where two solutes are transported at the same time through
the membrane in the same direction.

The last process is Antiport, antiport is where two solutes are being transported at the same time, one
solute is transported into the bacteria, while the other is transported out, simultaneously.

The solutes consist of carbons, such as sugars, fats, and amino acids. The plasma membrane lets these solutes in, but the enzymes are what breaks down the complex compounds to use the nutrients.

	Plate 1	Plate 2	Plate 3	Plate 4		Average
Full Strength	30 mm	25 mm	30 mm	30 mm		31.67
Manufactures Instructions	25 mm	10 mm	30 mm	30 mm		18.33
Diluted	0 mm	10 mm	25 mm	25 mm		10.32
Water	0 mm	0 mm	0 mm	0 mm		0
Plate 4 is an unbelievable results. Full strength dettol would kill more than the manufacturer's instructions. I am ruling this plate out as untrue. The reasons it could have been messed up is because of the tweezers used, the examiners mostlikely didn't rinse the tweezers before taking a sample of the manufacturers instructions and therefore left the disk with pure dettol on it. This can cause more bacteria to die and result in a larger clear zone, as seen in the results.

As seen in the trend the disinfectant strength increased the clear zone, as I wanted to investigate the different strength of the dettol killed off at different rates micro-organisms, the higher concentration of dettol proved to be effect in this, but because of bacteria being set to die as soon as the dettol sets in it would be a waste to use a higher concentration of dettol on a larger surface.

Evaluation

During this investigation I found that the stronger the dettol was the larger the clear zone would be.
But, if I were to use undiluted dettol on a tile floor it would be a waste of dettol, the moment dettol
seeps into the bacterias system the bacteria is set to die, using the diluted dettol will kill off bacteria
effectively and will not waste any dettol.

This investigation was fair due to having five different results, four with similar results and one with an
odd result, this result was left out of the graph. All instructions were followed correctly to get the best
results in the experiment giving a more accurate result. Our results were off due to the agar plate not
being placed in the incubation chamber straight away, this proved difficult for my results but due to
having other results to work with I could work out the information needed.

This is my results, as you can see the bacteria did not grow properly to get the information needed to
calculate my results.

This is one of the more accurate result I used, as you can see the bacteria grew well and more
accurately when killed off. This provided good information to help calculate the information needed for
my results.

Here are the other results I used

Perfluorinated: a chemical that contains carbon-fluorine bonds. Used in teflon, water resistance textiles
and fire-fighting foam. This chemical is a Heteroatoms, a compound of 3 chemicals.  

Carboxylic: An organic compound of 3, O, R, and OH. It occurs widely within the body, the acid
includes amino acids, the acid that creates protein, usually occurring within blood and tissue.

Total Internal Reflection

Report Sheet 1 What is Internal Reflection?

Source 1) Write URL, book or magazine: https://www.britannica.com/science/total-internal-reflection

Information from Source 1) (copy and paste from website, book or magazine) Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle. In general, total internal reflection takes place at the boundary between two transparent media when a ray of light in a medium of higher index of refraction approaches the other medium at an angle of incidence greater than the critical angle. For a water-air surface the critical angle is 48.5°. Because indices of refraction depend on wavelength, the critical angle (and hence the angle of total internal reflection) will vary slightly with wavelength and, therefore, with colour. At all angles less than the critical angle, both refraction and reflection occur in varying proportions.

Key words from Source 1 Total internal reflection, medium, water, glass, surrounding surfaces, angle of incidence, critical angle, two transparent media, higher index of refraction, wavelength, varying proportions.

In your own words summarise relevant information from website, book or magazine Total internal reflection occurs when the angle of incidence is greater than the critical angle. Total internal reflection takes place at the boundary of two transparent media’ when the incidence ray shines through the medium with an angle of incidence greater than the critical angle. Different surfaces change the critical angle, and because indices of refraction depend on wavelength the critical angle will change size slightly.

Report Sheet 2 How internal reflection is used in everyday life?

