Flying kites Kites have quite a long history. The earliest kites were made ofwood, instead of paper. Nowadays, the three most famous kites are the Beijingkite, Tianjin kite, and Weifang kite. And they are quite different from eachother. For example, the swallow-shaped kite is a well-known Beijing style.

1、诗作引雁:同学们,有一种鸟,常常是文人墨客吟诗赋词入题的最爱,这种鸟很容易牵动人们的羁旅情思,令人睹鸟伤情、托鸟寄怀,从而留下许多浪漫、感人、富有诗意的作品,这种鸟就是秋寒南征、春暖北归的大雁。现在就让我们在这优美而略带忧伤情感的音乐中,一起回忆我们学过的有关大雁的优美诗句。学生汇报,教师展示。 征蓬出汉塞,归雁入胡天。——王维《使至塞上》 长风万里送秋雁,对此可以酣高楼。——李白《宣州谢眺楼饯别校书叔云》 乡书何处达?归雁洛阳边。——王湾《次北固山下》(思乡情怀) 塞下秋来风景异,衡阳雁去无留意。——范仲淹《渔家傲》 云中谁寄锦书来,雁字回时,月满西楼。—— 李清照《一剪梅》 2、引入课题:由此可见,中国人眼中的大雁是这样的富有诗情画意,是这样的充满浪漫色彩。那你想不想知道,外国人心中的大雁是怎样的吗?今天,就让我们跟随美国生态学家利奥波德一同走进大雁的世界。请大家打开课本111页,第十四课,大雁归来(出示课题和作者)
你能不能用你的本领把这山村美景表达出来呢? 老师请画画的小朋友在这花丛里,写诗的在小山坡上……….. 四、完美结课: 小朋友玩的高兴吗?好我们一起回家啦!(播放《郊游》)。 教学反思: 启发学生“你都想到了什么?”从而让学生展开丰富的想象,经过教师的简单小结使学生了解了牧童的生活和放牧时的心情,为学唱歌曲《放牛歌》做情感铺垫。 接下来的“体验理解”环节还是以激发学生兴趣为主,从猜小牧童的“宝贝”(笛子)模仿小牧童吹笛子的动作,到学吹笛子的有节奏的嘀嘀声XXXXXX,到有节奏的模仿小黄牛的叫声X-,我都是在让学生从间奏入手的,目的:一是引导学生会听音乐,能听出哪是间奏;二是让学生充分感受歌曲的旋律,熟悉歌曲;三是培养学生[此文转于斐斐课件园 FFKJ.Net]节奏感,知道笛声和小黄牛的叫声表示的节奏是什么,对两个声部的节奏训练进行一次渗透和尝试。
三、作出速度-时间图像(v-t图像)1、确定运动规律最好办法是作v-t图像,这样能更好地显现物体的运动规律。2、x y x1 x2 y2 y1 0讨论如何在本次实验中描点、连线。(以时间t为横轴,速度v为纵轴,建立坐标系,选择合适的标度,把刚才所填表格中的各点在速度-时间坐标系中描出。注意观察和思考你所描画的这些点的分布规律,你会发现这些点大致落在同一条直线上,所以不能用折线连接,而用一根直线连接,还要注意连线两侧的点数要大致相同。)3、若出现了个别明显偏离绝大部分点所在直线的点,该如何处理?(对于个别明显偏离绝大部分点所在直线的点,我们可以认为是测量误差过大、是测量中出现差错所致,将它视为无效点,但是在图像当中仍应该保留,因为我们要尊重实验事实,这毕竟是我们的第一手资料,是原始数据。)4、怎样根据所画的v-t图像求加速度?(从所画的图像中取两个点,找到它们的纵、横坐标(t1,v1)、(t2,v2),然后代入公式,求得加速度,也就是直线的斜率。在平面直角坐标系中,直线的斜率
