For birds, flight is the main source of locomotion. For 160 million years, birds have flown. Birds are able to fly due to a variety of special features. They have high metabolisms to supply their body with energy. They have lightweight bones as well. They have feathers, some of which are flight feathers that are long and strong with also help birds fly. They also have a bone called a furcula, in their chest, which is very important for being able to produce the strength and support needed to flap their wings. Birds also have very powerful muscles to power their wings, which means they can flap their wings so fast so that they can take off from the ground and move through the air, as well as gliding through the air. A bird can make its feathers close tightly together which, when gliding or flapping, forces the air to flow around their top and bottom wing surfaces to help them fly. It can also make its feathers open, which allows the air to pass straight through them, which allows the bird to fall. So, because a bird can set its wing feathers to be in any of a vast number of positions ...
The idea of writing at any school level or in life is seen more as a grueling task than enjoyable experience. In the novel, Bird by Bird, the author Anne Lamott is speaking to a generation of writers, who may be struggling with the process. The content is rich with stories to help the writer analyze his or her own life to add it to their writing style, a concept that may be hard for some people. Bird by Bird is an effective book, because Lamott includes not only writing tips, but a sense of humor along with life advice.
In A Bird in the House, Margaret Laurence is able to incorporate many themes and motifs into her stories such as, war, tragedy, religion, and faith. Another theme that is also shown throughout the book is identity, both national and individual identity. National identity is defined as “ a sense of a nation as a cohesive whole, as represented by distinctive traditions, culture, etc.”, while individual identity is what makes a person unique, it is what a person believes, thinks and feels. Sometimes in life identity gets mixed up and can become a confusing aspect of life. People are a product of their environment, which is a factor in shaping identity. The protagonist in the book, Vanessa MacLeod, witnesses and experiences both types of identity. She sees the influence of the Canadian national identity in her Grandfather Connor, Scottish heritage in her Grandmother MacLeod, Irish heritage in her Uncle Dan, which ultimately influence Vanessa’s personal identity.
Paper Airplanes, flight at its simplest for humans. As kids, we learned how to build paper airplanes and send them soaring into the sky. We didn't stop to think about why the airplanes where able to fly after the initial thrust we gave them or how they were able to glide for so long afterwards. Ignorance was bliss then, but now we strive to understand how things work. Looking back to the childhood past time of flying paper airplanes, I will try to explain some of the parts that make paper airplanes fly.
All flight is the result of forces acting upon the wings of an airplane that allow it to counteract gravity. Contrary to popular belief, the Bernoulli principle is not responsible for most of the lift generated by an airplanes wings. Rather, the lift is created by air being deflected off the wings and transferring an upward force to those wings.
One of the most powerful recurring themes in these two Hitchcock's films is the procession of domineering mothers.
Australia is the largest island in the world and is the only country to occupy an entire island. Australia is also the smallest continent. When people think of Australia, they think about kangaroos and the outback (Lepthien 7). However, there is much more to learn about this unique country, including information about its geography, climate, government, people, plants, and animals.
On Thursday 13, 2014, I visited the American Museum of Natural History in Central Park, New York City. When I first entered the museum I saw the dinosaurs that were another revelation. I felt the excitement rushing through my veins. In the museum, I observed and took notes on many exhibits that I enjoyed in my assigned hall and other halls.
Wings create lift for the upward force of an airplane. A great example of how this happens is sticking your hand out of a car window driving down the freeway. The force on your flat palm causes a force that can lift your hand up or down by changing the
I personally do not enjoy writing like most people would feel about reading a dictionary. I am cautiously treading water with every word I type. I have always found writing to be a tedious process. I have never found ease in wording something the way I want to; therefore, it usually sounds so much better in my head. I’ve never considered myself to be comfortable with writing in general. For example, I always had a hard time telling if I needed a comma in a sentence or not. Sometimes it was obvious, but it seems more confusing most of the time.
Most of us are aware that spending time in nature is good for us. Not so many, however, can say exactly why this is the case. Although understanding the exact reasons why the natural world can positively influence your general well-being isn’t going to increase the benefit, it might just inspire you to get out there and spend more time in our planet’s very own, natural quality-of-life-enhancer - nature itself. Below, we’ve listed five of these reasons in hope of doing just that…
When many people hear about the term “landscape”, they immediately think that it means “nature”. The natural landscape does play an important role in our society but what is more important is the landscape that we make and occupy. So, what exactly is “landscape”? The term can be illiterate in many ways but the definition given by the European Landscape Convention is perhaps the most useful and widely agreed one. It states that a landscape is ‘an area, as perceived by people, whose character is the result of the action and interaction of natural and human factors.’ This definition captures both the idea of landscape being physical like a tract of land, but also something that is mind and social shared, something that is perceived by the people. When it comes to Landscape Architecture, the International Federation of Landscape Architects says that ‘Landscape Architect conduct research and advise on planning, design, and stewardship of the outdoor environment and spaces, both within and beyond the built environment, and its
What is animal science? Why does animal science even exist? How many areas of study ar in animal science s? Does the average person relate to animal science at any given point in their life? Animals “ are a part of our sustenance, our sociology, and our day-to-day lives.” Animals play a vital role in our lives that we live and why we study everything about them.
Science is about understanding and building knowledge about how the natural world works. It explains the inter-relationship with one's life and nature and promotes environmental education and more so environmental habits. Science teaches us as learners’ important skills such as reasoning, problem solving, analyzing, predicting, etc. It builds a foundation by providing a base in case a child does not go to higher level of education. Since science is all around us it is important to teach it so that the children could learn about themselves and their environment. Science also provides the knowledge needed to create new pieces of technology, which scientists used to develop civilization. For example, rather than writing
Birds have direct and indirect economic and cultural values for people. Birds are important for a lot of reasons. Birds provide us food, medicine, fertilizers and also bring about pollinations. They are important because they are a part of the food chain. Birds are also important because they help spread seeds around and thus help with the planting process. Birds also perform vital ecological role, besides their economical role. They are critical links within the fast food chains and webs that exist in the ecosystem. The economic importance of birds can be studied into two parts – A) Beneficial effect B) Harmful effect.
NEED AND PURPOSE FOR CONSERVATION OF BIODIVERSITY Biodiversity conservation is about saving life on Earth in all its forms and keeping natural ecosystems functioning and healthy. Biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems, climatic changes, pollution, invasive exotic species, diseases, shifting cultivation, poaching of wildlife etc. Since the human beings are enjoying all the benefits from biodiversity, they should take proper care for the preservation of biodiversity in all its forms and should prevent the degradation as well as the destruction of the habitats, thereby maintaining the biodiversity at its optimum level which will ultimately conserve the biodiversity for the future generation. The United Nations designated 2011-2020 as the United Nations Decade on Biodiversity. In biodiversity, each species, no matter how big or small, has an important role to play in ecosystems.
