Math - Fractions - Essay Example The right side on the other hand processes holistic information: visual input, emotion, artistic & 3-D sense, imagination & creativity and music & rhythm (Sobanski, 2002, p.3). It is known that 75% of what we learn is from the sense of sight (Sobanski, 2002, p.2). Equivalent fractions taught with visual aids, combine image and logical reasoning to get both sides of the brain working at the same time. This facilitates effective learning. Jessika Sobanski (2002) tells us some tips on creating a whole brain learning environment: Active-participant Learning. The class proper operates in a way that learning is active and is propelled by adult guidance and by social influences of group interaction and teamwork (Ben-Avie, Ensign, & Haynes, 2003). Active-participant Learning allows the thinking process to be made visible so teachers can intervene to improve faulty or ineffective patterns in a meaningful way. Ben-Avie et al. (2003) in their book, How Social and Emotional Development Add Up, conducted an evaluation of a certain urban school district. Their findings tell us that higher mean scores in mathematics concepts and application skills can be achieved by the following: Employ the active participant model in the classrooms and engage students in intellectual discourse. Divide your class into groups. Have one group answer the questions on equivalent fractions thrown by the other group. Reverse roles after one round of questioning. Be attentive to their answers and questions. Intervene in a respectful way when mistakes occur. Ask probing questions. You can ask your students â€Å"What makes equivalent fractions the same?† This can be an assignment they can ponder at home. (Answer: When you multiply or divide  both  the numerator and denominator by the same number, the fraction keeps its value.) Personalized Mathematics Lessons.

World’s Top 10 Coffee-Producing Essay Example for Free

World’s Top 10 Coffee-Producing Essay Coffee is the world’s second largest traded commodity it is used not only for drinking but for soft drinks and cosmetics as well, it is second only to oil according to all imports and exports from all countries. They are two main types Arabica coffee (most people are used to this and are more popular) and there is Robusta coffee. In the last two years the prices of coffee have been gradually falling (Ycharts. (2013). Coffee Arabica Price) alongside this, the supply of coffee has also been falling. Although there have been some price fluctuations at times and this could end up really affecting an economy that depends on coffee. The reason that this is such a big deal is because the countries that heavily depend on coffee exports are usually developing countries and with the price of coffee falls, so does their rate of development, these countries involve countries such as Vietnam, Ethiopia, Peru and Guatemala who are all within the world’s top ten coffee producers (Justin Doom. (2011). World’s Top 10 Coffee-Producing Countries in 2010-2011). When these economies are weakened, they face to their governments, who need to somehow intervene in the coffee market and try to stabilise the prices so that they can reach their ultimate goal to continue to develop. Price stability in the coffee market is an ideal scenario in a market where the prices for coffee do not alter drastically. They may raise a little or fall, but never by a noticeable amount, and are easy to predict, which can help coffee producers plan for the far future. It is not only important to coffee producers, but to the economy as whole, if the prices for coffee are unstable, for some countries this could have a huge impact on the inflation levels. The diagram below describes how an unstable price for coffee can increase and affect the short run aggregate supply and cause the general price level for the economy to rise and therefore causing inflation as they did in July 2012 (Ycharts. (2013) There are several reasons why the prices of coffee have been fluctuating, but still gradually falling. The first reason is that coffee or coffee beans are extracted from plants. These plants must first be grown, then harvested. There is only so much mankind can do to ensure that there is always excess coffee however sometimes natural disasters can occur, and there is nothing that farmers can do to prevent this, when natural disasters occurs it means that farmers will have small yields and supply for coffee will be low, for  example Colombia, one of the world’s leading coffee producers and exporters, in recent years have been experiencing poor weather conditions which have led to production falling by 12% to 7.809 million bags in 2011 which is a record low that hasn’t been seen since 1976. This can cause the price to increase seeing as coffee is the world’s second most demanded commodity. These poor conditions consisted of excessive heavy rainfall, disease, pest and limited sunlight (Zacks Equity Research. (2012)). The graph below shows how the supply for coffee has decrease leading to a rise in price On the other hand this is just an example for Colombia and for the rest of the world the prices for coffee have been falling for the last four years, this is due to wealthy individuals and companies use their money to invest in the global coffee suppliers, and other large coffee producers such as Brazil (the world number three) has been turning out high yield and is expected to do so in following years. Fain Shaffer, president of infinity trading crop expects coffee to be traded by one dollar to a pound of coffee, figures which have not been seen since September 2006. (Alexandra Wexler. (09/17/2013)) Coffee prices may currently be relatively stable at the moment however according to research conducted by the Royal Botanical Edinburgh along with Ethiopian scientists and London’s Botanical Garden, Kew, have predicted that wild Arabica coffee will be extinct by the year 2080. If the prices beg in to fall, all of a sudden the prices for coffee will no longer be stable. No country operates on a 100% free market. All economies are mixed, some tend to be freer than others, however should a country find that prices are volatile or unfair, they can always rely on the government to intervene, aka government intervention. One way a government could help stabilise the price of coffee is through buffer stock schemes, these schemes focus on the prices of coffee and try to stabilize the price, they do this by first establishing the intervention price, this is a price the government thinks is most suitable for coffee. Once this has been established the government will then buy up a lot of coffee when the price is at its lowest, they continue to do this until prices for coffee begin to rise again, and to balance out the price to make sure it is at the intervention price. They are constantly buying coffee to balance out the price. This is an effective method in theory however in real life they do not work out as planned because the people in charge of the buffer stock  tend to get greedy and try to max imise profits rather than help the economy as a whole and end up just constantly buying till they go bust. A good example of a successful buffer stock scheme is in Brazil, for years Conab, Brazil’s official crop bureau has been buying coffee at low prices and uses it to help local producers when the selling price for coffee is too low. Between 2003-2004 Conab had just under four million KGs accumulated. (Geoff Riley. (2012)) Another issue with this is that it is very difficult for a government to raise enough money to buy up enough coffee to influence the natural supply and demand. It is also expensive to store large amounts of coffee and because it is an agricultural good it has a shelf life. Another method the government could intervene is through Subsidies. A subsidy is a grant given by the government in order to increase production, this would help producers who have produce low yields due to high taxation and or high costs If the government could make coffee more attractive this could help stabilise the price if supply started to fall. This however is not a very effective meth od because it can only help bring the supply of coffee back up, and it may be able to work to well, if producers begin to produce excess supply the prices of coffee could start to increase sharply leaving the prices unstable yet again. Buffer stock schemes are the most ideal way for a government to ensure price stability, and the success of the scheme depends heavily on whether or not the Government can provide proper facilities to accommodate huge quantities of coffee and are able to afford to buy enough Coffee to be able to alter the market forces so that if prices go to high they can bring them down and if they go to low that they can bring them back up again, if not it could result in huge losses for the economy and even end up setting the country back. The supply and demand of coffee can and always will be prone to quick sudden changes due to circumstances that are unavoidable.

