人教版高中地理必修1全球氣候變化教案
科學(xué)家預(yù)測(cè)，就地區(qū)而言，位于低緯度的大部分國家，農(nóng)作物的產(chǎn)量將減少；而位于高緯度的國家，農(nóng)作物產(chǎn)量有可能增加。由于不少發(fā)展中國家位于低緯度地區(qū)，因此，氣候變化的這種區(qū)域差異性，可能會(huì)使發(fā)展中國家所面臨的問題更為嚴(yán)峻。板書：3全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。介紹：全球變暖會(huì)影響整個(gè)水循環(huán)過程，可能使蒸發(fā)加大，改變區(qū)域降水量和降水分布格局，增加降水極端異常事件的發(fā)生，導(dǎo)致洪澇、干旱災(zāi)害的頻次和強(qiáng)度增加，以及地表徑流發(fā)生變化。隨著徑流減少，蒸發(fā)增強(qiáng)，全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。轉(zhuǎn)折：既然全球變暖會(huì)引起很多不利影響，那么作為人類應(yīng)如何面對(duì)這一挑戰(zhàn)呢？這就是我們要討論的第三個(gè)問題。板書：三、氣候變化的適應(yīng)對(duì)策討論：請(qǐng)大家閱讀結(jié)合教材P53氣候變化的適應(yīng)對(duì)策部分討論人類應(yīng)如何面對(duì)全球變暖這一問題 呢？
人教版新課標(biāo)高中物理必修1彈力教案2篇
一般情況下，凡是支持物對(duì)物體的支持力，都是支持物因發(fā)生形變而對(duì)物體產(chǎn)生彈力。所以支持力的方向總是垂直于支持面而指向被支持的物體。例1：放在水平桌面上的書書由于重力的作用而壓迫桌面，使書和桌面同時(shí)發(fā)生微小形變，要恢復(fù)原狀，對(duì)桌面產(chǎn)生垂直于桌面向下的彈力f1，這就是書對(duì)桌面的壓力；桌面由于發(fā)生微小的形變，對(duì)書產(chǎn)生垂直于書面向上的彈力f2，這就是桌面對(duì)書的支持力。學(xué)生分析：靜止地放在傾斜木板上的書，書對(duì)木板的壓力和木板對(duì)書的支持力。并畫出力的示意圖。結(jié)論：壓力、支持力都是彈力。壓力的方向總是垂直于支持面而指向被壓的物體，支持力的方向總是垂直于支持面而指向被支持的物體。引導(dǎo)學(xué)生分析靜止時(shí)，懸繩對(duì)重物的拉力及方向。引導(dǎo)得出：懸掛物由于重力的作用而拉緊懸繩，使重物、懸繩同時(shí)發(fā)生微小的形變。重物由于發(fā)生微小的形變，對(duì)懸繩產(chǎn)生豎直向下的彈力f1，這是物對(duì)繩的拉力；懸繩由于發(fā)生微小形變，對(duì)物產(chǎn)生豎直向上的彈力f2，這就是繩對(duì)物體的拉力。
