Investigating the Reactions between Polyvinyl Alcohol and Borax in Making a Rubber Ball Introduction Chemistry, while usually thought of as being practiced mostly in labs, actually affects everyone, everywhere. Chemistry and chemical processes are constantly occurring. We are dependent on them. The air that we breathe, the food that we eat, and thousands of other simple and confusing things depend on chemistry. In this particular case, the relationship between Polyvinyl Alcohol (PVA) and Sodium Borate (Borax) is being investigated. PVA is a water soluble synthetic polymer (Maciborski, and Salamone), while Borax is a natural mineral with many household uses. It can be used as herbicide, to bleach teeth, as a household cleaner, and a†¦show more content†¦The decision was made to manipulate the ratio of PVA to borax, as that would allow for different results. The first ratio chosen was 10:1, as it was thought to be a good starting point. However, many experiments are needed to reach a conclusion, so more ratios were tested out; the ratios 5:1, 3:1, and 2:1 were included as wel l, to get a variety of results. With all these different options, it would be possible to see which ratio was the closest and how that would impact the rest of the experiment. The Borax and PVA were poured from their respective beakers into a smaller (100mL) beaker, and then the solutions were stirred together thoroughly. This was done for all the ratios. 20 mL of PVA and 2 mL of Borax were used for the 10:1 ratio; 10mL PVA and 2mL Borax for the 5:1. 12 mL PVA and 4mL Borax for the 3:1; and 10mL PVA and 5mL Borax for the 2:1 ratio. The mixtures, after being made, were all allowed to rest in the beaker for 5 minutes. After the allotted time, the mixtures were taken out of the beakers using rubber gloves, since they are a mild skin irritant due to the fact that they contain Borax (â€Å"Material Safety Data Sheet†). They were then molded into a ball and tested for durability, shape retention, and bounce. The ones having the best of all the aforementioned qualities (5:1, 3:1, and 2:1 ratios) were then saved and put into plastic bags to be used in the succeeding

Visual Signs Of The Advertisement - 1466 Words

Living in a world that is increasing in visual signs in advertisements, it is important to note what they mean and the effect it has on us. Human beings are homo significans meaning that we are meaning-makers, one reason being that we unconsciously interpret signs by relating them to familiar structural convention. As advertisers are dependent on different conventions like fine art, photography, music, cultural codes and literary tropes, they combine signifiers and signified in order to give specific meanings to their commodities and achieve commercial value (Goldman Papson 1996) This essay will analyse the advert in semiotic terms, discussing in detail the different signifiers used for interpretations.

The Piano free essay sample

The magnetic pull of eighty-eight black and white keys on my fingers was present even before my first piano lesson. It started with my mom. She was set on her children having musical knowledge, since she never had the opportunity to take lessons when she was growing up. So, when I was 6, I started playing violin. However, I spent more time trying to plunk out the violin sheet music on the old upright piano in our living room than I did actually practicing the violin. My mom took notice, and I switched over to piano lessons. The itch in my fingers to play has only grown as I’ve grown older. I find myself seeking out a place to play whenever I have free time and wherever I am: at school, friend’s houses, and even on vacation. Sitting on the piano bench with my fingers on the keys, I am at home, even if I’m thousands of miles away from my house. We will write a custom essay sample on The Piano or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The moment I sit down at a piano, I unconsciously let out a huge breath, like I’ve been holding it in since the last time I played. A wave of serenity washes over me as I twiddle my hands for a second, deciding where on the keys to start. As my fingertips meet the cool, smooth ivories, my worries vanish. All the cares of the day fade away with the first note; any problem can be resolved by resolving a chord. The world fades to the black and white of the keys in front of me. Playing piano is therapeutic for me because I can take a break from the stress of reality and express my feelings through the music I play. Suddenly, emotions that, in my head, are swirling and confusing can be released through my fingers into musical patterns. I can spend hours at a piano without realizing the passing of time. Lost in music has always been my favorite place to be, and the piano is my favorite place to get lost. There have been several low points in my life where I’ve wanted nothing more than to get lost. During those moments, the piano was a constant source of consolation and comfort. Music has been there for me at times when no one else has. To be able to spread that support and inspiration to others through my own playing is one of the reasons I love to play so much. Piano is an incredibly expressive instrument. It is easy to connect to others while playing, whether it’s through a dramatic, complicated piece that touches on people’s heartstrings or the simple chords of Top 40 tune that get everyone singing and dancing along. Yes, I get lost in the music, and love to encourage others to do the same. But being at the piano is a powerful place for me to be because more often than not, I have found myself there. Playing piano has allowed me to discover and shape bits of myself that otherwise would’ve gone unnoticed. It gave me a channel for my emotions and a pathway to expressing my individuality. Meticulous practice has reaped for me the rewards of a solid work ethic, patience, and other disciplines. When writing my own music, my creativity and imagination can run free. Playing piano gives me a voice that can stand out in a crowd, and I am confident in that voice. These qualities I have learned and developed have followed me into areas of my life outside of music, allowing me to face day-to-day life with more certainty in myself and my abilities. Sitting on a piano bench with my fingers on the keys is the happiest and most familiar place for me to be because it is the easiest place for me to be myse lf.

