Air Pollution Essay - 1322 Words

All living things use air and it must be clean to maintain life on earth. When air pollution becomes the subject, what do you think about? Smog, acid rain, and other forms of outdoor pollution are the common things people think about. Air pollution can also exist indoors as in closed ventilated areas that we surround. This makes the air that we breathe indoors inescapable and the pollution exist both indoor and outdoor. For example, hair spray usage indoor is polluting the air inside because of the emissions of toxic chemicals used to create the product are present within a spray of it. On a typical outdoor summer day in Fresno, the smog from vehicles exposed into the air which makes the air brown and can be seen miles away from highways.†¦show more content†¦The sources used which gives off gases or particles are cooking oils, hair sprays, aerosols, household cleaning products such as bleach and Pinesol have the greater effect or even insecticide sources that kills rats, ro aches, spiders and ants. According to World Health Organizations, â€Å"Cooking and heating with solid fuels on open fires or traditional stoves results in high levels of indoor air pollution. Indoor smoke contains a range of health-damaging pollutants, such as small particles and carbon monoxide.† The inadequate ventilation from using these products can increase the indoor air without outdoor air to dilute the emissions. The relative importance of a source used depends on how much emissions gives out on an object and evaporates in the air surrounding the user. Another factor from using building materials can give off high pollutant in some cases an improperly adjusted gas stove can emit high amounts of carbon dioxide than the properly adjusted one. Air pollution happens when sources are emitted into the air and it is caused by human activities from operating that source. Creating the pollution indoors is more harmful because it affects the air quality inside and it stay indo ors if not ventilated properly. The activities from using the sources are causing these pollutions and we do not know that we are causing these pollutions to occur indoor.

What Is a Controlled Experiment

A controlled experiment is one in which everything is held constant except for one variable. Usually, a set of data is taken to be a control group, which is commonly the normal or usual state, and one or more other groups are examined where all conditions are identical to the control group and to each other except for one variable. Sometimes its necessary to change more than one variable, but all of the other experimental conditions will be controlled so that only the variables being examined change. And what is measured is the variables amount or the way in which they change. Controlled Experiment A controlled experiment is simply an experiment in which all factors are held constant except for one: the independent variable.A common type of controlled experiment compares a control group against an experimental group. All variables are identical between the two groups except for the factor being tested.The advantage of a controlled experiment is that it is easier to eliminate uncertainty about the significance of the results. Example of a Controlled Experiment Lets say you want to know if the type of soil affects how long it takes a seed to germinate, and you decide to set up a controlled experiment to answer the question. You might take five identical pots, fill each with a different type of soil, plant identical bean seeds in each pot, place the pots in a sunny window, water them equally, and measure how long it takes for the seeds in each pot to sprout. This is a controlled experiment because your goal is to keep every variable constant except the type of soil you use. You control these features. Why Controlled Experiments Are Important The big advantage of a controlled experiment is that you can eliminate much of the uncertainty about your results. If you couldnt control each variable, you might end up with a confusing outcome. For example, if you planted different types of seeds in each of the pots, trying to determine if soil type affected germination, you might find some types of seeds germinate faster than others. You wouldnt be able to say, with any degree of certainty, that the rate of germination was due to the type of soil. It might as well have been due to the type of seeds. Or, if you had placed some pots in a sunny window and some in the shade or watered some pots more than others, you could get mixed results. The value of a controlled experiment is that it yields a high degree of confidence in the outcome. You know which variable caused or did not cause a change. Are All Experiments Controlled? No, they are not. Its still possible to obtain useful data from uncontrolled experiments, but its harder to draw conclusions based on the data. An example of an area where controlled experiments are difficult is human testing. Say you want to know if a new diet pill helps with weight loss. You can collect a sample of people, give each of them the pill, and measure their weight. You can try to control as many variables as possible, such as how much exercise they get or how many calories they eat. However, you will have several uncontrolled variables, which may include age, gender, genetic predisposition toward a high or low metabolism, how overweight they were before starting the test, whether they inadvertently eat something that interacts with the drug, etc. Scientists try to record as much data as possible when conducting uncontrolled experiments, so they can see additional factors that may be affecting their results. Although it is harder to draw conclusions from uncontrolled experiments, new patterns often emerge that would not have been observable in a controlled experiment. For example, you may notice the diet drug seems to work for female subjects, but not for male subjects, and this may lead to further experimentation and a possible breakthrough. If you had only been able to perform a controlled experiment, perhaps on male clones alone, you would have missed this connection. Sources Box, George E.

Friendships Should Not Be Based On Social Media - 1253 Words

Friendships in the 21st century do not have the same importance and worth as they used to. Friendships now are seen as being friends on social media but never speaking a word to each other in real life. Saying hi s and hellos in the hallways , but not a word more. Friends should be a tight knit community where one can relax in an environment of love, affection and safeness. Where they can be vulnerable and comfortable enough to share their fears and their secrets. Friends know us better than we know ourselves, they have been with us from the beginning . The eye contacts that are made when someone s talking has gotten too much, the inside jokes that only you guys know. Friendships should not be based on social media nor how popular a person is. They should be based on a persons personality their character. For viewers in 2015, Friends disrupts the current value placed on friendship. From our first cry to final breath, we have developed friendships throughout our lives. There are countless articles that argue whether or not people who have had stable friendships at a young age affect their personalities and characteristics as they age. In Thomas Berndt’s â€Å"Friendship Quality and Social Development, the paper argues that those who have stable relationships as a child and continue as they grow up show signs of social stability, intimacy, and low levels of conflicts and rivalries, but those who do not are more shy and withdrawn (1).
