Concentration and rates of reaction Essays

Concentration and rates of reaction Essays Concentration and rates of reaction Paper Concentration and rates of reaction Paper I am investigating the effect of the concentration of Hydrochloric Acid on the speed of the reaction between Sodium Thiosulphate and Hydrochloric Acid. When these react together, sulphur is formed. A balanced chemical equation for the reaction is Na2S2O3 + 2HCl S + 2NaCl + SO2 + H20 Apparatus Total of 10cm3 of distilled H20 Total of 15cm3 of HCl Total of 125cm3 of Na2S2O3   Paper with cross to see how long it takes for cross to disappear under flask Conical flask to hold solutions needed for experiment   2 measuring cylinders to measure out correct amounts of solutions. 2 beakers and 2 pipettes to contain solutions before going into the conical flask. The pipettes are for accurate measuring of the solutions. Method 1. I will put a big black cross on a piece of paper, the size of the bottom of the conical flask. 2. The conical flask will be put on the paper. 3. 25cm3 of Sodium thiosulphate will be added to the conical flask. 4. Added to the Na2S2O3 (Sodium Thiosulphate) will be 5cm3 of Hydrochloric acid. 5. I will then time, from when the HCl was added, until the view of the cross is blocked. I will do this using a stopwatch. The liquid should turn yellow from colorless. 6. I am going to use different concentrations of hydrochloric acid. I will obtain the different concentrations of HCl by adding ratios of water to the HCl. The total volume added each time will be 5cm3, to make the total volume inside the conical flask 30cm3. Each time, I will use the following concentrations; Experiment 1: 0cm3 H2O 5cm3 HCl 25cm3 Na2S2O3 Experiment 2: 1cm3 H2O 4cm3 HCl 25cm3 Na2S2O3 Experiment 3: 2cm3 H2O 3cm3 HCl 25cm3 Na2S2O3 Experiment 4: 3cm3 H2O 2cm3 HCl 25cm3 Na2S2O3 Experiment 5: 4cm3 H2O 1cm3 HCl 25cm3 Na2S2O3 7. I will repeat the experiment twice in order to get a more accurate result, as an average will be obtained. Prediction The faster the reaction takes place, the shorter the time needed for the reaction to finish. To be more precise, the speed of reaction is inversely proportional to the time taken for the reaction to finish. If the acid concentration doubles, the speed doubles. The reason for this is that the ions are closer together in a concentrated solution. The closer together they are, the more often the Sodium Thiosulphate ions and Hydrochloric Acid ions collide. The more often they collide, the more chance they have of reacting. I, therefore, predict that with the acid concentration decreasing, it will take longer for the cross to disappear. Fair test To justify my prediction, the following factors need to be controlled to obtain accurate results;   The person watching the experiment will be the same each time as it is a judgement that only the same person would note.   I would need to use the same equipment all the time I need to keep the pipettes in the right beakers because of they werent, I could get a reaction that I do not want and that would mean that one conical flask will have either more or less HCl than required. This would be unfair to the experiment.   I am changing the concentration, which means the temperature will have to stay the same. If the temperature was to change, the experiment would be unfair. With colder water, the particles move slowly and do not collide very often. If you increased the temperature, the particles would begin to move faster with greater energy. They will collide more often with many more collisions being successful than before. This is because temperature affects the amount of kinetic energy the particles have and therefore the reaction time. Results 0. 05M of Sodium thiosulphate 2M of Hydrochloric acid 60cm3 5cm3 Volume of Thiosulphate cm3 Volume of water cm3 Time taken for X to disappear seconds Average time taken seconds 1st test Repeat 1 Repeat   All averages are rounded to nearest whole number The averages are plotted on graph (1) overleaf Concentration/M Rate. These results are plotted on graph (2) overleaf Analysis The faster a reaction takes place, the shorter is the time needed for the reaction to finish. This is true with my results, as with the highest concentration of Hydrochloric Acid present, the time taken for it to react was greater than any other concentration of HCl. Looking at graph (1), I can see only one anomalous result. This is the reaction between 10cm3 Thiosulphate and 50cm3 water. The average time taken resulted in 1169 seconds. This seems unlikely as with 15cm3 Thiosulphate and 45cm3 water, the average time taken is 622 seconds. Possible reasons for the anomalous results could have been down to either poor observation skills, or not rinsing the conical flask out properly. There could have been more water in there than anticipated, therefore making the solution less concentrated than it should have been. The 622 seconds result fits in well with the other results and forms a pattern of a smooth gradual decline curve on the graph. The anomalous result makes the graph flatten out at the bottom of the curve. When drawing the line of best fit, I did not include the anomalous result. The graph does show the trend that when the volume of thiosulphate is decreased the time taken decreases also. Looking alternatively to graph (2), there does not seem to be any anomalous results. The points join up to make a smooth upwards curve on the graph. The line of best fit is placed between all of the points, this works well as there are an equal amount of points on either side, with them all spread fairly evenly along the curved line. This links in very well with my prediction that with a higher concentration, the rate of reaction is faster. Evaluation. My method worked well because I was able to get a set of results at the end. However, there were a few problems. On graph (1) there was an anomalous result, and because we did the experiment over two days, we could not use the same apparatus as the day before. The stopwatch however was the same, so we were able to get as accurate results as the previous day. Graph (2) does not show any anomalies. Graph (1) shows a point that doesnt fit the pattern, as does the second point of graph (2). Even though the graph does join up fairly smoothly, the point is slightly out. This point has been circled on the graph. To make sure there are no anomalous results next time, you will need to follow the method and equipment list fully, and make sure the flask and beakers are cleaned out and dried before a new experiment is taken out. If done again, I would change the temperature rather than the acid concentration. When sodium thiosulphate and Hydrochloric acid are reacted together, Sulphur is formed. The temperature increase would make the Sulphur form faster. The ions would have more kinetic energy so would collide more often and more vigorously and so there is a greater chance that they will react.

