3、次声波可以传的很远,容易 。一定强度的次声波对人体会造成伤害。

声音的产生

1、声音是由物体的振动产生的;(人靠声带振动发声、蜜蜂靠翅膀下的小黑点振动发声,风声是空气振动发声,管制乐器考里面的空气柱振动发声,弦乐器靠弦振动发声,鼓靠鼓面振动发声,钟考钟振动发声,等等);

2、振动停止,发生停止;但声音并没立即消失(因为原来发出的声音仍在继续传播);

3、发声体可以是固体、液体和气体;

4、声音的振动可记录下来,并且可重新还原(唱片的制作、播放);

声音的传播

1、声音的传播需要介质;固体、液体和气体都可以传播声音;声音在固体中传播时损耗最少(在固体中传的最远,铁轨传声),一般情况下,声音在固体中传得最快,气体中最慢(软木除外);

2、真空不能传声,月球上(太空中)的宇航员只能通过无线电话交谈;

3、声音以波(声波)的形式传播;

注:由声音物体一定振动,有振动不一定能听见声音;

4、声速:物体在每秒内传播的距离叫声速,单位是m/s;声速的计算公式是v=s/t;声音在空气中的速度为340m/s;

怎样听见声音

1、人耳的构成:人耳主要由外耳道、鼓膜、听小骨、耳蜗及听觉神经组成;

2、声音传到耳道中,引起鼓膜振动,再经听小骨、听觉神经传给大脑,形成听觉;

3、在声音传给大脑的过程中任何部位发生障碍,人都会失去听觉(鼓膜、听小骨处出现障碍是传导性耳聋;听觉神经处出障碍是神经性耳聋);

4、骨传导:不借助鼓膜、靠头骨、颌骨传给听觉神经,再传给大脑形成听觉(贝多芬耳聋后听音乐,我们说话时自己听见的自己的声音);骨传导的性能比空气传声的性能好;

5、双耳效应:生源到两只耳朵的距离一般不同,因而声音传到两只耳朵的时刻、强弱及步调亦不同,可由此判断声源方位的现象(听见立体声);

声音的特性包括:音调、响度、音色;

1、音调:声音的高低叫音调,频率越高,音调越高(频率:物体在每秒内振动的次数,表示物体振动的快慢,单位是赫兹,振动物体越大音调越低;)

2、响度:声音的强弱叫响度;物体振幅越大,响度]越强;听者距发声者越远响度越弱;

3、音色:不同的物体的音调、响度尽管都可能相同,但音色却一定不同;(辨别是什么物体法的声靠音色)

注意:音调、响度、音色三者互不影响,彼此独立;

超声波和次声波

1、人耳感受到声音的频率有一个范围:20Hz~20000Hz,高于20000Hz叫超声波;低于20Hz叫次声波;

2、动物的听觉范围和人不同,大象靠次声波交流,地震、火山爆发、台风、海啸都要产生次声波;

噪声的危害和控制

1、噪声:

(1)从物理角度上讲物体做无规则振动时发出的声音叫噪声;

(2)从环保的角度上讲,凡是妨碍人们正常学习、工作、休息的声音以及对人们要听的声音产生干扰的声音都是噪声;

2、乐音:从物理角度上讲,物体做有规则振动发出的声音;

3、常见招生来源:飞机的轰鸣声、汽车的鸣笛声、鞭炮声、金属之间的摩擦声;

4、噪声的等级:表示声音强弱的单位是分贝。符号dB,超过90dB会损害健康;0dB指人耳刚好能听见的声音;

5、控制噪声:

(1)在生源处较弱(安消声器);

(2)在传播过程中(植树。隔音墙)(3)在人耳处减弱(戴耳塞)

声音的利用

1、超声波的能量大、频率高用来打结石、清洗钟表等精密仪器;超声波基本沿直线传播用来回声定位(蝙蝠辨向)制作(声纳系统)

2、传递信息(医生查病时的"闻",打B超,敲铁轨听声音等等)

3、声音可以传递能量(飞机场帮边的玻璃被震碎,雪山中不能高声说话,一音叉振动,未接触的音叉振动发生)

力复习课件 篇4

1.复习所有的声母,先认读卡片上的声母,再背一背。

2.创设情境导入:小朋友们表现得真棒!为了奖励大家,陈老师决定带大家去一个好玩的地方,(课件出示动物园门口的图片)看! 我们来到了什么地方?

