Lab Protocols
Through trial and error my class and I have learned that screwing around and misbehaveing in lab not only results in multiple page papers, but can also be harmful, dangerous, and costly to our teacher and school.
There are many rules or "protocols" that should be followed in a lab enviroment. In this situation there are ten basic rules that must be followed at all times while participating in lab experiments. These are here for our own safety and should be followed for this reason.
The first rule is that everyone in the lab should wear eye protection.
In a lab enviroment eye injury is very common. Eye protection greatly reduces this risk of injury.
The second is no horseplay. Horseplay can cause injury to yourself others and can cause damage to the laboraty.
The third rule is that you should only interact with your partner and the teacher. This will prevent distraction from your set experiment.
The fourth rule is that you should not leave your experiment unattended whether you think it is dangerous or not. This rule is completely self explanatory for safety purposes.
The fifth rule is to be extremely careful with equipment. Not only for money purposes but also for your own personal safety.
The sixth rule is to not touch anything that the teacher or the lab specifically instructs you to. Because you don't need to.
The seventh rule states that activities should only be done if they are specifically discussed in your lab. This is for safety purposes and for the liability of the school.
The eighth rule is that you are not to contaminate chemicals by using equipment in more than one substance without washing it thoroughly. Doing this can cause explosion, fire, bodily harm, poisonous gasses, or possibly death.
Also do not return chemicals to the original container after they have been used.
The ninth rule is that you must read your lab handout thoroughly before experimenting in a lab environment. It is a good idea to ask any necessary pertinent questions prior to partaking in your lab. Follow directions exactly.
This is to prevent possible harmful mistakes that may result in death, poisonous gasses, bodily harm , explosion , or fire.
Last but not least the tenth rule is that before taking leave of the
Ira Berlin wrote Generations of Captivity to persuade to his readers that even as time passed between the generations the change from a society of slaves to a slave society was one that happened slowly over time. Berlin wrote the book in five different sections, each one showing a focus of slavery from the more focused areas, like the Chesapeake Bay, to areas that were less focused with slavery. Berlins first chapter of the book dealt with the Charter Generation, which maintained the idea of a society with slaves, within the 1600s respectively. Berlins second chapter moved on to the Plantation Generation, which showed the society moving closer to the slave society. The third chapter focused on the Revolutionary Generation, which was a slave
First, she explored the history of slavery and affection of it, which started from captivity. She was not convincing her reader but introduce people into the history of the old South region. She uses many detail of war as example to give her readers an image of the time. Readers would understand the link between warfare and taking captives into the Natives communities. She started at the point which colonies had not found the South, and tried to explain the exercise of slavery in the region. Before the colonies arrived, people on the South formed villages and they fought against each other for resources and food. People who have been captured in the war are captive or war prisoner. Snyder stated “captives usually arrived in Native communities as prisoners of war or as chattel via trade. Still others came voluntarily…hoping that their captors would choose to adopt them” (5) and slavery is a kind of captive. She pointed out that captive and slavery had existed long before the colonies arrived. She explained captive was a form of slave in war, which points out that slavery exist before the Colonies arrived. She said in the b...
In “Happiness and Its Discontents” Daniel M.Haybron describes the relationship between pain and happiness. Put simply, pain doesn 't bring happiness,happiness comes from within.
During the 18th and 19th century slavery became a thriving concept in the United States, especially in the south due to the rapid expansion of the cotton industry. Many stories told through the grapevines that have all impacted those who listen to the trials and tribulations these slaves took on during this time in the United States. However there are certain individuals who have the ability to give you a perspective of slavery that some could not achieve. Frederick Douglass, a well knowledgeable freed African American gives the insight to slavery in his own narrative. In the Narrative of the Life of Frederick Douglass, Frederick reveals the truths behind slaves’ lives, the culture of slavery, as well as the psychological struggles these American slaves endured during this time period.
...nineteenth century. Douglass was given some education and worked on it by himself after lessons ceased. Slaves who had any education were a rarity in the south. By taking away any opportunity for a better life, slave holders controlled every aspect of a slave’s life. However, after some education, Frederick longed for a life out of slavery. He realized he not only had to have a sound mind, but also a sound body and soul. The will to leave his old life behind was as important to education in obtaining his freedom. Frederick had many experiences that coincided with the average life of a southern slave during his time in captivity. However, after his escape, his life was very different from slaves who had obtained freedom by some means. Frederick Douglass became one the most prominent men in his time due to his hard work and determination he gained from being a slave.
... book also shows how even a man who has been beaten, starved and “broken in body, mind and soul” can rise from slavery and fight back. Douglass goes through many awful events as a slave, but once he finds that reading is the way to freedom his life is changed forever. He continually is filled with the want to escape slavery and even goes as far as to fight one of his masters in an event Douglass calls “the turning point in (his) career as a slave” On September 3rd, 1838 Frederick Douglass was a free man. Although little is said about his escape from slavery, he tells us not only of how it felt to finally be free but also gives us some details on what it was like to be free for the first time, not trusting anyone and feeling paranoid that at any time he may be caught , and then slowly becoming accepting of the help offered to him and making a new life for himself.
