An Interactive Food Web Game for the Classroom

AÂ  food web diagram illustrates links among species in an ecosystem according to who eats what and shows how species depend on one another for survival. When studying an endangered species, scientists must learn about more than just one rare animal. They have to consider the animals entire food web in order to help protect it from the threat of extinction. In this classroom challenge, student scientists work together to simulate an endangered food web. By assuming the roles of linked organisms in an ecosystem, kids will actively observe interdependence and explore the repercussions of breaking vital links. Difficulty: Average Time Required: 45 minutes (one class period) Here's How Write the names of organisms from a food web diagram on note cards. If there are more students in the class than species, duplicate lower level species (there are generally more plants, insects, fungi, bacteria, and small animals in an ecosystem than large animals). Endangered species are assigned only one card each.Each student draws one organism card. Students announce their organisms to the class and discuss the roles they play within the ecosystem.One student with an endangered species card holds a ball of yarn. Using the food web diagram as a guide, this student will hold the end of the yarn and toss the ball to a classmate, explaining how the two organisms interact.The recipient of the ball will keep hold of the yarn strand and toss the ball to another student, explaining their connection. The yarn toss will continue until every student in the circle is holding at least one strand of yarn.When all organisms are connected, observe the complex web that has been formed by the yarn . Are there even more connections than students expected?Single out the endangered species (or the most critically endangered if there are more than one), and cut the yarn strand(s) that are being held by that student. This represents extinction. The species has been removed from the ecosystem forever.Discuss how the web collapses when the yarn is cut, and identify which species appear to be most affected. Speculate about what might happen to other species in the web when one organism goes extinct. For example, if the extinct animal was a predator, its prey may become overpopulated and deplete other organisms in the web. If the extinct animal was a prey species, then predators that relied on it for food may also go extinct. Tips Grade Level: 4 to 6 (ages 9 to 12)Examples of endangered species food webs: Sea Otter, Polar Bear, Pacific Salmon, Hawaiian Birds, and Atlantic Spotted DolphinBe ready to look up different species on the internet or in textbooks to answer questions about an organisms role in the ecosystem.Offer a large-sized food web diagram that all students can see (such as an overhead projector image), or pass out one food web diagram to each student for reference during the challenge.

Essay on The Role of Women in Marjane Satrapis Persepolis

Throughout Persepolis, Marjane Satrapi displays the vital role that the women around her have in developing her character and becoming the woman she is today. Women such as her mother, her grandmother, her school teachers, the maid, the neighbors, and even the guardians of the revolution influenced Marjane and caused her to develop into an independent, educated, and ambitious woman. Throughout the novel, Marjane never completely conforms or lets go of her roots, this is primarily due to the women who have influenced her. Marjane’s mother was one of the most influential people in her life, her mother taught her to be strong and independent. By introducing her mother through the story of her mother getting photographed at a†¦show more content†¦(7). Her grandmother also buys her books to help educate her on what is going on in their country (28). Both of these actions display that her grandmother wants her to be educated and also wants Marji to do whatever she desires and teaches her that she truly can be whatever she wishes. Before Marji leaves to go to Austria, her grandmother tells her â€Å"always keep your dignity and be true to yourself† (150). This is something that continually goes through Marji’s mind as she begins to make mistakes, being true to herself is something Marji is constantly struggling for and becomes a major theme throughout the novel. In the end of the novel Marji learns how to be true to herself and her ambitions as she divorces Reza and moves to Paris, which was an action heavily based on the ethics and teachings of her grandmother. Satrapi describes many other women throughout the novel who had an influence on her life and character as well. When she was young her maid, Mehri, fell in love with a neighbor but because she was not in his social class, the love was â€Å"impossible† as Marji’s father put it (37). This causes Marji to realize the despair social classes bring which leads Marji to her first demonstration and major act of rebellion (34-39).

