Circulatory System Lab Report Essay Example

Circulatory System Lab Report Paper This will provide the blood with oxygen for the body. Oxygen can be entered through the mouth and the nose. (Author: Unknown, Year 2009 (Edited), Title: The Respiratory system, http://en. Wisped. Org/wick/Respiratory_system Date visited: 29/05/09) Heart Rates: The meaning pulse rate is exactly the same than a heart rate. The Pulse Rate/ Heart Rate is the dilation and contraction of the elastic muscular wall of the arteries. The Pulse Rate can be found in Arteries closer to the surface, for example; Carotid pulse in the neck and the Radial Pulse in the wrist. The heart rate can be increased or decreased for various reasons, For example; Exercise. The Harder and longer we exercise the more oxygenated blood is used by the cells, Therefore our heart rate increases so then oxygenated blood is pumped faster, as we exercise harder, The body uses more oxygen and inhales oxygen more frequently. This is because the cells in the body are working harder ND need fresh oxygenated blood faster to operate (Inhale to breathe in oxygen, Exhale to breathe out Carbon Dioxide). Group 1: activity Group 2: 30 Minutes No activity Aim: This experiment will prove how heart rates change with 30 minutes exercise a day Vs.. No exercise a week, and also the fitness levels after; gained and lost. Hypothesis: I think 30 minutes exercise a day will decrease the heart rate and increase fitness for Group 1. I think Group 2 will increase heart rate, decrease fitness and increase calories. Materials: Pen Record Sheets Stop watches Year 9 Students Method: Step 1: Students rested by lying down comfortably.

Steps: Students conducted 15 seconds of star jumps, then the pulse rate was recorded. Steps: Students conducted 1 5 seconds of star jumps, then the pulse rate was recorded. Step 5: Students conducted 15 seconds of star jumps, then the pulse rate was recorded. Step 6: Students conducted 15 seconds of star jumps, then the pulse rate was recorded. Step 7: Students conducted 15 seconds of star jumps, then the pulse rate was recorded. Step 8: Students rested by lying down or 15 seconds, then the pulse rate was recorded. Step 9: Students rested by lying down for 15 seconds, then the pulse rate was recorded. Step 10: Students rested by lying down for 15 seconds, then the pulse rate was recorded. Step 1 1: Students rested by lying down for 15 seconds, then the pulse rate was recorded. Step 12: Students rested by lying down for 15 seconds, then the pulse rate was recorded. (Each 15 seconds of each step represents % oaf minute, 15 seconds was then times by 4) (15 seconds X 4 = 60 seconds) Results: Personal average results: Pulse Description Pulse rate per 15 seconds X Resting Pulse (before exercise) 19 76 4 (Pulse rate per minute) After 1 minute exercise 27 After 2 minute exercise 33 After 3 minute exercise 38 After 4 minute exercise 40 After 5 minute exercise 44 108 132 152 160 176 After 1 minute recovery 112 After 2 minute recovery 96 After 3 minute recovery 88 After 4 minute recovery 19 76 After 5 minute recovery 19 76 (30 minutes activity) Group 1: The person would have a lower heart rate in which it would have increased slower and then decreased faster than group 2, and also much fitter. Group 1 results (Averages): Exercise duration Average Heart rates (30 Minis exercise) Resting pulse rate: 75 1 Minute exercise: 135 2 Minute exercise: 148 3 Minute exercise: 152 4 Minute exercise. 152 5 Minute exercise: 154 1 Minute recovery . 103 2 Minute recovery: 94 3 Minute recovery: 87 4 Minute recovery: 81 5 Minute recovery: 76 (No activity) Group 2: The person would have a much higher heart rate than group 1, not fit and likely to be normal obese (Weight). Group 2 results (Average): The results recorded in the heart rates were average to an average student. The results were similar. The differences had shown the fitness level. (The lower the heart rate the fitter, The higher the less fitter. The results recorded in the heart rates were higher than a frequent swimmer. The results were different than an average swimmer. Discussion: When exercise is conducted, Cells are forced to work harder in which, the cells will then need nutrients faster. When blood is pumped from the heart it travels to the lungs to get oxygen (oxygenated blood), then to the cells therefore cells will need nutrients faster so this process speeds up. The results were expected; every minute the average heart rate increased by at least 10 beats, however the heart rates went down roughly the same speed than when exercising.