Religion at Work

Religion is a fundamental set of beliefs and practices that are generally agreed upon by a number of persons or sects. In the Civil Rights Act of 1964 legislation, Religion include all aspects of religious observance and practice, as well as belief; unless an employer demonstrates that he/she is unable to reasonably accommodate an employee’s or prospective employee’s religious observance or practice without undue hardship on the conduct of the employer’s business (FindUSLaw, 2008).Advertising We will write a custom essay sample on Religion at Work specifically for you for only $16.05 $11/page Learn More The meaning of reasonable accommodation is determined by the human resources. On the other hand, undue hardship may differ from employer to employer. However, religious accommodation may be granted if it does not in any way infringe on the rights of the other workers. Certain practices are easily accommodated while others cannot be ac commodated in the workplace. This paper covers the religious practices of the orthodox Jewish, the Hindu and the Church of Jesus Christ of Latter-day Saints’ practices, and whether these practices can be accommodated in the workplace, or not. One of the main practices of the three aforementioned religions is the observance of holy days during which some of their religious faithful are not allowed to work. The Orthodox Jewish day of rest (Sabbath) is Saturday. On this day, the use of all electrical appliances is highly prohibited. This includes driving, turning on lights, or even cooking. The Mormon holy day is Sunday and on this day, Mormons are advised to rest and worship. Mormons celebrate two religious festivals namely, Easter and Christmas. In the other hand, Hindus have many festivals whose dates change from year to year. During these festivals, they worship, fast, feast, and perform other rituals. Some of these practices can be accommodated in the workplace. Those emplo yers who require their employees to work on Saturdays can make an exception. Some practices that may not be accommodated include fasting if the employees were too weak to work. Orthodox fast days are spread throughout the year. During this time, no food or water is consumed for 25 hours (Rabin, 2011). This could be considered as undue hardships. Certain religious practices require a certain dress style. Orthodox Jewish women wear head coverings and are not allowed to wear pants while Jewish men grow sideburns and wear hats. Hindu women wear a special dress known as a mangalsutra while orthodox Hindu men grow a small pony tail on the back of their heads. Mormons are required to wear modest clothing that is not clingy. If a dress style poses a security risk, it cannot be accommodated.Advertising Looking for essay on religion theology? Let's see if we can help you! Get your first paper with 15% OFF Learn More There are clothes that may be inappropriate for certain jobs e specially those that are likely to get tangled up in machinery. If a dress code is not in line with the organizations’ public image or if it does not promote a productive work environment, the employer has a right not to accommodate it. If a dress code is based on business needs and applied uniformly, it generally will not violate employee civil rights (Thomas, 2007). The three religions have strict guidelines on what food should be consumed. The Mormons do not drink caffeine or tea or any beverage that may be addictive. They are also encouraged to consume grains, herbs and fruits and to eat meat sparingly. Some Hindus do not eat meat, fish or eggs and the orthodox Jewish do not eat foods that are not kosher. This is a practice that can be accommodated by an employer by providing a wider variety of foods on their menu and ensuring that Hindu foods are cooked and heated in different containers from the ones used for cooking meat. The Hindu paradigm of Dharma-of doing oneâ€⠄¢s duty is a powerful force in the workplace. Dharma is not enough because Hindus have been castigated for being clannish and unwilling to mix with others (Srinivasan, 2007, p. 1). This has been attributed to the caste system. If the job they are doing involves networking or working in teams, this behavior cannot be accommodated. This decision is also strengthened by the fact that the caste system is illegal in India where the Hindu community originated from. It’s not unlawful for an employer to take action against an employee in a foreign country if compliance with the employee’s demand would cause the employer to violate the law of the foreign country (FindUSLaw, 2008). The prayer requirements of the three religions vary. Many Hindus are required to pray three times a day. During this time, they bring a plate, a cup of water and a spoon. Accommodations can easily by providing space where they can pray and store their prayer items. The orthodox Jewish and Mormon dail y prayer practices do not require special considerations. There are instances where the employer is allowed by law to hire employees based on their religion. If religion is a bonafide occupational qualification reasonably necessary to the normal operation of that particular business or if the employer is an education institution owned, supported or controlled by a particular religion (FindUSLaw, 2008).Advertising We will write a custom essay sample on Religion at Work specifically for you for only $16.05 $11/page Learn More Reference List FindUSLaw.
