Exploding Balloons Science Project

Exploding Balloons Science Project Im sure you are well aware you can fill a balloon with a flammable gas, ignite it and cause it to explode. How about something a little less dangerous? Heres a quick and easy project you can try that allows you to produce a fireball, without a whole lot of risk to yourself, others or property. Heres what you do: Exploding Balloon Materials You will need small balloons and one or more of the following powders: CornstarchNon-dairy creamerPowdered sugarPowdered milkLycopodium powder There are other powders that will work, but these are non-toxic and not ordinarily flammable. Make Exploding Balloons Add about a teaspoon of any of these powders to your balloon. If you have a small funnel, that will greatly simplify things. Otherwise, crease a sheet of paper and use it to deliver the powder into the balloon.Blow up the balloon and tie it off. You can do this the old-fashioned way or you can use compressed air. If you are a daredevil you can use oxygen or hydrogen, but that defeats the purpose of my nice safe project.Place the balloon some distance away from you and use a lighter or candle on a meter stick to pop it and ignite the powder.

Biography of Tiberius, 1st Century Roman Emperor

Biography of Tiberius, 1st Century Roman Emperor The Roman emperor Tiberius (November 16, 42 BCE–March 16, 37 CE) was a very capable military leader and a sensible civic leader who tried to restrain Romes out-of-control budget. But he was also dour and unpopular. He is known primarily for his trial for treason, sexual perversion, and eventually shirking his responsibility by going into seclusion. Fast Facts: Tiberius Known For: Roman Emperor in the first century CEBorn: November 16, 42 BCE on the Palatine Hill, RomeParents: Tiberius Claudius Nero (85–33 BC) and Livia DrusillaDied: March 16, 37 CE in RomeEducation: Studied with Theodous of Gadara and Nestor the AcademicSpouse(s): Vipsania Agrippina (m. 19 BCE), Livia Julia the Elder, (m. 11 BCE)Children: Drusus Julius Caesar (with Vipsania), Julia, Ti Gemellus, Germanicus (all with Julia) Early Life Tiberius was born on November 16, 42 BCE on the Palatine Hill or at Fundi; he was the son of the Roman quaestor Tiberius Claudius Nero (85–33 BC) and  his wife Livia Drusilla. In 38 BCE, Livia was forced to divorce Tiberius Nero to become the wife of the first Roman emperor Augustus. Tiberius Nero died when Tiberius was 9 years old. Tiberius studied rhetoric with Theodorus of Gadara, with Nestor the Academic and perhaps with Athaneaus the Peripatetic. He became fluent in Greek and meticulous in Latin. In his early civic career, Tiberius defended and prosecuted at court and before the Senate. His successes at court included the securing of a charge of high treason against Fannius Caepio and Varro Murena. He reorganized the grain supply and investigated irregularities in slave barracks where free people were detained improperly and where draft dodgers pretended to be slaves. Tiberius political career soared: he became quaestor, praetor, and consul at a young age, and  received the power of a tribune for five years. Marriage and Family In 19 BCE, he married Vipsania Agrippina, the daughter of the renowned general Marcus Vipsanius Agrippa (Agrippa); and they had a son, Drusus Julius Caesar. In 11 BCE, Augustus forced Tiberius to divorce Vipsania and marry his daughter Livia Julia the Elder, who was also the widow of Agrippa. Julia had three children with Tiberius: Julia, Ti Gemellus, and Germanicus. Early Military Accomplishments Tiberiuss first military campaign was against the Cantabrians. He then went to Armenia where he restored Tigranes to the throne. He collected missing Roman standards from the Parthian court. Tiberius was sent to govern the long-haired Gauls and fought in the Alps, Pannonia, and Germany. He subjugated various Germanic peoples and took 40,000 of them  as prisoners. He then settled them in homes in Gaul. Tiberius received an ovation and a triumph in 9 and 7 BCE. In 6 BCE, he was ready to accept command of the eastern Roman forces, but instead, at what would seem to be a height of power, he abruptly retired to the island of Rhodes. Julia and Exile By 6 BCE, Tiberius marriage to Julia had gone sour: by all accounts, he regretted leaving Vipsania. When he retired from public life, Julia was banished by her father for her immoral behavior. His stay on Rhodes lasted at least eight years, between 6 BCE and 2 CE, during which time he wore a Greek cloak and slippers, spoke Greek to the townspeople, and attended philosophical lectures. Tiberius tried earlier to return to Rome when his tribunician power ended, but his petition was denied: thenceforth he was referred to as The Exile. After Lucius Caesar died in 2 CE, Tiberius mother Livia arranged for his recall, but to do that, Tiberius had to renounce all political aspirations. However, in 4 CE after all other likely successors had died, Augustus adopted his step-son Tiberius, who in turn had to adopt his nephew Germanicus. For this, Tiberius received tribunician power and a share of Augustuss power and then came home to Rome. Later Military Accomplishments and Ascension to Emperor Tiberius was given tribunician power for three years, during which time his responsibilities would be to pacify Germany and suppress the Illyrian revolt. The German pacification ended in disaster in the Battle of the Teutoburg Forest (9 CE), when an alliance of Germanic tribes destroyed three Roman legions and their auxiliaries, led by Publius Quinctilius Varus. Tiberius did achieve complete submission of the Illyrians, for which he was voted a triumph. He postponed the triumph celebration out of deference to Varus disaster in Germany: but after two years more in Germany, he settled things and put on a triumphal banquet with 1,000 tables. With the sale of his spoils, he restored the temples of Concord and Castor and Pollux. As a result, in 12 CE, the consuls awarded Tiberius joint control of the provinces (co-princeps) with Augustus. When Augustus died, Tiberius, as tribune, convened the Senate where a freedman read Augustus will naming Tiberius as successor. Tiberius called on the praetorians to provide him a bodyguard  but didnt take the title of emperor immediately nor even his inherited title of Augustus. Tiberius as Emperor At first, Tiberius despised sycophants, intervened in matters of state to check abuses and excesses, abolished Egyptian and Jewish cults in Rome, and banished astrologers. He consolidated the Praetorians for efficiency, crushed city riots, and abolished the right of sanctuary. However, his reign turned sour when informers accused Roman men and women of many, even silly crimes that led to capital punishment and confiscation of their estates. In 26 CE, Tiberius exiled himself to Capri, leaving the empire in control of his Socius Laborum (partner of my labors), Lucius Aelius Sejanus. In Capri, Tiberius stopped fulfilling his civic obligations  but instead engaged in licentious acts. Most notorious is his training of little boys to act as nipping minnows or tiddlers, to chase him when he went swimming in the imperial pool, nibbling between his legs. Tiberius mean and vengeful streak caught his erstwhile confidant, Sejanus, accused of conspiracy against the emperor. Sejanus was executed for treason in 31 CE. Until Sejanus was destroyed, people had blamed him for the excesses of the emperor, but with his death, the blame rested solely on Tiberius. The empire continued to run on without the direct input of the emperor, who remained in Capri. During Tiberius exile in Capri, Gaius (Caligula) came to live with Tiberius, who was his adopted grandfather. Tiberius included Caligula as joint heir in his will. The other heir was Tiberius brother Drusus child, still a teenager. Death Tiberius died on March 16, 37 CE, at age 77. He had ruled for nearly 23 years. According to Tacitus, when it looked as though Tiberius would die naturally, Caligula tried to take sole control of the empire. Tiberius, however, recovered. At the request of Caligula, the head of the Praetorian Guard, Macro, stepped in and had the old emperor smothered. Caligula was named emperor. Sources Balmaceda, Catalina.