Audiometry Lab Report Example | Topics and Well Written Essays - 500 words - 1

Audiometry - Lab Report Example The conduction testing of the air presents stimuli to both ears but independently using some special earphones. The stimuli is reduced while going from the test ear to the cochlea of the others ear. This is energy loss is known as the interaural attenuation which ranges between 45 – 80 dB. However, stimulation occurs to the cochlea in both ears. As a result, cross hearing is a situation to consider more in the conduction of bone than in the conduction of air (Yoon et.al 469). The mastoid process of the proper ear is used to transmit pure tones by placing vibrator bone over it. The results of the experiment may be determined by the placement of the vibrator as well as the pressure. Technical factors and distortion may cause may limit the output of the audiometer to about 80 dB. The non-test ear should always be eliminated from the procedure whenever the cross hearing is suspected. In order to remove the non-test ear from the procedure in case of any suspected cross hearing, is to mask by delivering noise to the non-test ear (Yoon et.al 469). The loudness of the masking procedure should be able to prevent the tone reaching the non-test ear and stimulating it. This experiment aims at determining the threshold hearing over a variation of frequencies. The experiment may test the bone conduction also known as the vibrator as well as the air conduction or the loudspeaker. But the audiometer can only test the air conduction also known as the loudspeaker. The procedure of performing the experiment was the same for two different partners. The first thing was to check and confirm that the connection of the audiometer and the headphones was not loose. The experiment was conducted in a silent laboratory. My partner put on the headphones while I adjusted the volume of the audiometer over the required frequencies. The hearing threshold was determined for every frequency. The button was used to

Using social media in business opportunity and risk (Facebook) Personal Statement

Using social media in business opportunity and risk (Facebook) - Personal Statement Example Forums for interactions that the media, such as Facebook, offer allow organizations to understand their customers need and to tailor their products for meeting these needs. It also helps in identification of markets that aid sales and market control. Availability of a pool of customers or potential customers, cost efficiency and cost effectiveness are some of the opportunities that Facebook offer to corporate organizations. Cost effectiveness of Facebook, for instance, while it ensures effective access to target audience, in strategies such as marketing and customer relationship management, facilitate the profit motive. Facebook also allows a business an opportunity to collaborate with other businesses for common interests and this is possible through interactions in professional groups (Belleghem 191). Reliance on social media such as Facebook however reduces interactions with customers for in-depth communications and this may be a barrier to understanding and meeting customers’ needs. There is also risk of insecurity over data because of sharing of information on Facebook. In addition, technicalities with the media, such as when it shut down, may impose temporary limits to information access (Payne & Frow 388; Belleghem

