How To Make a Dry Ice Balloon

How To Make a Dry Ice Balloon You usually blow up balloons with air or helium, but did you know you can get a balloon to inflate itself using dry ice? Heres how you perform this simple science project: Dry Ice Balloon Materials BalloonsDry Ice PelletsFunnel (optional) Its easiest to work with a funnel because it holds the neck of the balloon open. If you are working with dry ice pellets, you may find it easier to break or crush them so you can pour them into the balloon. However, if you wear gloves, its pretty simple to do this project with just your hands and a balloon. If you have a carbon dioxide fire extinguisher, you can even make the dry ice yourself. What You Do Hold open the mouth of the balloon.Place or pour dry ice into the balloon.Tie off the balloon so that the gas wont escape.The balloon will inflate as you watch. Youll see water freeze on the outside of the balloon where the dry ice is cooling the air across the surface of the latex. How much the balloon inflates depends on how much dry ice you added. A small amount of dry ice will slightly inflate the balloon, while a large amount ultimately will make it pop. How It Works Dry ice is the solid form of carbon dioxide. At normal atmospheric pressure, dry ice sublimates from a solid directly into a gas. As the gas warms, it expands. Carbon dioxide is more dense than air, so if you drop a dry ice balloon, it will fall to the ground rather than float like a helium balloon. Dry Ice Safety Dry ice is cold enough that it can give you frostbite after a very brief exposure. Its best to wear gloves for this project and to let the balloon inflate on a countertop and not in your hand. Also, dont eat the dry ice. Keep it away from children and pets.

Inherit the Wind Essay

Inherit the Wind Essay Inherit the Wind Essay Movie Summary on the Movie Inherit the Wind Movies and films in general have been used to relay different kinds of information to different audiences in an attempt to ensure that people are able to get a certain message within which the producers and the makers of the film generally have in mind. It is a way of entertaining while at the same time, relay different kinds of information to the different people who might be in need of the same. It is not in line to indicate or assume the fact that a movie or film could be used for entertainment purposes only. The film inherit the wind was a piece of rather ingenious creation of Stanley Krame who was the overall director of the film. He sought to look into the misfortune of a science teacher (Bert Cates) who was charged and subsequently convicted of teaching the theory of evolution as according to Charles Darwin in Hillsboro located in Tennessee. This film covers more than the entertainment part of which most of the films are to cover and provides for a scenario whereby there are differences that exist whereby the freedom to inquire is generally challenged with the dogmatic thoughts which were present at that time. It goes on to accurately depict what used to happen during the early ages and time and subsequently look into the issues which dealt with the right to information and the subjects within which people were to teach and relay as information. In the film, the teacher is arrested while teaching in class and is subsequently convicted of the crime as the teaching on Darwin’s theory of evolution was not allowed. One of the major themes noticed in the plot of the movie is the right to information. There is clear depiction that the information within which people were supposed to have was limited as people were only able to have part of the information which was seen to be appropriate. The teacher was not allowed to relay this information as it was seen to be inappropriate for the audience which comprised of students in a class of history. The church, seen as the epicenter of the community was clearly unshaken when it came to the issue of which it considered the whole theory of evolution to be ungodly. The state on the other hand did not consider it to be so and thus the reason as to why there was a tussle between the two with a presidential candidate and a founder of ACLU. This therefore raises another important question which dealt with morality and the law. The church considered it to be immoral while the state was of a contrary opinion. Therefore while looking into the issue one would be forced to ask themselves whether what is morally accepted should just be the law or there should be some form of scrutiny done to establish what could amount to the law. The very nature of the fact that the church considered teaching of the theory to be immoral and did not want the children to be exposed to the same did not mean that the law necessarily advocated for the same. This was an issue which was considered to be quite weighty as different philosophers had different views on what constitutes law and whether what is generally accepted could be said to constitute law. Such were Aristotle who was a naturalist, Plato and others. The movie thus seeks to put into perspective the differing views which were present. writing company can provide you with a high-quality custom essay paper on any movie you need.

