Dissection Alternatives
Dissection in science classrooms is an experience that almost every student has to go through, but one that many will regret. It is estimated that six million vertebrate animals are dissected in high schools each year, and another 5.7 million are used in college laboratories. The issue of educational dissection has become a national concern. Many groups such as PETA and The Humane Society have been lobbying for years to outlaw such practices, and implement new and safe dissection alternatives. Alternatives to dissection have become more popular in recent decades and may be the future of modern science and education.
A dissection alternative is defined as an educational aid or teaching approach that replaces harmful animal use or compliments existing humane education. There are many types of alternatives available such as videos, CD-ROM activities, models, simulators, books, and interactive websites. The most commonly dissected vertebrate animals are fetal pigs, cats, and frogs, and therefore there are many alternatives available for these three animals. However, there are also alternatives for other animals such as sharks, rabbits, mice, snakes, minks, turtles, crayfish, clams, earthworms, starfish, and squid. Such alternatives are usually produced by educational companies or biological suppliers for student and teacher use. Science Works, Scholastic, Neotek, and Ventura Education Systems are a few examples of companies that make dissection alternatives for classroom use.
Educational dissection first received national attention in 1987 when a young girl named Jennifer Graham took a stand against it. She filed a lawsuit against her California High School because they demanded that she participate i...

...ts and teachers with free up to date dissection alternatives for middle school, high school, and college levels. The only cost is return postage, and anyone is eligible to obtain the materials. Another great program is the Educational Memorial Program. This is when animals are donated to veterinary schools when they have been euthanized because of a terminal illness, or died of natural causes. Such universities as Tufts University School of Medicine and Western Health Sciences University only use donated animal cadavers.
For many years dissection has been considered a widely used and acceptable form of scientific learning. Now, in the twenty first century, students are rebelling against such inhumane procedures. Because of the benefits to teachers, students, and school administrators, it is likely that dissection alternatives will be the future of modern science.
Earthquakes are best described as a shaking or vibration of the ground caused by breaking of rock. Sometimes they are very strong and other times you would hardly notice them. This shaking occurs when stress that builds up in the crust is suddenly released as the crust breaks free and/or slides against the other pieces of crust. Earthquakes may also be thought of as the breaking of a popsicle stick by applying pressure to both ends at the same time. Should you try this experiment , you will feel the pressure build up as you apply more force until the stick snaps. When the stick snaps you will feel an instant of pain at your fingers as the stress reduces and energy waves move throughout the stick. When the earth's crust is placed under similar types of stress, binding as the stress builds, it will also snap and release the energy into the surrounding rocks, 'ooch'. Thinking about earthquakes will become more clear if you try another experiment.
Earthquakes are a natural part of the Earth’s evolution. Scientific evidence leads many geologists to believe that all of the land on Earth was at one point in time connected. Because of plate tectonic movements or earthquakes, continental drift occurred separating the one massive piece of land in to the seven major continents today. Further evidence supports this theory, starting with the Mid-Atlantic ridge, a large mass of plate tectonics, which are increasing the size of the Atlantic Ocean while shrinking the Pacific. Some scientists believe that the major plate moveme...
The two important female characters in the "poetic tragedy"(Adler 12), A Streetcar Named Desire, are Stella and Blanche. The most obvious comparison between Stella and Blanche is that they are sisters, but this blood relationship suggests other similarities between the two women. They are both part of the final generation of a once aristocratic but now moribund family. Both manifest a great deal of culture and sensitivity, and because of this, both seem out of place in Elysian Fields. "Beauty is shipwrecked on the rock of the world's vulgarity" (Miller 45). Blanche, of course, is much more of an anachronism than Stella, who has for the most part adapted to the environment of Stanley Kowalski. Finally, both Stella and Blanche are or have been married. It is in their respective marriages that we can begin to trace the profound differences between these two sisters.
Throughout Tennessee William’s play “A Streetcar Named Desire,” Blanche Dubois exemplified several tragic flaws. She suffered from her haunting past; her inability to overcome; her desire to be someone else; and from the cruel, animalistic treatment she received from Stanley. Sadly, her sister Stella also played a role in her downfall. All of these factors ultimately led to Blanche’s tragic breakdown in the end.
The first principle character in this play is Blanche DuBois. She is a neurotic nymphomaniac that is on her way to meet her younger sister Stella in the Elysian Fields. Blanche takes two 2 streetcars, one named Desire, the other Cemeteries to get to her little sisters dwelling. Blanche, Stella and Stanley all desire something in this drama. Blanche desired a world without pain, without suffering, in order to stop the mental distress that she had already obtained. She desires a fairy tale story about a rich man coming and sweeping her off her feet and they ride away on a beautiful oceanic voyage. The most interesting part of Blanche is that through her unstable thinking she has come to believe the things she imagines. Her flashy sense of style and imagination hide the truly tragic story about her past. Blanche lost Belle Reve but, moreover, she lost the ones she loved in the battle. The horror lied not only in the many funerals but also in the silence and the constant mourning after. One cant imagine how it must feel to lose the ones they love and hold dear but to stay afterwards and mourn the loss of the many is unbearable. Blanche has had a streak of horrible luck. Her husband killing himself after she exposed her knowledge about his homosexuality, her advances on young men that led to her exile and finally her alcoholism that drew her life to pieces contemplated this sorrow that we could not help but feel for Blanche throughout the drama. Blanche’s desire to escape from this situation is fulfilled when she is taken away to the insane asylum. There she will have peace when in the real world she only faced pain.
Dissection has one essential as they give students a hand on experience. How can you get a degree to be a veterinarian if you never had a hand on experience? Contrast, you can see things you’ve been curious about. Even though they are trying to learn about animals, it’s still abusing. In an ethical eye, they can quickly absorb the looks and physical appearance of the inside of an innocent animal. On the positive side, it can be for a good cause like if animals could have cancer or they could have a deadly, unknowable, clueless, incurable disease. What if they cut that animal open and the bacteria and disease is released? Therefore, they need to pick a different strategy for dissecting animals in all vet schools.
Every year thousands of animals are euthanized due to animal testing such as cosmetic testing, medical testing, and dissection. (A Critical Look at Animal Experimentation) (Types of Animal Testing) Some of the things we use every day such as; make up, soap, furniture polish, and varieties of cleaning supplies, are tested on rabbits, guinea pigs, dogs, cats, and other animals. (Animal Testing) Cosmetic testing is used to test a product and its ingredients, medical testing finds cures for different illnesses; and dissection is used to help high school students in science classes have a better understanding of the class or students undergoing the medical field in college. (Animal Experimentation) Animal testing is not required by law; it is only used to protect companies from consumer lawsuits, provided new research for diseases, and provide a visual learning experiment for students. (A Critical Look at Animal Experimentation) It has been proven that there are more reliable and less expensive alternatives to animal testing, such as; computer models and cell and tissue tests. Animal experimentation should be eliminated because it is an inhumane method for testing purposes.
Using animals for medical experimentation, product testing, and education is a controversial subject that often leads to a large argument. While the problems can go into detail, the suffering involved in animal experimentation is painfully clear. Every year there are tens of millions of animals that die in federally and privately funded experiments. A projected 90 percent of all animals used in research are rats and mice, and many other species including guinea pigs, dogs, cats, rabbits, nonhuman primates, and farm animals are killed every year to animal testing. (UGA) The experimentation of animals and testing has not stopped because it is not the most accurate or reliable means of research, but because of the tradition, peer pressure, and large amounts of funding from those with strong invested interests into the business.