Issues in Terrorism Essay Example | Topics and Well Written Essays - 750 words

Issues in Terrorism - Essay Example 230). However, the thing that needs to be understood is that in a historical sense, the definition of the term terrorism had been increasingly dependent on the interests and intentions of the powers who tried to define terrorism. Hence, the meaning of the term terrorism will always go on changing in the future in consonance with the agenda of the powers which extend the majority narrative. Before elaborating on the relativity of the definition of terrorism, it will indeed be insightful to try to circumscribe the concept of terrorism within the domain of some widely accepted commonalities. It is a reality that in all ages and times, terrorism did evince some common traits and characteristics. To begin with, it would not be wrong to say that terrorism does happen to be a radical and extreme genre of political manipulation (Stout, 2002, p. 65). Most of the times the terrorists do resort to acts of extreme violence to create an environment of uncertainty and intimidation so as to make people get convinced about the ubiquity and potency of their power and sway. The other particular thing is that the aim of terrorism is always to disseminate a pervasive sentiment of panic and fear. Besides, terrorists also resort to acts of violence to accrue media and popular attention. Also, the most important thing about terrorism is that it contradicts and defies the sacrosanct human va lues and aspirations. Now, if one considers some of these characteristics that are common to the configuration of a viable definition of terrorism, it is possible to contrive a definition of terrorism which may not be concrete, but still manages to convey a malleable meaning and intent that could be grasped by human logic and ethics. However, the sad thing is that if one takes into consideration the historical realities, the act of defining terrorism has always been subservient to the intent and aspirations of the dominant narrative. It is said that

