1、名师精编优秀教案探究串、并联电路的电流规律教学目标1、知识与技能探究串、并联电路中电流的规律;训练连接电路和使用电流表的技能。2、过程与方法切身体验科学探究全过程,领会科学研究的方法。3、情感态度与价值观培养严谨的科学态度与协作精神。重点难点突破重点:体验科学探究全过程,领会科学研究的方法。难点:学生自主设计探究方案和学生实验操作。教学突破:在这一节的两个探究活动中,要将探究活动的程序性知识正面的交给学生,而且要学生体验科学探究,学习科学探究的方法。本课中重在过程而不在结论,关键是要求学生认真经历探究活动的各个环节,写出报告。教学媒体电源、小灯泡(2.5V、3.8V)、开关、导线、电流表。教学
2、过程一、导入新课学生竞赛:根据实验桌上给出的电源,开关,灯泡2.5V 一个,3.8V两个,导线若干等实验器材,把两灯连接成串联电路。要求灯亮后举手示意,在学案上画出相应电路图,并标出电流方向。名师精编优秀教案(学生实验时,教师适时的评价学生的表现,关注连接电路有困难的学生。)学生画完电路图后,引导学生再次闭合开关,观察灯的亮度并由看到的现象提出自己的疑问或想法。挑选出最典型的问题:串联电路中各处电流大小有怎样的关系?二、进行新课1、探究串联电路的电流规律(1)提出猜想由于学生所选灯泡规格不同,那么亮度也就不同。学生通过观察发现,两个灯泡的亮度可能一样,也可能是靠近电源正极的灯泡亮,也可能是靠近
3、电源负极的灯泡亮。适时的引导学生猜想:你们认为串联电路中通过各电路元件的电流有什么关系呢?说说你这样猜想的依据是什么?把你的猜想和依据写在学案上,全班交流。学生交流,甚至争论,发言提出自己的猜想。猜想 1:串联电路中电流处处相等。因为串联电路中灯泡一样亮。猜想 2:串联电路中电流从正极出发越来越小。电流每经过一个灯泡,就消耗一部分电流,回到负极就小了。猜想 3:电流有时大有时小,灯泡亮,它需要的电流大,灯泡暗,需要的电流小。猜想 4:串联电路电流靠近电源正极的比较大,因为靠近电源正极的灯泡比较亮。文档编码:CF2T10B9R3A9 HC10W10C6Z7A4 ZQ8K2S6Q9W1文档编码:C

11、收集数据。学生实验过程中,教师巡视辅导,同时提示学生:测哪一点的电流就把哪一条导线断开,串入电流表。串入电流表时,注意电流表正进负出。通过试触确定量程。一位同学做完实验后,另一同学重新选择灯泡再做一遍。对实验的数据处理:学生实验后不要求学生设计实验表格,实验数据直接记录在实验电路图上所选点的旁边。(4)分析论证,得出结论。把各小组实验中收集的数据展示,进行分析。如:文档编码:CF2T10B9R3A9 HC10W10C6Z7A4 ZQ8K2S6Q9W1文档编码:CF2T10B9R3A9 HC10W10C6Z7A4 ZQ8K2S6Q9W1文档编码:CF2T10B9R3A9 HC10W10C6Z7A
