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1太阳对地球的影响教案
当时，不只发生了太阳风暴，同时还有其它的现象发生，导致灾难巨大。 如果，这些现象单独地发生，结果就会是另外一个样子。正是由于这些因素综合起来，1859年的太阳风暴，才在人类历史上留下了浓墨重彩的一笔。太阳磁暴开始干扰通信日本卫星首个被“击中”日本航天机构29日声明，受强烈的太阳磁暴影响，28日晚，日本“儿玉(Kodama)”通讯卫星信号中断。 据美联社报道，在太阳黑子活动减弱后，“儿玉”通讯卫星恢复正常运转。 美欧研究人员28日发布新闻公告称，太阳当天发生了一次强烈的耀斑爆发，预示着新一轮太阳风暴将在今后一两天内抵达地球，地球上的通信等设施可能会因此受到部分干扰。与这次耀斑爆发相伴，太阳表面还产生了一股强大的日冕物质喷射，方向几乎直冲地球。研究人员说，喷射产生的带电粒子流正以约每小时750万公里的速度奔地球而来，其与地球磁场作用后可能会形成比较强烈的地磁暴，使地球两极出现极光，并可能对卫星运行和通信等造成干扰。
人教版新课标高中物理必修1弹力教案2篇
一般情况下，凡是支持物对物体的支持力，都是支持物因发生形变而对物体产生弹力。所以支持力的方向总是垂直于支持面而指向被支持的物体。例1：放在水平桌面上的书书由于重力的作用而压迫桌面，使书和桌面同时发生微小形变，要恢复原状，对桌面产生垂直于桌面向下的弹力f1，这就是书对桌面的压力；桌面由于发生微小的形变，对书产生垂直于书面向上的弹力f2，这就是桌面对书的支持力。学生分析：静止地放在倾斜木板上的书，书对木板的压力和木板对书的支持力。并画出力的示意图。结论：压力、支持力都是弹力。压力的方向总是垂直于支持面而指向被压的物体，支持力的方向总是垂直于支持面而指向被支持的物体。引导学生分析静止时，悬绳对重物的拉力及方向。引导得出：悬挂物由于重力的作用而拉紧悬绳，使重物、悬绳同时发生微小的形变。重物由于发生微小的形变，对悬绳产生竖直向下的弹力f1，这是物对绳的拉力；悬绳由于发生微小形变，对物产生竖直向上的弹力f2，这就是绳对物体的拉力。
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？

人教版高中历史必修2古代手工业的进步教案
①原因：封建制度的衰落（根本原因）【合作探究】清朝资本主义萌芽缓慢发展的原因。提示：①封建所有制的束缚。残酷的封建剥削使农民赤贫如洗，无力购买手工业品，限制了手工业产品的销路。封建地租的剥削率很高，又驱使地主和商人把他们的钱财用于购买土地，影响资本主义手工业的扩大再生产。②.封建政府的压制。清政府实行重农抑商的政策，采取了许多妨碍手工业生产和资本主义萌芽发展的措施，主要的有：实行闭关政策，严格限制海外贸易；在国内广设关卡，对商品征收重税；严格控制手工业的生产规模，如建立受官府控制的行会，制定行规限制雇工人数、产品品种、控制原料分配，限制产品销售的价格和地区范围等。②发展的表现：具有资本主义萌芽的部门和地区增多。（参见教材P10“学思之窗”）
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。
