A ．阅读下列短文，根据短文内容填写表格，每空只能填写一个词(5分)
Mum and dad are two of the most important people in your life. You probably see at least one of them every day. And they influence(影响) you more than anyone else you meet in your life. So if your mum loves reading, you just grow up carrying a book wherever you go, just like she does.
But parents do a lot more than just passing on their interest. Mums and dads care for their children from the minute they were born. So they are the people you should respect(尊敬) and love best. It's very necessary(必要的) to stay close, get along(相处) and build a strong relationship with your parents. But not every child knows how to do this. Here are some ways to help you.
Spend time together . Don’t play a computer game or watch TV. Ask your mum and dad to play with you. Go outside together, or read a book.
Be kind . Little things might mean a lot to your mum or dad. You can make your parents happy with a hug (拥抱), a card, or a joke. It's also lovely when a child cleans up his or her room without being asked. And if you try not to fight with your brothers or sisters, your parents might be very happy.
Do your best at whatever you do . You don't have to be perfect, but if you do your best, you will make your parents feel proud. It makes them happy to see how you're turning into a great kid. Why? Because it lets them know you're doing a good job.

物理实验总结 第一章：声现象 实验1：探究声音产生的条件（音叉和水、音叉和乒乓球、讲话、击带纸屑的鼓……）易错点： 1.结论：发生的物体在振动（声音由物体振动产生）。 2.实验方法：转化放大法。 实验2：固体、液体、气体能否传声（双音叉和乒乓球、晾衣架用细线悬挂并把线的末端在手指上缠绕后插入耳朵、在水中摇铃……） 易错点： 1.实验方法：转化放大法。 实验3：真空不能传声（玻璃钟罩抽气） 1.现象：手机铃声逐渐减小，最后几乎听不见。 2.实验方法：理想推理法。 3.结论：实验现象表明声音的传播需要介质从而推断真空不能传声。 实验4：声音的响度和振幅的关系、音调和频率的关系（拨钢尺、击鼓、拨木梳、电动机打纸片、吹水杯、敲水杯……） 易错点： 拨钢尺： 1.实验步骤： 将一根钢尺的一端紧压在桌面上，另一端伸出桌边，保持钢尺伸出桌边的长度，先后用大小不同的力拨动钢尺使它振动，比较两次声音响的的大小。再改变钢尺伸出桌边的长度，先后用大小相同的力拨动钢尺使它振动，比较两次声音音调的高低。 2.结论： 同一声源振幅越大，响度越大。频率越快，音调越高。 3.实验方法：控制变量。 实验5：不同琴弦声音的三要素。（材料、松紧、长度、横截面积） 实验6：比较不同材料的隔声性能。 易错点： 1.实验原理：同响度（听不见）比距离。 现象解释：蝴蝶飞听不见等：声源振动频率小于20赫兹，不在人耳可听范围内。 第二章：物态变化 关于物态变化的现象解释：点名物态变化的名称即可。
