In short, through solid a nd effective w ork initiatives 撬棍这样的简单机械称为“杠杆”。 2、示范用杠杆撬讲台。 3、板书分析杠杆的各个部分名称和定义。 阻力点 用力点 支点 杠杆上有三个重要的位置:支撑着杠杆,使杠杆能围绕着转 动的位置叫支点;在杠杆上用力的位置叫用力点;杠杆克服阻力的位 置叫阻力点。 4、出示 P4 的两张图片:压水井、跷跷板。 请大家在上面画一画,他们的三个点分别在什么位置 5、在展台底下进行反馈交流。 6、分辨杠杆 观察 P4 P5 的这些工具,说说哪些是杠杆,哪些不是杠杆?并说 明理由(找一找三点) 学生自己体验杠杆尺的组成及变化。 三、研究杠杆的秘密 1、 刚才我们用杠杆轻松地撬起了讲台,那是不是所有的杠杆 都是省力的呢? (学生一般认为都是省力的,教师在课堂上举例费力的事件) 让我们用杠杆尺这个工具,来帮助我们更好地进行研究。 2、 对杠杆尺的构造进行介绍和使用方法 学院将成立毕业论文答辩资格审查小组,根据规范要求负责组织本院毕业学生的论文答辩资格审查工作,主要从毕业论文的质量水平、排版格式规范化等方面对论文答辩资格进行审查。毕业论文答辩资格审查应在毕业答辩前完成,审查合格者方能参加毕业答辩。凡论文质量、排版格式等审查未通过者,将责令其返工,直到达到要求为止,否则不准参加毕业答辩。broken probl em, fill the short Board, so that t he majority of party members and fully qualified, com prehe nsive skil ls of grass -roots party organizations, grass-r oots party level upgrade.

In short, through solid a nd effective w ork initiatives 3、 教师问题的提出:如果我在杠杆尺的左边第四格挂上一个 钩码,要使杠杆尺保持平衡,我应该在杠杆尺的右边什么位置挂上几 个钩码 ?(请同学上台来试一试,并说说你是怎么想的) 4、 还有其他方法吗 ? 5、 老师刚才是在左边第四格挂了一个钩码,还可以怎么挂? 那么右边又应该在什么位置挂几个钩码才能使杠杆尺平衡呢?请大 家在小组内合作开展实验,并且把数据记录在 P6 上的表格内。完成 实验之后再把实验数据进行统计:省力情况有( )种,费力情况有 ( )种;不省力也不费力情况有( )种。 6、 对所有的数据进行观察和分析。 1) 在什么情况下,杠杆省力? 2) 在什么情况下,杠杆费力? 3) 在什么情况下杠杆不省力也不费力? 7、 教师进行总结:省力、费力、不省力不费力各情况的比较 和分析。 四、收集数据步骤的反思 我们是按怎样的方法步骤收集数据的?哪种方法更合理? 五、全课小结 【教学目标】 第三课 杠杆类工具的研究 学院将成立毕业论文答辩资格审查小组,根据规范要求负责组织本院毕业学生的论文答辩资格审查工作,主要从毕业论文的质量水平、排版格式规范化等方面对论文答辩资格进行审查。毕业论文答辩资格审查应在毕业答辩前完成,审查合格者方能参加毕业答辩。凡论文质量、排版格式等审查未通过者,将责令其返工,直到达到要求为止,否则不准参加毕业答辩。broken probl em, fill the short Board, so that t he majority of party members and fully qualified, com prehe nsive skil ls of grass -roots party organizations, grass-r oots party level upgrade.
