在没有传统实验室空间的情况下教授化学是一个持续的挑战，由于SARS-CoV-2大流行，这一挑战变得尤为重要。虽然有几个远程学习选项涵盖一般化学概念（包括基于厨房的实验，在线模块和虚拟现实），但很少有选项提供动手学习合成聚合物材料化学的机会。在这里，我们提供远程学习模块，使用家用粘合剂作为实验室外教授聚合物化学的平台。这些模块是专为学生谁采取了至少一个学期的有机化学，并有不同的动手时间的承诺，从2到10总小时不等。涵盖的概念包括聚合物合成，分子间的相互作用，热机械性能，结构功能关系和分子设计。这些模块中描述的实验也让学生有机会练习与研究相关的技能，例如搜索主要文献来源，制作测试样本，解释意外的实验结果，以及修改实验程序以改进方法。最终，这些模块为教育工作者提供了在实验室之外教授实验化学的额外工具。
Teaching chemistry without access to a traditional laboratory space is an ongoing challenge that has become especially relevant because of the SARS-CoV-2 pandemic. While several remote learning options exist for covering general chemistry concepts (including kitchen-based experiments, online modules, and virtual reality), few options provide opportunities for hands-on learning about the chemistry of synthetic polymer materials. Here, we offer remote learning modules that use household adhesives as a platform for teaching polymer chemistry outside of the laboratory. These modules are designed for students who have taken at least one semester of organic chemistry and have varied hands-on time commitments, ranging from 2 to 10 total hours each. Concepts covered include polymer synthesis, intermolecular interactions, thermomechanical properties, structure–function relationships, and molecular design. The experiments described in these modules also give students a chance to practice research-relevant skills such as searching for primary literature sources, fabricating test samples, explaining unexpected experimental results, and revising experimental procedures to improve methodologies. Ultimately, these modules provide educators with an additional tool for teaching experimental chemistry outside of the laboratory.
