Scientific Investigatory Project free essay sample

Most people grew up and lived with the electric currents flowing through the wiring within the walls of their homes. They helped us a lot everyday besides giving energy to power appliances at home such as television, computer, radio, video games. Electricity keeps more important appliances like gas stove, refrigerator, air conditioners which we all need to lessen and help us in our work and in life. Thus having power cut tends to create confusion and panic in homeowners who are unprepared. The continuation of power outages due to widespread power failure can not only be inconvenient and problematic, they can be dangerous and can create troubles and accidents for people who depend on power to operate appliances and medical devices within their home. A generator can keep your appliances that require electricity at home functioning normally and your family can continue on their routine. They also help maintain a safe and well-ordered life in the midst of possible chaos and accidents.

Visible Light Spectrum Overview and Chart

Visible Light Spectrum Overview and Chart The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10-7 m, which is red). It is also known as the optical spectrum of light or the spectrum of white light. Wavelength and Color Spectrum Chart The wavelength  of light,  which is related to frequency and energy, determines  the perceived color. The ranges of these different colors are listed in the table below. Some sources vary these ranges pretty drastically, and their boundaries are somewhat approximate, as they blend into each other. The edges of the visible light spectrum blend into the ultraviolet and infrared levels of radiation. The Visible Light Spectrum Color Wavelength (nm) Red 625 - 740 Orange 590 - 625 Yellow 565 - 590 Green 520 - 565 Cyan 500 - 520 Blue 435 - 500 Violet 380 - 435 How White Light is Split Into a Rainbow Most light that we interact with is in the form of white light, which contains many or all of these wavelength ranges. Shining white light through a prism causes the wavelengths to bend at slightly different angles due to optical refraction. The resulting light is split across the visible color spectrum. This is what causes a rainbow, with airborne water particles acting as the refractive medium. The order of wavelengths can be remembered by the mnemonic Roy G  Biv for red, orange, yellow, green, blue, indigo (the blue/violet border), and violet. If you look closely at a rainbow or spectrum, you might notice that cyan also appears fairly distinctly, between green and blue. Most people cannot distinguish indigo from blue or violet, so many color charts omit it. By using special sources, refractors, and filters, you can get a narrow band of about 10 nanometers in wavelength that is considered  monochromatic  light. Lasers are special because they are the most consistent source of narrowly  monochromatic light  that we can achieve. Colors consisting of a single wavelength are called spectral colors or pure colors. Colors Beyond the Visible Spectrum The  human eye  and brain can  distinguish many more colors than those of the spectrum. Purple and magenta are the brains way of bridging the gap between red and violet. Unsaturated colors, such as pink and aqua, are also distinguishable, as well as brown and tan. However, some animals have a different visible range, often extending into the infrared range (wavelength greater than 700 nanometers) or ultraviolet (wavelength less than 380 nanometers). For example, bees can see ultraviolet light, which is used by flowers to attract pollinators. Birds also can see ultraviolet light and have markings visible under a black (ultraviolet) light. Among humans, there is variation between how far into red and violet the eye can see. Most animals that can see ultraviolet cant see infrared.

Boeing Innovation article Essay Example | Topics and Well Written Essays - 250 words

Boeing Innovation article - Essay Example The Boeings decision to seek an alternative strategy was significantly based on the changes that the industry is undergoing. The current airline market is not willing to pay more for new and more advanced technologies. Because of this, the company’s strategy of saving up a number of advanced technologies for one project became disruptive and too expensive. Boeing previously adopted an incremental strategy. The approach proved costly as the company lost its market share to rival company Airbus Group NV (Ostrower 2015). A new approach was needed. The changes made on its approach extend to all Boeing’s operations. Suppliers’ contracts that represent approximately sixty-five percent of the total cost of its planes are being renegotiated. In the process of aiming for better, faster and cheaper production, the company hired Walter Odisho as head of manufacturing. Mr. Odisha was previously the head of Toyota Corp.’s. Boeing also looked for inspiration from the Toyota Company on how to automate its production. The company says these efforts have helped it save up to one billion last year (Ostrower