Source 1) Write URL, book or magazine: https://www.quora.com/Why-does-a-mirage-happen-in-the-desert http://www.planet-science.com/categories/under-11s/our-world/2012/01/what-is-a-mirage.aspx http://www.physicsclassroom.com/class/refrn/Lesson-4/Mirages http://laser.physics.sunysb.edu/~wise/wise187/2001/reports/andrea/report.html http://www.hk-phy.org/iq/mirage/mirage_e.html

Information from Source 1) (copy and paste from website, book or magazine) It is due to the phenomena of 'total internal reflection'. On a very hot day in a desert, the air just in contact with sand is hotter than the air above it due to the high temperature of sand. This causes the refractive index of the air in contact with the sand to be lower than that of the air above it. Thus, sunlight passes through a medium of higher refractive index to that of lower refractive index. At a particular angle, the angle of incidence becomes greater than the critical angle and all the conditions of total internal reflections are fulfilled. This causes the sunlight to reflect from the interface of both the air columns itself without touching the sand. Hence, it appears as a watery surface from far off distances, also known as mirage. While going nearer to the apparent water, the angle of incidence of sunlight decreases and becomes less than the critical angle. So, total internal reflection does not occur for that point at that angle and hence the mirage disappears. Mirage is thus visible only when the distance from a point is greater than a critical distance determined by the refractive index of the air columns to satisfy the condition of critical angle for total internal reflection to occur. When light passes from one medium into a second, less dense medium, the light bends away from the normal. At a particular incident angle, the angle of refraction will be 90 degrees, and the refracted ray would travel along the boundary between the two media. Source 2 The incident angle at which this occurs is called the critical angle. This angle can be calculated by using Snell's Law: sin(critical angle) = (n2/n1)(sin 90 degrees) = (n2/n1) Where n1 = index of refraction in 1st medium n2 = index of refraction in 2nd medium If the angle of incidence is increased beyond the critical angle, the light rays will be totally reflected back into the incident medium. This effect is called total internal reflection. But note that total internal reflection cannot occur if light is traveling from a less dense medium to a denser one. Source 3 Most of our discussion of refraction in this unit has pertained to the refraction of light at a distinct boundary. As light is transmitted across the boundary from one material to another, there is a change in speed, which causes a change in direction of the light wave. The boundaries that we have been focusing on have been distinct interfaces between two recognizably different materials. The boundary between the glass of a fish tank and the surrounding air or the boundary between the water in a pool and the surrounding air are examples of distinct interfaces between two recognizably different materials. It has been mentioned in our discussion that the refraction or bending of light occurs at the boundary between two materials; and once a light wave has crossed the boundary it travels in a straight line. The discussion has presumed that the medium is a uniform medium. A uniform medium is a medium whose optical density is everywhere the same within the medium. A uniform medium is the same everywhere from its top boundary to its bottom boundary and from its left boundary to its right boundary. But not every medium is a uniform medium, and the fact that air can sometimes form a non-uniform medium leads to an interesting refraction phenomenon - the formation of mirages. Refraction in a Non-Uniform Medium A mirage is an optical phenomenon that creates the illusion of water and results from the refraction of light through a non-uniform medium. Mirages are most commonly observed on sunny days when driving down a roadway. As you drive down the roadway, there appears to be a puddle of water on the road several yards (maybe one-hundred yards) in front of the car. Of course, when you arrive at the perceived location of the puddle, you recognize that the puddle is not there. Instead, the puddle of water appears to be another one-hundred yards in front of you. You could carefully match the perceived location of the water to a roadside object; but when you arrive at that object, the puddle of water is still not on the roadway. The appearance of the water is simply an illusion. Mirages occur on sunny days. The role of the sun is to heat the roadway to high temperatures. This heated roadway in turn heats the surrounding air, keeping the air just above the roadway at higher temperatures than that day's average air temperature. Hot air tends to be less optically dense than cooler air. As such, a non-uniform medium has been created by the heating of the roadway and the air just above it. While light will travel in a straight line through a uniform medium, it will refract when traveling through a non-uniform medium. If a driver looks down at the roadway at a very low angle (that is, at a position nearly one hundred yards away), light from objects above the roadway will follow a curved path to the driver's eye as shown in the diagram below. Light that is traveling downward into this less optically dense air begins to speed up. Though there isn't a distinct boundary between two media, there is a change in speed of a light wave. As expected, a change in speed is accompanied by a change in direction. If there were a distinct boundary between two media, then there would be a bending of this light ray away from the normal. For this light ray to bend away from the normal (towards the boundary), the ray would begin to bend more parallel to the roadway and then bend upwards towards the cooler air. As such, a person in a car sighting downward at the roadway will see an object located above the roadway. Source 4 Imagine you're in the desert. You're lost. You've been walking for hours. You've run out of water. On the horizon, you see a giant, shimmering puddle of water. "Yippeeeeeeeeee", you shout. You're saved! But...it's not a puddle of water. It's a mirage. Mirages are optical illusions that have fooled many thirsty explorers. Take a look at this video: How do mirages form? Normally, light waves from the sun travel straight through the atmosphere to your eye. But, light travels at different speeds through hot air and cold air. Mirages happen when the ground is very hot and the air is cool. The hot ground warms a layer of air just above the ground. When the light moves through the cold air and into the layer of hot air it is refracted (bent). A layer of very warm air near the ground refracts the light from the sky nearly into a U-shaped bend. Our brain thinks the light has travelled in a straight line. Our brain doesn't see the image as bent light from the sky. Instead, our brain thinks the light must have come from something on the ground. You can even see mirages in the UK. Have you ever seen a wet looking shimmer above tarmac on a hot day? That's the beginning of a mirage.

