Title: The Walking Dead
Developer: Frank Darabont
Text Type: TV Series
Date Finished: 7/7/17

Summary:
The TV series The Walking Dead developed by Frank Darabont is based on the comic book series written by Robert Kirkman. The Walking Dead portrays life weeks, months and eventually years following a zombie apocalypse. The main character and leader, former police officer Rick Grimes, his family and a group of other survivors find themselves constantly on the move through out the seven seasons, looking for a safe and secure home. But Rick soon realises that the world they are now living in has changed. He discovers that the staggering fear of the survivors can be more deadly than the zombies walking among them. ''Fight the dead, fear the living''

Personal Response:
Statement - A character I related to was Carol
Example - For example, in the first and second seasons Carol was a weak, helpless, old lady who couldn't protect herself or anyone else. However, from the third season on wards, Carol adapts to the new world and gets stronger and more ruthless.
Explanation - Losing her daughter to a viscous zombie attack in season two really made her a lot more hard, heartless and aggressive which was needed to survive in the new world that the're living in. I have adapted to new things before in the past. I personally think that I would be able to change and adapt enough to survive a zombie apocalypse like Carol did.
Your Link - I think this relates to the real world because there are plenty of real life scenarios where normal people have to change themselves and there lives due to a certain situation.

Personal Response:
Statement - An important lesson to learn from this TV series is to never stop fighting and to never give up.
Example - For example, in season seven where Negan - a bad guy with a massive army - kills two of the survivors and captures one, as well as taking all there stuff and making them work for him.
Explanation - During the last few episodes of season seven, Rick and the few survivors remaining come up with a genius plan to fight back and kill Negan and his army. However after there plan gets over powered by the amount of people Negan has on his side, Negan decides to kill Ricks son Carl right in front of him before the people of Alexandra and The Hill Top - two committees that were thought to be weak and useless - saved the day by shooting down almost all of Negans army. Together they kept fighting and fighting until every last one of them had either ran away or died.
Your Link - I think this TV series relates to some of the people in the real world who might have a really hard life but they never give up and they don't stop fighting until they get what they want.

Rates of Reaction

Experiment 1              Investigating the Effect of Temperature on Reaction Rate

Aim:
I want to investigate how temperature effects the reaction rate.

Equipment:
A conical flask, beaker, measuring cylinder, stopwatch, black cross on paper, water bath, thermometer, 0.l mol L-1 hydrochloric acid (HCl).

Method:
1. Put the 'X' paper on the bench mat, and put the conical flask on top of the paper.
2. Measure 50 mL of sodium thiosulfate solution and put it into the beaker.
3. Record the temperature of the sodium thiosulfate.
4. Measure 5 mL of HCl and pour this into the conical flask.
5. Pour the sodium thiosulfate into the conical flask, start the stopwatch and swirl the flask. Time how long it takes for the cross to disapear when viewed from above (i.e. look down the mouth of the conical flask)
6. Wash out the flask thoroughly.
7. Repeat the experiment, using a water bath to heat the sodium thiosulfate to 30 degrees, then 40 degrees and finally 50 degrees. Keep the volume of acid the same each time.

Results:
Non Heated
sodium thiosulfate - 12 degrees
HCl - 31.41 seconds

Heated(30 degrees)
sodium thiosulfate - 30 degrees
HCl - 9.60 seconds

Heated(40 degrees)
sodium thiosulfate - 40 degrees
HCl - 13.10 seconds

Heated(50 degrees)
sodium thiosulfate - 50 degrees
HCl - 3.46 seconds


Experiment 2                  Investigating the Effect of Concentration on Reaction Rate

Aim:
I want to investigate how concentration effects the reaction rate.

Equipment:
A conical flask, measuring cylinder, stopwatch, black cross on paper, 0.2 mol L-1 sodium thiosulfate, 1.0 mol L-1 hydrochloric acid.

Method:
1. Put the 'X' paper on the bench mat, and put the conical flask on top of the paper.
2. Measure 10 mL of sodium thiosulfate solution and put it into the conical flask.
3. Measure 40 mL of water and put it into the conical flask. Swirl the flask to mix the contents.
4. Measure 5 mL of acid. Pour the acid into the flask, start the stopwatch, and swirl the flask. Time how long it takes for the cross to disappear.
5. Wash out the flask throughly. Repeat the experiment using the other volumes of the sodium thiosulfate and water in the table on the right. Keep the volume of acid the same each time.

Results:
10 mL of sodium thiosulfate/40 mL of water
4 minutes, 43 seconds
20 mL of sodium thiosulfate/30 mL of water
2 minutes
30 mL of sodium thiosulfate/20 mL of water
54.63 seconds
40 mL sodium thiosulfate/10 mL of water
44.22 seconds
50 mLof sodium thiosulfate/0 mL of water
33.62 seconds


Experiment 3                  Observing the Effect of Surface Area on Reaction Rate

Aim:
I want to observe the effects of surface area on reaction rate.