Linking observation of children to developmental theory and policy

Linking observation of children to developmental theory and policy Written Report Linking Observation of Children to Developmental Theory and Policy Watching and listening to children is an important part of a Nursery Practitioners role. This is how we learn what stage of development a child has reached. Bowlby states â€Å"a further principle of the theory of learning is that an individual cannot learn a skill unless he has a friendly feeling towards his teacher.† (pg65) Observations enable you to compare to the expected development milestones which are the basis of our Social policy they are Practice Guidance for the Early Years Foundation Stage and the Every Child Matters documents. As all children develop at their own pace, there are influences that affect the rate at which a child develops, and these are environmental and also genetic. A childs surroundings, their family, and culture are very important in placing particular emphasis on some aspects rather than others. Rousseau proposed† that development proceeds according to an inner, biological timetable; we have a picture of development unfolding fairly independently from environmental influences. Children are no longer simply shaped by external forces, such as adult teachings and social reinforcements. They grow and learn largely on their own, according to natures plan. We call this method â€Å"Biological Maturation.† Within the first week of a child starting in the nursery setting, an initial child profile checklist is carried out. This profile gives the basis for the key person to discover at what stage of Early Years Foundation Development the child has currently reached; it also aids the key person in planning activities to assist in the childs development in moving on to the next stage. Practitioners will also be able to see any child development concerns. This can assist the key person in devising an individual educational plan if necessary. The methods of observations used for this report are a Sociogram and a Developmental Checklist. However these observations are only a snap shot of the overall development of the child. The aim of this Sociogram is to discover what child As interests are; who she interacts with; and what stages of development she has reached. Art Area Painting Choosing painting Putting apron on correctly Asking for help Painting lines and circle Writing L for name Speaks to child B Home Corner Dresses doll Speaks to doll Has conversation with child C explains what she is doing Book Area Talks to staff about rules Speaks to child D and E about rules Reads story to two children. The checklist focuss on the physical and intellectual development of child A as we can see from the checklist, the childs physical development is on line with the milestones stated. Also intellectual assessment is on line with Early Years Foundation Stage and Mary D Sheridan From birth to Five Years. E. Y. F. S.

Advantages and Disadvantages The methods of observations used had advantages and disadvantages the Sociogram disadvantages:- Subject to considerable distortion. Another child may need your attention; therefore you may have to stop and start again. Also another member of staff can not take over form you. A lot of language can take place which is not obvious in the Sociogram. Not explanatory for parents. Advantages:- 1.

A lot of language can take place which is not obvious in the checklist. Parents can miss interpret results. Information is closed data. Advantages:- You can put checklist down and return to it later. Quick and easy way to record. Any colleague can take over from you. You are able to identify a need while you are doing this. Does not require completion in one day. Does not require to be filled in the order given. Its an on going profile for the Early Years Foundation Stage Development. Evaluation The milestones for a four year old (Sheridan) states â€Å"walks up and down stairs alone one foot to a stair and matches and names four primary colours correctly† (pg 55); child A is 3 years 3months. This shows us that she is above her milestone development. Child A interacts well with staff and relates well to her peers; she thoroughly enjoys books and taking the lead and reading stories to her peers; a lot of the time from memory. The information gathered does not give a holistic view of the child but of her performance on the day the observations were carried out. Conclusion As we have assessed child As milestones through the observations we now know that she has reached the milestones relevant for her age range. We also note that she has reached several developmental milestones in the next stage of her development. Other methods of observation used in the setting are Target child and Time sample along with photographic observations. We know that childrens development is not straight forward and that they all develop at a different speed, so for the practitioners to be able to monitor these milestones they need to have the knowledge and social policies in place to be able refer to them. Sharman, Cross and Vennis say â€Å"The most appropriate way to monitor progress and compare it with what we are learning, or know, about the way children and young people mature and develop, is to understand observation.† ( Sharmon C, viii 2006 ).

Essay --

Introduction Participation in sports for children and youth is ever growing and there have been many benefits associated with it, including self-confidence and self-esteem, social and life skills development and improving mental and physical health. (Allender et al., 2006; Coplan & Findlay 2008; Donaldson and Ronan, 2006) Apart from these benefits, advocates of sport participation believe that sports provide the appropriate context for social and life development skills, which brings about the idea of character development through sports participation. (Weiss, Smith, & Stuntz, 2008). Life skills as suggested by The World Health Organization (1999), play a very important role in the healthy development of adolescents, as it helps prepare them for their future. The use of sports to help with such development is further supported by sport psychologists whom have argued that life skills can be taught in combination with athletic skills in sport contexts (Danish & Nellen, 1997). Sports has been thought to be a platform whereby children and youth are able to learn and cooperate with their teammates, develop self-control, display courage and leadership, communicate and form solutions to internal or external group conflicts and the learning of good virtues such as teamwork, fairness and good work ethics. (Shields & Bredemeier, 1995; Weiss & Bredemeier, 1990). Many parents therefore encourage and enroll their children into sports in hope that they will be able to learn and pick up these positive character-related values and behaviour. On the other hand, there have been other studies to argue the fact that sports instead of developing character, it undermines character. (Bredemeier, 1985, 1994; Bredemeier, Weiss, Shields, & Shewchuk, 198... ...certain behaviours which they interpret as being able to gain praises from their coach. As such, the way in which coaches verbalise, comment and teach the rules of the game to their players, will ultimately determine the way in which the players will interpret and act upon the rules during game play. (Bar et al., 1989) With the increasing number of primary school students taking part in sports, sport can present itself as a great platform for character development; but the positive outcomes are not always guaranteed. A coach who is able to capitalise on this invaluable and unique platform to inculcate good values is essential in order to ensure positive character development outcomes. This study aimed to describe and analyse a successful primary school netball coach's experiences, strategies and the desired outcomes for athletes as a function of her coaching.
