To satisfy the goals we have made in the infographic above, my group and I will perform several trial and error tests on our polymer, with each trial, we learn more, and we get closer to our perfect polymer. For our polymer to be successful, it has to have traits very similar to the ones listed above: Relatively sticky (able to stick to itself and other substances without being too messy), moldable, dry, sterile, bendable, flexible, strong, stretchy, and firm. This means, our base polymer will be gloop because the base traits of gloop are the closest to the traits we need. It is relatively sticky, dry, bendable, flexible, and sticky. And by using the formula of gloop, we can alter the traits of that polymer by changing the ingredients. This way, for minor injuries in any situation, the polymer can be used to mold fingers in a cast, patch cuts, and scratches, or protect bruises. Once we have created a polymer that matches that description, it can be used in various situations and problems. Waiting hours or even days for jammed fingers to stop hurting, having to constantly reattach bandaids, wasting material, useless trips to the hospital, and damaging the injury even more, will be nothing but a past pest as our polymer will be designed to prevent those scenarios.

About Polymers by daniel

As of 2019, polymers are seen through the eyes of common citizens as many things such as pointless slimes, wasteful plastics, and “weird science substances”. But what people don’t know is that polymers can be used to create new groundbreaking and innovative substances, whether its use is to solve daily issues or just for fun. The science and overall use of polymers create an inventive society for us to strive in.

Aside from the infinite possibilities polymers give us have, their atomic structure is just as interesting as their potential. So what is a polymer? To start out small, the big picture in the infographic above is a polymer, it may look very complex, but the actual structural pattern of a polymer is very simple. The basic physical properties for polymers can vary depending on which type it is. Some can be sticky, some can be bouncy, others can be gooey, etc; and that is the greatness of polymers, as, through science, you can create a polymer with numerous physical traits of your desire and serve meaningful purposes. But to be more specific, a polymer is a large molecule that consists of many smaller molecules called monomers, it is a very useful concept and it can be many different substances. Polymers are seen everywhere in our daily lives to the point where they are almost crucial to our daily needs. Nylon, polyethylene, and several types of plastics.

Now the next step to understanding polymers is how they are made. A monomer is a very polyfunctional molecule that is very reactive to any other molecule that is the same as itself. And as these monomers continue bonding to molecules the same as itself, it creates a very long chain of the monomer and becomes a polymer. An example of this is a substance called cornstarch in water, otherwise known as “oobleck”. Oobleck is a very interesting science phenomenon as when you add cornstarch in water, you create a substance that is neither a solid or a liquid, but a non-newtonian fluid. This meaning that the properties of the substance do not follow the laws predicted by Sir Isaac Newton. As the amount of force changes, the viscosity changes: as you apply more force to the substance, it hardens, as you apply less force to the substance, it softens. The reason that is, is because the monomers composing the oobleck behave that way when bonded with each other with water mixed in. In experiments, we used polyvinyl alcohol with borax to create slime. The PVA contained the monomers, they bonded with each other when they came in contact with each other to form long strings of that molecule. The borax influenced its physical properties and made it have slime like properties. This combination of substances creates slime. The properties of this slime can be bouncy, stretchy, non-stretchy, sticky, slippery, stringy, “rubbery”, or “liquidy” depending on the amounts of each substance you mix together.

Another branch of polymers are called synthetic polymers, these synthetic polymers are polymers that are human-made, they can be divided into 4 main categories of thermoplastics, thermosets, elastomers, and synthetic fibers. While natural polymers are usually water-based including silk and DNA, synthetic polymers are usually derived from petroleum oil and include nylon, polyethylene, polyester, Teflon, and epoxy. A great example of a synthetic polymer is polyester because it is very common in our daily life, you can find polyester in a lot of the fabrics you use and wear. Polyester was created by scientists through a reaction between acid and alcohol. Another great example of a synthetic polymer is plastic, obviously, plastic is used a lot in our daily lives to the point where in many cases, it is overused. Through a process of polymerization or polycondensation, plastics are made from natural materials such as cellulose, coal, oil, etc… Now, all synthetic materials are made from natural resources. They become synthetic material when they are chemically changed. For example, one type of process that turns natural resources into synthetic materials is called polymerization. That is when 2 resources combine or cause to combine to form a polymer. And that is when a natural resource becomes a synthetic material.

