六年级纸火箭活动

担任科学课教师,杨老师始终感到不那么自然。在内心深处,她觉得自己是一名英语老师。在课上讲解比较深的科学概念时,她会显出些许犹豫。不过,每一次我为她的学生们设计出新的科学活动,她总是迫不及待地尝试。新年前的两个星期,六年级学生们完成了两次科学活动,其中一次就是制作纸火箭。
目标:制作出可以在空中停留3秒钟以上的纸火箭
材料:电脑纸,空的3L饮料瓶,一根管子
时间:3课时
六年级的学生们一直都很善于分组合作。在老师说明活动目标之后,学生们被要求首先进行10分钟的小组讨论,研究火箭如何飞行。为了获得电脑纸,每个小组都要拿出设计创意,包括火箭的外观,各部分的作用。象往常一样,有的小组梦想着复杂豪华的设计,有的则只画出棍子似的简单图纸。

第二个课时的中段,我们到室外进行了首次火箭试飞。有些组的火箭差不多离不开地面。也有几个可以飞行2秒以上。首次试飞后,学生们兴高采烈地返回教室,改进纸火箭。他们意识到臃肿的箭身会阻碍飞行。很多小组立即决定放弃先前的设计,着手制作结构紧凑的改进版。第二天试飞时,八个小组中有六个组采用了纤细的火箭箭身,小尾翼或者无尾翼。有一半模型可以达到3秒左右的飞行时间。下面是第一天试飞的视频。

在 %I:%M%p 添加 2009年1月5号wow, the paper rocket lesson looks fantastic, and sounds like it was very successful! i love how you guys constructed a propeller with a plastic coke bottle and pipe. it’s brilliant!
i hope that the kids as well as yang laoshi had fun building rockets. were you also able to show the kids clips from the launch of “shen zhou 7″ and zhaizhigang’s spacewalk?
it would be really great if you can teach this lesson again in the future. i think it would also be interesting to discuss with the students why real rockets don’t usually fall from the sky after it’s launched, and the role of thrust and gravity. there are also clips that illustrate the multiple steps of rocket launch. i wonder if the kids would find that enjoyable.
great job!

在 %I:%M%p 添加 2009年2月3号I really liked reading about your rocket making lesson and the pictures were really great. Your students look like they are having a blast. I found your site while looking for international blog site for my EDM 310 class. I am a student at the University of South Alabama located in Mobile, Alabama in the United States. I am studying to be an elementary school teacher. Our teacher’s name is Dr. John Strange. He has asked us to contact the site we blogged about and try to start a line of communication. I would really enjoy hearing back from you. My blog site is: http://currymedm310spring09.blogspot.com
I look forward to hearing from you.