The implementation of a statistical process control to ensure total Essay

The implementation of a statistical process control to ensure total quality management and identify solutions to satysfying customer needs and reduce waste in the company - Essay Example This is inherently present in the method of data collection that was put in place while conducting the primary analysis. In this case, the data that has been put forward in the report was collected by analyzing the colour defects in a random sample of 200 units and the height variance of dolls for a period of 30 days. For accuracy, charts and table were designed and analyzed. We used an Np-chart to plot data on the colour defects and a histogram for the height difference of the dolls as the appropriate Statistical Process Control charts to monitor the data. The Np-chart was used because the data on colour defects was prepared as counted time attribute data with a constant sample size. The following charts prepared in MS-excel show the findings of the report in details. Chart 1.0 Np-chart for the number of defective dolls The Np-chart shows how the process, measured by the number of nonconforming items such as the dolls it produces, changes over time. Chart 2.0 Histogram for the heigh t measurements of the dolls The histogram was a suitable choice because the data collected in the 30 days was a measured time variable data with columns of decimals. Discussion and Recommendation The results indicate that there is a problem in the company. More specifically, the problem is traceable to the production part of the company. Consequently, the managerial team of the company should act fast in implementation of effective measures some of which we have discussed in the recommendations provided. There is a high number of customer dissatisfaction due to inconsistent and non-uniform manufacturing. It is evident, from both the report as well as the data collected too, that for every 200units sampled at... This study looks into Tom pulling Toys Company, a well-respected major global manufacturer of educational toys for children. The company plans to expand its profit margin and crave towards becoming a market leader. However, with the current competition from China, the company is in the race towards changing its strategies to counter the completion and remain profitable. With such demands to find the ideal changes, a Statistical Process Control method has been put in place to solve this issue. This report gives the overview of the progress of the Processes control in detail. After investigating the variation in the height of dolls and the different colour schemes in the dolls sampled, it was found that the dolls are suitable for the market but fail to meet Total Quality Management that is in line with the company requirements. This results from production of dolls that are not within a competitive scope of the market and provides a leeway for companies in China to provide threatening competition to the sale of dolls and possibly other products which are also part of the products that the company produces. In any market, it is imperative to stay ahead of the competition in order to remain relevant and improve competitive edge. It is important to consider long term benefits to the company when designing and manufacturing given the quality of the products will be ultimately determined by the customers. Apart from handling the individual faults in the height and colouring of the dolls, the product quality needs to be defined with measurable and appealing characteristics that can win buyers.

