Chalk Dust, Cinnamon Spice and Coffee Ground as Insect Repellants Essay Example for Free

Chalk Dust, Cinnamon Spice and Coffee Ground as Insect Repellants Essay BACKGROUND OF THE STUDY: There are several household problems we and our helpers encounter at home. These may be issues regarding food supply and storage, cleanliness and sanitation. One of the most common problems is the presence of household ants, especially the red ones, causing a disturbance in our own system of food storage. Red household ants do not only infest stored food in the kitchen but also bite our skin and destroy well- landscaped gardens by building ant hills. Because of this observation, we decided on conducting a study that would eliminate ants with the use of alternative substances that can also be found at home. With this study, we will not only discover other uses and benefits of household waste products but also provide new ways of promoting clean and sanitized homes by eliminating insects. Once proven effective, chalk dust which is one waste product in the classroom, will also be of good use at home. OBJECTIVE: The study aims to find more possible uses of household waste products aside from remaining as garbage such as coffee grounds, and discover further and effective use of chalk dust. Also, we aim to eliminate household insect especially ants that would cause a nuisance in our kitchen. DEFINITION OF TERMS: Talcum Powder- an ingredient in both chalk and baby powder, and is a natural ant repellant. Brewed Coffee- coffee produced from a process with the use of coffee maker wherein hot water drips onto coffee grounds held in a coffee filter made of paper, plastic, or perforated metal, allowing the water to seep through the ground coffee while extracting its oils and essences. The liquid drips through the coffee and the filter into a carafe or pot, and the spent grounds are retained in the filter. Coffee ground- is the used bitter powdered coffee that remains in a pot or coffee-maker after brewing your  coffee. HYPOTHESIS: All three substances tested will give significant results in repelling ants. VARIABLES: INDEPENDENT| CONTROLLED| * 50 grams of coffee ground * 50 grams of cinnamon spice * 50 grams of chalk dust| * Similar area where the three experiments will be conducted, same length * The same ant pathway where the substances will be placed * 1-3 tbsp. of sugar | Resulting Variable: Time it takes for the ants to move away from the repellants CHAPTER II RELATED LITERATURE Ant and Its Symbolism â€Å"Chinese consider and identified ant as the â€Å"righteous insect† and attribute orderliness, virtue and patriotism. On the other hand, Muslims consider the ant as the earthly teacher of Solomon and an embodiment of wisdom.† (Retrieved from http://sherryandrea.com/ant-symbolism-and-meaning/) http://www.jewishencyclopedia.com/articles/1570-ant-in-jewish-literature-the: â€Å"In the Old Testament, the Ant is referred to as some harvesting species which are to this day found in Syria and all around the Mediterranean basin. These species wherever they are found, as the latest investigations of naturalists have proved, lay up stores for the winter. In the Tamuldic Literature, The ant was mentioned being experimented by Simon ben Halafta to ascertain whether they inhabit without a ruler. Also, it was mentioned that ants procure food. There were also statements in the Book of Proverbs where it is pointed out that the wisdom of the Creator is manifested in the fitness of the body and wonderful life of the Ant.† â€Å"From a purely scientific point of view, the Ant is treated by Gershon ben  Solomon, in his work, â€Å"Sha’ar ha-Shamayim.† The Ant, he says, gathers its wheat in the harvest, biting off the germs of the grains in order to prevent them from sprouting and thus preserving them from rotting- a fact verified by recent observation. The Ant, he says further, is proportionately the strongest of all creatures, being able to carry from two to four times its own weight. Moreover, it can move both ways, forward and backward.