Key words from Sources Mirage, Optical, air heat, angle of incidence, critical angle, light rays, light waves, sun, atmosphere, eye, speed, hot air, sand, refraction of light, optical density, hot air, cold air, refracted.

In your own words summarise relevant information from website, book or magazine Mirages occur when the light rays of the sun are bent, due to the ground being hot and the air being cold, when the ground is hot it warms the air above it, this causes it to be denser and refracts the light rays, this happens because of optical density, giving it a high index of refraction, it slows the light ray down allowing it to bend and create the optical illusion. Our brain doesn’t see the light rays as bent, so it projects the image of water to try and fix the light rays we see. This happens because of the critical angle, at a certain distance, the light rays reach your eyes, but if you are to move closer, it disappears because the critical angle no longer exists at that point.

Total internal reflection occurs when the angle of incidence is greater than the critical angle. Total internal reflection takes place at the boundary of two transparent media, when the incidence ray shines through the medium with an angle of incidence greater than the critical angle. Different surfaces change the critical angle, and because indices of refraction depend on wavelength the critical angle will change size slightly.

These two phenomenons occur because if total internal refraction.
Mirages occur when the light rays of the sun are bent, due to the ground being hot and the aire being cold, when the ground is hot it warms the air above it, this causes it to be denser and refracts the light rays, this happens because of optical density, giving it a high index of refraction, it slows the light ray down allowing it to bend and create the optical illusion. Our brain doesn't see the light rays as bent, so it projects the image of water to try and fix the light rays we see. This happens because of the critical angle, at a certain distance, the light rays reach your eyes, but if you are to move closer, it disappears because the critical angle no longer exists at that point.

Unlike mirages, diamonds have a different effect with the different angles.
Because diamonds have a high refractive index, total internal refraction or reflection can occur, this occurs because of the position of the incidence ray/angle. If the diamond is strategically cut, it is able to have total internal refraction or reflection. The angle of incidence is moved and the reflected ray will bounce out the top, IF it is strategically cut. If it isn't strategically cut it will refract AND reflect into different angles, this is because the critical angle is acting here.

Task C:

Total internal reflection is seen all the time in everyday life, this phenomenon is changed using
mediums, the density of the medium, if the medium has a high refractive index, like plastic, it will
slow a beam of light and cause it to turn slightly, as soon as it leaves this medium, it will turn the
other way slightly again. If the medium has a low refractive index, like air, it will not change the
speed of the beam and it will continue forward.  

Mirages and diamonds are created and use this in everyday life.

Mirages occur when the light rays of the sun are bent, due to the ground being hot and the air
being cold, when the ground is hot it warms the air above it, this causes it to be denser and
refracts the light rays, this happens because of optical density, giving it a high index of refraction,
it slows the light ray down allowing it to bend and create the optical illusion. Our brain doesn’t see
the light rays as bent, so it projects the image of water to try and fix the light rays we see. This
happens because of the critical angle, at a certain distance, the light rays reach your eyes, but if
you are to move closer, it disappears because the critical angle no longer exists at that point.

Unlike mirages, diamonds use their own medium, not heated air.