Why Vegans Dont Wear Silk

Why Vegans Dont Wear Silk Its clear to most people why vegans dont eat meat or wear fur, but why vegans dont wear silk is less obvious. Silk fabric is made from the silk that is spun by silkworms when they form the cocoons for their pupal stage, before becoming a moth. Harvesting of this silk directly harms these creatures so, because vegans do not use products that exploit animals, vegans do not use silk. Although there are multiple ways to harvest and mass-produce silkworms for their secretions, they all involve the ownership and exploitation of these small insects, oftentimes killing them in the process of harvesting their silk. Since all insects are considered sentient - or at least possessed of a nervous and therefore capable of feeling (if not experiencing) pain - vegans value their animal right to a life free of suffering. How Is Silk Made? Mass-produced silk is made from domesticated silkworms,  Bombyx mori, raised on farms. The silkworms, who are in the caterpillar stage of the silk moth, are fed mulberry leaves until they are ready to spin cocoons and enter their pupal stage. The silk is secreted as a liquid from two glands in the caterpillars head. While they are still in their pupal stage, the cocoons are placed in boiling water, which kills the silkworms and begins the process of unraveling the cocoons to produce silk thread. If allowed to develop and live, the silkworms would turn into moths and chew their way out of the cocoons to escape. The chewed silk strands would be much shorter and less valuable than the whole cocoons. Approximately 15 silkworms are killed to make a gram of silk thread, and 10,000 are killed to make a silk sari. Silk thread can also be produced by killing silkworms while they are in their caterpillar stage, just before they spin their cocoons, and extracting the two silk glands. The glands can then be stretched into silk threads known as silkworm gut, which is used mainly to make fly fishing lures. Non-Violent Production Silk can also be made without killing the caterpillars. Eri silk or peace silk is made from the cocoons of Samia ricini, a type of silkworm who spins a cocoon with a tiny opening in the end. After metamorphosizing into moths, they crawl out of the opening. This type of silk cannot be reeled in the same way that Bombyx mori silk is reeled. Instead, it is carded and spun like wool. Eri silk represents a very small portion of the silk market. Another type of silk is Ahimsa silk, which is made from the cocoons of Bombyx mori moths after the moths chew their way out of their cocoons. Because of the chewed-through strands, less of the silk is usable for textile production and Ahimsa silk costs more than conventional silk. Ahimsa is the Hindu word for non-violence. Ahimsa silk, though popular with Jains, also represents a very small portion of the silk market. Why Don't Vegans Wear Silk? Vegans try to avoid harming and exploiting animals, which means that vegans do not use animal products, including meat, dairy, eggs, fur, leather, wool or silk. Dropping silkworms into boiling water kills the worms and probably causes them to suffer - depending on whether or not they actually can experience suffering, scientifically. Even Eri silk or Ahimsa silk are problematic because they involve the domestication, breeding, and exploitation of animals. Adult Bombyx mori silkmoths cannot fly because their bodies are too big compared to their wings, and adult males cannot eat because they have underdeveloped mouthparts. Similar to cows who have been bred for maximum meat or milk production, silkworms have been bred to maximize silk production, with no regard for the well-being of the animals. To vegans, the only possible ethical way to produce silk would be to collect cocoons from wild insects after the adult insects emerge from them and dont need them any longer. Another ethical way to wear silk would be to wear only second-hand silk, freegan silk, or old pieces of clothing that were purchased before one went vegan. Are Insects Sentient? While experts disagree over how much an insect can suffer or feel pain, most at least leave the door open on the question and believe it is possible that insects feel something that we would call pain. However, an insects nervous system is different from a mammals despite also transmitting signals from stimuli that cause a response in the creature. While some conclude that insects do not feel pain, at least not in the same emotional way that humans experience pain, they still believe that all creatures are deserving of humane treatment. Even if insects do not feel pain when dropped into boiling water, a death free of pain is still a death.

Evaluate the effectiveness of the YCJA on youth crime rates and Essay

Evaluate the effectiveness of the YCJA on youth crime rates and incarceration rates - Essay Example gued that the law was effective, whereby they cited the reduced rates of youth deviancy and custody in comparison to other nations of the world (Doob & Cesaroni, 2003). Nonetheless, the country identified the importance of reviewing the law and ensuring that they implemented another law that was not divisive and controversial. In addition, the review sought to address the argument that YOA overused the country’s custodial and court systems. Moreover, the review aimed at improving efficiency in responding to minor offenders who committed serious crimes (Department of Justice Canada, 2002). Based on the foregoing, it is evident that YCJA was a compromise between politicians. Nonetheless, the act is a response to the increasingly growing number of small cases about incidents of youth offenders committing heinous crimes while also acting as a response to the growing number of cases resulting from incarceration of youths for minor offenses. Indeed, these minor offenses had resulted to a decline in the confidence that the public had on the country’s judicial system. Overall, the main objective of the legislation was to deal with crimes committed by the youth and their eventual outcome. In effect, this expose will carry out an evaluation of the role that YCJA has played on the twin aspects of youth crime rates and incarceration rates. The Canadian Coalition for the Rights of Children (CCRC) (2011) identified Canada’s youth custody rates as among the highest in the world, which is prior to the implementation and legislation of the YCJA. In effect, this implies that Canadas implementation of this law was essential in order to enable the country deal with these youthful offenders and reduce these rates. In effect, CCRC (2011) observed a 27% decline in the rate of youths charged in a court of law or recommended to facing  court charges between 2002 and 2006. It is important to point out that the Canadian legislative system made this law in 2002. In line with this,

Methods of research Assignment Example | Topics and Well Written Essays - 250 words

Methods of research - Assignment Example Answer to Question 2: The first step is to define and refine a topic. Here, the researcher starts with a clearly defined and well-focused research question and a plan. The second step is to design the search. This step involves planning the research strategy at which point the research decides on the type of literature review, its extent, and the forms of literature to include. The third step is locating the research literature. This step depends on the type of literature sought. It is usually advisable that multiple research strategies be employed in order to counteract the limitations of a single search method.