† History of Brewing Coffee In the early history of coffee, the coffee beans were dried and eaten. By the 16th century, coffee was roasted before being ground and boiled in water. The entire resulting mixture of liquid and grounds would be consumed. The invention of the Ibrik (A small pot used in brewing and serving Turkish coffee that was invented in the late 16th century.) allowed for a more skillful technique of brewing. In the 18th century, the French developed the drip brewing technique wherein coffee is produced by using a cloth bag as a filter to separate grounds from the liquid coffee. This technique allowed for steeping the coffee at a lower temperature as it was not brewed while constantly adding heat. (Retrieved from http://coffee.wikia.com/wiki/Brewing) Chalk in Prehistoric Times As found in nature, chalk has been used for drawing since prehistoric times, when, according to archaeologists, it helped to create some of the earliest cave drawings. Later, artists of different countries and styles used chalk mainly for sketches, and some such drawings, protected with shellac or a similar substance, have survived. Chalk was first formed into sticks for the convenience of artists. The method was to grind natural chalk to a fine powder, then add water, clay as a binder, and various dry colors. The resultant putty was then rolled into cylinders and dried. Although impurities produce natural chalk in many colors, when artists made their own chalk they usually added pigments to render these colors more vivid. Carbon, for example, was used to enhance black, and ferric oxide (Fe 2 O 3 ) created a more vivid red. CHAPTER III METHODOLOGY 1. Gather the variables needed. You can find cinnamon spice in your kitchen. If not, you may use any spice available (e.g. pepper, black pepper, garlic). Collect coffee grounds after brewing coffee with the use of a coffee maker. Collect chalk dust from other classrooms. Measure the quantity and make sure that each one reaches the same amount- 50 grams. 2. Choose an area at home where you can find an ants’ pathway and measure its length. This will also be one of the controlled variables in the experiment. 3. Make sure that there are ants present. If none, place a few pinches of sugar or food crumbs to attract the ants. 4. Once the ants are present, choose among the three substances to be placed first along the path and put it evenly making a thin line. 5. Record the time it takes for the ants to leave the place. 6. Repeat steps three to five with the use of the other two substances and record the results on the Table of Data and Observation below. You may also take pictures du ring the experiment.

Scene Analysis of Alfred Hitchcock’s Film Shadow of a Doubt Essay examp

Scene Analysis of Alfred Hitchcock’s Film Shadow of a Doubt Alfred Hitchcock’s film Shadow of a Doubt is a true masterpiece. Hitchcock brings the perfect mix of horror, suspense, and drama to a small American town. One of the scenes that exemplifies his masterful style takes place in a bar between the two main characters, Charlie Newton and her uncle Charlie. Hitchcock was quoted as saying that Shadow of a Doubt, â€Å"brought murder and violence back in the home, where it rightly belongs.† This quote, although humorous, reaffirms the main theme of the film: we find evil in the places we least expect it. Through careful analysis of the bar scene, we see how Hitchcock underlies and reinforces this theme through the setting, camera angles, and lighting. One of the most important elements of this scene, which can be overlooked, is the setting. An unpleasant confrontation between the protagonist and antagonist takes place inside a bar of all places. This scene is crucial because it is the first time we are completely taken into Uncle Charlie’s world. The bar acts as a liminal space for the audience to enter into his personality. It is also the first time the two main characters have a confrontation about Uncle Charlie's dark life. It should be noted that until this point most of the scenes between the Charlies have been in domestic and safe places. The bar is a complete contrast to Santa Rosa’s all-American values and standards. The director most likely set this conversation in a bar because of the negative connotations that are associated with such a place, which perfectly match the personality of Uncle Charlie. The setting also underlies the menacing nature of the conversation between the Charlies. Just as the setting is importan... ...ing Charlie's close-ups portrays a delicate glowing face, which appears frightened and angelic, an obvious contrast to the shadowy right side of her Uncle's face. The lighting scheme on the Uncle's face is a classic cinematic device revealing the duality of his personality. And again we are brought back to duality, one of the most popular themes among this director's films. Through his choice of setting, camera angles and lighting, Hitchcock makes the conversation at the bar a pivotal scene. The audience and young Charlie are finally brought into Uncle Charlie’s world. This scene’s contrast to the stereotypical American town is what makes this scene so important. Even though Uncle Charlie was able to conceal his true self from most of Santa Rosa, a few people saw him for what he really was. Just like there is a bar in every American town, there is evil as well.

