Insect Repellant

Introduction A. Background of the Study For us, a house is a place of residence. It is usually a place in which an individual or a family can rest, store personal property, and prepare food. In able for the house to fulfill its function, we need to eliminate some factors that disturb us in doing these things. One example is the insect. One of the easiest ways to prevent insects is to use insect repellant. This is the reason why I decide to make a liquid insect repellant for my Science Investigatory Project. There are many commercially available liquid insect repellant in the market.The commonly used commercial liquid insect repellant in the Philippines is quite unaffordable and use chemical that may cause irritation. I plan to use natural ingredients in my Science Investigatory Project. Since the ingredient to be used is natural, the liquid insect repellant to be made is more affordable and environment friendly. B. Statement of the Problem Is it possible to make an effective liquid r epellant out of cacao leaves, garlic, vegetable oil, and eucalyptus oil? If it is possible, how is the price and effectiveness of it comparing to the commercially available one? C. Significance of the StudyThe study is significant to the people who want to protect their house and their love ones against insects specially those who cannot afford the commercially available insect repellant which uses chemicals. Chapter II : Review of Related Literature Chemical Repellants It is no wonder that, considering all of the above mentioned diseases, humans have worked for decades searching for a way to repel these insects. In 1946, a chemical called DEET (N, N-diethyl-m-toluamide) was developed by the US Army and released for civilian use in 1957. DEET confuses the receptors of most biting insects, rendering them virtually ‘blind’ and thus much†¦

Essay about Autism Educational and Social Effects

Autism: Educational Social Effects nbsp;nbsp;nbsp;nbsp;nbsp;As a student living with no impairing physical or mental disability, it is difficult to imagine life any other way. On the other hand, when taking the time to contemplate what people with disabilities, such as Autism have to cope with, I realize just how much I take for granted in every day life; such as options to any class, learning at a normal pace, and peer interactions, to name a few. Autism not only affects people physically, but socially as well, ensuing subordinate self esteem, meager social skills, and poor peer relationships, aspects of maturing which are crucial to proper development. nbsp;nbsp;nbsp;nbsp;nbsp;A child with disabilities is presented with two†¦show more content†¦Many parents even felt inclusion was a violation of their rights to be thoroughly involved in the planning and decisions of their child’s education process (Wong 3). But what do the children think? nbsp;nbsp;nbsp;nbsp;nbsp;A case study was conducted by Brenda Myles and Richard Simpson on the behavior and interaction of children with Autism when integrated with children of normal learning abilities. They integrated four children into an all autistic classroom, and monitored behaviors such as asking questions, requesting help, social interactions, aggression, complaining, and frustration (Myles, Simpson 5). The results were clear. When given the opportunity, Autistic children socially interacted with others 54% of the time when normally developed children were present as opposed to 71% of the time when it was just the Autistic children, they were obviously intimidated (Myles, Simpson 5). There was also 21% more assistance provided to the children with Autism when their peers were in the room, as well as a higher rate of complaining, aggression, and frustration (Myles, Simpson 5). One has to wonder the effects this will have after years of integration. Merely because of their dise ase, there is no way for them to normally interact with their non-disabled peers in a school related environment without feeling higher levels of agitation, frustration, and intimidation.Show MoreRelatedHow Communication Is Difficult And Interacting With Others954 Words   |  4 Pagesscale from what we have learned the past few decades a child who is on the spectrum of Autism may understand the words, but not the music.
