核化学是一个具有重大社会意义的话题，在医学、能源和国家安全领域都有应用。尽管这一领域很重要，但在 K-12 和本科教育中却很少受到关注。覆盖率低的部分原因是缺乏合适的教育资源来说明核化学的关键概念。在这里，我们描述了 K-12 课堂的两项活动的开发，旨在帮助教师交流核化学的几个概念方面。第一个活动是名为“同位素拉米纸牌”的互动游戏，该游戏已通过康奈尔材料研究中心 (CCMR) 开发为借阅图书馆套件。该游戏让学生了解原子核的组成以及决定核放射性衰变稳定性的因素。第二项活动称为“辐射与放射性衰变”，专为讲师指导的外展研讨会或演示而设计。该活动给出了自发放射性和受激光致发光衰变的例子。我们在各个高中教室单独或一起进行了这些活动，并在学生会议上作为完整的研讨会进行了这些活动。从教师和学生那里获得的反馈表明，这些活动有助于促进对核化学几个关键概念的理解。
Nuclear chemistry is a topic of great societal importance with applications in the realms of medicine, energy, and national security. Despite its significance, this area receives little attention in both K–12 and undergraduate education. This poor coverage arises in part from the lack of suitable educational resources to illustrate key concepts of nuclear chemistry. Here, we describe the development of two activities for the K–12 classroom, which are designed to assist instructors in communicating several conceptual aspects of nuclear chemistry. The first of these activities is an interactive game, called Isotope Rummy, which has been developed as a Lending Library kit through the Cornell Center for Materials Research (CCMR). This game informs students on the composition of the nucleus and factors that determine nuclear stability with respect to radioactive decay. The second activity, called Radiative versus Radioactive Decay, is designed for instructor-led outreach workshops or demonstrations. This activity gives examples of spontaneous radioactive and stimulated photoluminescent decay. We have performed the activities separately and together in various high school classrooms and as a full workshop at a student conference. Feedback obtained from both teachers and students indicates that these activities are helpful for fostering an understanding of several key concepts in nuclear chemistry.
