Roly Poly Lab - Free Essay Example

Pillbug â€Å"Roly-Poly† Behavior LaB ? Purpose: The purpose of this lab is to observe the behavior of the Armadillium vulgare (roly- poly bug), as well as hypothesize whether it will be attracted to, repelled by, or unresponsive to certain substances. Methods 1. Observing the pillbug: examine the pillbug’s shell and body, shell shape, color, texture, number of legs, number of antennae, motion, speed, and sex after close examination. 2. Formulate hypotheses: choose substances (powders and liquids) and suggest whether the pillbug will be attracted to, repelled by, or unresponsive to each substance. . Perform an experiment: using a control, test the pillbug’s reaction to the substances 4. Compare with classmates: determine whether classmates had similar results when testing the same substance. Data Collected ? The pill bugs have 7 pairs of legs with 14 overlapping plates. Oval-shaped like a â€Å"pill†. One pair of antennae. Black with lighter spots. The pil lbugs climb over each other. The male pillbugs are bigger and darker 3 female pillbugs. Male plays dead on his back when tampered with. The pillbugs roll into a ball for safety. Uropods at the end of abdomen. Legs move in a quick wave-like motion. ? 1. As the pillbug moves around in the beaker, the movement of the legs is very quick and fluid; similar to that of a â€Å"wave†. 2. To protect itself from predators, the pillbug rolls itself into an armored ball. Similarly, the pillbug uses its hard exoskeleton as a way to protect itself from the elements. Their long antennae allow for them to locate food and their shorter legs in the front help to bring the closer food to their mouths. Lastly, the pillbug’s multiple legs allows for it to interact with the environment. 3. When allowed to crawl on my hand, the pillbug moved quickly in a zig-zag motion. I could feel the pillbug as it made it’s way up my arm. After close examination, I later discovered that the pillbug was able to cling to my skin because of it’s hook-like tips on it’s legs. 4. When the beaker is slightly tilted, the pillbugs prefer to move forward toward the top of the beaker. Next, we measured the speed and distance of each pillbug. The results can be seen in the table below. The next step was to formulate hypotheses about the pillbug’s reaction to common powders and liquids. The next part of the lab was to then test the pillbug’s reaction to the chosen substances and determine whether or not the hypotheses in Table 1. 3 were supported in this experiment. The control in this experiment was water. The final procedure in the lab was to compare our results with the results of our classmates who tested the same substances. The results can be seen below in Table 1. 5. ? Key: + = towards; = repelled ; 0 = no reaction Summary/Conclusions This experiment demonstrates that pillbugs prefer a wet environment to a dry one. Through our data, we have concluded that our hypothesis, â€Å"if the pillbug is exposed to water, then it will be responsive and move toward it† , is correct. Even so, we also hypothesized that, â€Å"if the pillbug is exposed to milk, then it will be responsive and move toward it†; this, however, was proven incorrect after we performed the experiment. On the other hand, several other groups also tested the pillbug’s reaction to milk and found that the pillbug moves toward it. To better improve this experiment, we would make sure that there is no trace of water in the path of the pillbugs when we test the other substances. Factors that could have possibly altered the results in the experiment would be the age and gender of the pillbugs. PILLBUG â€Å"ROLY-POLY† LAB REVIEW QUESTIONS: A theory is more comprehensive than a conclusion. A hypothesis is a tentative explanation of observed phenomena. Data is the information scientists collect while doing experiments and making obser vations. After experiments and observations comes the conclusion. A control is a sample that foes through all the steps of an experiment and does not contain the factor being tested. Yes, data can prove a hypothesis to be true. Conclusion Scientific Theory A pillbug has 14 body divisions If a pillbug curls into a ball, it can be concluded that it feels threatened. Pillbugs that back away from a substance are repelled by the substance. THOUGHT QUESTIONS: 1. A scientific theory is a concept that ties together many varied conclusions into a generalized statement. 2. It is important to use one substance at a time when testing a pillbug’s reaction because in this experiment we are trying to determine whether or not the pillbug is repelled by, attracted to, or unresponsive to a specific substance. If you use more than one substance at a time, it will not determine whether the pillbug is attracted to, repelled by, or unresponsive to a substance, especially if the pillbug is al ready headed towards the direction of a substance. 3. No, the scientific method cannot explain all observations. In order for the scientific method to explain all observations, it must be able to answer a question about something that can be measured. The question: Do pillbugs have a color preference ? cannot be tested by the scientific method. METRIC MEASUREMENTS MICROSCOPY REVIEW QUESTIONS: 1. 11 mm equals 1. 1 cm 2. 50 mm equals 0. 95 m 3. 2. 1 liters equals 2100 ml 4. 122 °F equals 50 ° C 5. 4. 100 mg equals 0. 0041 g THOUGHT QUESTIONS: 19. Locating an object is more difficult if you start with the high-power objective rather than the low-power because the high-power objective is used to get a closer study of an object/specimen, whereas the low-power objective is used to quickly scan and LOCATE something smaller in a large area. 20. The advantages that the metric system provides over the English units of measure is that all conversions, whether for volume, mass(weight), or length, can be in units of ten. 21. Scanning power objective allows you to observe the greatest number of cells within the field of view.