The Effect of Temperature on the Rate of Reaction :: GCSE Chemistry Coursework Investigation

The Effect of Temperature on the Rate of Reaction Plan We must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. There are five factors which affect the rate of a reaction, according to the collision theory of reacting particles: temperature, concentration (of solution), pressure (in gases), surface are (of solid reactants), and catalysts. I will investigate the effect temperature has on a reaction. Aim To investigate how a change in temperature effects the rate of a chemical reaction. The reaction that will be used is: Sodium Thiosulphate + Hydrochloric Acid --> Na2S2O3(aq)+ 2HCl(aq) Sodium Chloride + Water + Sulphur Dioxide + 2NaCl (aq)+ H2O(l)+ SO2 (g)+ Sulphur-S (s) Prediction I predict that as the temperature is increased the rate of reaction will increase. This means that the graph drawn up in my analysis will have positive correlation, and will probably be curved as the increase in rate of reaction will not be exactly the same as the temperature is increased. This can be justified by relating to the collision theory. When the temperature is increased the particles will have more energy and thus move faster. Therefore they will collide more often and with more energy. Particles with more energy are more likely to overcome the activation energy barrier to reaction and thus react successfully. If solutions of reacting particles are made more concentrated there are more particles per unit volume. Collisions between reacting particles are therefore more likely to occur. All this can be understood better with full understanding of the collision theory itself: For a reaction to occur particles have to collide with each other. Only a small percent result in a reaction. This is due to the energy barrier to overcome. Only particles with enough energy to overcome the barrier will react after colliding. The minimum energy that a particle must have to overcome the barrier is called the activation energy. The size of this activation energy is different for different reactions. If the frequency of collisions is increased the rate of reaction will increase. However the percent of successful collisions remains the same. An increase in the frequency of collisions can be achieved by increasing the temperature, concentration, pressure, and surface area. Also I predict that if the temperature is doubled, then the time taken for would be more than half because not only would the particles be moving faster to create more collisions, but they would also have more energy so there would be more successful collisions

