三、作出速度－時間圖像（v－t圖像）1、確定運動規(guī)律最好辦法是作v－t圖像，這樣能更好地顯現(xiàn)物體的運動規(guī)律。2、x y x1 x2 y2 y1 0討論如何在本次實驗中描點、連線。（以時間t為橫軸，速度v為縱軸，建立坐標(biāo)系，選擇合適的標(biāo)度，把剛才所填表格中的各點在速度－時間坐標(biāo)系中描出。注意觀察和思考你所描畫的這些點的分布規(guī)律，你會發(fā)現(xiàn)這些點大致落在同一條直線上，所以不能用折線連接，而用一根直線連接，還要注意連線兩側(cè)的點數(shù)要大致相同。）3、若出現(xiàn)了個別明顯偏離絕大部分點所在直線的點，該如何處理？（對于個別明顯偏離絕大部分點所在直線的點，我們可以認(rèn)為是測量誤差過大、是測量中出現(xiàn)差錯所致，將它視為無效點，但是在圖像當(dāng)中仍應(yīng)該保留，因為我們要尊重實驗事實，這畢竟是我們的第一手資料，是原始數(shù)據(jù)。）4、怎樣根據(jù)所畫的v－t圖像求加速度？(從所畫的圖像中取兩個點，找到它們的縱、橫坐標(biāo)（t1，v1）、（t2，v2），然后代入公式，求得加速度，也就是直線的斜率。在平面直角坐標(biāo)系中，直線的斜率

【設(shè)計思路】新課程十分強(qiáng)調(diào)科學(xué)探究在科學(xué)課程中的作用,應(yīng)該說科學(xué)探究是這次課程改革的核心。我覺得：科學(xué)探究不一定是要讓學(xué)生純粹地通過實驗進(jìn)行探究，應(yīng)該說科學(xué)探究是一種科學(xué)精神,學(xué)生只要通過自己的探索和體驗,變未知為已知,這樣的教學(xué)活動也是科學(xué)探究。本節(jié)課是概念教學(xué)課,讓學(xué)生純粹地通過實驗進(jìn)行探究是不太合適的。但通過學(xué)生自己的探索和體驗,變未知為已知還比較合適。本節(jié)課的設(shè)計就是基于這樣的出發(fā)點,在引出加速度的概念時低臺階,步步深入,充分激活學(xué)生的思維,是學(xué)生思維上的探究。通過復(fù)習(xí)前邊速度時間圖像，從而得到從圖像上得到加速度的方法，為加深加速度概念和相關(guān)知識的理解有配套了相應(yīng)練習(xí)題目，做到強(qiáng)化練習(xí)的目的?！窘虒W(xué)目標(biāo)】知識與技能1．理解加速度的意義，知道加速度是表示速度變化快慢的物理量．知道它的定義、公式、符號和單位，能用公式a=△v/△t進(jìn)行定量計算．2．知道加速度與速度的區(qū)別和聯(lián)系，會根據(jù)加速度與速度的方向關(guān)系判斷物體是加速運動還是減速運動．

3、若出現(xiàn)了個別明顯偏離絕大部分點所在直線的點，該如何處理？（對于個別明顯偏離絕大部分點所在直線的點，我們可以認(rèn)為是測量誤差過大、是測量中出現(xiàn)差錯所致，將它視為無效點，但是在圖像當(dāng)中仍應(yīng)該保留，因為我們要尊重實驗事實，這畢竟是我們的第一手資料，是原始數(shù)據(jù)。）4、怎樣根據(jù)所畫的v－t圖像求加速度？(從所畫的圖像中取兩個點，找到它們的縱、橫坐標(biāo)（t1，v1）、（t2，v2），然后代入公式，求得加速度，也就是直線的斜率。在平面直角坐標(biāo)系中，直線的斜率四、實踐與拓展例1、在探究小車速度隨時間變化規(guī)律的實驗中，得到一條記錄小車運動情況的紙帶，如圖所示。圖中A、B、C、D、E為相鄰的計數(shù)點，相鄰計數(shù)點的時間間隔為T＝0.1s。⑴根據(jù)紙帶上的數(shù)據(jù)，計算B、C、D各點的數(shù)據(jù)，填入表中。

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.