1.导入:是谁在欢迎我们的到来啊?(出示连线图)猜一猜(海豚)。

2.你怎么知道是海豚的啊?学生各抒己见。

3.是的,只要我们把所有的声母按顺序连起来,海豚就出现了。

学生动手操作,教师巡查,发现问题及时纠正。

1.导入:你看! 海豚正跳着欢快的舞蹈欢迎我们呢! (出示海豚摆出的类似声母的图片)我们一起来认一认。

2.小组合作:

(1)导入:海豚用身体摆出声母的形状,你还能用其他的东西摆出声母的形状吗?

(2)小组合作:先商量分工,谁是组长、汇报员、记录员,再开始合作。

1.导入:海豚有海中智多星之称,许多科学家们认为海豚是地球上最聪明的动物之一,你想与这么聪明可爱的海豚交朋友吗?

2.示范:海豚姐姐,你好,欢迎你到我们班来,我想和你交朋友。我是陈老师,我姓陈。我的姓里的声母ch和你身上的ch是一样的,很高兴认识你。

3.小组合作:以小组的形式找自己姓里的声母。轮流说,空下的同学当裁判,说对的.奖一颗小红星。教师巡查。

这节课我们大家一起见到了海豚,通过大家的介绍,海豚对我们有了一定的了解,接下来它会带我们去哪里,去干什么呢?我们下节课再继续。

1.导入:这节课海豚姐姐继续带大家去认识更多的动物。(出示图片)咦?这些动物怎么都背对着我们呀! 噢,原来小动物们要我们先读对了每种动物上面的拼音,它才肯回头见我们呢!

(1)zūzhū,cèchè,suōshuō,要分清楚平翘舌音。

(2)nàlà,要读清楚鼻音。

(3)píqí,bǔdǔ看清形近的字母。

1.导入:同学们真能干,全读对了。这些小动物都抢着想把自己介绍给大家,和大家交朋友呢! 你们想先听谁介绍啊?

2.学生自由选择,认读音节词(点击出现,音节由学生读出)。

我是爱开qì chē的小熊,大家好!

大家好,我是爱吃luó bo的兔子!

我是只能干的猩猩,我洗wà zi!

3.小组检查读,教师巡查。

1.过得真快,我们就要离开动物园、告别所有的动物了,临走前动物园的工作人员为我们这些文明的游客送来了纪念品──一张纪念卡,说有能力的人才能得到它。

整堂课的设计以海豚姐姐为主线展开。在完成教材内容的基础上,认识了许多动物,做到了创造性地使用教材。本课的设计,要求老师作为学生学习的引导者、激励者,主动地融入到学生的游戏中去,创造出愉悦、民主的课堂气氛,使学生能大胆地进行交流,提高课堂效率。

学习方式的转变是本次课改的显著特征,在本课的教学设计中,我大胆地对以往的复习课进行改革、创新,转变学习方法:变单纯地说自己姓里的声母为与海豚姐姐的交流;充分运用小姐合作的优势,集合组内成员的力量,用绳子、小棒、肢体等摆出声母,并乘机让学生学会分工合作,使合作的效率得到大大提高。

在每一环节的教学设计中,把学习的主动权还给学生,给他们以足够的时间与空间,让他们充分发挥自己的聪明才智,使课堂焕发出应有的活力。

力复习课件 篇8

教学目标概览

(一)知识目标

通过复习使学生获得的知识系统化,并巩固本章知识。

(二)能力目标

1、提高学生分析、判断和综合运用知识的能力。

2、提高学生解题举一反三的能力。

(三)情感目标

教会学生多角度、度方位看待事物、分析问题,从而了解事物的本质。

教学重点:氧化还原反应、离子反应。

教学难点:氧化还原反应的基本规律和离子反应方程式的书写。

教学方法:启发讨论式

教学过程:

