2019年(秋)六年級(jí)科學(xué)上冊(cè) 3.6《人類對(duì)地表變化 的影響》教案 湘教版 教學(xué)目標(biāo) 科學(xué)探究 1、通過對(duì)圍湖造田的利弊分析，培養(yǎng)學(xué)生綜合分析的能力。 2、繼續(xù)提高學(xué)生搜集資料的能力。 情感態(tài)度與價(jià)值觀 1、意識(shí)到人類對(duì)地表變化的影響有利有弊，提高對(duì)這一問題的關(guān)注度和敏感性。 2、意識(shí)到人類必須遵循自然規(guī)律改變地表，才能實(shí)現(xiàn)人與自然的和諧相處。 科學(xué)知識(shí) 1、了解人類活動(dòng)對(duì)地表改變的影響。 2、了解圍湖造田的利弊。 教學(xué)準(zhǔn)備 課前布置學(xué)生收集因人類活動(dòng)造成地表改變、水土流失的典型事例。 教學(xué)重點(diǎn) 指導(dǎo)學(xué)生通過收集和整理資料、召開辯論會(huì)等方式來探究“人類活動(dòng)隊(duì)地表的影響”的問題。 教學(xué)難點(diǎn) 人類那些改造地表的活動(dòng)是對(duì)人類有利的，哪些是不利的 教學(xué)內(nèi)容 一、教學(xué)導(dǎo)入 1、提問：在改變地表形態(tài)的各種力量中，除了各種自然力量外，還有人為的力量，請(qǐng)大家列舉人類的哪些活動(dòng)在不斷改變著地表形態(tài)？ 2、學(xué)生回答。 3、過渡：人類的活動(dòng)只是改變了地表形態(tài)嗎？有沒有其它的影響？ 二、閱讀指南車信箱 1、指導(dǎo)學(xué)生閱讀教材指南車信箱提供的資料。 2、組織學(xué)生課前搜集的資料傳閱、交流。 3、宣讀介紹人類改變地表的典型事例，或者相互交換、傳閱搜集到的資料。 4、明白：人類活動(dòng)是一種特殊的外力作用。因?yàn)殡S著工農(nóng)業(yè)和科學(xué)技術(shù)飛速發(fā)展，人類活動(dòng)的深度和廣度與日俱增。對(duì)地表形態(tài)的影響是十分可觀的。如我國(guó)勞動(dòng)人民根據(jù)自然規(guī)律和社會(huì)需要，長(zhǎng)期的經(jīng)濟(jì)活動(dòng)塑造了許多地表形態(tài)特征非常明顯的人工地貌——梯田、?；~塘、黃土淤泥壩、圍海造田等。世界上不少大城市如墨西哥、東京、大頤、上海等，由于長(zhǎng)期過量開采地下水而產(chǎn)生地面沉降，上海市至1965年累計(jì)沉降達(dá)2.6米；有人統(tǒng)計(jì)至1965年，地球大陸面積的8%已為各類工程所覆蓋，xx年面積將擴(kuò)大近一倍；還有在礦產(chǎn)開采、農(nóng)業(yè)生產(chǎn)、軍事活動(dòng)和其他工程建設(shè)中，創(chuàng)造出許多新的地貌形態(tài)。（人類活動(dòng)對(duì)地表形態(tài)的改變也具有雙重性，一是創(chuàng)造性地合理利用或改造惡劣環(huán)境；另一則是破壞性地引起災(zāi)害的發(fā)生。）我們要合理利用和保護(hù)環(huán)境。 三、活動(dòng) 圍湖造田的利與弊 1、識(shí)湖泊灘地的地形優(yōu)勢(shì)，人們擇地而居，在那里開墾種植，歷史悠久。 2、介紹新中國(guó)成立后人們對(duì)糧食的需要造成了大規(guī)模的圍湖造田，以洞庭湖為例，出示洞庭湖面積變化歷史表。 3、學(xué)生展開分析討論： 湖面變化呈什么趨勢(shì)？（學(xué)生通過數(shù)據(jù)不難發(fā)現(xiàn)洞庭湖的湖面在不斷縮小的趨勢(shì)。）大規(guī)模圍湖造田會(huì)造成什么后果？（給學(xué)生講述xx年長(zhǎng)江中游夏季的大洪災(zāi)災(zāi)情及原因，提示學(xué)生利用已有的知識(shí)來分析可能造成的后果，如湖面變小對(duì)湖中生物的影響，對(duì)氣候的影響，對(duì)蓄水的影響等等，推進(jìn)學(xué)生的深入思考。） 4、全班交流。 5、匯報(bào)交流，提升認(rèn)識(shí)：人與自然要和諧相處的重要。 附送： 2019年(秋)六年級(jí)英語(yǔ)上冊(cè) Unit1 How can I g et there教學(xué)設(shè)計(jì)1 （新版）人教PEP 教學(xué)內(nèi)容: Unit 1 Part A Let’s learn ＆ make a map and talk 教學(xué)目標(biāo): 1、Can listen, read, write and say the words: science museum, post office, cinema, hospital, bookstore, library and can use “next to、near、behind, in front of ” to say where the place is. 2.