Because diamonds have a high refractive index, total internal refraction or reflection can occur,
this occurs because of the position of the incidence ray/angle. If the diamond is strategically cut, it
is able to have total internal refraction or reflection. The angle of incidence is moved and the
reflected ray will bounce out the top, IF it is strategically cut. If it isn't strategically cut it will refract
AND reflect into different angles, this is because the critical angle is acting here.

The advantages and disadvantages of internal reflection.

Advantages of internal reflection include, being able to zoom in with a camera due to the light
bending, but this also can be a disadvantage because the signal then becomes low. Internal
reflection is something we use everyday, using it in optical fibers to send large amounts of
information long distances using glass or mirrors to reflect it. This helps us get information around
more effentically and quickly. This is also done in an endoscope, using a medium to redirect the
light so the user can see inside the interior of organ and cavities within the body, this can help a
patient survive possible illnesses.

Using this can also cause things to come out as different, or wrong all together, because of optical
illusion like a mirage, our brain may not register it as correct and it will try replacing whatever is
missing or seems wrong with something that seems more logical.

Art history analysis

Analysis 1

Edward Hopper - Woman in the sun - 1961 - Analysis

• • 
    

  • The grey tones of the room really helps to attract the eye to the woman and the sunlight, and maybe the window. Being able to see most of the brush strokes helps give it a sense of realism, being able to see the walls looking a bit fuzzy makes it seem like it’s old, as does the faded colours on the wall. The room itself looks old, but the woman and bed look new. The woman doesn’t look happy, maybe she wanted a better lifestyle, or maybe she was lonely? She could be using smoking to distract herself from these thoughts. The room itself isn’t very full, she could be lacking funds to get things like draws or mirrors, or even freshen up the place and make it look ‘new’.

  • The woman seems deep in thought, she could be thinking anything, like ending it all, or maybe what she’ll have to do at work. She also could of had a good time before and only just got up and thinking about that.

  • I noticed the woman hasn’t lit her cigarette, perhaps she forgot to do this while lost in thought, she may have wandered the room without noticing before deciding to stop and look out the window, she may never notice it isn’t lit, but that is all up to the viewer to decide whether she finally comes back to reality and lights it or not.

  • Edward used the light of the sun to guide you to the woman, like a path with an end.
    The way he painted the apartment helps give four factors, the room, the woman, the empty alcove by the window, and the hills, clouds and sky outside. The colours all blend in well together, giving the room the nice old feel, the outside a nice new growing feel and the sun a beautiful glow to enlighten the ground and woman, the shadows allowing you to see her muscle tones and part of her ribs, which make her look a bit malnutritioned.

  • The size of the painting is Overall: 40 1/8 × 60 3/16 in. (101.9 × 152.9 cm) which isn’t one of his biggest pieces of art, but it still looks like a window into someone's life, it doesn’t feel like you are in the room itself, but it does feel like you are looking through a window and watching her, but she can not see you. All though many of his other paintings give this a better feel, it is still a odd feeling to be watching the woman.

Analysis 2

Edvard Munch - Separation

• The way the dim colours are put together helps give it the feeling of sorrow or mourning. Maybe the golden lady is someone the man recently divorced, or maybe they died and the man doesn’t know how to deal with it, the less dim hand of the man is like he is holding the last thing he has that he cares for, maybe that’s why it is placed on his chest around where the heart it, maybe it is his heart being broken and he is trying to keep it together.

• His clothing choice looks sort of like pyjamas, perhaps this happened a while ago and he is finding a way to deal with it, or trying to remember everything before it’s too late.

• The tree behind him could signify death, it isn’t growing any leaves. It could also be what the man is going to use it to get back with his lover or family member.

• The dark clouds, or maybe they are leaves, could signify a stormy day, which is known in cartoons as gloomy or angry, but his facial features show that he is gloomy, or sad.

• The way the golden woman is walking, or floating, makes it look as if she has created a path or following one to her destination, this destination could be heaven or hell, or her/his final resting place, they are also not paying any attention to the man, maybe this is just the way he sees her and she is breaking up with him and moving on, while he can’t.

• The way the woman and hand are coloured helps draw the viewers eyes to them first, allowing people to try and decipher what is going through their minds.

• The women having no face is possibly done on purpose, to make it seem as if she doesn't need to worry for those emotions anymore, she can just continue her life brightening the sky with her golden strands, of presumably hair. As you can see yourself the hair is kind of like sun shining through, this could signify hope, giving maybe the man another chance..

