地球的形状与大小教案(新版)商务星球版.pdf

学习必备欢迎下载地球的形状与大小【教学目标】1通过对中外史料的学习，了解人类对地球形状的探索历程，能够描述地球的形状。2学会运用平均半径、赤道周长和表面积描述地球的大小。（重点）3使学生领悟到人类对地球的认识，是一个孜孜不倦的求索、深化的过程，引导学生领悟追求真理的精神，促进其求真务实科学态度的形成。（难点）【教学模式】问题导学。【教学方法】启发示教学法、模拟体验法、小组讨论法。【教具准备】多媒体、橡皮泥。【教学过程】教学环节教师活动学生活动设计意图创设情境导入新课教师朗诵一首有关地球的诗歌：在浩瀚无限的宇宙/有一个美丽的星球/它是人类的家园/它是太阳和月亮的朋友/岁月匆匆/往事悠悠/地球已有亿万年的高寿/它默默地/看着人类诞生/看着人类成长/看着人类在探索地球形状的历史中踽踽行走 人类自诞生以来，就从未停止过对地球的好奇与探索。地球究竟是什么形状？这一问题千百年来一直困扰着人类。同学们知道人类对地球形状认识的探索历程吗？引导学生思考：人类认识地球形状的历史过程是怎样的呢？通 过 倾 听有 关 地 球的诗歌，激发 学 生 对人 类 探 索地 球 形 状的 好 奇 心与求知欲。观察与思考 地球的形状多媒体展示人类探索地球形状不同历史时期的四幅图片，让学生观察并思考前人曾得出的结论。学 生自主学习观察图1，对于地球形状的认识，我 国 古 代 的 观 点是。通 过 一 系列 的 观 察与 思 考 活动，培养学生 的 观 察能 力 和 读图能力。学习必备欢迎下载图 1 图 2 图 3 图 4 观察图2，古希腊学者亚里士多德，根据月食的景象推测，得出地球的形状是。观察图 3，1519 年 1521 年，麦哲伦船队首次环航地球，环球 航 海 实 证 了 地 球 的 形 状是。观察图4，通过近代人类拍摄的地球卫星照片，人类确证地球的形状是。阅读与探索让学生阅读“你们第一个拥抱了地球”文图资料，并思考回答下列问题？1、从人类认识地球形状的过程中，你感悟到了什么？2、假 如你要驾船做一次远洋航行，除了必备的生活用品外，还需要携带哪些工具？3、当观 察远方驶来的海船时，为什么先是看见桅杆，最后才看见船身？根据探索的问题，小组内交流与讨论，并引导学生思考：在日常生活中，还有哪些现象能够说明地球是个球体？古诗词中所描写的“欲穷千里目，更上一层楼”反映了什么地理事实？初 步 培 养学 生 对 地理 探 索 的兴趣，追求科 学 真 理的精神，并认 识 到 地理 知 识 就在 我 们 身边，学习地理知识，能够 增 强 自己 的 生 活和 生 存

地球的大小出示地球的大小示意图通过以下形象的说法让学生体会到地球的“巨大”：假如我们乘坐每小时飞行800 千米的飞机，沿着赤道绕地球飞行一周，得用 50个小时。地球的表面积是5.1亿平方千米，这个面积相当于53 个我国领土（960 万平方千米）那么大。学生借助教师编写的口诀来理解识记。地球是个大球体“赤径”长（六三）七八，极径短二一平均半径是（六三）七一坐地（赤道）日行八万里（4 万千米）表面（积）就有好几亿（平方千米）七分海洋，三分陆地陆海总共五点一运用事例比较和口诀的方法，帮助学生理解与识记地球的大小。思考与体验1、比较赤道半径、极半径，你对地球形状有什么新的发现？（地球是一个两极赤道的不规则球体。）2、要求学生绘制地球的大小示意图。3、用橡皮 泥自制一个地球模型。通过思考与体验，加深对所学知识的理解与记忆。拓展与延深在自然科学研究领域中,广泛采用近似方法。与绝对真理相比较,一切具体的认识以及获得该认识的方法,都是近似的。所以，我们通常把地球看作一个正球体。下节课，我们还要接触到科学研究的另一种方法：模型法。学生阅读“地球的形状”文字资料，说说科学研究的方法。让学生理解科学研究的基本方法，比如：近似法、模型法，同时也为学习地球仪做好 方 法 准备。文档编码:CE10W9P6R1U9 HB2J6X7I8A6 ZF10J4T9F1L10文档编码:CE10W9P6R1U9 HB2J6X7I8A6 ZF10J4T9F1L10文档编码:CE10W9P6R1U9 HB2J6X7I8A6 ZF10J4T9F1L10文档编码:CE10W9P6R1U9 HB2J6X7I8A6 ZF10J4T9F1L10文档编码:CE10W9P6R1U9
