生活中到处都有物理现象,物理知识来源于生活,最终又服务于社会．在现实生活中,许多人饮用矿泉水后,随手乱扔矿泉水瓶,不仅污染环境,还可能引发森林火灾．我们可以收集旧矿泉水瓶,变“废”为“宝”,还可以利用矿泉水瓶进行许多物理实验．这样不仅解决了广大农村学校实验器材紧缺的问题,还可以让同学们自己动手做实验,感受物理知识 Everywhere in life there are physical phenomena, physical knowledge comes from life, and finally serves society. In real life, many people throw mineral water in hand after drinking mineral water, not only polluting the environment, but also causing forest fires. We can collect old mineral water bottles, change “waste” to “treasure,” and use mineral water bottles for many physical experiments. This not only solves the problem of shortage of experimental equipment in rural schools, but also allows students to experiment and experience physical knowledge.
