For children who are in a critical period of growth and have weak discernment and judgment, managing school toys well is more effective than blocking them. Recently, the use of neutral pens to create "pen guns" has become increasingly popular among primary and secondary school students, and such "teaching videos" can often be seen on social media platforms. From playing with "pen knives" and raising "stinky water", to making "pen guns" and syringes... every once in a while, there are always different school toys that become the favorite of "child brothers" and "child sisters". However, some campus toys often cause accidents due to improper gameplay, and the hidden safety hazards among them have caused concern for many teachers and parents. Homemade toys are easy to obtain materials and easy to make, coupled with "teaching videos" disguised as "creative production" and "stationery modification" to guide and follow the trend, which to some extent stimulates children's curiosity. When these toys become social tools, safety warnings often lose their deterrent power - some parents and teachers say that even with repeated warnings of danger and explicit prohibitions, some children continue to secretly make them. Faced with an endless stream of campus toys, we should control them, but we cannot ban them all. For children who are in a critical period of growth and have weak discernment and judgment, managing school toys well is more effective than blocking them. Provide appropriate safety guidelines and clarify the boundary between creativity and danger. Minors lack sufficient rational understanding of new things and may not be aware of seemingly harmless toys, which can lead to personal injury and property damage due to improper operation. Parents and teachers need to do a good job in promoting safety, and under the premise of not being disappointed, they should make three rules with their children: for example, when waving a toy gun, do not aim the muzzle at yourself or others; After squeezing the plasticine, it is important to wash your hands properly to avoid accidentally ingesting borax... After clarifying the boundaries between what can and cannot be done, dangerous toys and gameplay naturally lose their market. On this basis, it may be worth trying to combine education with entertainment, using subject knowledge guidance to turn children's curiosity into a thirst for knowledge. Children who are interested in "pen guns" may explore the principles of mechanics. Taking this as an opportunity, they can design more specific practices in the classroom related to adjusting spring elasticity and optimizing firing angles. This will give children a stronger drive to learn knowledge. Children who are enthusiastic about raising "stinky water" may be interested in chemistry and biology experiments. If related content is widely discussed in and out of the classroom, it may be possible to achieve a transformation from dangerous games to teaching resources. Healthy and beneficial toys contribute to children's intellectual development and physical and mental growth. In extracurricular activities, install safety locks on toys and teach children safety lessons, allowing them to gain more positive energy while enjoying themselves. (New Society)