A Study Of The Predictive Effect Of Pre-Service Teacher Essay Example for Free

A Study Of The Predictive Effect Of Pre-Service Teacher Essay ABSTRACT: This paper aims to examine the relationship between the personal knowledge management (PKM) competency of pre-service teachers and their instructional design skills. Supporting the sustainable development of teachers as professionals in the knowledge society is a critical issue in teacher education. This study attempts to identify an empirical model and a curriculum framework for nurturing pre-service teachers’ PKM competency. Dorsey (2000) PKM skills were adopted for constructing the theoretical framework and the survey instrument. A quasi-experimental research design was used to collect data from pre-service teachers from Hong Kong’s largest teacher education institution. A structural equation model was applied to explore the predictive power of PKM competency on their instructional design. Results show that a four-factor PKM competency model, which consists of retrieving, analyzing, organizing and collaborative skills, was identified as a predictor of instructional design. Use of PKM tools, e-learning activities and collaborative action research for developing pre-service teacher PKM competency are recommended to teaching education institute. Keywords: Personal knowledge management, Pre-service teacher, Teacher education Introduction Rapid advances in technology and communications have greatly accelerated the emergence of information. The increases in the amounts and formats of information available do not automatically make learners more informed or knowledgeable, if a learner cannot manage and meld the accumulation of  information through their daily experience and study to construct knowledge in a systematic fashion. This competency is referred by most literatures (Frand Hixon, 1999; Dorsey, 2000; Wright, 2005) as personal knowledge management (PKM) competency. Developing learners with PKM competency is not simply a lifelong education issue, it is also an important teacher education issue in terms of sustaining a competitive human capital in the knowledge economy. Teacher development is viewed as an ongoing lifelong learning process as teachers strive to learn how to teach learner to learn how to learn (Cochran-Smith Lytle, 1999). The recent education reforms in Hong Kong (Education Commission, 2000) addressed this lifelong education issue by proposing a learning to learn slogan in the policy document. The policy suggests that teachers should develop student learning competence for acquiring knowledge through various methods. To develop students with knowledge acquisition skills, teachers should also be equipped with the competency for knowledge acquisition. However, since publication of the policy paper entitled Information Technology for Learning in a New Era Five-year Strategy that launched IT in education in Hong Kong (EMB, 1998), the Education Bureau has not addressed this issue in any teacher professional development policy documents. Recent calls for consultation on e-learning from the Education Bureau likewise generated additional demand for developing teacher information literacy capable of supporting student learning (EMB, 2004). If the government and teacher education institutions really want to develop competent teachers for the knowledge society, they may consider injecting the elements of personal knowledge management (PKM) into the teacher education curriculum for developing pre-service teachers’ teaching competency. However, little studies on teacher education were attempted to examine the effect of PKM on teacher learning and discussed the possibilities of injecting the element of PKM model into teacher education curriculum. This study aims to construct an empirical model for examining the predictive effect of pre-service teachers’ PKM competency on their instructional design skills and to discuss a personal knowledge management curriculum framework for teacher education institutions. Literature Review A review of the literature related to knowledge management suggests that the development of personal knowledge management (PKM) could be a means of enhancing pre-service teacher professional competency in managing personal knowledge for coping with the acceleration of emerging information. Frand Hixon (1999) define PKM as a conceptual framework to organize and integrate important information such that it becomes part of an individual’s personal knowledge base. Dorsey (2000) emphasizes the importance of injecting PKM into an educational framework for undergraduate education in order to bridge the gap between general education and other subject disciplines. PKM could serve as a framework for integrating general education and majors and as an approach to technology integration initiatives throughout the curriculum. PKM provides learners with both a common language and a common understanding of the intellectual and practical processes necessary for the acquisition of information and its subsequent transformation into knowledge. The significance of exploring PKM may contribute to human cognitive capabilities (Sheridan, 2008). Scholars tend to conceptualize PKM as a set of information skills (Frand Hixon, 1999; Avery et al, 2001), though there is no standard definition or model for PKM. After Frand Hixon (1999) outlined five PKM techniques as searching, classifying, storing distributing, evaluating and integrating skills, Dorsey and colleagues (Avery et al, 2001) broadened the Frand Hixon PKM framework well beyond its formulation. Central to PKM, as clarified by Dorsey, are seven information skills which when exercised together are integral to effective knowledge work. These seven PKM skills are