  • 人教版高中地理必修1全球气候变化教案

    科学家预测,就地区而言,位于低纬度的大部分国家,农作物的产量将减少;而位于高纬度的国家,农作物产量有可能增加。由于不少发展中国家位于低纬度地区,因此,气候变化的这种区域差异性,可能会使发展中国家所面临的问题更为严峻。板书:3全球变暖将加剧水资源的不稳定性与供需矛盾。介绍:全球变暖会影响整个水循环过程,可能使蒸发加大,改变区域降水量和降水分布格局,增加降水极端异常事件的发生,导致洪涝、干旱灾害的频次和强度增加,以及地表径流发生变化。随着径流减少,蒸发增强,全球变暖将加剧水资源的不稳定性与供需矛盾。转折:既然全球变暖会引起很多不利影响,那么作为人类应如何面对这一挑战呢?这就是我们要讨论的第三个问题。板书:三、气候变化的适应对策讨论:请大家阅读结合教材P53气候变化的适应对策部分讨论人类应如何面对全球变暖这一问题 呢?

  • 人教版高中地理必修1山岳的形成教案

    【转折过渡】除了以上所说的褶皱山和断层山之 外,是否还有其他类型的山脉呢?试举一例说明。【学生思考后回答】有,如富士山属于火山。【教师总结】同学们回答的很好,还有火山,那么火山是如何形成的呢?这就是我们要研究的下一个问题。【板书】3、火山【指导读书】请同学们阅读教材P81思考:①玄武岩高原和火山有什么联系与区别? ②火山由哪几部分构成的?③火山的规模是否相同?【学生回答】①联系:玄武岩高原和火山都是由于处于地下深处的岩浆,在巨大的压力作用下,有时候会沿着地壳的薄弱地带喷出地表而形成的。区别:玄武岩高原是岩浆沿着地壳的线状裂隙流出,往往比较宽广。如哥伦比亚高原。火山是岩浆沿着地壳的中央喷出口或管道喷出。如我国长白山的主峰。②火山由火山口和火山锥两部分组成。③火山的规模大小不一,大火山的相对高度可达4 000~5 000米,火山口直径为数百米;小火山的相对高度不及100米。

  • 人教版高中地理必修2工业地域类型教案

    1.生产上的联系:有投入——产出的关系工业生产的过程复杂,工序繁多,往往需要经过多家工厂的加工才能完成一种产品的生产过程。因此,在这些工厂之间就存在着产品与原料的联系。一家工厂生产的产品是另一家工厂的原料,这两家工厂之间就形成了工序上的工业联系。2.非生产上的联系:如地理空间上的联系布局在同一个工业区内,共同利用工业区的道路、供水、供电、通信等基础设施以及其他生产、生活服务设施,或者共同利用当地廉价的劳动力,形成了空间利用上的工业联系。我国许多地方的经济技术开发区就是建立在这种工业联系基础上的。(二)工业集聚1.形成具有工业联系的一些工厂往往近距离地聚集起来,形成工业集聚现象。2.工业集聚可获得效应(1)工业集聚可以加强企业间的信息交流和技术协作,降低中间产品的运输费用和能源消耗,进而降低生产成本,提高生产效率和利润,取得规模效益。

  • 人教版新课标高中物理必修1力的分解教案2篇

    一、教材内容经全国中小学教材审定委员会2004年初审查通过,人教育出版社出版的普通高中课程标准实验教科书《物理必修①》,第三章第5节内容“力的分解”。二、教学目标1.知识与技能(1)理解分力的概念,理解力的分解是力的合成的逆运算,遵循平行四边形定则。(2)初步掌握一般情况下力的分解要根据实际需要来确定分力的方向。(3)会用作图法和直角三角形的知识求分力。(4)能区别矢量和标量,知道三角形定则,了解三角形定则与平行四边形定则的实质是一样的。2.过程与方法(1)进一步领会“等效替代”的思想方法。(2)通过探究尝试发现问题、探索问题、解决问题能力。(3)掌握应用数学知识解决物理问题的能力。3.情感态度与价值观(1)通过猜测与探究享受成功的快乐。(2)感受物理就在身边,有将物理知识应用于生活和生产实验的意识。三、教学重点、难点在具体问题中如何根据力的实际作用效果和平行四边形定则进行力的分解。

  • 人教版新课标高中物理必修1摩擦力教案2篇

    l.知识与技能:(1)知道摩擦力产生的条件。(2)能在简单问题中,根据物体的运动状态,判断静摩擦力的有无、大小和方向;知道存在着最大静摩擦力。(3)掌握动磨擦因数,会在具体问题中计算滑动磨擦力,掌握判定摩擦力方向的方法。(4)知道影响到摩擦因数的因素。2.过程与方法:通过观察演示实验,概括出摩擦力产生的条件及摩擦力的特点,培养学生的观察、概括能力。通过静摩擦力与滑动摩擦力的区别对比,培养学生分析综合能力。3.情感态度价值观:在分析物体所受摩擦力时,突出主要矛盾,忽略次要因素及无关因素,总结出摩擦力产生的条件和规律。二、重点、难点分析1.本节课的内容分滑动摩擦力和静摩擦力两部分。重点是摩擦力产生的条件、特性和规律,通过演示实验得出关系f=μN。2.难点是学生有初中的知识,往往误认为压力N的大小总是跟滑动物体所受的重力相等,因此必须指出只有当两物体的接触面垂直,物体在水平拉力作用下,沿水平面滑动时,压力N的大小才跟物体所受的重力相等。