The Momentos of Memory

 

Memory, emotion, and experience are all factors in our lives that influence us to be ourselves. But what if nobody had those factors in their lives except one? In the dystopian novel, The Giver, Lois Lowry’s characterization of Jonas, shows us how he believes that a life without memory is a life without living. Jonas, the pale-eyed protagonist, is seen through the eyes of the community as an ordinary bland child given the honor of becoming the receiver; however, as Jonas experiences memories and the emotions they emit, he soon comes to disagree with the ways of the community.

To start, Jonas is unique and special in a way that separates him from everyone else. All children in Jonas’s community are genetically modified and educated to be as similar as possible, except for him, who has shown time and again how he appears to differentiate from everyone. For example, at the beginning of the story, it was unveiled that he, unlike most other citizens, has pale eyes: “…The pale eyes. Almost every citizen in the community had dark eyes. His parents did, and Lily did, and so did all of his group members and friends. But there were a few exceptions: Jonas himself, and a female Five who he had noticed had the different lighter eyes” (Lowry 20). And also Gabriel, Rosemary (The Giver’s daughter), and the Giver himself. This quantitatively proves that Jonas is special, and was not chosen to be the receiver randomly. In addition to that, the gift of pale eyes directly relates to his sudden flashes of change objects he sees from time to time: “But suddenly Jonas and noticed, following the path of the apple through the air with his eyes… the apple has changed” (Lowry 24). Just like the way the chief of the community described Jonas with the ability to see beyond.

Equally as important, Jonas is perfect for his duties as the receiver. The citizens of the community chose Jonas because he had traits that the elders did not see in anyone else. During the ceremony of the twelves, the chief elder said, “Jonas was identified as a possible Receiver many years ago. We have observed him meticulously…He has shown all of the qualities that a Receiver must have … intelligence … integrity … courage … wisdom … and the capacity to see beyond” (Lowry 62). This proves Jonas is a very special person, he has the ability, intelligence, and endurance to take in memories that come with heavy burden and pain. Nobody in the community except for Jonas and the giver has had any real memories, this indicates that they are the only two that have true emotions, individuality, unique personalities.

Furthermore, Jonas is very daring and lionhearted when it comes to the good of the community. As the story progresses with Jonas as the receiver, he obtains the full experiences of memories, the good ones, the bad ones, the emotions they emit, and the knowledge he gains from it. Despite the pain and horror from past traumas in history, he experiences feelings that have never been felt before: Happiness, joy, and love. It was that point when he saw the major flaws in his society. Everything was fake, his relationships, his family, and even his beliefs, it was life without memory. He truly believes that the life they were all living was pointless: “’Things could change, Gabe,’ Jonas went on. ‘Things could be different. I don’t know how but there must be some way for things to be different. There could be colors. And grandparents,’ he added, staring through the dimness toward the ceiling of his sleeping room. ‘And everybody would have the memories” (Lowry 128). After, he runs away with Gabe, releasing all his memories to the citizens as he searches for “elsewhere”. He sacrificed everything he had to the good of the community and with his power of memory, his last action was him emitting memories of happiness to Gabe and him as they slowly freezing in the icy tundra.

I think Jonas has a very strong connection with many other protagonists. For example, Harry Potter, he like Jonas grew up in a “normal” society in their eye, but gotten plunged into a new life. They are different from the rest as Harry has his scar and Jonas has his eyes. They excel in the true values of life and finally, their courage comes to test as they sacrifice themselves for the good of everyone else.

