人教版高中地理必修2北京的自行車是多了還是少了精品教案
提問：城市環(huán)境污染源主要有哪些？有些同學(xué)基本同意自行車多是加劇南京空氣污染的間接原因，你同意他們的觀點(diǎn)嗎？在學(xué)生回答的基礎(chǔ)上，教師進(jìn)行歸納小結(jié)：工業(yè)和交通是城市環(huán)境的主要污染源。而自行車是一種綠色交通工具，既環(huán)保又經(jīng)濟(jì)。只有當(dāng)它在某些機(jī)動車和非機(jī)動車不分的地段，影響車輛行駛速度的時候，它才可能成為加劇空氣污染的間接原因。問：那我們針對交通工具對環(huán)境造成的影響，有什么解決方法嗎？歸納小結(jié)：? 實(shí)施減少汽車尾氣污染的技術(shù)措施? 加強(qiáng)道路綠化? 合理規(guī)劃城市道路，提高車速? 制定相關(guān)法規(guī)嚴(yán)禁各種車輛違規(guī)鳴喇叭? 在噪音嚴(yán)重的地區(qū)設(shè)置先進(jìn)的隔音設(shè)施總結(jié)：通過前面的分析我們知道了自行車過多并不是造成北京交通擁擠的主要原因，但自行車多并且不遵守交通規(guī)則的確是造成交通擁堵的一個原因。從這方面來講，在一些混合車道地段，自行車是造成空氣污染加劇的間接原因。那么在北京到底是應(yīng)該鼓勵自行車的發(fā)展還是限制自行車的發(fā)展呢？
人教版新課標(biāo)高中物理必修1伽利略對自由落體運(yùn)動的研究教案2篇
猜想：既然物體下落過程中的運(yùn)動情況與物體質(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，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單的變速運(yùn)動.他設(shè)想，最簡單的變速運(yùn)動的速度應(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時間來說是均勻的，即經(jīng)過相等的時間，速度的變化相等；另一種是速度的變化對位移來說是均勻的，即經(jīng)過相等的位移，速度的變化相等.伽利略假設(shè)第一種方式最簡單，并把這種運(yùn)動叫做勻變速運(yùn)動.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.

三、想象畫面，把握意境1.指導(dǎo)想象學(xué)習(xí)陶淵明的《歸園田居》我們腦海中自然會出現(xiàn)一幅幅的畫面，比如他歸家后的生活場景，我們會想象“榆柳”是如何遮蔽房屋的，而“桃李”又是如何摘種在房前的。我們會想象村落是如何在薄霧中若隱若現(xiàn)的，想象炊煙是如何裊裊升起的。《涉江采芙蓉》一詩只有8句話，更需要我們展開想象，去構(gòu)畫場景，這樣才能深入詩歌，體會到詩歌的味道。2.學(xué)生想象要求學(xué)生閉目想象1分鐘。3.學(xué)生展示想象結(jié)果（抽三四個學(xué)生回答即可）4.老師指導(dǎo)糾正學(xué)生想象不合理之處。要注意的地方：“江”可能學(xué)生會想象成小溪流、小池塘。“蘭澤”可能學(xué)生理解成“湖泊”。注意字詞“還顧”“漫浩浩”中隱含的情感，注意“離居”中流露的愁怨。5.時間允許的話，老師讀自己的下水作文。
