The central question of this course: “why study wood?” If “why study wood” is the question, one answer would be that it is the only raw material available to us that is truly renewable in human life span terms. Wood is as important to society today as it ever was, despite the development of many man-made substitute materials, changing resource availability, and the changing needs of society. Some items on the list of wood products stay the same (lumber, plywood and veneer for building construction, furniture, shipping pallets & crates and other containers & packaging materials, railroad ties, utility poles, chemical feed stocks, etc), but the list also keeps changing to meet new needs and challenges as the resource changes. In short, wood is a far more diverse, green, and renewable resource than you might have imagined. Join us to learn about the important role of wood in human history, civilization, and our future. By the end of the course, learners will be able to: - describe wood as a raw material and its critical importance to the world economy, and the lives of the people that make that economy work. - identify the projected trend for wood consumption to continue to grow in the coming years, despite the image of wood as a "low tech" material. - identify the ways in which wood's properties can lead to its efficient and sustainable use. -identify wood's positive role in boosting the world economy and ability to lead to unexpected vocations.

木材科学:建筑之外:本课程的核心问题:“为什么要学习木材?”如果是“为什么要学习木材”的问题,那么一个答案就是,它是我们所拥有的唯一可真正在人类生命中再生的原材料跨度术语。尽管已经开发了许多人造替代材料,不断变化的资源可得性以及不断变化的社会需求,但木材对当今的社会仍然比以往任何时候都重要。木材产品清单上的某些项目保持不变(用于建筑结构的木材,胶合板和单板,家具,运输托盘和板条箱以及其他容器和包装材料,铁路扎带,电线杆,化学原料等),但随着资源的变化,清单也不断变化以满足新的需求和挑战。 简而言之,木材是一种比您想象中更加多样化,绿色和可再生的资源。加入我们,了解木材在人类历史,文明和我们的未来中的重要作用。 在课程结束时,学习者将能够: -描述木材作为原材料及其对世界经济的至关重要性,以及使该经济运转的人们的生活。 -确定木材消费量在未来几年中将继续增长的预期趋势,尽管木材是“低技术含量”材料的形象。 -确定木材特性可导致其有效和可持续利用的方式。 -确定木材在促进世界经济中的积极作用以及导致意外职业的能力。
