Title: Coach Carter

Director: Thomas Carter

Text Type: Film
Initial Release: 13 January 2005

Coach Carter is a powerful film about a high school basketball team called the 'Richmond Oilers' the school is in a very low decile area where most high school students are getting themselves into bad situations. The Richmond Oilers get a new coach, called Ken carter. Ken carter originally was a student at Richmond who holds many basketball records. Ken carter became the coach so he could enrich the lives of these players so they could do something with their lives, but this all gets ruined when the players end up failing all their classes even though the oilers were undefeated in their new season. Which is when coach ken carter takes a stand and locks the players out of the gym until the players reach a 2.3 gpa. This then causes chaos in the Richmond community and Coach ken carter gets sent to court, but in this case he takes his first loss fot the team.

I thought that coach ken carter was the most inspirational character in the film. At the beginning of the film he was mean and selfish, as well as he was quite stubborn. But towards the end he becomes more and more caring, the reason he was doing it, was to get the best out of the team and get all of their full abilities to arise., now I realise that he's only coaching this team to make a change in young teenagers lives to keep these teenagers out of prison. When the team first meet the coach they had no respect for him. They were careless and furious towards him because they didnt understand what he's doing for them with tike and effort. They only cared about his skin colour and his knowledge of the sport. I think a lot of people can relate to coach ken carter because he's a man who's grown up in a bad community with bad experiences. So he's making a change to the world. There are a lot of people these days who can make simple differences in the world and  all they need to do is love eachother not hate eachother. This world is full of hate today, it doesn't matter what starts it but all that matters is how it ends and what it will destroy in its Path, coach carter is so inspirational, he shows that it doesn't matter what community or what race you are from, he shows that all that matters is the live that we give eachother. 

The theme of love is the best theme for this film. Because In the film coach ken carter put the team in situations where they had to work together to be able to to reach their goal, and along the way of reaching these goals the team became closer through every step. For example through out the film, the players drastically changed the way they looked after their coach after they realised all he was doing is keeping them out of trouble. This can be seen when coach carter says "I see a system that's designed for you to fail.. Richmond High only graduates fifty percent of its students. And of those that do graduate only six percent go to college; which tells me when I walk down these halls and I look in your classrooms, maybe only one student is going to go to college. Young men in Richmond  probably will go to prison. In this county, thirty three percent of black males between eighteen and twenty four, get arrested. So look at the guy on your left, now look at the guy on your right. One of you is going to get arrested. This film shows how easy it is for 1 man to change at least 11 people's lives by a sport

In conclusion, I think coach carter is a powerful and breathtaking film, it has a lot of strong messages on the movie which would head towards teens and their lives. It also helps teens get there heads straight for all the good things that can happen to you through sports 

Rates of Reaction

Experiment 1

Investigating the effect of temperature on reaction rate

Equipment

• A beaker, conical flask
• Measuring cylinder
• Stopwatch
• Black cross on paper
• water bath
• thermometer
• 0.1mol/L sodium thiosulfate
• 1.0 mol/L hydrocloric acid

Method

• Put the X paper on the bench mat,and put the conical flask on top of the paper
• Measure 50mL of sodium thiosulfate solution and put it in the beaker
• Record the temperature of the sodium thiosulfate
• Measure 5mL of HCL and pour into the conical flask 
• Pour the sodium thiosulfate into the conical flask, start the stopwatch and swirl the flask. Time how long it takes for the cross to disappear when viewed from above (i.e. look down the mouth of the conical flask)
• Wash out the flask thoroughly
• 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 the acid the same each time 

Results
 Room temp  - 27sec
30 degrees - 8sec
40 degree - 7sec
50 degrees -5 sec

Conclusion:
A chemical reaction is when two reactant particles collide.
They must collide with enough force and in the correct orientation.
As I increased the temperature, the reactants gained more kinetic energy and moved faster.
The faster they move, the higher the chance of a successful collision.
This means the rate of reaction will increase.