Research Paper review on â€Å"Improvement of Manufacturing Operations through a Lean Management Approach: A Case Study in the Pharmaceutical Industry† This is a review on the research paper â€Å"Improvement of Manufacturing Operations through a Lean Management Approach: A Case Study in the Pharmaceutical Industry† by Maria Elena Nenni, Luca Giustiniano and Luca Pirolo submitted to University of Naples Federico and University LUISS Guido Carli Abstract: At the current situation, Lean Manufacturing has turned into an overall marvel. It is entirely effective in drawing the consideration of organizations of all sizes. An extensive number of organizations are taking after Lean advancements and encountering unlimited upgrades in quality, production, customer service etc. According to lean principles, any use of resources that does not deliver consumer value is a target for change or elimination. It also refers to the elimination of non-value adding/wastes. This Lean approach has mainly been applied in manufacturing, notably in Toyota, and the Toyota Production System, from where Lean originates in the early 1960’s but not to a complete extent. However, lean has also been widely applied in non-manufacturing areas. ‘Lean Management’, or rather ‘Lean production’ is considered to be a smart approach on a system of measures and methodologies.

Pete Rose3 Essay Example For Students

Pete Rose3 Essay Bart Giamattis decision to ban Pete Rose from the Baseball Hall of Fame was not a fair decision at all. Pete Rose was placed on Baseballs ineligible list in 1989 when commissioner of baseball, Bart Giamatti concluded that Rose had bet on baseball games, including games involving his own team, the Cincinnati Reds. In an agreement made with Baseball, Rose accepted his banishment from the sport. Although he never admitted to having gambled on baseball games(McCarver 44). Pete Rose was a phenomenal baseball player and manager. He was accused of gambling. His team while he was managing was supposedly involved. Bart Giamattis severe punishment of Pete Rose is a very controversial topic in the world of sports. There are a few rules that must have been followed to be inducted to the Hall of Fame. The one that is keeping Rose away is rule five. Rule five states: Voting shall be based upon the players record, playing ability, integrity, sportsmanship, character, and contributions to the team or teams on which the player played (Hemmer 85). This rule has been tested and beaten many times. Many players have entered the Baseball Hall of Fame such as the very unllikeable Ty Cobb, the drinking Babe Ruth, the umpire abusing John McGraw, the racist Cap Anson, Gaylord Perry a suspected cheater, and the gambling Leo Durocher. Those are just a few of the baseball players who somehow made into the Hall of Fame and got passed rule five (Will 225). Pete Roses problem was not even as severe as all of these other men. The argument to this is that if these men can make it into the Hall of Fame why is Pete Rose banned. It is obvious that these players made it there with just their playing abilities and not by all of the other characteristics needed to be inducted into the Hall of Fame (Will 226). Pete Rose started playing professional baseball in 1960 in the minor leagues and by 1963 he reached the Major Leagues as a rookie second baseman with the National Leagues Cincinnati Reds. Rose won the National Leagues Rookie of the Year Award for 1963. He spent most of his 24 year career playing with the Reds, Rose also played with the Phillies and the Expos. In 1985 Rose broke one of the most unbreakable records of all time, by passing out Ty Cobb for the most career hits ever (US fans n.p.). Rose holds many records, some of which are: most games played, most at bats, and most singles by a major league baseball player. All of these statistics are definitely Hall of Fame worthy (Cosmic baseball n.p.). Pete Rose denies that he ever bet on Major League baseball games. The commissioner of baseball, Bart Giamatti, did not believe Rose at all. There is not any kind of proof that directly led to Rose gambling. There is evidence that does lead to Rose gambling on games, even ones involving the Cincinnati Reds (Reston 32). This evidence came from three men who are former friends of Pete Rose. Tommy Gioiosa, Paul Janszen and Ron Peters were a group of bodybuilders in a local gym in Cincinnati. All three of them used steroids to make themselves physically big (Allen 158). Gioiosa, Janszen, and Peters each was convicted of felonies. They were all involved in illegal gambling, drug dealing (cocaine and steroids), and income tax evasion. Pete Rose knew what kind of men these three were and broke away from them.It is possible that these three men could have turned Rose in for some kind of pay back, because of the fact that Rose stopped associating with them (Allen 160). How reliable are these men and their information about Rose?Pete Rose met Tommy Gioiosa in Florida in 1978. The two of these men became good friends. Gioiosa moved to Cincinnati and lived with Rose and his family that year.Tommy Gioiosa introduced Rose to the group of bodybuilders at the local Cincinnati gym. Among this group was the gyms owner Mike Fry, and a bodybuilder Donald Stenger. Donald Stenger was a big supporter of steroids. Tommy Gioiosa really bulked himself up with steroids that he got from Stenger (Reston 58).