Blanche Dubois, a refined and delicate woman plagued by bad nerves, makes her first appearance in scene one of A Streetcar Named Desire by Tennessee Williams. She unexpectedly arrives in New Orleans to visit her sister Stella Kowalski who ran away after their father’s death. Upon their reunion, Blanche is sharp-tongued and quick to state her shock over the unsavory status of the apartment in comparison to the luxurious plantation where the two sisters were raised. Though dissatisfied by the living conditions, Blanche quickly explains that she had been given leave of absence from her teaching position due to bad nerves and could not stand being left alone—her excuse to invite herself to stay with Stella for an undetermined period of time. It
In Tennessee Williams play "A Streetcar Named Desire" two of the main characters Stanley and Blanche persistently oppose each other, their differences eventually spiral into Stanley's rape of Stella.
My first negative experience with animals in the lab was in a college human physiology course. We learned about the differences between the decentralized amphibian nervous system and the centralized mammalian system by sacrificing your basic frog. The procedure included decapitating the frog with a pair of scissors. No, there was no anestitia involved. The frogs went from alive to headless in one snap of the decapatron 2000. As if this were a joke, we were to demonstrate the frog's loss of equilibrium and inability to swim because...
Additionally, this earthquake occurred on a thrust fault. This fault was a subduction zone slip which occurred primarily beneath the ocean were the Pacific plate plunges underneath the North American plate. This sudden upward movement of the sea floor along the rupturing fault generated a massive tsunami. This vertical deformation

Tennessee Williams’ A Streetcar Named Desire is a play wrought with intertwining conflicts between characters. A drama written in eleven scenes, the play takes place in New Orleans over a nine-month period. The atmosphere is noisy, with pianos playing in the distance from bars in town. It is a crowded area of the city, causing close relations with neighbors, and the whole town knowing your business. Their section of the split house consists of two rooms, a bathroom, and a porch. This small house is not fit for three people. The main characters of the story are Stella and Stanley Kowalski, the home owners, Blanche DuBois, Stella’s sister, Harold Mitchell (Mitch), Stanley’s friend, and Eunice and Steve Hubbell, the couple that lives upstairs. Blanche is the protagonist in the story because all of the conflicts involve her. She struggles with Stanley’s ideals and with shielding her past.
The concurrent convective circulations in the mantle leads to some segments of the mantle moving on top of the outer core which is very hot and molten in nature. This kind of movement in different segments occurs as tectonic plates. These tectonic plates are basically seven on the earth surface as major ones, although, several small ones exist also. The plates motions are characterized by varying velocities, this variance results to sub sequential collision of two plates (leading to formation of a mountain in a convergent boundary), drift of two plates (leading to formation of rifts in a divergent boundary), or parallel movement in a transform boundary(Webcache 3).
