Cell Phones in Schools Essay Example for Free

Cell Phones in Schools Essay Who can work while listening to the incessant ringing of a cell phone? This does not creat an inviting classroom environment for students. Although cell phones would be useful in the event of an emergency, they should not be allowed in schools because of the increased amount of disruptive and social problems. Despite the interruptions, cell phones do provide on advantage. They allow quick communications during times of an emergency; they also enable students to contact their parents at any time for any reason. One example might be: if a student forgot that they have an after school affair to attend for that day, such as a sports practice or tutoring, they could easily notify their parents of the newly needed pick-up time. However, this convenience does not outwiegh the problems cell phones can cause. Disturbances during the school daycan cause students a great distraction. They could ring during class, and students attention would divert from the lesson to the phone. Students could want to chat in between classes, causing many tardies. They would also cause a riot if lost or stolen. Besides these factors, allowing cell phones in school could cause an influx of social problems. Kids are already picked on over a number of issues, such as appearances, financial status, etc. If a student is not fortunate enough to afford a cell phone, this would give cause for the other students to tease them. Overall, cell phone use in school might be slightly advantageous in an emergency sitituation, but they should not be allowed because the problems outweigh the benefits by far.

 The Civil War lasted for four years, three weeks, and six days. The Civil War caused a numerous amount of good and bad things. Along with the union coming out victorious, slavery was abolished, territorial integrity was gained, the reconstruction era began, and Abraham Lincoln was assassinated. Although, many people were involved in the process leading up to the civil war. Abolitionists played a huge role in the progression in civil rights. They fought for the freedom of slaves and the ceasing of slave trade from Africa. There were many activists involved in this movement, including Harriet Tubman and Sojourner Truth. These two women abolitionists are two of the most dynamic woman and well known abolitionists. Although Harriet Tubman and Sojourner Truth have many similarities, they have certain aspects that allow them to differ from each other. Despite their slight differences, Tubman and Truth were seemingly the most efficient and effective in their duties as abolitionists. Consequently, Harriet Tubman was born a slave into a slave family. As a slave, at five years old, Tubman was "rented" to families where she was put to work winding yarn, checking animal traps, cleaning the houses and nursing children among many more laborious tasks. When she was older, she decided she prefered to work outside of the house as opposed to laboring inside the house with domestic chores. As a teenager, she would upset her owners and often was reprimanded and sent home because of her rebellious attitude. Later on in Tubman’s life, she married a free man and also found out that her mother was freed by her owner, but her mother was never informed of her freedom. This directly affected Tubman because her mother’s freedom also meant that Tubman was b... ...ght her battles and was often victorious. According to Sandra Johnson, in her article Truth and Tubman: Women who fought against slavery, in the Austin Weekly News, 2005, Tubman did not feel Lincoln was working hard enough to free slaves, yet when Truth met with Lincoln she praised him for his efforts. One more difference between the two women is that Tubman worked to free slaves, but Truth fought for women’s rights in addition to ending slavery. In summation, Tubman and Truth were exceptionally brave women who fought for ideals in which they strongly believed. While Tubman’s courage was founded in a rebellious nature, Truth’s courage was based in her faith in a Higher Power. Both women, despite their differences in opposing their foes, have rightfully earned their positions as heroines in American history with their efficient and effective duties as abolitionists.

Answer the following questions in the space provided. Remember to use complete sentences to demonstrate comprehension and understanding. Based on the labs you completed, answer the following questions: 1. Which solute(s) were able to diffuse into the right beaker from the left beaker? Which did not? Answer: The solute(s) that were able to diffuse Na+/Cl- , Urea, Glucose. The solute that didn’t was Albumin. 2. Explain the relationship between the rate of diffusion and the size of the solute.What do you think changes in temperature such as cold/hot would have on the diffusion rate? Answer: The rate of diffusion of molecules depends on how soluble they are. The rate of diffusion depends on the size of the molecule in general, small molecules would pass through a membrane faster than larger molecules. As temperatures increase, molecular movement increases. As the movement increases, so will the diffusion rate as the molecules spread faster and faster.The opposite would be true of colder temperatures. 3. Considering the osmosis lab, explain the relationship between fluid volume and osmotic pressure. Answer: Osmotic pressure is the measure of the tendency for osmotic flow to occur. Osmotic flow is from a solvent to a solution. This is the amount of pressure that needs to be applied from the outside to prevent osmosis. Fluid volume might be connected to osmotic pressure as the amount of pressure required to contain a specific volume of fluid in a container.Both pressures are external. 4. Describe a situation that demonstrates diffusion and a situation that demonstrates osmosis occurring either in the human body or in the environment. Answer: Diffusion is molecules moving from an area of high concentration to an area of low concentration. For example, ammonia molecules have a powerful odor. When a stopper is removed from a beaker containing ammonia, the molecules move from the area of high concentration diffusing themselves throughout the air.This true as the od or becomes noticeable even in far reaches of the room where it was released. Osmosis occurs when molecules on one side of a semi-permeable membrane cross through the membrane. If the two solutions are of different concentrations, but the molecules of one are smaller and can diffuse the membrane, then we have osmosis or molecules moving from an area of higher concentration to an area of lower concentration. A common example is the absorption of water by the roots of a plant from the soil. 5.After reviewing the four tissue types in the Histology Atlas, choose the tissue type you think is most important in the human body and explain your reasoning. Answer: There isn’t such thing as most important tissue. The reason we have different tissues is that we cannot exist without any of them. If I had to choose one it would be Epithelial Tissue because covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialized to form the covering or lining of all internal and external body surfaces.

When I was about five or six years old, the adults around me noticed that I did not write normally. I failed to differentiate between lowercase â€Å"b’s† and â€Å"d’s.† I wrote interchangeably from left to right and from right to left. My handwriting was close to illegible. When I was twenty-five, I was nominated for an Emmy in comedy writing because I do not write normally. Now, as a teacher, I recognize how flexible, how particular, my teachers were in their teaching—in what they assessed, and when they intervened or corrected me. I had teachers who were able, empowered, inclined and, ultimately, trusted to consider what my particular strengths and weaknesses meant in the context of me; what not writing normally meant in the context of how I talked about dinosaurs, made up stories about blocks, and told jokes. There is a privilege in that kind of education, in being specifically considered, not just with expertise, but also with genuine interest. It was a privilege to have never felt lacking because I needed something different. I have spent most of my teaching career at ELLIS Preparatory Academy, a small high school in the South Bronx. Our school is part of the Internationals Network for Public Schools.