• Unlike the ‘Woman in the sun’ painting by Edward Hopper, you can not see the muscles very well. They style is very simplistic but it still has a lot of depth in it.

What, How, Why - Art - Feb 23 - 2018

#whathowwhy

So, in Art we are doing a portfolio. We have done brainstorms of what we care about and I choose Mental Health and Disabilities, I choose this subject because I like the idea of people hallucinating, or the way people see things in their view, I find it interesting the way a young child will see things and then how an adult sees it. There is also the fact that I can take the concepts of horror for hallucinations and see how our imagination can be used against us because of paranoia and fear which can lead to many different mental health issues.
For disabilities, I just hate how people can just leave people out because they want to do something instead, I prefer to miss out and keep the other company and watch with them, or do something together. So for this one I want to show how those with disabilities need more help, and that they are still human.

My theme is: Mental health and disabilities  

Choose 3 IDEAS which are covered by your THEME
(e.g. global warming, water pollution and overpopulation)

Idea 1: Person hitting a dead end, doing multiple (or one) thing/s (Self harm, homeless, cold, raining, crying, hiding from the world or running from problems)
Idea 2:  Hospital area (No help, running, hiding, struggling, escaping, locked away)
Idea 3: Access ability

SUBJECT MATTER is what you see in an artwork e.g. the subject matter in ‘The Mona Lisa’ is a woman. For each of your IDEAS, choose 3 things that you could use as SUBJECT MATTER that fit the idea
(e.g. wilted plant, polar bear in a desert, weather map)

Idea 1 could have these things as subject matter:

1. Dark smokey ghost like beings laughing at someone or something
2. Being chased by real people, maybe some changing to be fake hallucinations
3. Hiding from problems, which can take form as something they fear, or seek comfort from, having multiple things or people talking to them.

Idea 2 could have these things as subject matter:

1. Experimented on? (Changing slowly without knowing? Or knowing but trying to resist, fear?)
2. Apocalyptic or demonic/ghost based theme (Hallucinations of fears, or using this as a way of showing how they think of the things in the hospital) happening in the room or hallways, or looking through/out of windows
3. Insane hospital effect (Possible hallucinations, fearing that they may be crazy and that they’re apart of an insane asylum)

Using fear against the person to show maybe a child's perspective of how they see adult jobs, or maybe their parents in an operation, or seeing their parents as a monster for ‘killing’ someone with a failed operation, or because it was a disease that no one had a cure for yet.

Idea 3 could have these things as subject matter:

1. Someone in a wheelchair in front of a building with stairs
2. Someone not being able to get out of a room or unable to move to another spot, or unable to join in with a game
3. Sitting out of many things, being bullied because they’re different

I think I'm going to work more on the ideas of 2 or 1, using sketching and painting as my two main mediums.

I may be using things like a empty wheelchair to signify someone having recovered, or maybe add a ghostly figure to show that someone never recovered or the past.

Possibly a mark on a wall to signify pain or struggle, maybe a chain to also signify struggle.
I could use a form of internet, maybe use facebook or twitter and put two things side by side and see what others prefer (Maybe a disabled person (Or someone who suffers from mental health) and the other someone that is classed as 'handsome' doing the same pose)

PBL Checkpoint 11

Checkpoint 11

We choose water safety as our topic. We went to Hornby Primary school and run activities, these activities were Relays, Capture the flag, Atomic Whirlpool, Water Relays, Find the Golf balls. I feel it was successful, the kids there enjoyed these activities, they had fun and learned new things. They kids seemed to know a good amount about safety when we asked them questions, they were able to answer our five questions confidently.

I feel we achieved our goal in teaching these kids about water safety, they listened well and did what they needed to for each activity without complaint.

The thing I feel I helped most with was talking about the problems that may come when teaching these kids, saying things that may help and trying to think of better ways of doing something in an activity. I am pretty sure the kids were comfortable around me, they were able to talk freely and ask for help if needed, I cheered them on during their activities which I feel helped them try and do their best.

I would probably add more activities for the pool that can give a better learning experience and have a proper number of students joining us. I would also figure out a better time schedule so we aren't behind or ahead of schedule, with more activities it would be better for time.