Autism a Communication and Social Disorder

Autism is a brain disorder that is characterized by impaired social interaction and delayed communication skills. (Segal, 1996) Children with Autism show signs of delay in the first two years of life. Many times parents notice that their child demonstrates repetitive behaviors, or likes to spin objects, line things up or has an affinity for sameness. Some children with Autism have difficulty with transitions from one activity to another and are not able to regulate their senses. The range of these behaviors varies and that is why Autism is called a spectrum disorder. Many times, children will exhibit one or several of the symptoms. Children who exhibit fewer symptoms are diagnosed with PDD or Pervasive Developmental Delay, while children who have many of the symptoms are termed Autistic. There is recent research that shows that autism may be caused by genetics which are related to how the brain develops in early childhood. In the article, Autism and Brain development, Nancy Shute reports that some kind of mutations of genes that are important to language development may be the cause of autism in some children. Daniel Geschwind is researching the fact that these genes are sometimes turned on or off depending on the brains experiences. † (Shute). There is also a chance that â€Å"structural damage will be found, and this damage could be anything from microscopic to the grossly visible, from faults inside nerve cells to faulty development of whole cell systems. † (Frith) The causes of Autism are still being explored, but the more important thing is how people are diagnosed and treated for it. The symptoms of Autism are variable, and usually different in each child. Delay of language development, lack of social skills and lack of eye contact are a few of the symptoms. Because there is a range in the severity of the symptoms the diagnosis and treatment of autism varies and is an interesting process. The diagnosis of autism is based on a behavioral check list. â€Å"Because a diagnosis is a label or shorthand for treatment, it needs to correspond to the services to the child needs in the immediate future. † (Siegel) The parents, teachers, developmental pediatrician and sometimes other therapists all contribute to the assessment. The CHAT, Checklist of Autism in Toddlers is one way that pediatricians screen children under 2 years old for Autism. For children 4 years and older, a Social Communication Questionnaire is often used. These screenings rely on parent report and the observation of a diagnostic team. Then the child will be referred to a developmental pediatrician or a psychologist who is trained in diagnosis of Autism. There are several diagnostic tools, usually developmental checklists, and parent report along with a team of professionals who look at the behavioral symptoms that are characteristic of this disorder. The team of professionals who diagnosis autism typically include the parent, speech therapist, teacher, pediatrician and occupational therapist. The most widely used diagnostic tool for Autism is the ADOS, (Autism Diagnostic Observation Schedule). The North Bay Regional Center uses this to diagnose children with autism in this area. There are also other centers, the Mind Institute with is part of the University of Davis medical Center, where they focus only on diagnosis of Autism spectrum disorders. Bryna Siegel is a Psychologist who works at UCSF and has her own diagnostic clinic. Each case of autism has its own individual characteristics ranging between its cause, its diagnosis and the life long treatment. After being diagnosed, different therapy options are presented; PECS, play therapy and discrete trial are the three more commonly used treatments. What is best for children with Autism is an early diagnosis, and intensive speech and language therapy which includes the family. Dr. Stanly Greenspan has developed the â€Å"Floortime† approach to helping families learn to interact with their children. â€Å"Autism and ASD’s involve difficulties in relating forming relationships, communicating, and thinking. (Greenspan) Play therapy also gives parents a chance to learn to communicate nonverbally with their autistic child. One of the most effective styles of play therapy is called floor time. â€Å"In playing with their child, parents can help her develop her social skills and also connect with their child through this nonverbal style of communication. The floor time/play therapy that a speech therapist directs is used to â€Å"harness the child’s natural interests. † (Greenspan) in doing so they are able to â€Å"get a picture of what she finds enjoyable, what motivates her. (Greenspan) and is considered as the best method for supporting the language and social communication development of the child with autism. Speech therapy is one of the most important pieces of the team approach to help children with Autism develop social and communication skills. The goal of speech therapy in working with children with autism is to help the child communicate her needs and wants. A specific therapy program is individualized for each child. There are as many programs as there are children. There are a wide range of therapies that facilitate language development in children with Autism. Normally language and play go off one another when both are impaired; they are likely to mutually inhibit the development of the other. † (Siegel) While there are other therapies, play therapy is considered one of the most effective ways to understand nonverbal communication in autism. Children with Autism can benefit from play therapy. The