Title: Remember the Titans
Text type: Film
Director: Boaz Yakin
Remember the titans is a film based in the 1970s - 1980s, remember the titans is a film about a high school football team which have just turned into an interracial school. This team decide to go to on a tournament together but as you'll know, it doesn't end very well. The boys split themselves up, into the whites and the blacks. The boys fought with each other and made racist jokes towards each other. But There coach had enough of it and he then decided that if he was to put 2 whites onto a room and 2 blacks into that same room that they could bond together and not hate each other forever.
I can really relate to this movie because this is all i see sometimes. People making racist remarks towards each other. It's aloe better than what it used to be as of the 21st century but in the 20th century whites looked at the blacks as poor and useless. I hate people being racist because in my opinion we are all same on the inside. And we all are the same in general. It was just that 1 difference of skin color that made. For example when they learn that each other are the same Sheryl says this "people say it can't work, black and white, well here we make it work, everyday. We have our disagreements of course but before we reach for hate, always remember we are the titans." This can be seen in 12 years a slave because the exact same thing happens with all the racial abuse and fighting as well as the negativity towards the colored
Today one of the most racist remarks that i always here is about Asians, people make rude remarks by the way they drive and the way they look. But what some people don't realise is that if they were to go to their country they would feel the exact same way as they do. I believe that this relates back to the movie because back then the whites thought of the blacks the exact same way. They thought they were useless and stupid and that they didn't know how to do anything. In the movie 12 years a slave the white owners believed that the only thing they were good for was to make them money. This racial abusiveness is still going around this world to this day. every culture these days have a racist remark towards some kind on country

Title: The complexion of fear
Text type: Article
Writer: Mary .C. Lamia
Are you experiencing anxiety or fear?, In this article the writer talks about the things you imagine and he things the you feel. She also talks about what the difference between anxiety and fear is, and is there a difference?
This article uses the ways of someone jumping out of a bush at you. It then says is the feeling you get from this when your heart races, is it anxiety or is it the fear. Lamia explains the things you would do in that moment. Would you fight which is when you would fight for your own ground and for your own good, or would you freeze which is when you just pretty much stay still and not move. Would you get a fright, which is when you just get a major fright from all the stress and things you are feeling. Lamia also says that response for most people is to turn to others for help so that that you can feel less tense or even in less danger than you already were in the situation. She also explains the anxiety is a general place of stress that is longer lasting. It is also found ti be triggered by something that is non specific in any way. Which means it can happen through nervous nous or apprehension.
I found a way in which that i could understand this text quite easily. Due to the fact that i can related to it a bit and its things that my family and friends suffer from. I have already grown with the experiences of fear and anxiety because its normal to me. This text is shown me ways of peoples reaction to fear and how to prevent it. There was a way in which this text also had shown that sometimes there is no way of avoiding fear and anxiety. I have always been afraid of heights. When i'm high in the air all i think about is today going to be the day where i fall to my death. I was able to stop this fear by attempting to ab sail. Once i did it once the fear was no longer there and i just wanted to continue doing it. My reaction was to fight it. I stood there and ab sailed which meant i took on what i was afraid to do. There was a way where i could have avoided it but i took all the fear and anxiety and turned it into an amazing experience

Title: Life after sport
Text type: Article
Written by Emma Vickers
Life after sport is a article which was written about what happens to famous sports stars and Olympic medalists after they have retired. Its about the death rate that occurs from retirement due to having no qualifications to get a job and talking about who you actually are once you become a retired athlete.
Elite athletes train excessively for many years non stop and in many cases it consumes their lives. In my opinion this shouldn't be the case for athletes. This article showed me that even the most paid athletes end up going in some sort of depression due to not being able to stick with something they love. Its hard for them to find a job to get money in due to having no qualifications. For some athletes its different, some believe its better due to them being able to not have the stress of staying on top or competing. Loss of identity occurs sometimes too due to them not feeling loved or acknowledges for their sporting anymore. "Tunnel vision syndrome" its when an athletes is so focused on winning that they don't focus on career opportunities. Athletes should be given some chance to adjust themselves to a basis of a new lifestyle.
Something that caught my eye was when the author wrote about a boxer called Sugar ray Leonard. He quoted "nothing could satisfy me outside the ring, there is nothing in life that compares to being a world champion with having your hand raised in that moment of glory. With having millions of people cheer you on" He suffers from sever depression due to him not being able to box anymore. For young adults becoming athletes i think that they should study before they go into their sporting world. or they could at least think ahead for once they retire in their sports. Another thing that annoyed me was that a famous athlete just missed out on succeeding in getting a gold. Since she didn't get this gold medal she fell into a severe depression and ended up taking her life. The older the person is than the easier it is for them to fall into a depression once they retire.