Role of ICT in Science Education

Role of ICT in Science Education What is the role of ICT in Nature of science and science teaching and learning? To answer this question, we need to understand what modern IT systems (both hardware and software) are good at Collecting and storing large amounts of data Performing complex calculations on stored data Rapidly processing large amount of data and Displaying it in variety of ways helping to present and communicate ideas. All these answers have direct relevance to the process of education and these help us to address an important question of when to use ICT? Before we discuss how ICT enhances the science education, we will see what activities involve in school science. The science particularly school science involves lot of practical activities. It includes observing, measuring, communicating, discussing, investigating, handling, watching, monitoring and recording the results. On the other hand science is equally a theoretical subject. It involves thinking, inferring and having god ideas, hypothesising, theorising, simulating and modelling. ICT can help as much in this aspect of science and in same way they do in practical aspect. In the mean time science teachers should use ICT along with their professional skills during lesson to maximise its potential. There are ranges of software tools available to science education such as Interactive White Board, Simulations, Data logging, Spreadsheets, Word processing, Virtual Learning Environment, Desktop Publication etc. Out of these, I will concentrate on Interactive white board and how it enhances the science education. What is Interactive White Board? It is a large physical display panel that can function as an ordinary white board, a projector screen, an electronic copy board or as a computer projector screen on which computer image can be controlled by touching or writing on the surface of the panel instead of using mouse or keyboard. Smith et al (2005) introduced the term Pedagogic interactivity within the use of interactive white board. Jones and Tanner (2002) related this term to Interactive teaching where teachers use higher order questioning skills that make student active contribution towards discussion and their views are valued. Also the teachers used their opinion to test their understanding against particular topic. Taber (2003) found that teacher role is critical in structuring activity in ways that challenge and build upon pupils prior knowledge white integrating new scientific ideas. Introducing IWB, can make learners interactive with whole class teaching gives new opportunity for them to express their ideas. These are not only done verbally, but using graphical and other representations. It helps them to share their scientific ideas with whole class and get back the teachers and peer feedback. Rogoff (1990) explained that the introduction of IWB in school environment provides a dynamic and manipulate object of joint reference which offers new forms of support for inter subjectivity. This is a form of socially shared cognition which facilitates explicitation and exchange of ideas and negotiation of new meanings in accordance with others perspectives. The use of IWB is not only develops the teaching styling. It also helps to enhance teacher efficiency. To make this happen, teachers should understand the potential contributions of ICT in teaching and learning. There are different types of learning involved in science. Underwood (1994) explained that the primary responsibility of the teacher is to encourage the cognitive development of the child, to ensure the retention, understanding and active use of skills and knowledge. Lee (2006) and Winzenreid (2007) found that the effects brought to the classroom IWB can be completing transformational or not change at all. All it depends upon how best the system is implemented and how it is used by the teachers to enhance the students learning. Mortime and Scott (2003) explained the teachers role who acts as mediation between the IWB and the students. The full understanding of technical interactivity is an integral part of this. In Science, interactive communication is vital between students and teachers to explore ideas together, drawing own hypothesis, discussing recent socio-scientific issues, consolidate scientific and informal ideas. The IWB contributes to the flow of interactive communication. Godwin and Sutherland (2004) described how teachers represented their individual constructed knowledge in order to develop student common understanding. Thus the IWB plays a vital role in science education. But how active the pupils are learning? The answer is how far the teachers understand and implement the technology successfully and careful blending of technology and pedagogy. On the other hand Hargreaves et al (2003) found that the class with non-technology context raised some issues. The issue such as higher lesson pace, collaboration and participation in discussion, assessing pupil knowledge, all these shown that the technology interactivity is highly helpful. Thus the teachers understand the features of IWB those associated with pace, motivation, involvement, participation and collaboration. (Becta 2003). But Moss Et al(2007) argued that this is not sufficient to develop students learning. But Hepper (2004) argued that the IWB provides teachers an opportunity to teach in their own professional way with a central focus of aboard, but with the excitement of media rich content. Thus it does not collide with existing pedagogy practice. Nieder Hauser and Stoddart (2001) and Olson (2000) found the choices of technology by teachers are based on their own conception of teaching and learning. Hennessey etal (2005), Kerr (1991) accepted the above argument that introducing new technology does not produce radical pedagogical change. Instead a slow evolutionary process where these new powerful tools interact slowly with existing particles. Roger and Finlayson (2004) demonstrated that whole class teaching with technology in science forced to use computer for demonstration with little manipulation by pupils. In Science the understanding of skills and concepts by students depend upon the facts and information provided by teachers. Clearly IWB provides number of ways of providing this knowledge. How much the students understanding of science is improved by using ICT? impact 2 Project (Harrison et al 2002) found that the use of ICAT has a measurable impact on the performance of students studying science in the secondary school. ICT is just the learning tool just it does not ensure learning. The most importance is application skills; which improves students understanding. Operational skills cannot be ignored, but teachers should make sure that this should not predominate over application skills. For the science teacher, an important aspect of application skill resides in the investment in task design, target setting and intervention strategies. An optimistic view is that school laboratories, like classrooms, will continue to be places where people meet and exchange ideas. Social interaction, discussion and hands-on activity are vital aspects of the educative process that are inadequately satisfied by the solitude of individual computer use. Computers should not be allowed to displace essential intellectual exchanges between people but should be used in ways that amplify and complement them. Thus it is important to identify and understand both the benefits and the disadvantages of individual ICT tools, so that judgements about fitness for purpose can be made at every stage of planning. The preparation of students for a task, the definition of task objectives and the nature of teacher interventions all contribute to the quality of the outcomes. These factors need to be borne in mind as we consider the possible impact of some of the innovations. ICT is transforming all aspects of society: its institutions, commerce, industry, home life and education. In education, there is a growing assumption that using computers is a good thing; after all, the response of many students seems to be predominantly one of high motivation. There is, however, a certain risk that the educational rationale for ICT becomes overshadowed by the glamour and progress of the hardware and software technology. Undoubtedly, technological developments will continue to invite thinking about new opportunities for teaching and learning, but it is very much easier to engage with the new technology than to seek a deep understanding of its implications for education. It is important, therefore, that pedagogy and technology are equal partners in the development process. In particular, innovations should not be driven by technology for its own sake. As guardians of pedagogy, teachers have a significant role in shaping the use of ICT for learning. The future success of ICT in science rests on the quality of thought given to its use, with a clear focus on learning outcomes.