  • 人教版新课标高中物理必修2功率教案2篇

    1.用CAI课件模拟汽车的启动过程。师生共同讨论:①如果作用在物体上的力为恒力,且物体以匀速运动,则力对物体做功的功率保持不变。此情况下,任意一段时间内的平均功率与任一瞬时的瞬时功率都是相同的。②很多动力机器通常有一个额定功率,且通常使其在额定功率状态工作(如汽车),根据P=FV可知:当路面阻力较小时,牵引力也小,速度大,即汽车可以跑得快些;当路面阻力较大,或爬坡时,需要比较大的牵引力,速度必须小。这就是爬坡时汽车换低速挡的道理。③如果动力机器在实际功率小于额定功率的条件下工作,例如汽车刚刚起动后的一段时间内,速度逐渐增大过程中,牵引力仍可增大,即F和v可以同时增大,但是这一情况应以二者乘积等于额定功率为限度,即当实际功率大于额定功率以后,这种情况不可能实现。

  • 人教版新课标高中物理必修2平抛运动教案2篇

    (五)平抛运动规律的应用例1:一架老式飞机在高出海面45m的高处,以80m/s的速度水平飞行,为了使飞机上投下的炸弹落在停在海面上的敌船,应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。分析:对于这道题我们可以从以下几个方面来考虑:(1)从水平飞行的飞机上投下的炸弹,做什么运动?为什么?(2)炸弹的这种运动可分解为哪两个什么样的分运动?3)要想使炸弹投到指定的目标处,你认为炸弹落地前在水平方向通过的距离与投弹时飞机离目标的水平距离之间有什么关系?拓展:1、式飞机在高出海面45m的高处,以80m/s的速度水平飞行,尾追一艘以15m/s逃逸的敌船,为了使飞机上投下的炸弹正好击中敌船,应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。2、在一次摩托车跨越壕沟的表演中,摩托车从壕沟的一侧以速度v=40m/s沿水平方向向另一侧,壕沟两侧的高度及宽度如图所示,摩托车可看做质点,不计空气阻力。(1)判断摩托车能否跨越壕沟?请计算说明(2)若能跨过,求落地速度?

  • 人教版高中语文必修1《论语》教案2篇

    【教学意图】要了解中国传统文化,必须阅读古诗文名著名篇。但在中国文化形成过程中影响最大的是什么?可以说是儒家学说,包括《论语》这部经典。《论语》等书是读书人求仕做官的必修课本,是知识分子的思想言行基础,而且影响到整个社会生活,内容包括伦理道德、教育体制、民间习俗等方面的思想。因此,要了解中国传统文化,有必要读一读《论语》。【教学设计】因《论语》的年代已久远,对学生而言,要理解透彻文句是比较深奥困难的,因此必须在充分理解文意的基础上,对《论语》进行思想上的解读。可由教师从《论语》中概括出几点与生活、现实相关的要点,要求学生分组进行透彻的学习和领会,如“小人与君子”、“学习的方法”、“教育的理念”等等。〖教学重点、难点〗读《论语》知儒家思想。〖教学方法〗讲解启发、探究梳理、拓展延伸。

  • 人教版高中历史必修2大众传媒的变迁教案

    【课后研讨】当互联网正大踏步走进人类生活的时候,人们对网络作用的认识似乎还是模糊不清。一种意见认为,作为中学生,他们上网的机会很多,互联网向他们展示了各类知识结构,网络为他们提供了大量信息,又给他们提供了一个接触社会的个性化和国际化的空间,给了他们一个展示自身能力的大舞台,所以他们对于知识选择的灵活性大大增加,学习的主动性也大大提高,学习的内容自然大大超出了狭隘的课本范围,这对于学生能力的提高应是大有裨益的。另一种意见认为,网络的出现无疑为推进素质教育提供了一块绿洲.但部分中学生上网更多的是为了消遣和娱乐,因为网络--这个完全虚拟的世界是他们放松自己的最佳场所。同时也许正基于这一点,家长和师长才会对中学生上网出现不同程度的抵制,因为他们认为网上娱乐分散了他们过多的精力,会对学业造成影响;更为重要的是,他们害怕网络上的不良信息对他们的身心不利。

  • 新人教版高中英语必修2Unit 1 Cultural Heritage-Discovering Useful Structure教案一

    This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2. Instruct students to write essays using the proper relative pronouns and adverbs of attributive clauses.本节语法思考:定语从句在复合句中的作用是什么? 关系词有哪些?定语从句在复合句中的作用相当于形容词,它在句中作定语修饰名词或代词。他们在先行词和定语从句之间起到联系作用,同时在意义上代表先行词并在定语从句中担任一个成分。被定语从句所修饰的词称先行词,定语从句一般放在先行词的后面。
