...GCSE DOUBLE AWARD SCIENCE INVESTIGATION Title: Investigating how concentration changes the rate of a chemical reaction | Name: Ryan Bradley | Class: 12A1 | What is the aim of this experiment? To investigate how concentration hydrochloric acid affects the rate of reaction between sodium thiosulphate and hydrochloric acid and water. P.6a: List all the factors that could have an effect on the results in this investigation? * Concentration * Temperature * Surface area * Catalyst * Colour of the X * Stirring the mixture * Water in the beaker from washing out beaker P.6a: P.8a: Explain in detail how each of the factors you named could affect the investigation? Surface Area: This would affect my investigation because if there was a bigger surface area this means the particles have more room to collide as they are more exposed to head on collisions Concentration: If I was to increase the concentrations of the hydrochloric acid by too much/ little this will make my results unreliable because the more hydrochloric acid the more successful collisions and this would increase the rate of reaction. Stirring the mixture: This would affect my investigation because if I was to stir the mixture it would speed up the reaction time as you are creating more collisions meaning the ‘x’ will disappear quicker. Temperature: If I was to increase the temperature this would affect my investigation because it would mean the particles would gain more energy and this would...

...Soccer Soccer is the World Game, and is the one and only Football in many parts of the world. It is played in all corners of the world and its popularity is shown by the big stage of The World Cup held every four years. It is played with a round ball (traditionally with black and white checks), which is only kicked by the feet. This excludes the goal keeper, who can use hands only in the goal area. A goal is scored when an attacking player kicks the ball into the opposition net. Games are usually low scoring. There are 11 players on the field, with some substitutions coming late in the game. If a player is substituted off they cannot come back onto the field. The game consists of 45 minute halves, with a half time break. Players are not allowed to come off the ground during playing time Fitness for soccer consists of: Physical fitness is one of the most important aspects of soccer performance. A skillful player will go a long way in the sport, but without the fitness part of their game they will not be the complete player. Aerobic endurance fitness is one of the most important physical fitness attributes for soccer players. Players need to be able to maintain a high level of intensity throughout the 90 minute game. Another very important fitness component is anaerobic fitness, which means running speed and particularly repeat sprint ability. Players also need good agility, strength, power and flexibility. Training for soccer consists of: Regular training is needed for all...

...I was staring down a 6 foot giant who appeared even taller from my perspective, he was impossibly bulky an immovable object fully armored and ready to do damage. He already injured somebody and it seemed I would meet the same fate all I was armed with was a stick. The classic tale of David vs. Goliath entered my mind as I was cradling the lacrosse ball charging at the inhuman individual playing defense. I dodged the incoming offensive players with ease, passing the ball between my teammates got me deeper into our opponents territory and near the goal, I had possession of the ball with little time to win the game I ran at the goalie and the behemoth guarding the goal I jumped, high enough that I saw an opening above the giant and the confused goalie that could not see my incoming attack around him. I launched the ball everything after happened so fast I saw my shot ricocheted off the goalies shoulder as the defense man brought his arm down colliding with my chest. At this point, I got nauseous and light headed, so I had to walk around taking deep breaths to resist whatever it was in my stomach from exiting out my mouth. The pain was starting to stir, making me very anxious to fix whatever was wrong Coach grabbed my arm and reassuringly told me, "Relax; you have to relax." I took one more deep breath relaxed as much as possible the pain was still crazy as ever. That day we had a game against Marquette, the team we think we hated more than any other team. Oh boy were we...

...Juan Marcos Romero ENG 108 Armory Kaiser 27 February 2012 A Better Life Movie Analysis In the movie A Better Life, the Main Character Carlos Galindo is an undocumented immigrant from Mexico who started working as a day labor worker when he first arrived in the country, however he has had steady work from Blasco Martinez who owns a gardening business which he tries to convince Carlos to buy from him as he says he is moving. The idea of being self employed is very appealing to Carlos but he knows he can never afford to do so and the risk of getting caught and deported is very high. Carlos has a son Luis who is reluctant to go to school on a daily basis and gets into trouble as he is influenced by his friends who are part of the South Central gang life style. Carlos and his wife came from Jalisco which is a state in Mexico which is primarily made up of several small villages where "Charros" or Mexican cowboys would get married and head north to start a new life in America. Carlos believed that life in America would be simple in which if you worked hard opportunities would present themselves and you could be happy, that unfortunately was not the case and Carlos's wife ended up leaving him alone with their young son Luis. The main difficulties that Carlos and Luis face are that they live in a rough neighborhood in south central Los Angeles and even though Carlos has what seems to be a steady job with Blasco, Carlos is unable to save up the money needed to move to a better...

