[教案參考] 高中地理教案

一名優(yōu)秀的教師在教學(xué)方面無論做什么事都有計(jì)劃和準(zhǔn)備，作為高中教師就要精心準(zhǔn)備好合適的教案。教案可以更好的幫助學(xué)生們打好基礎(chǔ)，幫助高中教師提高自己的教學(xué)質(zhì)量。那么怎么才能寫出優(yōu)秀的高中教案呢？急你所急，小編為朋友們了收集和編輯了“[教案參考] 高中地理教案”，歡迎大家借鑒與參考，希望對(duì)大家有所幫助。

[教學(xué)目標(biāo)]

1.用圖例說明天體系統(tǒng)的層次，以及地球在宇宙中的位置。

2.運(yùn)用圖表資說明地球是太陽系中一顆既普通又特殊的行星。

3.分析地球的宇宙位置及自身?xiàng)l件，理解地球上出現(xiàn)生命的原因。

[教學(xué)重點(diǎn)]

1、地球在宇宙中的位置。

2、地球的普通性和特殊性。

[教學(xué)難點(diǎn)]

地球上存在生命的原因

[教學(xué)過程]

（導(dǎo)入新課）太陽的東升西落、晝夜交替、斗轉(zhuǎn)星移這些現(xiàn)象我們都是很熟悉的，你們當(dāng)中有誰知道在地球上這些現(xiàn)象為什么會(huì)產(chǎn)生嗎？地球上為什么會(huì)有生命？其它星球上有沒有生命呢？這就是我們這節(jié)課里將要學(xué)習(xí)的內(nèi)容。

（講授新課）

一、地球在宇宙中的位置

1、宇宙是由物質(zhì)組成的

①天體類型

A、恒星 由熾熱氣體組成，自身能發(fā)光發(fā)熱的球狀或類似球狀的天體

B、星云 由氣體和塵埃組成的呈云霧狀外表的天體

C、行星 在橢圓形軌道上環(huán)繞太陽運(yùn)行的、近似球形的天體。自身不能發(fā)光。

D、衛(wèi)星 環(huán)繞行星運(yùn)行的、質(zhì)量很小的一種天體。月球是地球的惟一的一顆衛(wèi)星。

E、流星體 行星際空間的塵粒和固體小塊。沿同一軌道繞太陽運(yùn)行的大群流星體，稱為流星群，闖入地球大氣層的流星體，因同大氣摩擦而產(chǎn)生的光跡，劃過長空，好像從空中的某一點(diǎn)向外散射開，這種現(xiàn)象叫做流星體。

F、彗星 在扁長軌道上繞太陽運(yùn)行的一種質(zhì)量較小的天體，呈云霧狀。

此外，還有其它的星際物質(zhì)。其中，恒星和星云是兩種最基本的天體

（附：練習(xí)鞏固對(duì)天體特征知識(shí)的理解和認(rèn)識(shí)）

②天體系統(tǒng)的層次

任何天體在宇宙中都有自己的位置，各天體之間相互吸引相互繞轉(zhuǎn)，形成天體系統(tǒng)。各級(jí)天體系統(tǒng)的組成如下：

A、地月系 月球繞地球轉(zhuǎn)動(dòng)形成地月系。地球是中心天體，月球是地球的惟一的天然衛(wèi)星。

B、太陽系 太陽、地球和其他行星及其衛(wèi)星、小行星、彗星、流星體、星際物質(zhì)構(gòu)成太陽系。

C、銀河系 太陽系和其他恒星系構(gòu)成銀河系。在銀河系以外，還有大約10億個(gè)同其相類似的天體系統(tǒng)，人稱河外星系。

D、總星系 銀河系和現(xiàn)階段所能觀測(cè)到的河外星系，統(tǒng)稱為總星系。

天體系統(tǒng)共分為四個(gè)等級(jí)，按照從低級(jí)到高給的順序依次為：行星系——恒星系——星系——總星系

二、地球是太陽系中一顆既普通又特殊的行星

1、地球是一顆普通的行星

①八大行星的運(yùn)動(dòng)特征：同向性、共面性、近圓性

②八大行星的結(jié)構(gòu)特征

劃分依據(jù)：距日距離、質(zhì)量、體積

分類：類地行星（水金地火）、巨行星（木土）、遠(yuǎn)日行星（天海）

2、地球是一顆特殊的行星

表現(xiàn)：地球上存在生命

原因：A、日地距離適中——適于生命姓的發(fā)展的溫度條件

B、質(zhì)量和體積適中——吸附大氣，形成包圍地球的大氣層

C、地球的內(nèi)部結(jié)構(gòu)和物質(zhì)運(yùn)動(dòng)——原始海洋的形成。

地球是太陽系中目前已知的惟一一顆適合生物生存和繁衍的行星，究其原因，除其所處的位置及自身?xiàng)l件外，還和它所處的宇宙環(huán)境的很大的關(guān)系。在太陽系中，大小行星繞日公轉(zhuǎn)方向一致，而且繞日公轉(zhuǎn)軌道幾乎在同一個(gè)平面上，大小行星各行其道，互不干擾，使地球處于一種比較安全的宇宙環(huán)境之中。