Bacteria and Disinfectants
Research
Purpose: How the concentration can effect the rate in killing bacteria
What is Bacteria: Bacteria is a micro-organism. Bacteria is known to be one of the first life forms on earth and in the soil
What is the life process if bacteria? MRS GREN - Movement, Reproduction, Sensitivity, Growth, Respiration, Excretion and Nutrition
How does disinfectant work? Disinfectants kill bacteria extremely fast when they come into contact It works on living things a swell as non living things
What is savlon? Savlon is an antiseptic that is used to kill bacteria, you can put savlon on cuts to clean the injury from any bacteria
What is the active ingredient in savlon? It is called cetrimide. It is a mixture of different kinds of ammonium salts. When it comes into contact with bacteria it disrupts the cell wall on the bacteria which stops the function of enzymes in the nucleoid. Savlon also kills bacteria within 15 seconds
Trial Experiment
Aim: I want to investigate how the concentration of dettol effects the growth and reproduction of bacteria
Hypothesis: I predict that the higher the concentration of dettol will create a large clear zone in the agar plate
Independent variable: Concentration of dettol, 1% 10% 100% and control (just water)
Method:
8. Put cello tape around the agar plate and wait for the bacteria to grow
9. Measure the clear zones on the agar plates
10. Repeat if needed
Discussion
What is disinfectant? Disinfectant is liquid the you can apply to the surface of non-living things and living things to kill good and bad bacteria rapidly when in contact. Antiseptic is used on skin, it is made so that it kills bacteria in cut but yet it won't hurt. There are wide ranges of substances which are used as disinfectant including alcohols. Disinfectant works in different ways, Hydrogen peroxide reacts to produce free oxygen radicals and bleaches. They are based on chlorine compounds which are very powerful oxidising agents. They oxidise the complete molecules which are present on the surface of bacteria, causing their cell membranes to disrupt. Proteins on the surface become damaged and they then start to stick together in clumps. Bacteria cannot respond to the damage quickly enough and the whole cell splits open and dies.
The structure of bacteria: Reproduction of bacteria:
Capsule - Protective outer layer
Cell wall - Structure to give shape and protect it aswell
Ribosomes - Build protein for the cell
Plasmid - Extra bits of DNA
Cell membrane - Nutrition and excretion (lets food in and lets waste out)
Pili - Bridge to other bacteria
Flagellum - Used for movement
Cytoplasm - The soup of the cell that holds the DNA, ribosomes, plasmids but it mostly holds water
Nucleoid - Holds DNA for essential life

Reproduction and Nutrition of bacteria:
Reproduction (binary fission)
During their asexual reproduction a single DNA replicates and both copies attach, at a different point on the bacteria. As the cells begin to get bigger and join the distance between the DNA molecules begin to increase. Once the bacteria doubles in size the cell membrane begins to pinch in the centre, Then a cell wall forms which ends up separating the two cells. That original cell is now two identical daughter cells.
Nutrition
Bacteria are autotrophs or heterotrophs but most are autotrophs, The autotrophs make their own food from outside sources of energy. Heterotrophs don't make their own food, they rely on readymade food from outside to be able to survive
Evaluation
The data I created wasn't as reliable as it should've been to use and measure. We ended up having 3 valid results although it could have been better. We almost had to redo our experiment due to using too much yogurt on the agar plates. We were able to fix this due to the fact that the bacteria did grow and left some clear zones. Which we were able to work with and measure the other clear zone that occurred. The other clear zones that didn't work to well we were able to estimate where the clear zone and draw a circles around it with the marker. We did this to make it easier to measure and easier to find the results

Hypothesis: I predict that the higher the concentration of dettol will create a large clear zone in the agar plate
Independent variable: Concentration of dettol, 1% 10% 100% and control (just water)
Dependent variable: The inside of the clear zone (mm)
Equipment:
- Agar plate
- Dettol
- Yogurt
- Filter paper
- Marker
- Ruler
- Ethanol
- Dropper
- Spotting tile
- Cotton bud
- Tweezers
- Cellotape
Method:
1. Get Equipment
2. Use the marker to divide the agar plate into 4 sections (on jelly side) In each section label the different concentrations of dettol
3. Get the cotton bud and smear the yogurt onto the jelly on the agar plate
4. (make sure dropper is always clean so there is no contamination) Using a dropper put a few drops of dettol into the spotting tile (100% concentration) Add 1 drop of dettol onto another spotting tile than add 9 drops of water (10% concentration) then take the 10% concentration and add some of that to 9 drops of water on the spotting tile (1% concentration)
5. Use a whole punch to punch 4 holes out of the filter paper (circles must be the same)
6. Dip ends of tweezers in ethanol and run it through the Bunsen burner to sterilize them
7. Using the tweezers now pick up the filter paper and dip each paper into a different concentration and then blot the filter paper do their is no excess concentration and put onto agar plate under the right label
8. Put cello-tape around the edges to close the agar plate and wait for the bacteria to grow
9. Leave overnight and measure clear zone.

Method:
1. Get your equipment.
2. Start by using a permanent marker (on the jelly side) to divide the agar plate into 4 sections. In each section label them with the different concentrations of Savlon. (eg. 100%, 10%, 1% and water)
3. Get a beaker and add the yogurt. Then put some water into the beaker to dilute it, which will make the yogurt more of a runnier texture. This will make it easier for you to just pour it onto the agar plate and move it around so the whole surface is covered, and you can get a clear look at the bacteria.
4. Using a dropper, put a few drops of Savlon into a spotting tile. This is the concentration of 100%, and again using the dropper put 1 drop of the Savlon into a separate tile. Then this time add 9 drops of water to equal a concentration of 10%. Repeat this step again by taking a drop of the 10% concentration, to then create a concentration of 1%. (Make sure the dropper is always clean so there is no contamination)
5. Then punch 4 full circles into the filter paper using a hole punch. (If the circles aren't the same the test won't be fair)
6. Dip tweezers in ethanol and then but through the Bunsen burner to sterilize them

Conclusion
Conclusion
The aim of this experiment was to investigate how different concentrations of savlon can effect the growth and reproduction of bacteria. I predicted that the larger the concentration of savlon there was that then the larger the clear zones were. After looking at my data i can see that there is an increasing trend. If you increase the concentration of bacteria then the larger the clear zone will be.
