How to Make Frozen Bubbles on Dry Ice

Dry ice is the solid form of carbon dioxide. You can use dry ice to freeze bubbles solid so that you can pick them up and examine them closely. You can use this project to demonstrate several scientific principles, such as density, interference, semipermeability, and diffusion. Materials Needed Bubble Solution (from the store or make your own)Dry IceGloves (for handling the dry ice)Glass Box or Cardboard Box Procedure Using gloves to protect your hands, place a chunk of dry ice in the bottom of glass bowl or cardboard box. Glass is nice because its clear.Allow about 5 minutes for carbon dioxide gas to accumulate in the container.Blow bubbles down into the container. The bubbles will fall until they reach the layer of carbon dioxide. They will hover at the interface between air and carbon dioxide. The bubbles will start to sink as the bubbles cool and the carbon dioxide replaces some of the air within them. Bubbles that come into contact with the dry ice chunk or fall into the cold layer at the bottom of the container will freeze! You can pick them up for closer examination (no gloves needed). The bubbles will thaw and eventually pop as they warm.As the bubbles age, their color bands will change and they will become more transparent. The bubble liquid is light, but it is still affected by gravity and is pulled to the bottom of a bubble. Eventually, the film at the top of a bubble becomes so thin th at it will open and the bubble will pop. Explanation Carbon dioxide (CO2) is heavier than most of the other gasses present in air (normal air is mostly nitrogen, N2, and oxygen, O2), so most of the carbon dioxide will settle to the bottom of the aquarium. Bubbles filled with air will float on top of the heavier carbon dioxide. Use a tutorial for calculating molecular mass, in case you want to prove this for yourself. Notes Adult supervision is recommended for this project. Dry ice is cold enough to give frostbite, so you need to wear protective gloves when handling it. Also, be aware that extra carbon dioxide is added to the air as dry ice vaporizes. Carbon dioxide is naturally present in air, but under some circumstances, the extra amount can present a health hazard.

Television and Media - Daytime Talk TV is Immoral Essay

Daytime Talk TV is Immoral Today’s society has become a visually based culture and, as a result, people learn and act from what they see. With the advent of television, many programs have been aired ranging from news programs to sitcoms and from game shows to talk shows, but talk shows, today, have the most effect on the public. Daily, viewers turn on their televisions and many are bombarded with images of sex, drugs, and violence on the talk shows. Unfortunately, many people are either disturbed or affected by what they see. As Vicki Abt and Leonardo Mustazza point out in their article, â€Å"Coming After Oprah: Cultural Fallout in the Age of the TV Talk Show,† â€Å"Surely long-term exposure to this genre has consequences for the†¦show more content†¦As children, they are in the stage of life when they are learning the most and absorbing everything they see, and it is natural for most of them to repeat what they see. Adolescent years are very crucial for learning how to behave and learning right from wrong, but talk shows are destroying children’s morals and their outlook on society. Therefore, there is no doubt that they are having a negative effect on our future, the children. In addition to affecting children, talk shows are affecting adults as well. Adults are observing these programs as much as children are, if not more. Our society is continually affected by what is seen, and consequently, there have even been cases of violence as a result of watching one of these talk shows. For instance, in 2000, a man by the name of Jonathan Schmitz murdered a gay man, Scott Amedure, after watching an episode of Jenny Jones in which Amedure admitted that Schmitz was his secret crush according to Ellen Willis (34). Most likely, that tragedy would not have occurred had it not been for a talk show like Jenny Jones that presents immoral topics for millions of viewers to see. This just further proves that talk shows have a negative effect on their viewers. Moreover, the viewers of the talk shows are not only affected that way, but some may also relate to the talk shows and in effect, â€Å"they believe there is a direct connection between the fictional world young people areShow MoreRelatedAn Explosion of Reality Television1968 Words   |  8 PagesIn the last decade, the explosion of Reality TV programmes has revealed the viewers preferences for realism as oppose to fiction.

