Pacific on Science Learning and Teaching Essay Example

Pacific on Science Learning and Teaching Essay A journal entitiled Asia – Pacific on Science Learning and Teaching (APSLT) stated that many students have misconceptions regarding floatation or â€Å"sink or float phenomena.† Misconceptions probably arise due to certain observations that deviate from scientific laws.(Problematic issue for students: Does it sink or float? June 2005) Possession of these misconceptions can lead to learning problems.(Science Misconceptions, 2005)Misconception on floatation occurs because this concept involves complex reasoning. The presuppositions regarding the sink or float phenomenon is identified based on the test conducted by the institution on elementary students. The test includes a twenty – item multiple choice Sinking and Floating Conceptual Test.(Problematic issue for students: Does it sink or float? June 2005)   Based on the obtained results, certain misconceptions on factors that determine whether an object will sink or float are the mass or weight of an object, the v olume of an object, and the amount of water in a container. Also, it was observed that prospect students have a hard time understanding density.One of the major factors that can determine whether an object will sink or float is its density. Density is defined mathematically as mass per unit volume, kg/m3.(Density, October 2005) It is unique for every material. The density of many object are compared to the density of water. If the density of an object is less than the density of water then that object will float, otherwise it will sink.(Ophardt, 2003) Oil is less dense than water, so it must be expected that oil will float in water. Density must not be referred as the weight of an object or its mass or even the force that pushes the object up. Clearly, it is not the mass or volume of an object that determines if it will float or not, but rather, the combined ratio of this fundamental units.Mass and weight cannot be interchanged or be confused of. Mass is constant for a certain matte r, however, weight is only proportional to the mass of the body and is also dependent on its location in the universe. It is location dependent since it is also proportional to the gravitational force exerted on the body.(Ophardt, 2003)The upward force that pushes the object up is referred as buoyant force. An object floats because the buoyant force exerted on the body is greater than the gravitational force. If an object floats in a fluid, then the buoyant force is just equal to the weight of the liquid that is displaced. This principle is formulated Archimedes. However, if a certain object sinks in water, then the weight of the object is equal to the buoyant force exerted on it.(Kurtus, 2003)It can be said that a stuffed animal will float when immersed in water because its density is less than the density of water. Same reasoning can be used to explain why styrofoam can float in water. Lastly, a cardboard will not float in water due to its ability to absorb water.To avoid the pre- said misconceptions certain conditions must be achieved.   First, concepts such as density, mass, weight must be clearly explained.(Kurtus, 2003) Experiments must be employed. This experiment must allow one to determine whether an object will float or not accompanied with proper scientific explanations. This experiment must allow one to determine the characteristics of an object that floats and objects that sink. One must develop the thinking that it is not only the weight that determines if an object will sink in a fluid.(Sink or Float? 2006) Also, different factors that determine whether an object will sink or float must carefully be studied.

Communications essays

Communications essays When our group started picking out a project we were going to do an experiment. But, then we thought about it and the more we did we decided that it would be better to give back to the community. So, we sat down and looked around to see what we could do. We decided that we were going to give back by donating out time to people that needed that extra bit of support. We decided that we were going to become volunteers for a day at the Special Olympics. As I look at our group I see that there is no clear leadership role that was shown. We all had a part in the research, planning, and implementation of the project. However, there are two figures that stand out a bit, Nancy and myself. She had the leadership role in the original planning stage of the project. She was the one that brought forth the idea for the Special Olympics. However, I was the one that organized the meeting locations and times. The others all did their parts to the fullest. Jen, Frank, and Edwin did their best to put together the power point presentation that was planned originally. Ava and Jasmina both did an excellent job with the photography part of the project. We all became leaders in the assigned roles that we played, so this project would not have been a success without the cooperation and dedication that all the team members put forth. Individually we would have been great, but as a team we were awesome. For many of us this was a first time experience in a project like this. Along the way we hit quite a few bumps. We were disorganized at first and didnt know what we were doing. But as we sat down to brainstorm, our critical thinking skills took over. We were able to solve many problems that came along the way through group communication. A big problem that hit us was that we placed a huge chunk of our presentation to be implemented and demonstrated to the class to through the power point presentation. The night before the presenta...

Argumentive Essay The Myth of Media Violence Research Paper

Argumentive Essay The Myth of Media Violence - Research Paper Example in television programs as well as music videos that are obviously not meant for innocent children and accordingly, convey negative messages to the children whenever they happen to encounter them. These programs include but are not limited to negative reality shows, crime reports, adult movies and vulgar fashion shows. Such programs have caused the children to mature before the right age and they know too much for their age and mental capacity. A lot of people deny the difference between the extremity and intensity of negativity of the programs projected on television in the 1950s and those shown today by arguing that violence has always been there in the television programs, particularly in the bull fighting and wrestling. However, what I feel lacking in his argument is a realization of the fact that today’s media is far too open towards vulgarity and adultery contrary to the standards that were followed half a century ago. Any argument in favor of the violence and porn projected in the movies, video games and media today is, to me, illegitimate and irrational. It is an established fact that many music videos released nowadays are full of sexually explicit material. In fact, eroticism has become a fundamental trait of profitable music videos, particularly when they star famous celebrities. People are curious to know who has exposed to what extent. (Lewis 94) says that music slowly penetrates so deep into the social setup that it ultimately develops the tendency to overtly express the hidden belief systems that have long remained taboos in the society and hence, alters the society’s way of thinking and its lifestyle. (Lewis 94) further notes that in this way, music serves as the advertisement for the social belief systems that have not been discussed openly in the past, yet have existed in all times. Having watched the taboos openly discussed in the reality shows telecast, people become immune to them and stop shying about discussing matters and watching the

