能源是一个跨越科学学科的复杂概念。结合化学键和化学反应的能量方法比传统的主要关注机械能的入门物理方法更能满足生命科学学生的需求。我们提出了一个课程序列，或线程，旨在建立学生的化学能的理解，在介绍物理课程的生命科学。这条线旨在连接物理，生物和化学的能量思想。我们描述了能源概念之间的连接，我们开发建立跨学科的连贯性，并提出了一些课程材料和学生数据，说明我们的方法的例子。
Energy is a complex idea that cuts across scientific disciplines. An approach to energy that incorporates chemical bonds and chemical reactions is better equipped to meet the needs of life sciences students than a traditional introductory physics approach that focuses primarily on mechanical energy. We present a curricular sequence, or thread, designed to build up students' understanding of chemical energy in an introductory physics course for the life sciences. This thread is designed to connect ideas about energy from physics, biology, and chemistry. We describe the kinds of connections among energy concepts that we develop to build interdisciplinary coherence and present some examples of curricular materials and student data that illustrate our approach.