To prepare graduates that conduct themselves in a professional manner by acting ethically, selfassessing, following codes of conduct and standards of practice with integrity. †¢ Review the responsibilities of the dental hygienist for reporting abuse under the Regulated Health Professions Act, as outlined in the CDHO Registrant’s Handbook and Professional Issues II (DH 202). Read the articles â€Å"Oral health professional alert: Elder abuse concern in the United States and Canada† and â€Å"Initiating discourse on recognizing and reporting child abuse†. Based on these articles, reflect on the following: Describe your responsibility and obligation when you suspect abuse in Ontario. Outline the consequences you could face if you neglected your duty. Reflect your personal opinion about this responsibility and possible consequence. Describe how you would handle a situation in the CADH clinic should you suspect abuse. Furnari, W. (2011). Oral health professional alert: Elder abuse concern in the United States and Canada. Up until 2005 Tricare had 11 regions. They merged to form the previously mentioned. Each of these regions is headed by a regional director. This person is responsible for overseeing all health care delivery activities in their specific region. Regional directors work hand in hand with military treatment facility commanders. Tricare’s most important goals are accessibility and affordability. Active duty service members, spouses and unmarried children of active duty service members and, uniformed service retirees, their spouses, and unmarried children are all eligible for Tricare. They must be enrolled in a program called DEERS (defense enrollment and eligibility reporting system) before receiving their sponsorship. Most individuals who are 65 years old and eligible for Medicare, parents’ and parents-in law of active duty service members or uniformed TRICARE Services retirees, or of deceased active duty members or retirees, and individuals who are eligible for benefits under the Civilian Health and Medical Program of the Department of Veterans Affairs are not eligible for any form of Tricare. Just like any other form of HMO, Tricare pays only their allowed services. This includes their supplies and procedures. These things are called covered charges. Covered charges include medical and psychological services and supplies that are considered appropriate care and are generally accepted by qualified professionals to be reasonable and adequate for the diagnosis and treatment of illness, injury, pregnancy, mental disorders, and well- child care. Tricare has something that is referred to as an allowable charge. It would be the equivalent to co-insurance. It is calculated by researching professional providers’ fees for similar services in the past year with certain adjustments for specific locations. Tricare has three choices available for health care. The three choices are Tricare Standard, Tricare Prime and Tricare Extra. Tricare Standard is your typically fee-for-service plan. Under this type of Tricare enrollees are allowed to choose which provider they are treated by. This is the broadest choice of providers. In many locations Tricare Standard is the only option available. Members who are eligible for Tricare Standard may also use Tricare Extra. Tricare Extra is a preferred provider option. The sponsor chooses a hospital, medical provider or any other physician that is listed in the Tricare Provider Directory. There is no annual fee for this type of Tricare. Tricare Prime is health maintenance organization type of managed care option in which MTFS are the principal source of health care. When eligible person’s sign up for this they are assigned TRICARE to a PCM (primary care manager). They must see this provider or team of providers first for all routine medical care. Tricare and CHAMPVA have many similarities. CHAMPVA is a health care benefits program for depends of veterans. Under this program the CA shares the cost of covered health care services and supplies with eligible beneficiaries. This program is managed by the VA’s Health Administration Center in Denver, Colorado. Although they both are very similar individuals who are eligible for Tricare are NOT eligible for CHAMPVA. CHAMPVA only provides benefits to eligible family members of veterans who have been declared 100% disabled due to service related injuries, survivors of veterans who died from service connected conditions, and survivors of service members who died in the line of duty who are not otherwise entitled to TRICARE benefits. Tricare is no different from any other HMO health provider. It is simply something that was established to make the individuals who serve our country have an easier time while trying to obtain certain benefits. Tricare main purpose is to improve overall access to health care beneficiaries, provide faster, more convenient access to civilian health care; create a more efficient way to receive health care; offer enhanced health care services, including preventative care; provides choices for health care and control escalating health care costs.

Rhetoric Situation in Articles

Lloyd Bitzer explores the concept of ethics. His article examines the dilemma that is associated with ethics. It is in this dilemma that the rhetorical question arises. The effect of the rhetorical question on the audience is examined. In this case, the rhetorical question is examined in the realm of art and literature.Advertising We will write a custom essay sample on Rhetoric Situation in Articles specifically for you for only $16.05 $11/page Learn More Bitzer suggests that the rhetorical question in the traditional sense is not a simple question with contradicting ideas, but a comprehensive speech. On the other hand, the concept of rhetoric is applied in narrations where a character finds gets into a situation where two contradicting actions are to be done. When a speech contains rhetoric, the weight of the rhetoric comes from the situation that the speech describes (Bitzer 1). Copyright and Fair Use The copyright and fair use article discusses the te chnicalities that exist in protecting copyrighted work. Copyright laws govern the extent to which the copyright owner can restrict the original work from being accessed. A copyright owner may give a notice to warn that his or her original work is copyrighted. Original work cannot be absolutely protected from use by a secondary party.

The professor foresaw the problem that sites such as YouTube and Napster would bring to the copyright industry. In addition, the professor depicts the copyright laws as traditional and obsolete in relation to the modern society (Lessig 3). Communication and Argument The article by Wysocki Lynch focuses on the concept of argument. An argument is a situation that arises when two or more parties hold conflicting ideas. The concept of argument is divided into two theories. In a formal argument, the parties involved in the argument hold different logical positions, while in the informal argument people have different perspectives when interpreting a certain phenomena. According to the article, people tend to ignore the opinions of those with ideas contrary to theirs. This widens the rift between the parties in the argument. This is because of lack of effective communication. The article continues to explain the steps that should be taken to enhance communication. This way, effective c ommunication reduces arguments by enabling people to understand each other (Wysocki Lynch 28) Communication and Design In this chapter of the book by Wysocki and lynch, a guide on how to develop a design plan is explained. The steps through which one would go through to develop a valid game for children are laid out. In the two chapters, design is a key factor on how communication is achieved especially in the education sector (Lynch 30). According to the book, education must have a design that students will respond to positively. Thus, communication can be improved through modification of design. Design of arguments and rhetorical situations is also explored. Importance of research is also emphasized in the book. Research begins with an idea, which is then developed into a question for which the research is done (Wysocki Lynch 63).Advertising We will write a custom essay sample on Rhetoric Situation in Articles specifically for you for only $16.05 $11/page Learn More Video Games Shape Our Culture Henry Jenkins depicts video games as the art for the digital age. Computer programs that are predictable and systematic generate video games. The widespread use of computer games by children is degrading art. Some people are against adoption of computer games as a form of art. However, the computer games are getting common in everyday life. Jenkins’s article argues that art has always been treated like the computer games. After some reluctance to accept some forms of art, the society finally accepts the arts. The article postulates that computer games are the art of the future. While on one end, the computer games are being accepted as art, on another front they are regarded as results of lack of creativity in today’s young generation. Dream Machines Will Wright pictures modern videogames as dream machines where children play games without any form of a manual. He says that the video games have substituted the real world with animated video. His article proposes that this is a new trend for human beings. We are on the course of replacing every part of our lives with electronic gadgets. The games seem contrary to this era of systematic learning. The society sees the games as a symbol of decadence. Wright then postulates that the society chooses to see the darker side of the whole affair. He supports the use of video games since they actively engage the player. He also says that the computer is used for social purposes rather that the traditional use in science. In the article, there is a prediction that games are going to be models of our own activity in the future. Works Cited Bitzer, Lloyd. Bitzer’s rhetorical situation: a heuristic endeavor..
