This project addreses a current dilemma in science education. The subject matter of physical chemistry is somewhat abstract. Laboratory experiments demonstrating the results of models are essential to making lessons more concrete. However, contemporary physical chemistry experiments, featuring the development of a molecular-level picture of interactions, often use very expensive equipment. Faced with fiscal constraints, many institutions have been reluctant to invest in equipment. The result is that physical chemistry laboratory courses tend not to reflect contemporary practices. The project is developing a series of laboratory exercises focusing on molecular-level processes in two areas; materials surface chemistry and biochemistry. A series of open-ended, inquiry-based laboratory exercises are enabling students to develop an image of consequences of models such as particle-in-the-box, spherical waves (the hydrogen atom), and bonding interactions. *

这个项目解决了当前科学教育中的一个困境。物理化学的主题有点抽象。展示模型结果的实验室实验对于使课程更加具体至关重要。然而，当代的物理化学实验，以发展分子水平的相互作用图为特色，通常使用非常昂贵的设备。面对财政限制，许多机构一直不愿投资于设备。其结果是，物理化学实验室课程往往不能反映当代的实践。该项目正在开发一系列实验室练习，重点放在两个领域的分子水平过程：材料表面化学和生物化学。一系列开放式的、以探究为基础的实验室练习使学生能够对箱中粒子、球面波(氢原子)和成键相互作用等模型的后果形成一幅图景。*