Experiment 2
Investigating the effect of concentration effects the reaction rate

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

Equipment

• Conical Flask
• Beaker
• Measuring Cylinder
• Stopwatch
• Waterbath
• Paper with a black cross "X"
• Thermometer
• 0.1mol/L Sodium Thiosulfate
• 2.0mol/L Hydrochloric Acid

Method

1. Put the piece of paper with the X on the bench and put the conical flask on it.
   
   
2. Measure 10mL of Sodium Thiosulfate and put it into the conical flask.
   
   
3. Measure 40mL of Water and put it into the conical flask. Swirl to mix.
4. Measure 5mL of HCl.
5. Pour the HCl into the conical flask, start the timer and swirl the flask.
6. Stop timing when the you can't see the cross on the paper.
   
   
7. Wash out the flask thoroughly.
8. Repeat experiment 20mL of Sodium Thiosulfate and 30mL of Water.
9. Repeat experiment 30mL of Sodium Thiosulfate and 20mL of Water.
10. Repeat experiment 40mL of Sodium Thiosulfate and 10mL of Water.
11. Repeat experiment 50mL of Sodium Thiosulfate and 0mL Water.

Results:

10mL Thiosulfate/40mL Water took 360sec for the X to disappear.
20mL Thiosulfate/30mL Water took 100sec for the X to disappear.
30mL Thiosulfate/20mL Water took 64sec for the X to disappear.
40mL Thiosulfate/10mL Water took 47sec for the X to disappear.
50mL Thiosulfate/0mL Water took 30sec for the X to disappear.

Experiment 3
Investigating the effect of surface area on reaction rate

Aim - I want to investigate how changing the surface area effects the reaction rate
Equipment:

• Boiling tube
• Calcium carbonate (marble chips)
• Calcium carbonate powder
• 1.0mol/L Hydrochloric acid
• Measuring cylinder
• Spatula
• Test tube tongs

Method: 

• Measure 2mL of hydrochloric acid and pour it into a boiling tube
• using the tongs to hold the boiling test tube over the sink, add a pea-sized amount of Calcium Carbonate powder.
• Repeat experiment instead using the same amount of marble chips rather than the powder

Results:

When I added the powder, there was vigorous fizzing.
When I repeated the experiment with the chips, it bubbled.

Conclusion:
A chemical reaction is when two reactant particles collide.
They must collide with enough force and in the correct orientation.
As I increased the surface area of the reactants, there were more reactant particles that were able to react. The more particles, the higher the chance of a successful collision.
This means the rate of reaction will increase.

Experiment 4
Investigating the effect of a catalyst on the reaction rate

Aim - I want to investigate how adding a catalyst will effect the reaction rate
Equipment

• Test tubes x 3
• Zinc metal granules
• Copper metal powder
• 1.0mol/L Hydrochloric acid
• Measuring cylinder
• Spatula

Method 

• Put a piece of zinc into test tube 1 and test tube 3
• Put a small amount of copper powder into test tube 2 and test tube 3
• Add 5mL of acid to each test tube

Results 

Test tube 3 bubbles and fizzed the most because the catalyst lowered the activation energy.

Conclusion:

A chemical reaction is when two reactant particles collide.
They must collide with enough force and in the correct orientation.
A catalyst is a chemical that itself is not used in the reaction, however it lowers the Activation Energy - the amount of energy required for a successful collision.
If less energy is needed, then more particles will have the required energy to react, therefore the reaction rate will increase

Projectile motion/Gravity work

Projectile motion..

A projectile Is anything that flies through the air

Projectile motion is the way the projectile moves through the air

What are the projectiles we have in sport?

Throwing a Basketball

Shooting a Netball

Kneeling - it was harder because it takes more force for the ball to reach your partner

Standing - it was easier because you were able to use force summation

If the ball got more height it would reach your partner better.

Gravity

What does gravity actually do?

Gravity is what brings an object back down and pulls it to the centre of the earth

The rougher something is the more air resistance it has

Which object has the most air resistance? basketball/netball/football

Basketball - basketball has the most surface area and its heavier which means that it will have the most air resistance

To throw a basketball as far as you can you would want to use your momentum and force summation to get the most power and force out of your pass as possible. A run up would also be another great way to get the force and the most power out of a long distance pass.