In the final analysis, Jonas wasn’t the ordinary obedient schoolboy everybody saw him as, but a courageous and wise hero that saved the community from the continuous void of sameness. Through memory and emotion, he created a life for everyone with memories… a life truly worth living. “The worst part of holding the memories is not the pain. It’s the loneliness of it. Memories need to be shared.”
― Lois Lowry, The Giver

春天

春天

春天是世界上的最安静和漂亮的时间,春天给所有的生命有好处。

 

安睦是小蜜蜂,他跟他的蜂巢殖民地住一起,跟他的妈妈,爸爸,兄弟姐妹,他的女王蜂,和许多其他蜜蜂一样。他们的蜂窝在一个大叔的最顶上。他们已经躲了好几个星期, 因为他们不喜欢冬天。他的刻薄的雪,他的无礼温度,和他的令人沮丧的乌云。都让我们对冬天很讨厌。

但是,一个很冷的下午,该地区的所有动物物种聚集在一起,以满足这个漫长冬季的磨难。鸟,虫子,小型啮齿动物,和很多另外的动物都来了。我们都经历了这个冬天。“我们需要蜜糖!“女王蜂说的。”我们需要蠕虫吃!“鸟们说的。”我们需要水和饭!“虫子们说的。“我们需要坚果和浆果!” 小型啮齿动物们说的。外面的大树说”我们需要太阳!“在这种情况下我们不会持续太久, 没有食物,没有营养,动物越来越弱。蜜蜂开始反抗他们的女王, 这些鸟开始突袭对方的巢穴,偷走并掠夺食物,昆虫开始变成食人族,扯下对方的头部和腹部吃,啮齿动物开始向儿童和家庭出售食物, 大树开始腐烂和堕落。

到处都是混乱。 直到有一天早上,安睦从蜂窝出来,和他没有颤抖。 陆地上有光照,地上开满鲜花,动物们四处乱窜。 冬天终于结束了! 春天来了!蜂蜜有花了,所以他们去拿蜂蜜,蠕虫出来了,所以鸟们开始吃了,河水融化,植物开始生长,所以虫子有谁和饭了,和大树有太阳喝水了,所以她们继续变得越做越大。生活是完美的,这是因为一件事!”谢谢春天!“所有的动物和树木七嘴八舌的叫。

Spring is the quietest and beautiful time in the world, and spring is good for all life.

Sam is a small bee. He lives with his hive colony, with his mother, father, brother and sister, his queen bee, and many other bees. Their cells are at the top of an uncle. They have been hiding for weeks because they don’t like winter. His mean snow, his rude temperature, and his frustrating dark clouds. Make us hate winter even more.

However, on a very cold afternoon, all the animal species in the area gathered to meet about this long winter’s suffering. Birds, bugs, small rodents, and many other animals are coming. We have all experienced this winter. “We need honey!” said the Queen Bee. “We need worms to eat!” said the birds. “We need water and rice!” said the insects. “We need nuts and berries!” said the small rodents. The big tree outside said, “We need the sun!” In this case we will not last too long, no food, no nutrition, and animals are getting weaker. The bees began to rebel against their queens. The birds began to raid each other’s lairs, stole and plundered food. The insects began to become cannibals, tearing each other’s head and abdomen to eat. Rodents began to sell food to children and families, big trees. It began to rot and fall.

There is chaos everywhere. Until one morning, Sam came out of the beehive and did not shiver. There is light on the land, the ground is full of flowers, and the animals are stalking. Winter is finally over! spring is coming! Flowers have honey, so the bees go to get the honey, the worms come out, so the birds start to eat, the river melts, the plants begin to grow, so the insects have food and water, and the big trees have the sunlight, so they continue Become bigger and bigger. Life is perfect, it is because of one thing! “Thank you for spring!” All the animals and trees are screaming.

 

Flying into Freedom


Enchanted Air: Two Cultures, Two Wings by Margarita Engle is a poetic book meant to relay the experiences of a mixed-blood Cuban American family between the 2 countries, America and Cuba, during the Cuban Revolution. The author deeply expresses how the protagonist feels about the revolution, and about the two countries. You can see her discover new things about herself and see her personality shapen into something new as she becomes more courageous and brave when she feels free. This multimedia post will explain to you the theme statement of this book.

How does low self esteem effect the decisions you make for your body?

Self-esteem is very important in every single person. It shows what we think of ourselves and how confident we are in ourselves, too much is not good for you, but too little is even worse. Having low self-esteem truly affects the way you live your life, the way you see yourself, the way you treat yourself, and the decisions that you make. A common cause of low self-esteem is someone’s body, they don’t like themselves because of the way they look and are ashamed and embarrassed by it, and go through many techniques to change their body.

