Wood technology is the knowledge of the structure, properties, and processing characteristics of wood and the application of this knowledge to industrial processes; including the utilization of wood and the design, production, manufacture, or reconstruction of wood products. The responsibilities of the wood technologist are varied, but generally fall into the broad categories of technical control, production, distribution or research. Technical control may include selection and procurement of raw material, equipment, and supplies, quality control of products, technical supervision of processes, and product development. Production involves supervision of processes, departments or plants and thus requires, in addition to technological knowledge, a grasp of administrative and industrial engineering skills. Distribution may be of materials, supplies, and equipment to the wood-using industry or of the products manufactured. Research, in addition to wood conversion activities, wood technologists also fill research roles to develop the knowledge on which technological advances in the wood industry are based. A wood technology education must provide a basis from which specialization in any of the above areas may develop through either work experience or additional formal education. As with engineering, professional courses in wood technology are built on a strong background in mathematics and physical sciences. Although some knowledge of biology is necessary, most types of wood conversion do not require the depth of understanding of biology that is essential to forestry.
To understand the behavior of wood and its processing, one needs a grasp of mathematics at the level of the calculus and preferably differential equations, engineering-level physics, organic and desirably physical chemistry, and a basic engineering knowledge of force systems and mechanics of materials. Superimposed on this background must be knowledge of wood as a material, including its microscopic and submicroscopic structure and its physical, mechanical, and chemical properties and behavior. The wood technologist needs to know the principal products made from wood, how they are manufactured, and standards pertaining to them from the standpoints of marketing and use. Of particular importance is a thorough understanding of the basic processes through which wood must pass in its conversion to the wide variety of products made from it.
Wood technologies span a broad area of study that covers technological developments in society. Effective wood technology cannot be taught at the descriptive level. To teach the fundamental work in anatomical, physical and mechanical, and chemical properties and behaviour of wood, and the basic processes of machining, drying, gluing, and preservation and protection, special laboratory facilities are essential. For example, to learn the working properties of modern adhesives and their application, the bonding processes and factors that affect them, and the performance of glued wood assemblies, one must measure the properties of adhesives and make and test assemblies glued with them. This requires laboratory-size mixing and spreading equipment, hot and cold presses, instrumentation for measuring chemical and physical properties of adhesives, heat transfer, and pressure applied, and also glue-bond testing equipment and instrumentation. This equipment should be on a small scale and so designed that all factors coming into play in any gluing process in a production plant can be simulated and studied under controlled conditions. Similarly, special laboratory equipment is needed for each of the other areas of study.
In primary schools, teachers plans their wood technologies curriculum in ways that helps children to:, develop knowledge and understanding of the important principles and ideas of the technologies, access and develop skills and understanding in the safe, and hygienic use of an extensive range of tools, resources and materials (e.g. saws, drills), use accurate measurements in millimeters and suitable materials to create a product of a very high standard, find innovative and creative solutions when designing and making products which they test and evaluate, develop a range of skills that enhances their capacity for critical thinking and problem solving within technological contexts, develop informed attitudes towards their immediate environment and help to place their learning within a Scottish and global context and make links across curriculum areas and provide relevant contexts which build on prior learning.
In best practice, as children progress through the school, teachers ensure that contexts extend to the wider environment and include links with industry, businesses and the community. This supports the development of children’s knowledge and skills about advances in wood technologies. It also helps children understand how wood technological developments have responded to society’s needs and how they might be developed further in the future.
Woodworking teaches basic and advanced hand-eye coordination in children while the brain is still developing. Children and teenagers can learn abstract thinking skills that allow for better coordination between visual cues, tactile cues and mental images. Developing good hand-eye coordination can provide an advantage throughout life.
Wood work teaches students how to use a range of basic tools. Some students might never have the opportunity to learn how to use a saw, plane or drill in any other environment. Students might even learn how to operate machinery like a lathe, band saw or belt sander. These tool skills can be very useful later when making repairs to a house or building furniture. The skills could even start a lifelong love of woodworking.
Wood work requires students to think abstractly in three dimensions. This develops spatial visualization in the brain. Spatial visualization allows students to better understand the relationship between objects in space. It is an essential ability for students who want to enter into science, engineering or math careers.

Wood Extension Project

...Wood is one of the most widely used materials in the world. For a wood extension project, I decided to extend my plank of wood physically and conceptually. I decided to create a phone from a plank of wood and turn it into a persuasive poster in order to raise awareness of being present, being mindful of everything that the "now" moment contains. Wood is clearly a natural resource. At the spiritual level, trees help people become more aware of the connections with something larger than themselves. In mythology, trees are sometimes portrayed as the abodes of nature spirits. Trees call people to a state of “mindfulness,” where they become better in tune with and more compassionate toward the surroundings. I came across the idea of extending my...