retrieving, evaluating, organizing, analyzing, presenting and securing information and collaboration for creating knowledge. Recently, Pettenati and Cigognini (2009) grouped PKM skills under three intertwined macro-competence categories: creation, organization and sharing. PKM can also be conceptualized as an intertwined macro-competency. Wright (2005) proposes a PKM model that links distinctive types of problem-solving  activities with specific cognitive andmetacognitive, information, social and learning competencies. As a learning competency, PKM enables learners to apply a set of learning skills that are essential to lifelong learning for information processing, knowledge application and decision-making. As a cognitive and metacognitve competency, it enables learners to apply complex thinking skills to solve problems. It is knowledge concerning the learner’s own cognitive processes or anything related to them (Flavell, 1976, p232). As an information competency, it enables learners to link technology tools with a set of information skills, thus providing an intentionality that moves the focus from the technology more directly to the information. As a social competency, its underlying principles include enabling learners to understand others’ ideas, develop and follow through on shared practices, build win-win relationships, and resolve conflicts. PKM integrates human cognitive and metacognitive competency (Sheridan, 2008), social competency (Wright, 2005; Pettenati Cigognini, 2009) and informational competency (Tsui, 2002). Wright (2007) has developed a PKM Planning Guide for developing knowledge worker PKM competency. The guide is based on his research findings that the four interrelated competencies are activated in order to plan PKM training. The training process encourages participants to reflect on their knowledge activities and focus on areas for improvement. If learners know how to control this process, they can internalize information into personal knowledge, creating a foundation for effective learning. Utilizing PKM for acquiring knowledge refers to a collection of information management processes that an individual learner needs to carry out in order to gather, classify, store, search, and retrieve information in his daily activities (Tsui, 2002; Grundspenkis, 2007). In teacher education, knowledge acquisition focuses on the process how teacher apply PKM to support their day-to-day teaching and learning activities: instructional design. Instructional design is closely related to PKM which is also one of the major learning tasks for pre-service teachers. Instructional design is a process that involves determining the current status and needs of the learner, defining the end goal of instruction, and creating instructional  and learning strategies to facilitate teaching and learning. There are a wide range of instructional design models, many of them based on the ADDIE model (Seels Glasgow, 1998; Molenda, M., 2003; Strickland, A.W. 2006) which includes the following phases: analysis, design, development, implementation, and evaluation. This acronym stands for the 5 phases contained in the model. Knowledge acquisition for instructional design is conceptualized as identifying learner entry skills, formulating instructional objectives, test and design specifications, creating instructional or training materials, making recommendations and preparing a project report for lesson implementation. As instructional design is one of the key components of teacher professional competence, and helps to implement a new curriculum in the information age of the 21st century, exploring the predictive relationships of PKM competency on knowledge acquisition for instructional design becomes key to the development of teacher education. Research Methodology It appears that PKM competency can expand individuals’ knowledge and enhance their learning competency (Davenport, 1997, p146 ; Frand Hixon, 1999). It provides learners with a targeted, reflective and adaptable cognitive framework for inquiry and problem solving. In this study, knowledge acquisition will be conceptualized as the knowledge required for carrying out instructional design. This study attempts to answer the following research questions: 1. What is the empirical factor structure of PKM competency for pre-service teachers? 2. Is there any relationship between the PKM competency of pre-service teachers and their knowledge acquisition for instructional design? This study adopted Dorsey (2000) PKM skills to conceptualize PKM as a competency for acquiring knowledge (see figure 1). A quasi-experimental research design was used in this study to determine the relationship between PKM skills and knowledge acquisition for instructional design. The exogenous variables were pre-service teachers perceptions of their PKM skills. The endogenous variable is knowledge acquisition for instructional design. A  self-response quantitative questionnaire was devised to collect data from the pre-service teachers of Hong Kong’s largest teacher education institution. Figure 1: Theoretical Framework Of The Study The operationalized definitions of Dorsey (2000) PKM skills are as follows: 1. Retrieving skill is the ability of learners to retrieve information from relational databases, electronic library databases, websites, threaded discussion groups, recorded chats, and moderated andunmoderated lists. 2. Evaluating skill is the ability to make judgments on both the quality and relevance of information to be retrieved, organized, and analyzed. 3. Organizing skill is the ability to make the information one’s own by applying ordering and connecting principles that relate new information to old information. 