四、速度和速率學(xué)生閱讀教材第18頁相應(yīng)部分的知識(shí)點(diǎn)，讓學(xué)生總結(jié)．生：速度既有大小，又有方向，是矢量，速度的大小叫速率，教師引導(dǎo)學(xué)生看教材第18頁圖1．3—2．觀察汽車的速度計(jì)，討論后說出你從表盤上獲取的有用信息。生：汽車的速率．指針指在相應(yīng)數(shù)字的瞬間，就表示汽車在那一瞬時(shí)的速率是那個(gè)值．生：還可以從表盤上直接讀出公里里程．師：日常生活中的“速度”有時(shí)指速度，也有時(shí)指速率，要看實(shí)際的物理情景。[討論與交流]甲、乙兩位同學(xué)用不同的時(shí)間圍繞操場(chǎng)跑了一圈，都回到了出發(fā)點(diǎn)，他們的平均速度相同嗎?怎樣比較他們運(yùn)動(dòng)的快慢?學(xué)生討論，體驗(yàn)平均速度的缺陷，引入平均速率。生1：位移都是零，平均速度等于位移跟發(fā)生這段位移所用時(shí)間的比值，所以他們的平均速度都是零。生2：即使一位同學(xué)站在原地不跑，他的平均速度也是零啊，可我們運(yùn)動(dòng)會(huì)上不是這樣比快慢的，如果這樣，那多不公平啊?

教學(xué)重點(diǎn)1．自由落體運(yùn)動(dòng)的概念及探究自由落體運(yùn)動(dòng)的過程。2．掌握自由落體運(yùn)動(dòng)規(guī)律，并能運(yùn)用其解決實(shí)際問題。教學(xué)難點(diǎn)演示實(shí)驗(yàn)和探究實(shí)驗(yàn)的技巧及自由落體運(yùn)動(dòng)規(guī)律的得出.教學(xué)過程設(shè)計(jì)思想：1、 先用游戲激發(fā)學(xué)生學(xué)習(xí)興趣，順理成章地研究落體運(yùn)動(dòng)；2、 通過演示實(shí)驗(yàn)讓學(xué)生自己總結(jié)出物體下落快慢不同的主要原因是空氣阻力，從而猜想若沒有空氣阻力會(huì)怎樣；3、 用牛頓管實(shí)驗(yàn)驗(yàn)證猜想，引入了新的理想運(yùn)動(dòng)模型：自由落體運(yùn)動(dòng)。講述1971年宇航員做的實(shí)驗(yàn)，加深印象；4、 了解地球表面物體下落運(yùn)動(dòng)近似成自由落體運(yùn)動(dòng)的條件；5、 著手研究自由落體運(yùn)動(dòng)的規(guī)律，利用打點(diǎn)計(jì)時(shí)器進(jìn)行研究，得到結(jié)論；6、 總結(jié)自由落體運(yùn)動(dòng)特點(diǎn)及重力加速度；7、 應(yīng)用訓(xùn)練
人教版新課標(biāo)高中物理必修1伽利略對(duì)自由落體運(yùn)動(dòng)的研究教案2篇
猜想：既然物體下落過程中的運(yùn)動(dòng)情況與物體質(zhì)量無關(guān)，那么為什么在現(xiàn)實(shí)生活中，不同物體的落體運(yùn)動(dòng)，下落快慢不同呢？我們能否猜想是由于空氣阻力的作用造成的呢？如果沒有空氣阻力將會(huì)怎樣呢？學(xué)生討論后回答.三、猜想與假說伽利略認(rèn)為，自由落體是一種最簡(jiǎn)單的變速運(yùn)動(dòng).他設(shè)想，最簡(jiǎn)單的變速運(yùn)動(dòng)的速度應(yīng)該是均勻變化的.但是，速度的變化怎樣才算均勻呢?他考慮了兩種可能：一種是速度的變化對(duì)時(shí)間來說是均勻的，即經(jīng)過相等的時(shí)間，速度的變化相等；另一種是速度的變化對(duì)位移來說是均勻的，即經(jīng)過相等的位移，速度的變化相等.伽利略假設(shè)第一種方式最簡(jiǎn)單，并把這種運(yùn)動(dòng)叫做勻變速運(yùn)動(dòng).四、實(shí)驗(yàn)驗(yàn)證實(shí)驗(yàn)驗(yàn)證是檢驗(yàn)理論正確與否的唯一標(biāo)準(zhǔn).任何結(jié)論和猜想都必須經(jīng)過實(shí)驗(yàn)驗(yàn)證，否則不成理論.猜想或假說只有通過驗(yàn)證才會(huì)成為理論.所謂實(shí)驗(yàn)驗(yàn)證就是任何人，在理論條件下去操作都能到得實(shí)驗(yàn)結(jié)果，它具有任意性，但不是無條件的，實(shí)驗(yàn)是在一定條件下的驗(yàn)證，而與實(shí)際有區(qū)別.

