摘　　要：冰在淡水还是盐水中熔化得更快,可以与温盐环流的驱动机理、新仙女木期全球变冷的成因猜测结合,形成一个物理学科主导的跨学科研究性学习项目.主要以师生对话的形式,介绍课题实施过程,说明每个环节的设计要点,供相关学校和教师参考使用.Will ice melt faster in fresh water or in salt water is related to the driving mechanism of thermohaline circulation and the cause of global cooling during the Younger Dryas.It can be summarized to form an interdisciplinary research study project.In this paper,the implementation process of the project was introduced in the form of teacher-student dialogue,and the design points of each task link were explained for reference by relevant schools and teachers.

关 键 词：研究性学习 对流换热 温盐环流 新仙女木期