Equipment:
boiling tube, calcium carbonate chips and powder, hydrochloric acid, measuring cylinder, spatula

Method:
1. Measuring 2 mL of hydrochloric acid and pour this into your boiling tube.
2. Holding your boiling tube over a sink or heatproof mat, add a pea-sized amount of calcium carbonate powder to your boiling tube.
3. Repeat the experiment, but this time use a chip of calcium carbonate that is roughly the same size as the spatula of power you used previously.

Observations:
When I added the powder, it fizzed up.
When I used chips, it bubbled up.


Experiment 4                        Catalysts

Aim:
I want to observe the effects of a copper catalysts on the reaction between zinc and sulfuric acid.

Method:
1. Add roughly the same mass of zinc to test tubes 1 and 3
2. Add roughly the same mass of copper to test tubes 2 and 3
3. Add 5 mL of dilute sulfuric acid to test tube 1
4. Add 5 mL of acid to test tube 2
5. Add 5 mL of acid to test tube 3

Observations:
Test tube 1 - it fizzed up
Test tube 2 - it bubbled up
Test tube 3 - nothing much happened

Analysing Interpersonal Skills

1. The coach in video one was too loud almost all of the time and had poor body language. Also had nothing but negative things to say to the kids. The coach in video two was much better. He had the right tone of voice, good body language and positive things to say.

2. The coach in video one was not very successful because the kids were not taking getting yelled at to well. It distracted them from the game. The coach in video two was pretty successful. The kids were involved, happy and having fun because of  the good coaching techniques the the coach in video two applied.

3. The coach in video two was more successful.

Title: The Maze Runner
Author: James Dashner
Text Type: Novel
Date Finished: 24 March 2017

Summary:
The book The Maze Runner written by James Dashner is about a teenager called Thomas. He wakes up in a glade surrounded by an enormous, monster infested maze. Just like the other teenage boys that were put there before him, he has no memory of his past life. Thomas quickly becomes a runner - someone who runs the always changing maze. With the help of Teresa - the only female, he tries to convince his group that he has found a way out.

Personal Response: SEXY Paragraph 1
Statement - A character I related to was Thomas.
Example - For example, the part when Thomas first arrives in the glade and he sees the giant maze he is instantly curious as to how he got there, who put him there and what was in the maze itself.
Explanation - If it was me I would also be very curious as to what was going on and I would want to find out what was going on even if that means breaking the rules a little bit like Thomas did.
Your Link - I think that this book relates to real life because it shows that people will naturally follow other people if they have a good leader. I believe that this is because most people lack the self of steam to be there own leader so they feel more safe and more comfortable letting someone else take control.

Personal Response: SEXY Paragraph 2
Statement - An important lesson to learn from this book is to not waste your life living in fear, sacrifice your life to live in freedom.
Example - For example, the part after Thomas convinces most of his group to come and fight for there chance of freedom, they all face a terrifying greaver - massive monster - that ends up killing some of them.
Explanation - But they keep on fighting together and they win there right for freedom by destroying the greaver.
Your Link - I think that this book relates to the fighting spirit that humans have in real life.

Title: The Hunger Games
Director: Suzanne Collins
Text Type: Novel
Date Finished: 13/4/17

Summary:
The book The Hunger Games written by Suzanne Collins is about a nationally televised event called The Hunger Games. The Capital of Panem has 12 districts. Each year each district picks a boy and a girl to fight against each other and the other boys and girls from the other districts until only one remains. District 12 tribute Katniss Everdeen has little to rely on, other than her hunting skills and sharp instincts. She is in a arena were she must choose between survival and love.

Personal Response: SEXY Paragraph 1
Statement - A character that I related to was Katniss Everdeen
Example - For example, the part where Katniss volunteers as tribute for her little sister Prim after Prim gets chosen to be in the Hunger games.
Explanation - If it was my younger sister getting chosen to fight in The Hunger Games then I would volunteer as tribute so it would be me possibly dying instead of her.
Your Link - I think that this book relates to the real life family orientated people that would sacrifice themselves for a beloved family member.

Personal Response: SEXY Paragraph 2
Statement - I felt sorry for all the boys and girls who had to compete in the Hunger Games.
Example - For example, the part where it said that this little girl Rue was competing.
Explanation - I instantly felt sorry for her because it was obvious she was going to get killed.
Your Link - I think that this book shows the bad in some people. Like when President Snow created The Hunger Games and forced a poor boy and girl from each district to fight one another to the death. It shows that he only cares about his people(rich people).