Osteopathy free essay sample

More than forty-five percent of all osteopathic physicians are general practitioners or family doctors. As with medical doctors, osteopaths have office practices and work in hospitals. About fifteen percent of all osteopathic physicians are specialists in such fields as surgery, obstetrics and gynecology, pediatrics, psychiatry, neurology, and internal medicine. A small number of osteopathic physicians have salaried positions in osteopathic hospitals and colleges, private industry, and government agencies. In order to be an osteopath you are required to go through extensive training. Osteopathic medical education requires 4 years of fulltime, comprehensive, and complete medical education. Once graduated and having attained the D. O. degree (Doctor of Osteopathy) prior to being eligible to practice, the osteopathic physician must complete a further 2 to 5 years of fulltime residency training in the specialty of their choosing such as internal medicine and subspecialties, surgery and subspecialties, orthopedics, pediatrics, obstetrics and gynecology, emergency medicine, psychiatry, dermatology, pathology, family medicine, or musculoskeletal medicine (manual therapy osteopathy). We will write a custom essay sample on Osteopathy or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page There are 18 certifying boards with 85 specialties and subspecialties. Upon completion of residency training, specialty certification examinations are required. Even after the required education and training osteopaths still attend education courses so that they can be updated on all of the current techniques that could be used for different situations. Osteopaths are required certain skills that will enable them to do their job efficiently and excellently. Osteopaths firstly need to have a great nowledge of the human anatomy, so that they know where everything should be and how one ailment could also be affecting another part of the body. Listening skills are very important when pursuing a career as osteopaths. This will be used to determine or diagnose what is causing the illness or disease and would also guide them in using the proper treatment. Effective communication skills are essential to interact properly with patients. Osteopaths need to explain things clearly to patients mo re especially the  treatment procedures that will be used. They should know how to make the patient comfortable since they would be using sense of touch to diagnose and treat health problems. This is the reason they need to also have excellent eye-hand coordination. They need to be sensitive and patient. It will be helpful if they enjoy caring for other people. They need to be keen to details especially when reviewing the patient’s medical history. An osteopath will typically practice their skills in a clinic in the beginning of their career in order hone their skills while being supervised by an experienced osteopath. This is only optional, but it is very helpful for their career. An osteopath has many duties and responsibilities that they have to do during their day. Their duties include having to organize and keep their clients personal information. You will have to be able to diagnose and treat the ailment or disease that is affecting their client by relying on medical as well as surgical modalities. Osteopaths will correct disorders and afflictions of bones, muscles, nerves, and other body systems by medicinal and surgical procedures and, when deemed beneficial, manipulative therapy. Osteopaths will employ diagnostic images, drugs, and other aids to diagnose and treat bodily impairments. Some osteopaths will practice medical or surgical specialty. Since most osteopaths work privately their weekly hours will differ from others, but typically they work 40 to 50 hours a week. An osteopath does not have a lot of stress in their work environment. This is because they are mostly their own bosses as well as in control of their work hours and do not have any deadlines. An osteopath’s salary and wages depend on their experience, skill, as well s the amount of hours they work a week. The typical osteopath makes 90-140 dollars an hour. Since osteopaths can work in different environments such as government agencies, private practices and even from home; their hours will vary differently. On average an osteopath will make $160,000 annually. Although this can range from 90-170,000 dollars. After being an osteopath for a certain amount of years you could become an osteop ath university teacher. I picked osteopathy as my profession because it is the career that my mom has chosen. I wanted to do this because I never really understood how osteopathy worked or all of the stuff that she does. After researching this profession I am very interested in it because of the flexible schedule and the good pay. I think that the type of person that would be interested in this job would be a nice person that enjoys helping people as well as to be patient in order to put up with patients that are difficult to deal with. This person would have to be body smart as well as people smart. Thanks to career studies I have learned that this kind of job is probably not the best for me. I do not have the patience to deal with this job, as I am a doer according to career studies. In my types of intelligence sheet it says that I am not body smart and knowing the body is the most important aspect of being an osteopath. Also, for my career suggestion sheet it suggests that I do jobs that are outdoors and not jobs that have me inside for the entire day. After taking career studies I have found that the jobs that were suggested for me to take were jobs that I had already that of doing, such as fire fighter, police officer and zookeeper.