Marketing Research Rocket Soup

Question 1 (a)Total Volume One of the most notable patterns of sales in regards to total sales volume is that it increases drastically when the average price of soup is low (Average price is calculated by dividing Category Volume by Category Dollars). Total sales volume had significantly increased when either Rocket Soup or competitors (or both) offer low price for promotion. In other words, soup consumption is relatively elastic to price, meaning that customers are highly sensitive to price. See below graphs showing the inverse relationship between the total volumes sold and average price of soups.Category Volume sold in Week 1 to 40 Average Soup Price in Week 1 to 40 (b)Total Spending Sales pattern in terms of total spending follows the pattern observed in total volume section. One notable difference is that the total spending per week is relatively more concentrated closer to the average total spending in 40 weeks (5,263), meaning it is not as elastic as the volume. It means that customers may purchase more soups when the price is lower, but does not dramatically increase their total spending, even if the price is very low.It can also be observed that the total spending (or revenue) does increase when the total volume sold are relatively larger, with the exception of week 12, where Rocket Soup charged unbelievably low price (0. 04). (c)Competition Another notable pattern is that the sales volume of Rocket Soup is significantly affected by competitors’ price and sales volume. When Rocket Soup offers cheaper price, the sales volume of Rocket Soup increases and competitors temporarily lose market share, and vice versa.It would represent that the size of the market is relatively capped and cannot expect a drastic increase over time. (d)Sales Volume after high volume weeks In general, the average sales volume after high volume weeks is lower than the average category volume. From the table 6-3, it can be observed that the average category volume per week i s 6,916, and the average of the top 5 sales volume weeks is 14,841, with the average category price of 0. 55. The following weeks of those top 5 weeks are Week 3, 9, 13, 32 and 38. From this period, the average sales volume is 5,184, with the average price of 0. 6, which is close to the average category price of 0. 82. From this, it could be argued that the sales volume after high volume weeks tends to significantly decrease even though the price remains the average level, as the excessive demand from previous week has eliminated demands for following weeks. Question 2 (a)Incremental Volume to Rocket In week 12, sales of Rocket Soup had drastically increased to 16,113 due to the excessive discount on their product. Rocket Soup had launched a promotion with feature and display and charged for 0. 2, which is over 97. 5% discount on their average price. Although the sales had drastically increased, it is not possible to argue whether this excessive demand was from the promotion or low pricing. (b)Promotional Volume burrowed from future sales Since Rocket Soup virtually gave away their product for free in week 12, the average sales volume of Rocket Soup has been lower until week 22. The average weekly sales volume of Rocket Soup was 1613, and yet the average from week 13 to 21 was only 718, which is less than half.In addition, Rocket Soup performed promotion on week 13, 16 and 19, and yet does not significantly increase any sales due to the previous high sales volume in week 12. Question 3 Although the general price and demand curve in economic would suggest the demand will increase when price is low, there are no significant relationship observed between sales volume and price when no promotion was conducted. The average price without promotion was 0. 90 and the standard deviation was only 0. 128.On the other hand, the average volume sold was 392 with a standard deviation of 129. 16, meaning it is relatively more randomly varied. In addition, the correlation betw een the two variables is only 0. 0128, meaning that it has almost no linear relationship altogether. Thus, it is safe to argue that there are no noticeable relationship between price and volume without promotion. Question 4 Unlike price and volume relationship with no promotion, there are a noticeable relationship between price and volume with display promotion.In week 37, the price with display was the lowest among 40 weeks, priced at 0. 74, and sold the most volume of 2,409. Also, week 8 and 34 showed the lowest sales, when price was charged higher. In other words, the price and volume relationship with display promotion does follow general economic principle of supply and demand, and it has inverse relationship. Correlation of price and volume with display promotion was -0. 486, meaning that it is negatively related, and does sell more when price is low, and vice versa.

Is your house your home essays

Is your house your home essays Your environment and the people you grow up with may be your house but it doesnt necessarily mean it is home to you. Its not your parents or the people you have to live with. The people you live with arent the people that influence who you are; its the people you look up to. Whether they be a teacher, your friends, somebody on T.V. or just a dream. Your parents and your environment can be incredibly abusive whether it be physically or mentally abusive to you, but everybody has there own dream and perceptions of how thing are supposed to be. Children know right from wrong with or without there parents help. There are always outside influences, teachers have a huge impact on a children. Everybody has that one teacher that will always stick out in their head, and not because of the negative effect but the positive impact they had on them and how that teacher reached out to them. Television could have a positive effect in a lot of ways. It has some negative effects, too but theres always something good to. Even though sitting in front of a television all day is not healthy there are a lot of programs that show families and how positive they are. In the past few year I've noticed that the media is starting to put positive messages in there advertising. For example Ive heard stay in school, stop the violence, help one another, and join in your community. All of these young children hear and it does not matter if their parents are wrong in how they have chosen to raise their children.