Essay about Harm Caused by Steroids in the MLB - 756 Words

Opening day isn’t even here yet, and already we have enough controversy to last us the whole season. At a time when we’d much rather be thinking about the smell of fresh cut grass, hot dogs and pennant dreams, we’re forced to deal with a far darker issue. Now more than ever, there is alarming suspicion concerning apparent steroid drug use in Major League Baseball. As an avid baseball watcher and player of the game for twelve years this scandal is of great concern to me. In the time to come I will be informing you of how steroid use has tarnished baseball’s image, allowed for more records to be broken unfairly and the harmful effects it has on your body. Firstly, steroid use has tainted out national pastime and tarnished the game of†¦show more content†¦Secondly, using steroids has unfairly helped players smash records, making them huge stars. One of the biggest records broken was the single season home run record, by Mark Mcguire. Although he has not been accused of using steroids, he did admit to using a non steroid supplement that helped him unjustly break the record. The prior holder, the famous Yankee Roger Maris was dead at the time but his family did not want to see the record broken by a so called steroid user. Another famous player as of recent, Barry Bonds who has been the main player behind the current issue, is also in lieu of breaking a legendary record of the most homeruns in a career. Now the biggest star in baseball because of the eminency of breaking this record, do we consider it a fraud or fair play. Bonds is, at minimum a liar and a fool, and at worst, could go down as one of the biggest frauds ever. Lastly, although steroids have enhanced athletic performance unjustly, the adverse side effects can jeopardize your health. Steroids can cause serious health problems. Many changes take place inside the body and may not be noticed until it is too late. Some of the effects will go away w hen steroid use stops, but some may not.

Ethical Issues for IT Security for Network - myassignmenthelp

Question: Discuss about theEthical Issues for IT Security Personnelfor Network. Answer: Introduction The IT security personnel have great deal of power in terms of accessing information involving confidential data. Moreover, they can also access various information related to companies and individuals that ensure them with a great deal of power. Often seen that such power abused and therefore the need for the ethical issues springs up. Thus, the ethical issues that IT personnel face is mostly related to privacy. Identification of Ethical Issues The common ethical issues confronted by the IT security personnel is whether they should have the right to access the private email of the network users and monitor websites of network users. Then there is the ethical issue that involves whether the professional should install key loggers on the machine for capturing everything typed by the user. Moreover, certain trends observed that seem to raise the ethical issue in question (Steinbock, London Arras, 2013). The trends however involve the increasing dependency on computer systems for carrying out critical operations, dependency on networking advances and the internet for copying data from one location to another. Moreover, the advances in data analytics techniques that involves acquiring data from multiple sources. Code of Ethics for Analyzing the Issue There are certain professional codes of ethics designed for helping the IT personnel to ensure ethical business conduct. These codes of ethics not only describe the values of the company or organization ethically but also help in reflecting their mission. These codes meant to describe approaches to the employees for addressing different issues following particular standards (Whelan et al., 2014). However, the IT security personnel do not have a rule making body but they do have specialized professional organizations to dictate the codes of professional behavior. These organizations include Association of Information Technology Professionals (AITP), Cyber Security Institute (CSI), Independent Computer Consultants (ICCA), Information Systems Security Association (ISSA), Computing Technology Industry Association (Comp TIA) and Association for Computer Operations Management (AFCOM). The presence of these bodies thus acts as a reminder for the society to respect the existing code of ethics. These bodies are also empowered to impose sanctions in cases of any ethical violation. The bodies also promote corporate influence toward the interest of the specific group. Such interest usually involves reduction of competition through limitation, enhancing the difficulty of the function access, general price increment since they allow coordinated payment fixing in monopolistic way, promotion of the practice for special treatment and recognizing those that are specific activity dependent(Corey et al., 2014). There are various independent groups implementing the IT code of ethics. However, the guidelines include what the professional must abide by: The IT security personnel must strive to know themselves and be honest to the best of capability. The personnel must conduct the business in a way so that professionalism and integrity maintained. The personnel must respect ones privacy and confidentiality. The personnel must possess a high standard of knowledge and skill They should maintain a confidential relationship with the people they serve They should be able to build public reliance through their conduct and practice. Evaluation of Issues and Justification If one follows the formulated code of ethics, the IT security personnel need to follow then marking up the software and equipments while cost implementation is against the code of ethics as security personnel adopt dishonest means to carry out the business when should have been honest enough to perform at the best of their capacities (Pager, Holden Golenko, 2012). Kickbacks are form of negotiated bribery where a certain amount of bribe paid to the taker in return of the rendered services. In this case, there is a negotiation in the remuneration far ahead of time. Therefore, taking kickbacks from manufacturers would mean accepting a form of bribery on the part of the personnel that goes against the code of ethics. Moreover, it is also against the ethical norms of the IT personnel to accept commissions from the manufacturers for persuading clients for choosing their products (Inderst Ottaviani, 2012). The personnel should not forget that business should be in a manner where professio nalism and integrity maintained to the best of ability. Moreover, as per the code of ethics, the personnels should help build public reliance and not take undue advantage of their belief by misguiding them towards the company in which they hold stock with. The choice of products should be the clients call (Morrow et al., 2013). Conclusion The report discusses about the ethical issues of the IT security personnel. There is also discussion about the identification of the ethical issues and the various codes of ethics for the IT security personnel. Based on the questions there are few given questions analyzed and then justifications provided. References Corey, G., Corey, M. S., Corey, C., Callanan, P. (2014).