Equitable learning opportunities for children with disabilities

Equitable learning opportunities for children with disabilities Rochelle Standing 1081780For many years researchers have studied families of children with disabilities attempting to cast light on the important aspects and the complexities of providing equitable learning opportunities in education including the benefits and characteristics of working together in partnerships with parents and wh„ nau in terms their child's care and education. Collaborative parental partnerships are certainly not a new concept by any means however for parents of children with special needs it has presented a different set of challenges and perspectives which have many implications for educators. For the purpose of this paper I will explore what some of these are and discuss how they link with the role of the educator.Historically, Aotearoa/New Zealand has had a long history of acknowledging the involvement of families, particularly at the early childhood and elementary level, however it was not until the introduction of Tomorrow Schools (1989) and the Educati on Act (1989), that the emphasis of parental involvement in schools changed from a largely supportive role to one that was intended as a partnership (T.Caulcutt; personal communication; 15 July 2010; Harvard Family Research Project, 2006; Rodd, 2006; Wylie, 1999). According to O'Brien Ryba (2000) this was further exemplified with the introduction 'Special Education' policy in 1996. With an overall aim of providing learning opportunities of equal quality for all children the special education policy promotes the partnership between families, wh„ nau and education providers as being essential to the educational success of children with special needs (Wylie, 1999).The concept of parental partnership is something that has being discussed by researchers for some time however the common key elements that are suggested to reflect authentic partnerships are genuine power sharing, involvement and inclusion in all areas of the decision making process, and responsive, reciprocal and re spectful relationships...

10 - Assignment Example He uses the concept of acquisition of green card and undocumented migrants. American cultural imperialism for instance, has resulted into creation of a dominance culture that people from other countries admire to experience. Consequently, other cultures use unofficial strategies to gain access to the superior American culture for instance by marrying an individual from the dominant culture to obtain green card (DeCoy Gallerina 0:06). Gomez-Pena remains concerned about the plight and fate of the less dominant cultures that remain victimized of their strategies of accessing the dominant cultures. He challenges the officers who provide undocumented migrants access and the natives who marry aliens to help the latter in obtaining green Card. I became a border crosser when I violated the inherent immigration policies by gaining access to the country as an alien with non-residence status. In this class, I have crossed cultural borders especially frontiers off values and believe of other classmates from different countries.
