物理教学中有不少教师不愿意在课堂上做演示实验.究其原因,主要是因为有些实验的安装、制作过于繁琐,且不一定能达到理想的实验效果,甚至还不如在黑板上讲实验或者播放视频的效果好.此时,如果利用方便易得的原材料制作自制教具,往往能化繁为简,并取得预期效果.矿泉水瓶是中学阶段物理自制教具中经常出现的主角.我们对矿泉水瓶自制教具进行了二次改良,原实验在
There are many teachers in physics teaching are not willing to do demonstration experiments in the classroom.The reason is mainly because some experiments installation, production is too complicated, and may not be able to achieve the desired effect of the experiment, not even on the blackboard to talk about the experiment Or play the video good effect at this time, if the use of easy-to-use raw materials made of self-made teaching aids, often can simplify and achieve the desired results.Nature water bottle is a middle school physics self-made teaching aids often appear in the protagonist of our mineral springs Aquarius made a second improvement in teaching aids, the original experiment in