therapy is based on the child’s own interests. Children with autism do not play with toys in a functional way. â€Å"One thing that is often different about the sensory development of autistic children is its repetitiveness. This is also referred to as perseveration. Instead of pulling a string or handle on a â€Å"speak and say† five or six times, the autistic of PDD child may engage in such an activity for 20 minutes without stopping. † (Siegle) Play therapy teaches the child to play with toys in ways that use imagination and are symbolic. And since imagination is obscured in autistic minds this is very important. Even though it may not be clear in a young child it can be observed in some situations such as a â€Å"Two year old autistic children (who) ‘play telephone’. They pick up the receiver and punch the buttons on the toy phone. Then they put the receiver down, less often will you see the autistic two year yammering, as if talking to someone. What is really never seen in the successive ‘calls’ – say to grandma, big bird, or the family dog. That type of elaboration on a toy thing is beyond the slope of imagination of most autistic children instead, the physical actions copied strictly from what has been observed in the past is playlalia. † (Siegle) Play and speech therapy, paired with pictures is one of the ways that speech therapists and parents encourage language. Often the child with Autism uses a picture to exchange for a desired item this is called PECS. This picture exchange system is important and can be used after observing and playing with the child to determine what toys the child is interested in. It is used as a stepping stone for communication with the outside world. The picture exchange system is a way for children with Autism to communicate using pictures. This is a good way for them to make their needs and wants met. Many children with autism have tantrums or do not want to cooperate with their teacher or parents. The best way to find out what a child with autism wants is to use this simple system. Since many people on the autism spectrum tend to learn visually, it makes good sense to communicate with images. Just as important, images are a universal means of communication – and they are just as understandable by strangers or young peers by parents or therapists. † (Rudy) When the parent knows what the child wants, they can use the picture of the desired item as a reinforcer to help the child cooperate with the parents directions. Sometimes the parent will offer the child two pictures as choices. Other times the parent can use the picture of an activity that needs to be accomplished and a picture of a desired item. Then the parent can say, first wash hands and then you can have bubbles. The child learns this routine and is able to communicate, and follow the parent’s directions. There is a more complex style of picture exchange system where the speech therapist starts with one item paired with an object. The speech therapist then asks the child â€Å"want cookie†, showing the child a picture of a cookie and the cookie. When the child understands that the picture represents the cookie then the child is ready to use the pictures for other choices. Later the child is using pictures to help form sentences. There are many ways that speech therapists use pictures to encourage language. Often the speech therapist works with the behaviorist to develop a system that will provide reinforcers for the child. These reinforcers help the child to stay motivated during therapy. The behavioral therapy or Discrete Trials therapy is often used along with speech therapy. â€Å"Discrete trial training is conducted using intensive drills of selected materials. A specific behavior is prompted or guided, and children receive reinforcement for proper responses. † (What is Discrete Trial Training? This is a program that teaches a child with autism specific information in small units which are less distracting for the child. Because children with autism are so distractible or may want to obsess on spinning or other behaviors, the discrete trial helps them to focus on learning vocabulary, names of animals, math and pre reading skills. The occupational therapist is also important to the treatment of children with Autism. This therapist often uses sensory integration techniques to help the child with Autism develop self regulation. Many of the children with autism have self stimulatory behaviors with are sometimes their way to regulate, their senses. These self stimulatory behaviors may not be as effective as the specific movement, vestibular, or deep pressure, proprioceptive, or sensory, touch and brushing that the occupational therapist uses. The parents of the child with autism are invited to observe what the therapist recommends, and then they can use many of the recommendations at home to help calm their child. Many children with autism are sensitive to loud noises, and are sometimes very sensitive to tags in the back of their shirts, or the seams on their socks. The book, â€Å"The Out of Sync Child† by Carol Stock Kranowitz, has many suggestions for children who are sensitive to noise, light, and touch. The research is clear that the first step is early intervention using a team approach early diagnosis and treatment specific to the individual child is the most helpful thing you can do. Although it takes patience and understanding (with the trial and error); with the numerous treatments available every child can be helped. The diagnosis is the first step, and when treatment is started early, the team approach is the beginning of optimal treatment for the child.