实验1：影响水蒸发快慢的因素（表面积、空气流速、温度） 易错点： 1.实验方法：控制变量法。 2.结论：水蒸发的快慢与水的表面积有关，水的表面积越大，蒸发速度越快。 水蒸发的快慢与水的温度有关，水的温度越高，蒸发速度越快。 水蒸发的快慢与水的表面空气流速有关，水的表面空气流速越大，蒸发速度越快。 3.典型错误：未控制水的质量变量。 理由：水的质量不一样，未控制变量，无法比较蒸发快慢。 实验2：水沸腾 易错点： 1.从开始加热到沸腾时间过长的原因是：加热的水的质量过大或水的初温太低或未加盖。 2.实验中观察：水的状态和温度计示数的变化。 3.停止加热后降温快慢不同的原因：水的质量不同。 4.最终温度相同的原因：环境温度相同，都为xx度。 5.蒸馏净水的现象：集水的容器中有水出现，冷却物温度升高（或温度计示数升高）。 6.加盖的作用：加快水的沸腾，减少加热时间；防止水蒸气在温度计上液化影响读数。 7.石棉网：使烧杯受热均匀。 8.结论：水沸腾的条件是温度达到沸点且持续吸热。 9.加热后烧瓶倒置，在底部浇冷水或敷冷湿毛巾，水重新沸腾。 10.解释：浇冷水后烧瓶内水蒸气遇冷液化，使瓶内气压减小，水的沸点降低，从而重新沸腾。 实验3：冰、蜡烛的融化、凝固。 易错点： 1.水浴加热的好处：若不水浴则固体受热不均，即使受热，温度计测量的温度也不准确。水浴可是固 体受热均匀。 2.实验中观察：物质的状态和温度计示数的变化。 3.石棉网：使烧杯受热均匀。 实验4：模拟雨的形成 易错点： 1.步骤：在烧瓶中注入适量水，用酒精灯加热，在瓶口上方倾斜地放置一个加了冰块的金属盘。 2.冰块的作用：加快水蒸气的液化。 3.现象：烧瓶口有“白雾”出现，金属盘底部出现小水珠。 4.解释：锥形瓶中的水沸腾其化成水蒸汽，在瓶口遇冷液化成小水滴，形成白雾；在金属盘底部遇冷 液化成小水珠，形成“雨滴”。 实验5：碘的升华和凝华 易错点： 1.现象：碘粒减少，碘锤内充满紫红色碘蒸气；停止加热并滴加水后，紫色碘蒸气逐渐凝华为固体小 颗粒，且上端的颗粒比下端多。 2.加冷水的作用：加快碘的凝华。 实验6：比较水、盐水的凝固点（即熔点） 易错点：

中考物理实验题型归类分析 物理学是一门以观察、实验为基础的科学．人们的许多物理知识是通过观察和实验认真地加以总结和思索得来的．因此，中考物理试题中实验题就成了热点问题，分数比例较大，而有相当一部分考生忽视物理实验的复习，或不知道怎样复习，不知道中考哪几个方面考核，失分较多，影响了考试成绩．为了帮助同学们有目的搞好实验复习，仅就部分省、市中考实验题归纳为以下几个类型，供复习时参考． 一、数据处理型 例1．测定牛奶的密度 (1)某同学做“测定牛奶密度的实验”． ①用调好的托盘天平测量盛有牛奶的玻璃杯的质量，测得它们的总质量为138.0克； ②把玻璃杯中的一部分牛奶倒进量筒里，量筒 中牛奶的体积如图1(1)所示； ③把玻璃杯和杯中剩下的牛奶放在托盘天平 上称量，当天平恢复平衡时，托盘上三个砝码的质量，游码的位置如图1(2)所示． 把步骤①、②、③中测得数据填入下表中求出牛奶的密度． 二、仪器使用型 2．图2中，甲图是伏安法测未知电阻R x 的电路图，乙图是电流表、电压表的实物示意图．电源是两节干电池，待测电阻估计约为10欧姆，请回答下面问题： (1)开始实验时，滑动变阻器的滑动片应置于滑动变阻器的_____端． (2)电压表应选用“+”接线柱和表示量程为______伏特的负接线柱；电流表应选用“+”接线柱和表示量程为______安培的负接线柱． 三、找错型 3．某同学做用伏安法测电阻的实验时，用了两节干电池,带测电阻阻值约为10欧，连结了图3所示的实物电路，简要写出图3中的三处错误 (1)_________________________； (2)_________________________； (3)_________________________．
教学课例 ——数字实验室在《摩擦力》教学中的应用 教学课题滑动摩擦力和正压力 教学内容探究滑动摩擦力的大小跟哪些因素有关，用什么办法可以测定它们的大小 教学重点、难点探究滑动摩擦力大小跟物体表面受到的压力以及接触面的粗糙程度的关系 实验器材数据采集器、力传感器、计算机、长木板、细绳、摩擦力实验器、毛玻璃、包装纸、铁架台等 数字化实验设备简介（如图1） 1．传感器：数字化实验的核心部件。“感”将物理量转化成电信号；“传”将电信号传递到数据采集器装置和计算机平台。教学中常用的传感器包括力传感器、位移传感器、热传感器、电流电压传感器、光传感器、声传感器等等，图中是一个位移传感器。 2．数据采集器：采集传感器感知的数据，并传给计算机，可以说是传感器与计算机连接的转换器。 3．实验仪器：完成某一物理实验需要的仪器，如小车、导轨、灯泡、电源、开关、线圈、磁铁等。 4．计算机及其内部处理由传感器传递的数据的软件。
