Disposable Society Essay Example
Disposable Society Paper Disposable Society BY Arabia I quite agree with the statement we live In Disposable society. During my school years and college years, I often heard about foreign countries also I noticed that they stressed Its cleanliness. My friends and relatives told me that If we want to live In a healthy and clean environment we have to go to foreign countries such as America, London, Singapore. I always had a dream to live in theses nice countries. My dream became true now. Ten years ago, when I arrived to Chicago, I could notice cleanliness everywhere easily. That view stays in my mind ever. The park I saw with no filthy but only greenish grass. Beach has only filled with sand and water not even a single trash. The steps government followed to maintain the clean environment made me astonished. Since People spend most of their time in Park, Beach, and library. I was so surprised to see the view. I wondered, and said wow in my mind. But now everything changed! First and foremost, the city where I live at present, the view made me puzzled! Even when I go to different cities or states, the view forced me to ask think this question myself- where Is the clean environment? When e think about the matter of cleanliness, there Is no clean anywhere except everywhere trash, plastic papers, soda tins, cigarette pieces, bulk of diapers, used appliances, electronics, and furniture. Peoples action shows that they are not care about clean and healthy environment. What kind of actions led them they dont care? People are nowadays Spitting on streets, blowing their nose, throwing babys diap er, throwing chewing gum wrappers, and not being a role model for their child to maintain a clean environment.

Even though their computer might work proper but not purporting any new version of software then they are in a situation to buy new one which is compatible for their desired software. To avoid this they might buy windows operating system which Is supporting for most of the software. And about the games, once they beat one game then they are ready to buy another game. Thirdly, people are so addict of fast food, thus they use lots of using throw boxes, and dumping their garbage. Long time ago people used durable and long lasting glassware to eat their food. People like new models and fashion which lead them to buy new appliances, furniture, and new outwear. As a consequence they are throwing their used cloths this cause them to dump their garbage. Additionally, people who own the pets must keep a carry bag wherever they go with their pet, so that they can put the waste inside the bag, because the dog waste is a harmful element for people as well as animal. Some beaches and in the parks I noticed, there was a plastic carry bag to put dog waste. Finally, No one can refuse the factories are one of the factor of disposable society. For example, waste water, smoke, and air come from sugar or rubber factories. ? But handling of residues is important. Professional can establish waste water treatment method which can change contaminated water Into usable water and build under ground water tubes to prevent the contaminated water from people. So people can live disease free. Even though I see trash and not a clean environment! But people can achieve clean environment soon towards their few adjustments, by following simple steps; keeping two different trash cans for recycle and waste products, donate their used toys, furniture, appliances for recycle, have their own garden to get fresh fruits and vegetables in order to get it whenever they need it. What they expect from their society as a clean environment and not disposable society, and then they must make sure, they are in need to do the necessary steps to keep their environment as clean. Because we might come from in our family, but community consists of families, community consists of state, and so on. So we must keep in our mind and should not fail to do our obligation In order to achieve the clean environment. We have to try to change our country to make sure it is not a disposable society. We are in the time to do our action, by doing small adjustments. So that we will be relieve from living disposable society.