Waiting for the phone call

The room is stuffy. It has a gaudy lino floor with pattern rubbed away in front of the sofa and round the table; the walls are damp and cluttered with old calendars and pictures torn from magazines. There is a rotten stench. The mantelpiece by the fireplace is filled with china ornaments: big-eyed flop-eared rabbits and beribboned kittens and flowery milkmaids and a porcelain doll wearing a Victorian dress and her long, golden hair in two neat plaits. The room is silent; except for the steady paced ‘tick-tock' from the ancient Grand-father clock. It is Dorothy's birthday, 12th August. She is hunched up on her old tacky sofa on an early August morning. Dorothy is startled by birdsong echoing across the garden outside and, for a long time, she stares in confused remembrance towards where the swelling orange sun is burning the faded floral wallpaper across from her old-fashioned table. ‘It's my birthday,' she finally realises. ‘I'm seventy-six today. Where did it go?' Climbing painfully from a lumpy sofa, standing in a striped night dress by the window, Dorothy stares outside in her back garden. There's much too be done. Later. Much later. These days it's all weed killing, backache and sore bones. ‘It's my birthday.' Dorothy's cat slithers past a glass sharp wall and drops beside its shadow under an apple tree, stalking anxious sparrows. Under the broken birdhouse a mouse plays with a nibble of yesterday's bread. Shadows shrink in bright shyness against all the garden fences and the last star melts into dawn rise. There's heat in the breathless August day already. Dorothy sits in her kitchen. Silent. The house, holding its breath around her, the roof heavy and oven baked. Dorothy's thick veined hands brush toast crumbs from the plastic tabletop and when she moves her faded dainty feet dust dances giddily on the sun patched carpet. She listens to the awakening of the new day: the clock on the dresser ticks hurriedly and the letter box snaps awake. Dorothy walks to the hall and picks up bills and ads that promise discounts and holidays abroad, Dorothy has never been out of England, never been on a plane. Her tired eyes examine the envelopes at arm's length. There are no birthday cards to sigh over – Not even from her family! Returning to the familiar kitchen she slides a knife along her letters, slitting out the folded information. It's better than nothing. Even if the electricity is red and overdue – At least, they keep in touch. No longer absorbed in her letter opening task Dorothy looks at the sunlight shining blindly on her glazed, brown teapot and then she pours some lukewarm tea. She sits and thinks about birthdays back then – Cakes and drinks, songs and celebrations and her precious beloved family members spending time with her on her special day. Back when. ‘Time flies,' she says. She's talking to herself most days – who else will listen? Up in the still shadowed parlour a clock chimes the hour and Dorothy rises tiredly and prepares to face the day. She stumbles into the living room and looks up to the mantelpiece. No birthday cards – Only a picture of her and her adorable grandchildren, Steven and Carol. Her eyes close. She becomes delirious with dreaming†¦ Carol skipping up the lawn with a small straw basket, picking up little daisies and carefully placing them in the basket. Steven, being 2 years old, filling the bird house with crunchy treats awaiting the magpies to glide in. Dorothy is stood under the apple tree, tip-toeing up and grabbing fresh, ripe apples for her relatives. Carol and Steven run over to Dorothy and wrap their arms tightly around her as if they were to never let go†¦ Dorothy smiles and wishes she could still feel their small hands around her waist, grabbing securely. She dresses and walks to the front door and checks the windows and the bolts and all's secure. When the night time house creaks with its own age, Dorothy thinks of burglars and imagined violations and trembles in case they invade her. Dorothy swings open the front door and sees Carol and Steven stands there, smiling like sunlight. ‘Happy birthday Grandmother!' No longer astonished, Dorothy smiles back and sighs because they aren't really there. Her head sinks and she wonders back to living room. She notices the phone on the table. She slides over to it. Gently picks it up to check if the dial tone is there – she is reassured and drops it down. No phone calls. No phone messages. No birthday cards. She collapses into her tacky sofa. When she turns on the television the news assaults her soul. The world is littered with dead children and pain. The world has gone mad with cruelty and nobody seems to have noticed. It was different back in her day, when children could go out and play happily on the street without anybody worrying that someone would come abruptly attack them. Back when. She is startled by the sharp ringing of the phone. Her heart is pounding – could this be the phone call she has been waiting for all day? Is this her treasured family? She reaches over and clasps the phone. ‘Hello?' she asks waiting urgently for answer. ‘Hello. My name is Abigail Taylor calling on behalf of†¦' the woman replied. Dorothy slowly lowers the handset and replaces it back in the holder. She stands there paralysed. A tiny tear drop trickles down her wrinkly skin. She felt so much pain it was as if someone had stabbed her millions of times in the heart. What is the point of living if there is nobody who even knows you exist? The Grandfather clock strikes six in the evening. She strolls back to the photo of her with her grandchildren. Dorothy bursts out in tears – her eyes sore and red and waterfalls of tears flowing down her face. She picks up the photo and holds it against her broken heart. Dorothy still hopes to get that special phone call from her much-loved grandchildren.