5．实验结果：实验中采集的数据用计算机进行分析处理，通过计算机显示器直接显示以数学方式展现的图表和图象，物理现象和规律通过数学的图象和图表呈现。 由此可知，数字化实验是将传感器、计算机与传统的实验仪器结合，是传统实验方法的发展和数据处理的科学化，呈现的是真实的实验，数据处理上更严谨，规范。 对传统实验的改进方案及结果分析： 《摩擦力》是初中物理最重要的概念之一，新课程标准对本节的要求之一是通过实验认识滑动摩擦、静摩擦的现象，探究滑动摩擦力跟哪些因素有关系；实验原理是让木块匀速运动，应用二力平衡的知识用拉力来反映摩擦力。 传统教学中采用图2的装置，用弹簧秤水平拉一个放在水平长木板上的木块，学生通过观察木块从不动到运动的过程中弹簧秤示数的变化，来认识摩擦力。但由于仪器较粗糙，数据的变化不易看得很清楚，本实验大多情况下作为了一种模糊的定性研究。 用传感器参与本实验，实验原理不变。但图2中的弹簧秤换为力传感器效果也不好。于是我们想到用图3的装置，将力传感器固定，感知力的一端通过一段弹性不大的细绳与木块连接做本实验，这样木块始终与地保持相对静止。拉动木板，在刚加拉力时木块与木板有相对运动趋势，木块与木板间有静摩擦力，木板运动起来，木块与木板有滑动摩擦力，由于木块始终相对静止，因此各个时刻的拉力就反映了对应的摩擦力。实验数据传入计算机，木块抽动过程中拉力的变化以图4中的红线形式展示。这样木块由不动到运动中摩擦力的变化就通过拉力变化的图线清楚的呈现给学生。

苏教版初中物理知识点大全 第一章．声现象知识 1 . 声音的发生：由物体的振动而产生。振动停止，发声也停止。 2．声音的传播：声音靠介质传播。真空不能传声。通常我们听到的声音是靠空气传来的。 3．声速：在空气中传播速度是：340 米/秒。声音在固体传播比液体快，而在液体传播又比空气体快。 4．利用回声可测距离：S=vt/2 5．乐音的三个特征：音调、响度、音色。(1)音调:是指声音的高低，它和发声体的频率有关系。(2)响度:是指声音的大小，跟发声体的振幅、声源和听者的距离有关系。 6．减弱噪声的途径：(1)在声源处减弱；(2)在传播过程中减弱；(3)在人耳处减弱。 7．可听声：频率在20Hz～20000Hz 之间的声波：超声波：频率高于20000Hz 的声波；次声波：频率低于20Hz 的声波。 8．超声波特点：方向性好、穿透能力强、声能较集中。具体使用有：声呐、B 超、超声波速度测定器、超声波清洗器、超声波焊接器等。 9．次声波的特点：可以传播很远，很容易绕过障碍物，而且无孔不入。一定强度的次声波对人体会造成危害，甚至毁坏机械建筑等。它主要产生于自然界中的火山爆发、海啸地震等，另外人类制造的火箭发射、飞机飞行、火车汽车的奔驰、核爆炸等也能产生次声波。 第二章物态变化知识归纳 1. 温度：是指物体的冷热程度。测量的工具是温度计, 温度计是根据液体的热胀冷缩的原理制成的。 2. 摄氏温度(℃):单位是摄氏度。1 摄氏度的规定：把冰水混合物温度规定为0 度，把一标准大气压下沸水的温度规定为100 度，0 度和100 度之间分成100 等分，在每一等分为1℃。 3．常见的温度计有(1)实验室用温度计；(2)体温计；(3)寒暑表。体温计：测量范围是35℃至42℃，每一小格是0.1℃。 4. 温度计使用：(1)使用前应观察它的量程和最小刻度值；(2)使用时温度计玻璃泡要全部浸入被测液体中，不要碰到容器底或容器壁；(3)待温度计示数稳定后再读数；(4)读数时玻璃泡要继续留在被测液体中，视线和温度计中液柱的上表面相平。 5. 固体、液体、气体是物质存在的三种状态。 6. 熔化：物质从固态变成液态的过程叫熔化。要吸热。 7. 凝固：物质从液态变成固态的过程叫凝固。要放热. 8. 熔点和凝固点：晶体熔化时保持不变的温度叫熔点；。晶体凝固时保持不变的温度叫凝固点。晶体的熔点和凝固点相同。 9. 晶体和非晶体的重要区别：晶体都有一定的熔化温度（即熔点），而非晶体没有熔点。10. 熔化和凝固曲线图： 11.（晶体熔化和凝固曲线图）(非晶体熔化曲线图） 12. 上图中AD 是晶体熔化曲线图，晶体在AB 段处于固态，在BC 段是熔化过程，吸热，但温度不变，处于固液共存状态，CD 段处于液态；而DG 是

初中物理《力与运动》知识点总结 一、牛顿第一定律 1.牛顿第一定律 (1)内容：一切物体在没有受到外力作用时，总保持匀速直线运动状态或静止状态。这就是牛顿第一定律。 (2)牛顿第一定律不可能简单从实验中得出，它是通过实验为基础、通过分析和科学推理得到的。 (3)力是改变物体运动状态的原因，而不是维持运动的原因。 (4)探究牛顿第一定律中，每次都要让小车从斜面上同一高度滑下，其目的是使小车滑至水平面上的初速度相等。 (5)牛顿第一定律的意义：①揭示运动和力的关系。②证实了力的作用效果：力是改变物体运动状态的原因。③认识到惯性也是物体的一种特性。 2.惯性 (1)惯性：一切物体保持原有运动状态不变的性质叫做惯性。 (2)对“惯性”的理解需注意的地方： ①“一切物体”包括受力或不受力、运动或静止的所有固体、液体气体。 ②惯性是物体本身所固有的一种属性，不是一种力，所以说“物体受到惯性”或“物体受到惯性力”等，都是错误的。 ③要把“牛顿第一定律”和物体的“惯性”区别开来，前者揭示了物体不受外力时遵循的运动规律，后者表明的是物体的属性。 ④惯性有有利的一面，也有有害的一面，我们有时要利用惯性，有时要防止惯性带来的危害，但并不是“产生”惯性或“消灭”惯性。 ⑤同一个物体不论是静止还是运动、运动快还是运动慢，不论受力还是不受力，都具有惯性，而且惯性大小是不变的。惯性只与物体的质量有关，质量大的物体惯性大，而与物体的运动状态无关。 (3)在解释一些常见的惯性现象时，可以按以下来分析作答： ①确定研究对象。 ②弄清研究对象原来处于什么样的运动状态。 ③发生了什么样的情况变化。