演示實(shí)驗(yàn)1、將一張紙和一張金屬片在同一高度同時(shí)釋放，結(jié)果金屬片先著地。教師不發(fā)表意見，繼續(xù)做實(shí)驗(yàn)。分別將實(shí)驗(yàn)內(nèi)容和實(shí)驗(yàn)結(jié)果板書在黑板上。2、將剛才的紙片緊緊捏成一團(tuán)，再次與硬幣同時(shí)釋放，結(jié)果兩者幾乎同時(shí)落地。3、將兩個(gè)完全一樣的紙片，一個(gè)捏成團(tuán)，一個(gè)平展，則紙團(tuán)下落快。師：物體下落快慢是由質(zhì)量決定嗎？生：不是的！師：為什么這樣說？生：第2個(gè)實(shí)驗(yàn)和第三實(shí)驗(yàn)都說明了這個(gè)問題，特別是第3個(gè)問題，質(zhì)量一樣卻下落有快慢之分。師：那你現(xiàn)在覺得物體下落快慢由什么因素決定呢？生：我想應(yīng)該是空氣阻力。猜想師：如果影響物體下落快慢的因素是空氣阻力，那么在沒有空氣阻力，物體的下落快慢應(yīng)該是一樣的，這種猜想是不是正確呢？我們來做一個(gè)實(shí)驗(yàn)驗(yàn)證一下。

生：還可以從表盤上直接讀出公里里程．師：日常生活中的“速度”有時(shí)指速度，也有時(shí)指速率，要看實(shí)際的物理情景。[討論與交流]甲、乙兩位同學(xué)用不同的時(shí)間圍繞操場(chǎng)跑了一圈，都回到了出發(fā)點(diǎn)，他們的平均速度相同嗎?怎樣比較他們運(yùn)動(dòng)的快慢?學(xué)生討論，體驗(yàn)平均速度的缺陷，引入平均速率。生1：位移都是零，平均速度等于位移跟發(fā)生這段位移所用時(shí)間的比值，所以他們的平均速度都是零。生2：即使一位同學(xué)站在原地不跑，他的平均速度也是零啊，可我們運(yùn)動(dòng)會(huì)上不是這樣比快慢的，如果這樣，那多不公平啊?師：平均速度v=Δx/Δt，甲、乙的位移都為零，所以他們的平均速度也都等于零．在這里平均速度無法顯示他們運(yùn)動(dòng)快慢的不同，要用到另一物理量：平均速率．平均速率等于物體運(yùn)動(dòng)通過的路程跟所用時(shí)間的比值．他們兩人通過的路程相同且都不為零，但所用時(shí)間不同．顯然用時(shí)短的運(yùn)動(dòng)得快，也就是平均速率大．生：這不是我們初中學(xué)過的速度嗎?

新人教版高中英語必修2Unit 2 Wildlife Protection-Listening &Speaking＆Talking教案
Listening and Speaking introduces the topic of “how to save endangered wildlife and help wildlife in their neighborhood.” Due to the continuous deterioration of the living environment, a large number of wild animals are always facing the threat of endangered or extinction. Listening and speaking period enables students to understand the fact and reason why wild species are disappearing from the earth at an amazing speed, and realize that human beings ought to enhance the awareness of protecting wild species as soon as possible.Listening and Talking introduces the theme of " how to help wildlife in Ss’ neighborhood.". Now there are many volunteers who spontaneously protect wild animals, carry out various activities according to local conditions, and contribute their own strength to local animal protection with practical actions. Middle school students are also enthusiastic participants. They organize activities in their spare time, and take this opportunity to make friends, broaden their horizons, cultivate team spirit and communication skills. This section describes a bird watching activity organized by several middle school students of Bird watching Club. It aims to stimulate students' interest, improve their understanding of bird watching activities, and use the language structure of “being used for; in order to, so as to, to, so that, in order that ” to express the purpose for communication and discussion.1. Guide students to understand the content of listening texts in terms of using visuals to predict content.2. Cultivate students' ability to guess the meaning of words in listening; discuss with their peers how to save endangered wildlife and help wildlife in their neighborhood.3. Instruct students to use functional sentences of the dialogue such as “I am concerned about…” “what do you know about the endangered animals in…" and so on to talk about one of the endangered animals.

The theme of this unit is human and nature, focusing on the theme of wildlife protection. Nature is a complex ecosystem, in which there are delicate balance between animals and plants. Because of the role of the food chain, the extinction of one species will produce influence, causing a series of chain reaction. Large scale extinction of species will have a serious and even irreversible impact on the ecosystem, resulting in immeasurable losses. Therefore, it is of great significance to protect wild species. To protect wild species is to protect human beings themselves. The motto of this unit is "when the buying stops, the killing can too,” which is a public service advertising slogan to protect wildlife. It tells people that every rhinoceros horn, every fur, every bowl of shark fin soup, every Ivory product, and every tiger bone product, etc. consumed by human beings, are innocent wild animals slaughtered behind them.