请说出以下四个反应的反应类型

①NH4HCO3 === NH3↑+CO2↑+H2O↑ ②CuO+H2===Cu+H2O

③Ba(OH)2+H2SO4 ===BaSO4↓+2H2O ④ 2Fe + 3Cl2 = 2FeCl3

1、根据反应物和生成物的类别以及反应前后物质种类的多少:

①属于分解反应 ;②属于置换反应;③属于复分解反应;④属于化合反应

2、根据反应中是否有电子转移:

②、④属于氧化还原反应;①、③属于非氧化还原反应

3、根据反应中是否有自由移动的电子参加:

①、②、④属于非离子反应;③属于离子反应

一、化学反应的分类

化合反应

根据反应物和生成物 分解反应

的类别和种类可分为 置换反应

复分解反应

化 根据反应中是否有 氧化还原反应

学 电子转移可分为 非氧化还原反应

反 根据反应中是否有自由 离子反应

应 移动的电子参加可分为 非离子反应

据化学反应中热量 放热反应

变化情况可分为 吸热反应

上述反应②、④属于氧化还原反应,请用双线桥法表示电子转移方向和数目,并指出氧化剂和还原剂,氧化产物和还原产物。

氧化还原反应的本质是电子的转移,由此而产生的其他概念及转化关系规纳如下:

二、氧化还原反应概念及转化关系

氧化剂→具有氧化性→得电子→被还原→发生还原反应→化合价降低→还原产物

还原剂→具有还原性→失电子→被氧化→发生氧化反应→化合价升高→氧化产物

氧化还原反应的实质是电子的转移,特征是反应前后元素的化合价发生了变化。我们判断某反应是否为氧化还原反应可根据反应前后元素的化合价是否发生了变化这一特征。氧化还原反应中的概念一般是成对出现的,理清概念是解决问题的关键。

三、氧化还原反应的基本规律

1、表现性质规律

当元素具有可变化合价时,一般处于最高价态时只具有氧化性,处于最低价时只具有还原性,处于中间价态时既具有氧化性又有还原性。

2、性质强弱规律

(1)在氧化还原反应中:

强氧化剂+强还原剂=弱氧化剂(氧化产物)+弱还原剂(还原产物)

(2)一般来说,含有同种元素不同价态的物质,价态越高氧化性越强(氯的含氧酸除外),价态越低还原性越强。

3、价态归中规律

含有不同价态同种元素的物质,发生氧化还原反应,该元素价态的变化一定遵循“高价+低价→中间价”,而不会出现交错现象。

4、反应先后规律

同一氧化剂与含有多种还原剂(物质的量浓度相同)的溶液反应时,首先被氧化的是还原性较强的物质;同一还原剂与含有多种氧化剂(物质的量浓度相同)的溶液反应时,首先被还原的是氧化性较强的物质。

反应③属于离子反应,请写出离子反应方程式

反应③的离子反应方程式还能表示哪些物质间的反应?

离子方程式书写的基本规律要求。

四、离子方程式

(1)合事实:离子反应要符合客观事实,不可臆造产物及反应。

(2)式正确:化学式与离子符号使用正确合理。

(3)号实际:“=”“”“→”“↑”“↓”等符号符合实际。

(4)两守恒:两边原子数、电荷数必须守恒(氧化还原反应离子方程式中氧化剂得电子总数与还原剂失电子总数要相等)。

(5)明类型:依据离子反应原理,分清类型,总结方法技巧。

(6)检查细:结合书写离子方程式过程中易出现的错误,细心检查。

五、例题分析

例1下列化工生产过程所发生的反应不属于氧化还原反应的是( )

A.用油脂制肥皂 B.用铝土矿制金属铝

C.用氯气和消石灰制漂白剂 D.用氢气和氮气合成氨

解析:判断氧化还原反应的最简单的方法是看反应前后元素的化合价是否发生了变化。B中:Al2O3→Al,C中Cl2→CaCl2+Ca(ClO)2,D中N2+H2→NH3,均有化合价变化,故都属于氧化还原反应。选A。