Who influence me - Essay Example It was after several months of training that she went to India and took her initial vows as a nun. Teresa taught at St Mary’s high school in Calcutta from 1931 to 1948. During her stay at the convent, Teresa saw how the poor suffered. This resulted to her being granted permission to go and work amongst the poorest of the poor in the slums of Calcutta. Depending on divine providence, Teresa started an open school at the slums of Calcutta. Fortunately, she was joined by many volunteers and financial aid also increased. As a result, Teresa was able to expand on her line of work (Nobelprice 1979 par 2). Teresa started her own order in October 7, 1990 after getting permission from the Holy See. She named it "The Missionaries of Charity". The task of the Missionaries of Charity was to take care of the less fortunate that had no one to take care of. The Missionaries Charity became an international religious family under Pope Paul IV. Currently the order has active and contemplative branches comprising of sisters and brothers in many countries. Between 1963 and 1984, several branches were established; Contemplative branch of the Sisters and the Active branch of the Brothers was founded in 1963, the Contemplative branch of the Brothers was added in 1979 and the Priest branch was established in 1984. The Missionaries Charity has over the years spread all over the world including the former Soviet Union and some Eastern European countries. They take care of the less fortunate people in continents like Asia, Africa and Latin America. They also assist people affected by catastrophes like, famine, floods and epidemics. The Missionaries Charity society has home all over the world where they take care of, AID’S victims, homeless, alcoholics and even shut-ins. On March 29, 1969, Co-workers aided and assisted the Missionaries Charity to become an official international