We are trying to find out what insulator is the best from cotton wool, bubble wrap and plastic foam Essays
We are trying to find out what insulator is the best from cotton wool, bubble wrap and plastic foam Essays We are trying to find out what insulator is the best from cotton wool, bubble wrap and plastic foam Paper We are trying to find out what insulator is the best from cotton wool, bubble wrap and plastic foam Paper Essay Topic: Sula Plan: The factor I will be changing is the type of insulator. The factor I will be recording is the temperature of the water in degrees for a total of six minutes. To record the temperature I will use a thermometer. The factors I will keep the same so it is a fair test are: Starting temperature of the boiling water Same amount / volume of water Measuring the temperature at the same interval Covering the same amount of surface area, length and width for each insulator. I intend to wrap three testubes with the chosen insulators, but leave the last one plain for control. Cotton wool Bubble wrapping Plastic foam I have also chosen to do a control experiment without insulation to see if there is a great difference in the heat loss if the container has insulation. I will then boil some water and when it is boiled I will carefully pour it into a measuring cylinder up the chosen volume (20cmà ¯Ã ¿Ã ½). I will pour it into the containers and allow it to cool to the chosen starting temperature. Once it reaches the chosen starting temperature then I will start the stop clock and record the temperature at chosen intervals. I will repeat this procedure for the next two containers. I will then repeat the whole experiment one more time to be sure that my results that I will obtain are reliable and reproducible. Equipment: I will be using the following equipment: Boiling tube Measuring cylinder Test-tube rack Thermometer Cotton wool Bubble wrap Plastic foam Sellotape Stopwatch Rubber band Prediction and hypothesis: Out of the four materials that I have been given to investigate I think that cotton wool will be the best insulator because of the heat loss. I am saying this because inside cotton wool there are many small pockets of trapped air, and air is a very good insulator in small pockets. This helps prevent convection because air is trapped into the small pockets. The next best insulator I think is the best is bubble wrap. I think that bubble wrap is the next best insulator because bubble wrap have bubbles, which is trapped of air. Therefore, conduction or radiation cannot take place. This can not take place because air is trapped into the pockets. The next insulator I think will be good is plastic foam. This is because plastic foam is made from sponge and it has many pores. Heat is prevented from being lost is that it has little holes which then can trap air. However, little conduction and radiation can still take place. I base my prediction on the following Scientific Background: All metals are good conductors and most non- metals are good insulators. The best insulators are insulators that trap air if the air cant move then it cant move then it cant transfer the heat energy by convection and a bad conductor. Things like blankets. String vests, loft insulation, polystyrene and foam are all good insulators. The more surface area there is on the boiling tube the more of the hot water will be in contact with the air and so the quicker it will cool. Insulation such as cotton wool and bubble wrap traps air that is a bad conductor this means that heat is trapped and the test tube stays hot. Conduction: Conduction is when energy is passed directly from one item to another. If you stirred a pan of soup on the stove with a metal spoon, the spoon will heat up. The heat is being conducted from the hot area of the soup to the colder area of the spoon. Metals are excellent conductors of heat energy. Other things like wood or plastics are not good conductors of heat energy. These bad conductors are called insulators. Thats why a pan is usually made of metal and the handle is made of a strong plastic. Convection: Convection is the movement of gases or liquids from a cooler spot to a warmer spot. If the soup pan above was made of glass, we could see the movement of convection currents in the pan. The warmer soup moves up from the heated area at the bottom of the pan to the top where it is cooler. The cooler soup then moves to take the warmer soups place. The movement is in a circular pattern within the pan (see picture above). Convection currents often cause wind. During the daytime, cool air from over water moves to replace the warm air over land that rises. During the nighttime, the directions changes and the water are warmer and the land is cooler. Radiation: Radiation is the final form of movement of heat energy. The suns light and heat cannot reach us by conduction or convention because space is almost completely empty. There is nothing to transfer the energy from the sun to the earth. The suns rays travel in straight lines called heat rays. When it moves like that, it is called radiation. When the sunlight hits the earth, its radiation is absorbed or reflected. Darker surfaces absorb more of the radiation and lighter surfaces reflect the radiation. So, if you wear light or white clothes outside during the summer, you would be cooler. The below diagram relates to my prediction because I am not investigating colour or day or night. I think that cotton wool would be the best insulator because cotton wool has little pockets, which can trap air into the pockets and air, wouldnt be released because air is a very good insulator. The next insulator I think is going to be the best is bubble wrap. I think this is going to be the next best because it has little bubbles, which can trap air, so no conduction radiation or convection can take place. So therefore, no air can be released. The next insulator is plastic foam. I think that this is a good insulator because it has many pores that can trap air. In addition, air is a very good insulator. Therefore, no conduction convection or radiation can take place.