[課堂小結(jié)]

1.用圖例說明天體系統(tǒng)的層次，以及地球在宇宙中的位置

2.運(yùn)用圖表資說明地球是太陽系中一顆既普通又特殊的行星

3.分析地球的宇宙位置及自身?xiàng)l件，理解地球上出現(xiàn)生命的原因

[課堂練習(xí)]

針對(duì)每個(gè)教學(xué)目標(biāo)而選取的題目，有助于學(xué)生理解所學(xué)知識(shí)并對(duì)所學(xué)知識(shí)鞏固。

[優(yōu)質(zhì)教案] 高中主題教案壹篇

一名優(yōu)秀的教師在每次教學(xué)前有自己的事先計(jì)劃，作為教師就要在上課前做好適合自己的教案。教案可以讓學(xué)生們能夠在上課時(shí)充分理解所教內(nèi)容，幫助授課經(jīng)驗(yàn)少的教師教學(xué)。優(yōu)秀有創(chuàng)意的教案要怎樣寫呢？小編收集并整理了“[優(yōu)質(zhì)教案] 高中主題教案壹篇”，歡迎您參考，希望對(duì)您有所助益！

【活動(dòng)目的】為了使全班同學(xué)進(jìn)一步了解、理解新的《中學(xué)生日常行為規(guī)范》要求，增強(qiáng)班級(jí)凝聚力，使學(xué)生能把規(guī)范的要求內(nèi)化為自己自覺的行動(dòng)，做一個(gè)遵規(guī)守紀(jì)、誠實(shí)守信、勤奮向上的中學(xué)生。

【活動(dòng)簡(jiǎn)介】以學(xué)生學(xué)習(xí)行為規(guī)范為中心，通過生活實(shí)例窺探、行規(guī)討論交流、反面案例啟示、文明倡議書簽名等一系列程序活動(dòng)對(duì)本班學(xué)生進(jìn)行行為規(guī)范教育。

【活動(dòng)要求】注重人人參與，講究活動(dòng)秩序，聯(lián)系實(shí)際。

【活動(dòng)過程】

主持人語：

班主任：同學(xué)們，今天我們大家在這個(gè)教室里開展開學(xué)以來第一次班隊(duì)活動(dòng)，我想，咱們開學(xué)已經(jīng)一個(gè)月多了，我不知道大家對(duì)中學(xué)生日常行為規(guī)范是否有所了解，又是否落實(shí)到行動(dòng)中了.今天我們就針對(duì)這個(gè)問題舉辦一次班隊(duì)活動(dòng).

（4）吃飯時(shí)要做到邊吃邊聊，這樣才越吃越香（╳）

（5）手中有廢紙或其他垃圾隨手丟在路邊，反正沒有人看見（╳）

（6）按時(shí)到校，不遲到，不早退，不曠課。（√）

（7）上課太累人了，我趴在桌子上睡一會(huì)兒再說（╳）

（8）別人不小心踩到你的腳，立即給你道歉了，你說沒關(guān)系（√）

（9）認(rèn)真值日，保持教室、校園整潔優(yōu)美。不在教室和校園內(nèi)追逐打鬧喧嘩，維護(hù)學(xué)校良好秩序（√）

（10）晚上休息時(shí)間到了，我睡不著，干脆出去散散步回來再睡（╳）

（11）前面是我們的老師，我們趕緊繞道而行吧，免得給他打招呼（╳）

（12）不說臟話，不罵人，不打架，不賭博。不涉足未成年人不宜的活動(dòng)和場(chǎng)所（√）

（13）這些作業(yè)我不會(huì)做，不如拿同桌的來抄抄吧。（╳）

（14）排隊(duì)時(shí)可以大聲喧嘩、勾肩搭背，只要不被老師看見就行了。（╳）

三、答題競(jìng)賽：（全體同學(xué)參與，贏取小獎(jiǎng)品）

（班長）非常感謝三組同學(xué)的表演，為了檢驗(yàn)同學(xué)們今天的收獲，下面我們開展答題競(jìng)賽活動(dòng)，請(qǐng)同學(xué)們積極參與，看誰回答的有快有正確。