Discuss the benefits , limitations and methodology of population Essay - 1

Discuss the benefits , limitations and methodology of population screening for breast cancer - Essay Example The subject of whether breast cancer screening is more harmful than helpful has fuelled controversy and debate from various quotas for almost, as long as, the technology to do it has been in existence. The dominant question is often; whether the benefits of the procedure outweigh the perceived negative effects that may result from the process. These harms include over diagnosis, where women are treated for cancer while it might not have been clinically manifested in their lifetimes; conversely, several benefits have been attributed to the screening prominently among them, prevention of death. The rationale used to justify screening is usually because it has been successful in detecting breast cancer in the screened population, especially in view of the increased rates of cancer in the last few years. Experts on the subject project that because of the mass tests, the risk will go down and the cancer rates eventually reduced due to early detection and that should be the confirmation of the importance of screening (Cancer Research UK, 2012). The primary focus of this paper will be an examination of the process and principles of screening for breast cancer in populations through histopathology, and then discuss the benefits and harms that are likely to result. Professionals in the health community share the belief that early cancer diagnosis translates into a better chance for mitigation, nonetheless, not everyone who has signs of cancer will benefit from the diagnosis since the cancer my regress without treatment. Thus, to ensure the potential benefits outweigh the harm, there must exist sufficient evidence from randomized tests or trials to indicate that a specific population will benefit from cancer screening, therefore certain principles must be followed before public screening is allowed. There must be significant burden of the disease in the

Impressionism in Writing and Art Essay -- Exploratory Essays Research

Impressionism in Writing and Art Realizing that their art would be overshadowed at major art exhibitions such as the Salon in Paris, a group of artists created their own exhibition. Following the painters’ first show in 1874, critics picked up on the title of one of Claude Monet's paintings, Impression, Sunrise 1872. Between 1874 and 1886 this group, dubbed â€Å"impressionists†, put on eight shows in all. Edgar Degas, Camille Pissarro, and Claude Monet were three of the more well know artists of the movement (http://www.bbc.co.uk/arts/ impressionism/intro1.shtml). Although not necessarily a cohesive group, impressionist paintings all contained certain characteristics. The artists used very informal techniques while capturing the light and true color of their subjects. Their paintings have a very realistic feel when looked at from a far, however when viewed close up one can clearly see the short, blotchy strokes used by the artist. The paintings of Impressionists were immediate sensations which often captured the artists’ interpretation of everyday life. Diego Martelli remarked that impressionist painters do not â€Å"fabricate their theories first and then adapt the paintings to them, but on the contrary†¦the pictures were born of the unconscious visual phenomenon of men of art (Martelli 2)† Around the same time period a group of writers also demonstrated impressionistic ideals in their writings. As is the case with impressionist painters, writers of the impressionist movement are also difficult to classify. Critics have argued that Joseph Conrad, James Joyce, Stephen Crane and others could all be considered to have impressionistic ideas in their writings.