Kennedy The 35th President of America" essay for you Create order history have been assassinated, John F. Kennedy is well known for many events such as Cuban Missile Crisis, the Nuclear Test-Ban Treaty, the Alliance for Progress and his own assassination. After President Kennedys assassination on November 22, 1963, Dallas people have faced troubles while traveling around the country for many years. Sometimes, because of their origin, people denied to service them. The book Dallas 1963 written by Bill Minutaglio and Steven L. Davis a mesmerizing piece of work about all the problems that go around that times. I will examine eight points based on the book Dallas 1963. Dallas, Texas was founded in 1841 has become one of the largest metropolitan areas in the Southern United States. However, back in the 1960s, Dallas is not as open as it is today. During this time, Dallas was full of racism and there are many combining angry forces in Dallas and throughout the South. The authorities such as governors, senators, even the mayors still rally to resist many things: the revolutionary integration edicts ordered by federal government, by the Supreme Court, by political forces in the North, and so on. Almost Dallas people are innocent and a bit of nave, hopeful, and ill-informed. They are looking for someone or something that will give them a purpose of life. The leadership in Dallas fear communism, civil rights, and particularly John F. Kennedy. Because to most of them, President Kennedy was viewed as a danger in the Southern of United States, not because he was potentially soft on communism but because of the civil rights issue. Most of Southerners in 1963 still belonged to Democratic Party. Therefore, the Dallas people in the opposition of President Kennedy. In fact, contradicted feelings toward him in Dallas and among southern white people generally. Martin Luther King was born and raised in an activist family. Therefore, his view about the society has a great influence from them. By 1960, the Civil Rights Movement had obtained strong momentum thorough the South. Martin Luther King Jr. employed nonviolent measures which helped African American activists win supporters across the country and throughout the world. Because the leadership in Dallas want to keep the same way as it was. They dont want equal between white and black men. They want more inferior the black people and MLK was stopping it from happening. He demands for equal rights between American people without distinguish their race or the color of their skin. Martin Luther King dedicated his life to make it easier for his people and many others, and he died because of that effort. As Holocaust survivors who immigrated to the United States after the war, many people in indignant about discrimination in this country. The sting of personal discrimination parallels disgust with segregation and institutionalized racism in the United States and motivates many people to work to end it. Some of them participated the Civil Rights movement, influenced by the fresh wound of the Holocaust, earlier pogroms, and everyday discrimination. Holocaust survivors fear the direction that Dallas was taking because Dallas in the position of hated and discriminate the holocaust. Dallas has many peculiar personalities that attracted many people. During the 1950s and 1960s, Dallas became one of the third largest technology centers. Which grew into the Dallas Market, the largest wholesale trade complex in the world. It is the place of job opportunities and evolution, especially in the metro industry. Dallas was also the top job generator in the country. There were about three hundred thousand people from different states that migrated here every year. The President described his visit to Dallas as a visit to the nut country. The President was aware of the people in Dallas and its leadership and in particular the hostility that they harbored against him. He knew that they were capable of anything given the fact that the city was taking a direction that was so different from the rest of the country. The city was also corrupt and divided and to a point referring to it as nut country was rather accurate as it denoted crazy. Crazy Town would be a perfect respond for Kennedys saying. It would be accurate to state that Dallas was indeed responsible for the assassination of President John F Kennedy. The president was shot in Dallas by Lee Harvey Oswald but the city in itself was so poisonous and resentful against the president that collectively it can be stated that it was responsible for the assassination. Societal attitudes in Dallas back in the 1960s is the opposition of Kennedys presidency. Because he supported the Civil Rights movement alongside with Martin Luther King. Dallas, Texas has always been a conservative city and was against the Civil Rights movement. They show their hated and protest against the Civil Rights movement. In the 1960s, we start to see it shift towards being a progressive and desegregated area. Time changes, societal attitudes also change. Dallas is not as it used to be anymore. The people became more and more innovative thinkers than ever before. Not only in Dallas but also in the United States as well. Dallas has made a start and there is a challenge to keep moving forward. In conclusion, there are many reasons and theories that go around President Kennedys assassination and why Dallas dislike him so much. Based on the book Dallas 1963, eight points of view that are presented explain those reasons. Overall, President John F. Kennedy is a man that mean to be respected not only for his legacy but what his doing to make every American people live in equally and independently in society.