...she wouldn’t even think about going swimming in the river. It seems like the author misses the house she grew up in when she was little. The story is directed towards older adults and bringing back their childhood memories and how bad it is not to be a child anymore. The reason I could tell who it is directed to is because that’s the only people that could understand what she’s actually feeling. She sadly talks about how the fields were ruined, elm trees she loved fell down, and that the town also built anther highway ruining the scenery. It shows me that enjoy the time as a child you have now because you will never be able to return to it. Another thing that had her chocked up was the private property signs. She loved walking through the woods freely not worrying about getting yelled at or arrested. The essay ends talking about how to try to preserve the wildlife. The essay a walk on the wild side was a very good written piece. I liked the descriptiveness of how southern Ontario use to be and now how it is.

Richard Louv's "Last Child in Th Woods" Essay

...our technology has exceeded our humanity.” Richard Louv, writer of Last Child in the Woods conveys a sarcastic tone and imagery to address the idea of “why do so many people no longer consider the physical world worth watching?” He also ponders, “Why do so many Americans say they want their children to watch less TV, yet continue to expand the opportunities for them to watch it?” Louv visualizes explaining the nineteenth century to a younger generation and how they will not understand what they hear. Louv assumes, “’You did what?’ they’ll ask. ‘Yes,’ we’ll say, ‘it’s true. We actually looked out the car window.’” He is sarcastic because he is in disbelief at how oblivious adolescence is becoming. Louv finds it humorous that children are becoming so dependent on technology and are becoming so detached from nature. He mocks our future generation and their foolhardiness that is arising within them. Richard Louv reminisces his days in the back seat of a driving car, and vividly explains his experience through imagery. He remembers when he “started with a kind of reverence at the horizon, as thunderheads and dancing rain moved with” him. He also personifies the “dancing rain” to portray his full image. Louv understands technology is going to expand and become more broad; however he can understand the intellectual details of nature that he remembers and realizes that technology is distracting people from visualizing “the variety or architecture, here and there; the woods and...

Guajilote Swot

...1. What are the strengths and weaknesses of Guajilote? Guajilote uses three operations using very simple technologies, which means they only need limited capital to maintain the equipment. They have committed and determined members and employees. Santos Munguia has been the leader since 1995 and was able to renegotiate a better price for the sale of the cooperative’s wood. Due to the law of supply and demand, the price for the mahogany will increase when the world supply decreases. They are an environmentally friendly cooperative that only harvests fallen mahogany trees. The lives of the members of Guajilote improved significantly for them and their family members. Although the staff is committed and determined, they have no education or training and Munguia has no educated leadership. They have limited distribution channels and their current distributor may not be paying them enough right now. Also, they don’t have enough capital and even a lack of access to credit to buy their own truck for transportation. They only have one product which means they are completely reliant on that. They have a low technology process. 2. What are the opportunities and threats facing Guajilote? If they are able to buy their own transportation, they can could cut the distributor and double their revenues by hauling their wood to Honduras’ major market centers. They can use specialty shops and catalogs throughout the world that might be interested in selling high quality mahogany furniture...

...the film is trying to convey or what it is about. In Ana’s Playground and The Cabin in the Woods discussions of gender are seen throughout the content and context of the film when it is analysed through its cinematic coding. Ana’s Playground, 2009 is a short film about a group of young children playing a game of soccer on the streets in a war-torn country. When their ball is kicked over a fence, Ana is faced to risk her life in a challenge to retrieve the soccer ball whilst a sniper is shooting at her. Violence is the main thematic value within Ana’s Playground as it is present throughout the whole film.The film gives us an insight of how children live and experience the violence that occurs within war-torn countries. The four children seen within this film is Ana, what appears to be her little sister, and two other boys. When Ana is chosen through the use of coin flipping, to retrieve the ball from over the fence, the audience would expect one of the boys to replace this life risking duty as this is a gender expectation from the audience. This shows that the female gender is represented as being obedient but also very vulnerable. From the very moment Ana is chosen to retrieve the ball, is a representation of her innocence and naivety being lost. The Cabin in the Woods, 2011 is a recent Hollywood comedy horror film about five friends that go on a holiday to a remote cabin in the woods and unknowingly are being observed and become victims for a ritual.

Osmose Wood Preserving, 340 Md. 519 (1994), a number of homeowners purchased townhomes that had a roofs constructed of Fire Retardant Treated (FRT) plywood manufactured by the defendant Hoover Treated Wood Product, Inc. (Hood Wood). Homeowners claim in their complaint the fire retardant treated plywood, when exposed to high temperatures begin an acidic reaction that was designed to stop the spread of fire. It was also alleged that the reaction can occur at temperatures as low as 130 degrees and roofs can reach 180 degrees without the presence of fire. The homeowners say that the chemical reaction “weakens the wood and destroys the bonding between the plywood laminates, thereby causing the wood, among other things, to bow, darken, spot, warp fracture and otherwise deteriorate and lose strength capacity.” The homeowners claim that this reaction will eventually occur in the plywood installed in their homes, without regard to ventilation or moisture levels I attics. Management also advertised there products falsely after begin notified. The homeowners brought this class action suit to recover cost to replace their roofs that had the alleged defective fire retardant treated plywood.