4. Collaborating skill is the ability  to understand others’ ideas, develop and follow through on shared practices, build win-win relationships, and resolve conflicts between these underlying principles. 5. Analyzing skill is the ability to extract meaning from data and convert information into knowledge. 6. Presenting skill is the ability to familiarize with the work of communications specialists, graphic designers, and editors. 7. Securing skill is the ability to develop and implement practices that help to ensure the confidentiality, integrity and actual existence of information. This study adopted ADDIE instructional design model to conceptualize instructional design as a multiple competencies that involves analysis, design, development, implementation, and evaluation of a lesson (Molenda, 2003; Strickland, 2006). The acronym ADDIE stands for the 5 phases contained in the model. Pre-service teachers’ learning on instructional design is conceptualized by the knowledge and experiences they come across in the 5 phases of ADDIE model including analysis, design, development, implementation and evaluation. The learning outcomes include know how to analyse learner characteristics and task to be learned and identify learner entry skills; to design learning objectives and choose an instructional approach; to develop instructional or training materials; implement the lesson and deliver the instructional materials; and to evaluate the lesson plan and recommend the materials achieved the desired goals. The teaching experience that they had gained include determining the current state and needs of the learner, defining the end goal of instruction, and creating some instructional and learning strategies to facilitate teaching and learning. Instructional design is operationalized to the knowledge for: identifying learner entry skills; formulating instructional obJectives, test and designs specifications; creating instructional or training materials; and making recommendations and preparing a project report for lesson implementation (Seels Glasgow, 1998; Molenda, M., 2003; Strickland, A.W. 2006). The questionnaire was based on a number of scales constructed to measure the variables of PKM skills and instructional design. In order to develop valid items for these scales, the researcher conducted a content analysis on the PKM literature of Dorsey (2000), Skyrme (1999). Hyams (2000), and on the instruction design literature of Seels Glasgow (1998), Molenda, M. (2003); and Strickland, A.W. (2006). The questionnaire consists of two sections. Section 1 was used to measure the effectiveness of knowledge acquisition for instructional design based on 4 items. Section 2 contains 21 items designed to measure the teachers’ perceptions of their seven PKM skills. Likert 6 point scales were used in both sections to measure the variables. Likert scales are commonly used in attitudinal research. The Likert scale assumes that the difference between answering agree strongly, and agree is the same as between answering agree and neither agree nor disagree (Likert 1932, quoted in Gay, 1992 ). The data was collected directly from target subjects using the questionnaire. 225 pre-service teachers responded to the survey. Data was collected directly from them by means of the questionnaire. The subjects in the study were pre-service teachers from Hong Kong’s largest teacher education institution. Random sampling was used to collect data from the population. Exploratory factor analysis was carried out on variables using principal factor axis analysis to confirm the constructed validity of the tools (see table 1). The study is interested in a theoretical solution uncontaminated by unique and error variability and is designed with a framework on the basis of underlying constructs that are expected to produce sources on the observed variables. Principal axis factor (PAF) analysis, which aims to reveal the underlying factors that produce the correlation or correlations among a set of indicators with the assumption of an implicit underlying factor model, was applied separately to the items from the learning processes and learning outcomes. Promax rotation, a method of oblique rotation which assumes that the resulting factors are correlated with one other, was applied to extract the factors. An eigenvalue greater than one was used to determine the appropriate number of factors for the factor solutions. A Structural Equation Model (SEM) was then applied to  examine the factor structures and the paths among the variables, using Lisrel 8.3 (Joreskog Sorbom, 1999). SEM is a collection of statistical techniques that allows the examination of a set of relationships between exogenous variables and endogenous variables. Findings The results of exploratory factor analysis, presented in Table 1, clearly suggest a four- factor structure for exogenous variables that are both empirically feasible and theoretically acceptable. An eigenvaluegreater than one was used to determine the appropriate number of factors for the factor analysis solution. Items were extracted with factor loadings greater than 0.6 across and within factors. The numbers of factor solutions extracted from a Promax rotation theoretically afforded the most meaningful interpretation. The process used to identify and label the factors that emerged was based on examining the derivation of the highest loading items on each of the factors. The reliability coefficients of the scales ranged from 0.792-0.821, which was judged adequate for this study. The results of descriptive statistics show that the scale means of all the variables are higher than 4.27 within the 6 point-scale, reflecting the participants’ tendency to slightly agree with all the items. The reliability coefficient (Alphas) of the scale for instructional design is 0.854, its scale mean is 4.33 (sd = 0.691).