For centuries scientists have used animals to study the causes of diseases; to test drugs, vaccines and surgical techniques; and to evaluate the safety of chemicals used in pesticides, cosmetics and other products. However, many scientists amongst animal- right activists forbid the use of animals in scientific research regardless how many illnesses are eliminated through the use of animals in scientific research. Amongst animal right activists, David Suzuki also raises concerns towards animal experimentation. In his article, The Pain of Animals, Suzuki argues that humans have no right to exploit animals because--much like humans--animals also experience pain. In contrast to Suzuki, Haldane, in his article, Some Enemies of Science, argues because animals are very similar to humans, scientists have no choice but to use animals in scientific experiments. Both authors greatly contrast their opinions towards animal experimentation; however Haldane has a more explanatory approach towards animal experimentation. He argues animal experimentation should be acceptable because other forms of animal exploitation are acceptable in society. Secondly, unlike other forms of exploitation which seek pleasure in killing animals such as leisure sport, scientists, most likely do not harm animals; if pain is intended on an animal it is strictly for the purpose of scientific advancement. Thirdly, although, animal experimentation may cause some extinction, it is only one of many other causes of extinction, if other causes are not condemned; then neither should animal experiment...
This theme song to a popular cartoon is a farce dealing with experiments carried out on animals. In the cartoon one mouse is made very smart and wants to take over the world while the other is clearly not as smart. While the cartoon makes jokes, the reality is that mice and other animals re being used for medical tests every day. For some people this testing brings up ethical questions. One of the biggest questions: is it really necessary to take the lives of animals in the name of science and for the betterment of humanity? For animal rights activists, like People for the Ethical Treatment of Animals (PETA), the answer is no. PETA pressures labs into halting experiments because they believe that animals are not to be used by humans for "food, clothing, entertainment, or to experiment on" (People for the Ethical Treatment of Animals 1). Its stance is that any testing is painful, inhumane, and unnecessary when alternatives are available. The PETA website says that "animals, like humans, have interests that cannot be sacrificed or traded away simply because it might benefit others." (People for the Ethical Treatment of Animals 2-3). Essentially, PETA is of the opinion that animals and humans should have identical rights. In their press releases PETA puts out pictures of rabbits with open flesh wounds and dogs with rashes on their skins--all in an attempt to disgust people into sympathy for their cause. In actuality the number of lab animals used has been cut in half in the last 25 years (James-Enger 254). Of the animals used, 90 percent are rats and mice (James-Enger 1). Moreover, 11 million animals die each year in animal shelters (Americans for Medical Progress 2) and an astounding 95 percent ...
Everyday scientists perform different tests on cells (known as in vitro testing) to assess numerous concepts, such as drug efficiency and nanoparticle toxicity. Unfortunately, these tests do not always provide the best or most accurate results since the human body is composed of several different cell types, all of which interact and cause robust responses that cannot accurately be mimicked or studied with single cells. Thus, current techniques are being employed to imitate the complexity of the human body by using more than two cell lines combined together.
In addition, discrimination by appearance is really unfair to job-seekers, who do not get hired. My brother, who is Hispanic, has many visible tattoos all over his body. Each and every one of his tattoos mean something very special to him. If someone saw my brother and his tattoos, immediately, they would think he is rebellious. He is a genuine, intelligent person,
Because of animal experimentation, scientists are able to advance in medicine and find cures and treatments, but all this must pay a prize. Animals in these experiments suffer and even die for the cause. Many argue that it is inhumane and cruel. Others would argue that animal experimentation is beneficial and necessary. The viewpoints between Jane Goodall and Dario Ringach are different when it comes to animal testing, but they’re after the same goal: caring for the animals and wanting to look for cures and treatments.
For years now people have been using animal experimentation to create new ways to help save the human race. There are people who believe that it does help, and that it is necessary to continue, while others oppose and want to fight for the elimination of animal experimentation. Scientists fight for the cures needed to help man kind, but struggle to do so as people fight against their work in progress. But as Jennifer A. Hurley stated, “History has already shown that animal experimentation is not essential to medical progress.” Stuart W.G. Derbyshire believes “The best hopes to treat or cure any number of diseases all rely in the current animal experiments.” Both sides have evidence that can allow both to be proven correct. But there are negative arguments that can prove the other wise. The real question to ask is, Does animal experimentation really help advance medical research?
forms of suffering. As we grow older, we learn that certain things that we want may involve some pain. For example, goals need some type of action in order to be attained. Schopenhauer says that humans experience pain in everything, such as performing routines, we become enslaved to them. Schopenhauer view of life is constructed in an optimistic way. He believes that human life is not a wonderful thing because it brings pain into our lives. He emphasizes this reality by pointing out that it does not benefit humans to suffer.
for the use of animals in research. This has attempted to slow or halt the work
There are some laws that have been passed to protect animals like the Act of 1986 which makes sure animals suffer as little as possible; and the Cruelty to Animals Act which was passed in 1876 (Franklin). People are making an effort to save as many animals as possible when trying to experiment. Animal experimentation may be very harmful to animals and inhumane, but it is the only thing right now that is helping to discover new medical advances. Animal experimentation has been used to save many people’s lives and other animal lives. There are many negatives to animal experimentation, such as the cost and the treatment of the animals.
