2019年(秋)六年級科學上冊 3.6《人類對地表變化的影響》教案 湘教版.doc

2019年(秋)六年級科學上冊 3.6人類對地表變化的影響教案 湘教版教學目標科學探究1、通過對圍湖造田的利弊分析，培養(yǎng)學生綜合分析的能力。2、繼續(xù)提高學生搜集資料的能力。情感態(tài)度與價值觀1、意識到人類對地表變化的影響有利有弊，提高對這一問題的關注度和敏感性。2、意識到人類必須遵循自然規(guī)律改變地表，才能實現(xiàn)人與自然的和諧相處。科學知識1、了解人類活動對地表改變的影響。2、了解圍湖造田的利弊。教學準備課前布置學生收集因人類活動造成地表改變、水土流失的典型事例。教學重點指導學生通過收集和整理資料、召開辯論會等方式來探究“人類活動隊地表的影響”的問題。教學難點人類那些改造地表的活動是對人類有利的，哪些是不利的教學內容一、教學導入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，請大家列舉人類的哪些活動在不斷改變著地表形態(tài)？2、學生回答。3、過渡：人類的活動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、指導學生閱讀教材指南車信箱提供的資料。2、組織學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：人類活動是一種特殊的外力作用。因為隨著工農業(yè)和科學技術飛速發(fā)展，人類活動的深度和廣度與日俱增。對地表形態(tài)的影響是十分可觀的。如我國勞動人民根據(jù)自然規(guī)律和社會需要，長期的經濟活動塑造了許多地表形態(tài)特征非常明顯的人工地貌梯田、桑基魚塘、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，由于長期過量開采地下水而產生地面沉降，上海市至1965年累計沉降達2.6米；有人統(tǒng)計至1965年，地球大陸面積的8%已為各類工程所覆蓋，xx年面積將擴大近一倍；還有在礦產開采、農業(yè)生產、軍事活動和其他工程建設中，創(chuàng)造出許多新的地貌形態(tài)。（人類活動對地表形態(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害的發(fā)生。）我們要合理利用和保護環(huán)境。三、活動圍湖造田的利與弊1、識湖泊灘地的地形優(yōu)勢，人們擇地而居，在那里開墾種植，歷史悠久。2、介紹新中國成立后人們對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、學生展開分析討論：湖面變化呈什么趨勢？（學生通過數(shù)據(jù)不難發(fā)現(xiàn)洞庭湖的湖面在不斷縮小的趨勢。）大規(guī)模圍湖造田會造成什么后果？（給學生講述xx年長江中游夏季的大洪災災情及原因，提示學生利用已有的知識來分析可能造成的后果，如湖面變小對湖中生物的影響，對氣候的影響，對蓄水的影響等等，推進學生的深入思考。）4、全班交流。5、匯報交流，提升認識：人與自然要和諧相處的重要。附送：2019年(秋)六年級英語上冊 Unit1 How can I get there教學設計1 （新版）人教PEP教學內容:Unit 1 Part A Lets learn make a map and talk教學目標: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.
