摘　　要：以“我是火箭推进剂设计师”为主题,以“如何使火箭飞起来”作为驱动性问题,在“能量”大概念的统领下,开展跨学科实践活动。通过“探寻火箭升空的奥秘、火箭推进剂的选择与利用、氢能源的认识和选择”等3个核心活动,建构“从物质变化、能量变化、反应条件、反应现象、反应类型、元素守恒等多个角度认识化学变化”的认知模型,从化学视角对简单的跨学科问题进行探讨,从而体会合理利用物质、调控化学反应的重要性。This study takes“I am rocket propellant designer”as the theme and“how to make rockets fly”as the driving problem.Under the command of the big idea of“energy”,the interdisciplinary practice is carried out.Through the three core activities of“exploring the mystery of rocket launch,the selection and utilization of rocket propellant,and the understanding and selection of hydrogen energy”,the cognitive model of“understanding chemical changes from the perspectives of material change,energy change,reaction conditions,reaction phenomena,reaction types and conservation of elements”is constructed.And the simple interdisciplinary problems are discussed from the perspective of chemistry to understand the importance of rational utilization of substances and regulation of chemical reactions.

关 键 词：跨学科实践活动 能量 大概念 火箭推进剂 设计师