Global Warming: Causes and Effects Essay

This is a situation where there is a pronounced relative increase in the average temperature on the surface of the earth alongside with the core ocean body temperature. The occurrence was noted about the middle of 20th century with grave progression of economic and geographical impacts on the universe. Introduction Intergovernmental Panel on Climate Change, IPCC, projects that the global warming will continue to increase at such an unprecedented rate with unabated majority due to human causes. There is already rising level of sea water, the glacial withdrawal, and arctic spatial reduction. The altered pattern of agricultural practice is one of the implicated consequences of human acts. Ranges of direct effect cut across weather active events, health implications, disruptions of primary or secondary concession of the ecosystem, and finally, the economic disaster. Concerned bodies all over the world are seriously moving towards reversing the human derived natural disaster characterized of the effects of global warming. With increase in industrialization and world development and latent effect deposited by already released causative gases, global warming is envisaged to be further aggravated with an average temperature change from 1. 10C of the mid-20th century to 6. 40C towards the middle of 21st century. The Causes of Global Warming Minimum of thirty scientific researchers in academic fields through the submissions of IPCC endorsed the following as direct and indirect causes of green house effect. A larger percentage is caused by atmospheric presence of greenhouse gases like carbon IV oxide, water vapor retention in the atmosphere, methane and ozone layer depletion. These gases are collectively called – â€Å"anthropogenic gases†. Other industrial releases are oxides of nitrogen, sulphur floride compounds, hydrofluorocarbons, per fluorocarbons, and chlorine containing fluorocarbons. Unregulated open ground burning of fossil fuels for industrial use and others results in exhaust of large amount of carbon IV oxide into the atmosphere. Crude petroleum refining, natural gas crystallization, coal burning, and products from Cement Company are implicated. In pre-developmental era, occurrence of global warming is traced to natural sources which include the release of solar emissions following natural disasters; volcanic eruptions, earth quaking, magma accumulation et cetera (Hegerl, 2007) The Effects of Global Warming The gaseous accumulation of greenhouse gases above the earth surface causes retention of reflecting sun rays from the ground. Sun rays contain component that produce heating effect (ultraviolet rays), hence basal temperature will rise from 3-50C about century to come. This is fatal to life. The temperature rise causes latent heat expansion of the ocean leading to increase in normal volume by about 20 meters. It can lead to change in weather seasonal pattern with predominance of drought, low rainfall, leading to famine and low industrial energy input and output. Also, there would be increased spread of epidemic plagues and other communicable diseases in an unprecedented manner. There is death of aquatic life leading to water pollution, spread of water-borne diseases, and malnutrition. There would be economic regression with insurance industries at larger risk because the resulting natural disasters present insurers with evident claim for rebuilding. Continent like Africa stands the greatest economic risk because about 70% of the population relies on Farming. Carbon dioxide and other gaseous retention are toxic to plant. Other economic implication entails increase in transportation maintenance, massive migration from glacial shift, flooding which disturb normal economic of some developing countries that base at the sea bank. Outline and Draft The Cause and Effect of Global Warming 1. Definition of Global Warming: i. Increase in average basal land and sea’s temperature 2. Introduction i. IPCC projects worsen situation with aggravation if anthropogenic course is not reversed with 1. 10C to 6. 40C temp. rise towards the mid-21st century. ii. Global warming exist prior to developmental era, during developmental and at development age in connection with interwoven reasons. Developed countries stand the greatest risk of exposure to causative gases. 3. The Causes of Global Warming i. â€Å"Anthrogenic gases† such as oxides of nitrogen, sulphur floride compounds, hydrofluorocarbons, per fluorocarbons, and carbon IV oxide ii. Poor control of energy generation from natural resources: natural gas, coal fossil fuels, petroleum, and Cement. iii. Radioactive or solar radiations from natural disaster contribute to the cause of global warming. 4. The Effects of Global Warming i. Basal temperature rise projection from 30C to 50C about century to come. The temperature rise causes latent heat expansion of the ocean leading to increase in normal volume by about 20 meters. There is death of aquatic life leading to water pollution, spread of water-borne diseases, and malnutrition. ii. Prevalence of drought, low rainfall, famine and low industrial energy input and output. Also, increase spread of epidemic plagues and other communicable diseases in an unprecedented rate. iii. There would be economic regression with insurance industries at larger risk. Africa stands the greatest economic risk because of Farming. Increase in cost of transportation maintenance, immigration and emigration from glacial shift. References Hegerl, Gabriele C. ; et al.

How the French Describe Clothing Shape and Texture

The French are specialists in great clothing  and  shoes. They differentiate them endlessly according to shape, texture and more. As a result, there are plenty of adjectives and expressions that are used every day to describe the attributes of clothing. Before using all these adjectives, it is an opportune moment  to review the basic rules of adjectives, what an adjective is and its grammatical behavior in French. Basic Rules for French Adjectives These terms  must follow the  basic rules of agreement for French adjectives. For example, if an adjective ends in a consonant, add an  e  to make it feminine, a silent  s  to make it plural. Adjectives are usually placed after the noun in French. Plus, the final consonant of adjectives is silent. It is pronounced only in the feminine when followed by a silent e. To modify fashion adjectives, the French commonly use the adverbs trop (too), pas assez (not enough) and vraiment (truly). The adjectives and expressions here are worth knowing, chiefly because theyll be incredibly useful in everyday life. Ironically, fashion is  the field where students lack vocabulary the most, even though it is a major theme in French conversations.   To remedy this lack, here are French adjectives and expressions commonly used to describe clothes. In every case, the masculine form is listed; the feminine form follows in parentheses only if the adjective  is irregular.