...are many diverse positions. Upon those positions, the goalkeeper is one of the arguably one of the most mentally and physically taxing position on the field. Because of its dynamic duty, goalkeepers have a high risk of receiving a concussion. But what is a concussion? A concussion is a traumatic brain injury that is caused by a blow to the head, a fall, or another injury that jars or shakes the brain inside the skull. Severe concussions can cause long lasting effects that can permanently affect an athlete’s career and everyday life. Finding a way to not only treat concussions more efficiently but prevent them altogether would completely change how athletes play soccer. Concussions rates have increased as the popularity of physical sports has increased, raising the rates and the liabilities for the athletes have experienced a concussion before. The American association of neurological surgeons, the author of “Conditions and Treatments of Concussion”, claims the rates of concussions in players of physical sports, such as soccer, and the percentages within college athletes. As a credible medical organization the article states that “...McGill University in Montreal found that 60 percent of college soccer players reported symptoms of a concussion at least once during the season.” Concussions are an injury every athlete...

In the sport of Football, the game itself last 90 minutes, split into two equal halves of 45 minutes, with a 15 minute break in between. In Football, the sizes of each individual pitch varies depending on styles of football played by each team (if a team likes to play possession football and use width then pitch could be long and wide, where as if a team plays with a more direct approach then the pitch could be shorter and more narrow), however, these are the dimensions required by law: The length of a pitch must be between 100 yards (90m) and 130 yards (120m) and the width not less than 50 yards (45m) and not more than 100 yards (90m). With football being a fast, free- flowing game, there are very few breaks in play throughout the game other than for set pieces or throw ins. Analysing from Player’s Perspective Being a goalkeeper is one of the major positions on the football pitch, if not THE most important, as it is the most specialized position in the sport. The goalkeeper's primary role is to prevent the opposing team from successfully moving the ball over the goal-line (between the posts and under the crossbar). This is accomplished by the goalkeeper moving into the path of the ball and either catching it or directing it away from the vicinity of the goal line. Within the penalty area goalkeepers are able...

...a goal. The team that has scored more goals at the end of the game is the winner; if both teams have scored an equal number of goals then the game is a draw. Each team is led by a captain who has only one official responsibility as mandated by the Laws of the Game: to be involved in the coin toss prior to kick-off or penalty kicks.[7] The primary law is that players other than goalkeepers may not deliberately handle the ball with their hands or arms during play, though they do use their hands during a throw-in restart. Although players usually use their feet to move the ball around, they may use any part of their body (notably, "heading" with the forehead)[8] other than their hands or arms.[9] Within normal play, all players are free to play the ball in any direction and move throughout the pitch, though the ball cannot be received in an offside position.[10] In typical game play, players attempt to create goal-scoring opportunities through individual control of the ball, such as by dribbling, passing the ball to a team-mate, and by taking shots at the goal, which is guarded by the opposing goalkeeper. Opposing players may try to regain control of the ball by intercepting a pass or through tackling the opponent in possession of the ball; however, physical contact between opponents is restricted. Football is generally a free-flowing game, with play stopping only when the ball has left the field of play or when play is stopped by the referee for an infringement of the rules. After...

...interaction of the players during the games are also quite similar for both games. Most of the times, a lot of people may think that have no differences between futsal and football. In contrast, that has some differences between two games. First of all, the differences between futsal and football are the rules of the games. For futsal, they are only 20 minutes in a game which is shorter of the time period comparing to football. During the games, no offside rules available in the futsal games and the players sent off can be substitute after 2 minutes. The goalkeeper can hold the ball for 4 seconds and that is no pass back to goalkeeper. While for the football game, the game only contains 45 minutes of the time period. Other than that, the offside rules are available in this game and that is no substitutions happen for players sent off. There is no time limit for goalkeeper to hold the ball and I can pass back the ball to the goalkeeper once the ball was kicked out. Furthermore, venues for both of the games are totally difference. Let’s talk to the futsal game first, for the futsal, the venue of the game should be run through over hard court surface. The length of the court may be around 38 to 42 meters and the width is between 38 to 22 meters. Instead, for the football game, the game runs through over soft surface which is on the field.

Positions in Soccer requires all of these skills but every position needs combination of different skills to stay in the game. The midfielder is the position that requires the most physical effort. The midfield player has a lot on his plate because he has to be able to run back and forth the full length of the field at times which he needs to be physically fit.