Economic Divergence In Australia :: essays research papers

Economic divergence in Australia – it is an issue that I feel all Australians should be aware of and deal with, because if the gap is not bridged, then Australia's economic prosperity and social fabric will be under serious threat. Evidence of this divide is seen with the differences in unemployment rates and household income between the urban and rural regions. Australia's economy has sent inner-city employment levels through the roof - thousands of millionaires created each year by exploding real estate prices in Sydney and Melbourne have helped to feed a huge retail boom. This, however, goes only so far - there is a 'dark' side to our prosperity - Australia is experiencing a wealth divide, and areas in the bush and other rural communities are struggling for survival. Evidence may also be found in the city, where suburbs a few kilometres apart differentiate enormously in terms of income and unemployment rates. Take the bush, for example, where reliance on a single industry and a shortage of services creates a wealth of problems. Not only this, but low prices for key commodities such as wheat and wool is making life very tough for many rural communities across Australia. In terms of unemployment, the number of jobs in rural and mining areas has been on the decline and particularly in the past 15 years. At the other end of the spectrum, outlying suburbs of Sydney and Melbourne still face unemployment rates of above 10% because of the cutting back of employment in traditional industries such as textile, clothing and footwear, and vehicle manufacture. This can plainly be seen in Elizabeth, north of Adelaide, where almost one in four of those seeking work are unemployed and the suburb remains heavily dependent on the car industry. In terms of statistics, a huge contrast is evident with the unemployment rate in the Murraylands in South Australia at 11.3%, against the minute 2.9% in the inner-west of Sydney. This is underlying evidence of the variance between city and bush. The growing chasm may also be seen with the differences in household income, where in an area such as the Wide-Bay Burnett region in Queensland has barely half the household income of inner Sydney. It is predicted that during the next five years, many regions of Australia will struggle to achieve increases of household income of up to $1000, while the 'global' city segments of Melbourne and Sydney can expect increases of between $6000 and $8000, an enormous contrast.

Argumentative Essay on Teen Pregnancy

Teenage pregnancy is a major issue in the United States. Some people say that this is society’s fault. Although having sex and getting pregnant is due to personal choices and decisions, there are a few things society could do to prevent it. Excessive teenage pregnancy could be controlled with appropriate media, more readily available birth control, and people to set good examples for young women. Just flipping through the channels on a Saturday afternoon you can see all sorts of inappropriate media full of sexual suggestions.Even aside from all the sex scenes in movies, there are shows SPECIFICALLY about teen pregnancy. Shows like Teen Mom and 16 and Pregnant make pregnancy seem acceptable and cool. If having sex at young ages didn’t seem like the cool thing to do, many teens wouldn’t do it. Taking inappropriate shows and movies off the air could make a difference in the teenage pregnancy rate. There are many forms of birth control.In a lot of arguments about tee n pregnancy there is talk about making condoms more readily available, but I think that other forms of birth control that are more consistently effective should be promoted instead. Condoms are important to use, but many times they can break or be ineffective. Plus let’s face it, in the heat of the moment lack of a condom doesn’t always keep sex from happening. Birth control pills are a cheaply made, more effective form of birth control. If forms of birth control such as the pill were cheaper and easier to get, more teens would be protected and less would get pregnant.The world in general is in need of good role models. Anyone that tweens and teens look up to should really try to focus on setting a good example. In a world full of bad examples, its especially important to set good ones for the group of people in that developmental stage. Teenagers need role models to protect them from falling victim to the pressures of today’s society, especially the sexual ones . In conclusion, I believe that teenage pregnancy is a very important issue.The sexual society of today’s America has resulted in a large increase in teen pregnancy. Programs that promote teen pregnancy and things that lead to teen pregnancy should be taken off every day television. Although it is going to be impossible to keep teens from having sex, making birth control extremely easy to use and get ahold of could have a huge effect on the teenage pregnancy rate. These two things along with good parental guidance and support, and good role models to look up to, would keep most teens from getting pregnant.

Elephant and Rhino Comparison - 1229 Words

The white rhinoceros and the Asian elephant possess many similar characteristics, including the way they look, yet also possess many differences such as the two continents they live on. There are five living species of rhino (black, white, Indian, Javan and Sumatran) and only two of the elephant (African and the Asian). All are in jeopardy of extinction with their slow rate of breeding, poaching and in the rhinoceroses, their territorial behavior. Both of these beasts belong to the same kingdom (Animalia), phylum (Chordata), sub-phylum (Vertebrata) and class (Mammalia). Meaning they are both back-boned mammalian, animals.
