物理课程标准提倡师生利用身边随手可得的生活用品自制教具进行实验.很多物理实验会用到漏斗或漏斗型教具,在实际教学中可以利用饮料瓶来自制出轻便实用且有个性化的漏斗(下文统称“自制塑料漏斗”).如图1所示,“自制塑料漏斗”的方法比较简单:先用剪刀剪出塑料瓶瓶口圆锥部分,再用电烙铁在饮料瓶瓶盖上烫出一个小孔后插入一截导管即可.可选用的导管有透明塑料笔杆(或笔杆头)、笔芯、注射器针筒或针头等,具体可根据实验要 Physics curriculum standards to promote teachers and students to use readily available daily necessities of self-made teaching aids experiment.Many physical experiments will use funnel or funnel-type teaching aids, in the actual teaching can drink bottles made from light practical and personalized funnel (Hereinafter collectively referred to as “self-made plastic funnel”.) As shown in Figure 1, “home-made plastic funnel ” method is relatively simple: first scissors cut plastic bottle bottle conical part, and then iron in the beverage bottle Cover a small hole after the hot plug into a catheter can be optional catheter with a transparent plastic pen (or pen head), refills, syringe syringes or needles, according to the specific experiment