The first method some people use is smoking. Many people choose to smoke because not only does it give pleasure and relief to people, it also can increase your metabolic rate. That means that over time, you will start to lose weight just by smoking. Although that sounds like an easy plan to change yourself, there are far more consequences that are likely to happen when you smoke. Smoking very heavily damages your lungs and makes you more prone to cancer and other types of diseases, as well as it is easy to get addicted to.

The second unhealthy choice is Anorexia. People use this to restrict themselves from eating, and over time, will start to lose weight. Except, that by doing this, it is very hard to see the endpoint, you will always think you are overweight no matter what, it will cause you to go on massive strict food diets. All in all, this method is just very unhealthy for you and your body and will cause muscle loss and weakness and eventually lead to disease.

Next is cosmetic surgery. People use this to improve their own appearance and make themselves more comfortable with their body image. By doing cosmetic surgery, you change a feature that you don’t like, and even though it seems like an easy way to become more attractive, doing cosmetic surgery can lead to infections and emotional danger which can damage your self-esteem even more. The best way is to avoid this is simply accept who you really are.

Weight loss surgery is another type of surgery you can have performed on you to change your body. This method is used to just cut sections of fat from you or sometimes make your stomach smaller so you physically can’t eat as much. Doing this will also lead to weight loss but it could also very easily lead to eating disorders as well as infections.

Diet pills are also a common choice to lose weight. Diet pills are consumed to make you feel full, that way you won’t get hungry and eat things. This will lead to weight loss but also very unhealthy eating routines that could cause more cons than pros.  It can increase your heart rate and like many pills have side effects and can lead to dangerous outcomes if not used properly.

Fad diets are very fast weight loss methods. Fad diets are advertised everywhere stating that they can help you lose ten pounds in just one week. Usually by very unnaturally intense workouts as well as unnatural eating routines like cabbage soup for all 3 meals of the day. Fad diets are very unreliable to use because with this going on in your daily life, it can really change things. But also because after dieting is done, it is very easy to gain all of the weight back.

Lastly, people use anabolic steroids. Anabolic steroids are synthetic, or human-made, variations of the male sex hormone testosterone. The proper term for these compounds is anabolic-androgenic steroids. “Anabolic” refers to muscle building. Some common names for anabolic steroids are Gear, Juice, Roids, and Stackers. Health care providers can prescribe steroids to treat hormonal issues, such as delayed puberty. Steroids can also treat diseases that cause muscle loss, such as cancer and AIDS. But some athletes and bodybuilders misuse these drugs in an attempt to boost performance or improve their physical appearance. People who misuse anabolic steroids usually take them orally, inject them into muscles, or apply them to the skin as a gel or cream. These doses may be 10 to 100 times higher than doses prescribed to treat medical conditions.

Misuse of anabolic steroids might lead to negative mental effects, such as:

  • paranoid (extreme, unreasonable) jealousy
  • extreme irritability and aggression (“roid rage”)
  • delusions—false beliefs or ideas
  • impaired judgment
  • mania

Anabolic steroid misuse might lead to serious, even permanent, health problems such as:

  • kidney problems or failure
  • liver damage and tumors
  • enlarged heart, high blood pressure, and changes in blood cholesterol, all of which increase the risk of stroke and heart attack, even in young people
  • increased risk of blood clots

All of these risks are not worth the chance to look bigger and tougher when it can seriously harm you to a point of death.

All in all, these methods of weight loss are not recommended to teens. Unless you have a serious condition and need any of these as treatments and medication, you should not use these. All of these methods of weight loss have very serious risks that can harm you. It is best for everybody who is trying to lose weight just by going the hard route and have healthy and regular excersize plans. This is the best way to have very good results and very low risks of danger. As well as small simple diets, the only diets that cannot harm you is the diets that prevent you from consuming the things you dont need, like sports drinks, junk food, alcholhol .Everybody should know that excersize outweighs all of the other methods as it is the most reliable and honest way to change your body to your preference. It can create more self-esteem for you and potentially change many aspects of your mental and physical life.
