市场上对任何年龄段的人来说最神秘的产品之一是荧光棒：一种塑料管，当折断时，产生大量明亮，色彩鲜艳的光，而不使用电力或大量产生热量。在这种情况下，化学发光反应也提供了一个令人兴奋的现象，通过它我们可以让学生参与科学和工程实践。这个实验室项目的开发既激发了学生对手头任务的兴趣，也让他们以比传统的“食谱”实验更真实的方式实践科学。在完成这个项目，学生将不仅获得影响化学发光反应速率的因素的理解，但也能够创建自己的程序，分析和解释他们的数据，并从他们的结果构建一个基于证据的论点。
One of the most mystifying products on the market for people at any age is the glow stick: a plastic tube that, when snapped, creates a flood of bright, brilliantly colored light without the use of electricity or significant production of heat. In this case, the chemiluminescence reaction also provides an exciting phenomenon through which we can engage students in the Scientific and Engineering Practices. This laboratory project has been developed both to pique students' interest about the task at hand and to have them practice science in a more authentic way than a traditional "cookbook" experiment. In completing this project, students will not only gain an understanding of the factors affecting the rate of the chemiluminescence reaction but also be able to create their own procedures, analyze and interpret their data, and construct an evidence-based argument from their results.