Non-Traditional Sports: Social Barriers :: Bodybuilding Synchronized Swimming Essays

Non-Traditional Sports: Social Barriers Gender barriers have always existed in the field of sports. I will be focusing specifically on women in the field of bodybuilding and men who enter synchronized swimming in order to illustrate the social and cultural costs and benefits of these individuals entering their given sports. Breaking Barriers: The gym is the world of gods and heroes, goddesses larger than life, a place of incantations where our bodies inflate and we shuffle off our out-of-gym bodies like discarded skins and walk about transformed. . . . Here, in this space, we begin to grow, to change. The transformation has begun, and our flawed humanity is falling off fast. We are picking up our shoulders, elevating our chins, shaking ugliness from our shoulders with a series of strokes, the glistening dumbbells, listening to our blood's rush. Our pasty misshapen bodies are developing clean lines. Our day's tribute of trials and heartaches is fading, for here, in this gym space, we become kings and queens. Larger, invincible, gods in ourselves. (Introduction, Bodymakers: A Cultural Anatomy of Women's Body Building) Women in bodybuilding is a recent phenomenon. It is an example of the cultural transformation and revolution that has been in the process for many years now. Leslie Heywood, the author of the quote above, is an assistant professor of English at the State University of New York, Binghamton. As stated by a critic of her recent book, Bodymakers, "Heywood looks at the sport and image of female body building as a metaphor for how women fare in our current political and cultural climate. Drawing on contemporary feminist and cultural theory as well as her own involvement in the sport, she argues that the movement in women's bodybuilding from small, delicate bodies to large powerful ones and back again is directly connected to progress and backlash within the abortion debate, the ongoing struggle for race and gender equality, and the struggle to define "feminism" in the context of the nineties. She discusses female bodybuilding as activism, as an often effective response to abuse, race and m asculinity in body building, and the contradictory ways that photographers treat female bodybuilders." It is evident from this brief yet descriptive narration of her book that Heywood believes both cultural costs and benefits of women in the sport of bodybuilding exist, as well as in any other field in which women push the restraints of social acceptance.

Gattaca and Orwell’s 1984 compared Essay

Although the distopias of Orwell’s Oceania and Niccol’s not to distant American city are in many ways similar in the sense of totalitarianism. The systems of control are quit different. Orwell’s world seems to be an overbearing socialist police state where as, the world in Gattaca is almost total control by science. The two pieces were written decades apart from one another, but both the film and the novel send a clear message; to enjoy the social mobility and freedoms of modern life and to be aware of how fragile they are. Both Orwell’s and Niccol’s worlds are dependant upon a class or cast system to divide the powers and freedoms of the people in their respective worlds. Oceania as far as we can tell has three maybe four classes. The Proles are the group of people who hold the worst of the jobs within Oceania. They work as laborers and as prostitutes but their idle time is spent like many undergrads in the modern world; listening to music, drinking beer, and fornicating. The second and arguably the lowliest of Orwell’s classes is the outer party, to which our main character Winston is a member. The outer party is subjected to all the evils of the inner party. Their inner most personal thoughts and feelings are monitored by the thought police and even the slightest inclination of disloyalty is punished by being vaporized. They work mostly as desk jockeys, and their free time is to be spent doing activities for the party. The inner party is closely related to an upper management class within a perverted militant socialist world where all business is run by the state. Compared to the outer party the inner party does seem to enjoy a few more modern comforts but, they are still being subjected to tellascreens and thought police. Arguably the fourth class would only consist of one man a ruling dictator who goes by the name of Big Brother his existence is questionable but if he were to exist it is presumable that he would enjoy every possible comfort. Gattaca has a class system as well but, it is a much simpler one controlled by science. Depending upon Gene manipulation a citizen is either a valid or they are an invalid. The days discrimination because of race, religion, or  sexuality are gone, in this world all that matters is the results of a blood test. The lead character portrayed by Ethan Hawk is Vincent/Jerome Morrow. He is what they call a faith birth, his parents conceived him in the traditional way, in the back of a Chevy Rivera. At his birth he did have ten fingers and ten toes but now that’s not all that mattered. After testing one drop of blood the doctors new that he had a 60% probability of having a neurological condition, 42% probability of manic depression, 89% probability of attention deficit disorder, and a 99% probability of having a heart disorder his life expectance only 30.2 years. Vincent, an invalid, was condemned at birth to live a short life of turmoil. These two very rigid and well structured societies whose purpose was to create order over universal individual freedoms for its citizens freewill was not something that was desired. What Vincent and Winston have in common his that they used their freewill and determinations to resist the status quo.