例2已知在某温度时发生如下三个反应:⑴ C+CO2=2CO ⑵ C+H2O=CO+H2 ⑶ CO+H2O=CO2+H2 由此可以判断,在该温度下C、CO、H2的还原性强弱顺序是( )

A C>CO>H2 B CO>C>H2 C C>H2>CO D CO>H2>C

解析:对于反应:氧化剂+还原剂=氧化产物+还原产物,有以下规律:还原剂的还原性>还原产物的还原性,氧化剂的氧化性>氧化产物的氧化性。由反应式(1)可知C>CO,由反应式(2)可知C>H2, 由反应式(3)可知CO>H2。本题正确答案为A。

例3、G、Q、X、Y、Z均为氯的含氧化合物,我们不了解它们的分子式(或化学式),但知道它们在一定条件下具有如下的转换关系(未配平):(1)G Q+NaCl (2)Q+H2O X+H2 (3)Y+NaOH G+Q+H2O (4)Z+NaOH Q+X+H2O这五种化合物中氯的化合价由低到高的顺序为 ( )

A.QGZYX B.GYQZX C.GYZQX D.ZXGYQ

解析:根据氧化还原反应的特征可知,氧化还原反应中元素化合价有升必有降。由(1)得Q>G,因为该反应为歧化反应,G中氯元素的化合价必介于Q和-1价氯之间。同理由(3)结合(1)得Q>Y>G,由(2)得X>Q,由(4)结合(2)得X>Z>Q。本题正确答案为B。

例4、下列离子方程式正确的是( )

A.氯化铝溶液与氨水反应:Al3++3OH-=Al(OH)3↓

B.磷酸二氢钙溶液跟足量NaOH溶液反应:

3Ca2++2H2PO4-+4OH-=Ca3(PO4)2↓+4H2O

C.硝酸亚铁溶液中滴入稀硫酸:3Fe2++NO3-+4H+=3Fe3++NO↑+2H2O

D.硫氢化钠水解:HS-+H2O=H2S↑+OH

解析:本题涉及溶液中电解质强弱、离子反应规律、氧化还原反应、盐的水解等知识,需要对各选项仔细全面地分析,才能正确解答。

A中氨水是弱电解质,应写化学式;B中NaOH足量,Ca(H2PO4)2全部参加反应,式中Ca2+与H2PO4-不符合Ca(H2PO4)2化学式中的比例,故不正确;C中 在酸性条件下具有氧化性,正确。D中HS-水解程度很小。不能用“=”、“↑”,故不正确。答案为C。

例5、(1)向NaHSO4溶液中,逐滴加入Ba(OH)2溶液至中性,请写出发生反应的离子方程式_________________________。

(2)在以上中性溶液中,继续滴加Ba(OH)2溶液,请写出此步反应的离子方程式______________________________。

解析:本题是一个“反应进程”的试题。解题的关键是“中性”。即加入的Ba(OH)2溶液中OH-恰好与H+完全反应。再继续滴加Ba(OH)2溶液时,要分析此溶液中还有什么离子能继续反应。

答案:(1)2H++SO42-

+Ba2++2OH-=BaSO4↓+2H2O

(2)Ba2++SO42-=BaSO4↓

例6、下列各组中的离子,能在溶液中大量共存的是( )

A.K+、Ag+、、Cl- B.Ba2+、、CO32-、OH- C.Mg2+、Ba2+、OH-、NO3- D.H+、K+、CO32-、SO42- E.Al3+、Fe3+、SO42-、Cl- F.K+、H+、NH4+、OH-

解析: A组中:Ag++Cl-=AgCl↓ B组中, + =BaCO3↓

C组中,Mg2++2OH-=Mg(OH2) ↓ D组中,2H++CO32-=CO2↑+H2O

E组中,各种离子能在溶液中大量共存。

F组中,NH4+与OH-能生难电离的弱电解质NH3·H2O,甚至有气体逸出。

NH4++OH- NH3·H2O或NH4++OH-=NH3↑+H2O

答案:E
