聚合物演示在科学、技术、工程和数学教育课程中变得越来越重要。这些演示不仅提供了向学生介绍聚合物的机会，而且还提供了一种途径，让学生了解聚合物对地球的影响。尽管聚合物展示具有教育价值和娱乐享受，但一些历史上常见的聚合物展示存在严重的健康和环境危害，应予以解决。这个观点描述了历史上常见的聚合物“粘液”和“愚蠢的腻子”示范的好处和后果，然后详细介绍了可以取代它们的替代品。最后，包括更健康和更安全的聚合物演示的方法部分，以及详细的协议。
Polymer demonstrations have become increasingly important within science, technology, engineering, and math education curricula. These demonstrations not only afford the opportunity to introduce students to polymers but also provide an avenue to educate students about the impact polymers have on the planet. Despite the educational value and recreational enjoyment polymer demonstrations can provide, there are serious health and environmental hazards associated with some of the historically common polymer demonstrations that should be addressed. This Perspective describes the benefits and consequences of the historically common polymer “slime” and “silly putty” demonstrations and then details alternatives that can replace them. Finally, a Methods section of healthier and safer polymer demonstrations with detailed protocols is included.
