The learning innovation developed at the University of California Davis (UC Davis) includes an in-house built water table, relevant wing models, and educational material. The project intends to scale the innovation to high school, community college and university education. The hydraulic analogy is between water flow with a free surface and two-dimensional compressible gas flow. The concept of hydraulic analogy demonstrated in the water table can serve as a great analogy not only for airplane wings but also rocket nozzles, wind turbines and many other flow related phenomena. The experiment is based on a well-known analogy between waves in compressible two dimensional flow of air to the surface waves of a shallow water layer over a flat surface. The innovation will be used in the course to demonstrate to students the hydraulic analogy using inexpensive tools. The hypothesis of this project is that the water table is a useful invention to reinforce high school and community college education. The hypothesis will be tested by conducting 100 interviews with relevant and potential customers. Students who participate in active learning with hands-on experiments learn through self-discovery. This will attract students to engineering and science and provide lasting learning experiences. Systematically, they learn to change their presumptions about the phenomena in physics and discover the underlying concepts. This way of teaching will develop critical thinking among students and effectively engage them in classrooms. The team expects not only to use this tool broadly at UC Davis, but anticipates that other educational institutes will adopt this method.

加州大学戴维斯分校（UC Davis）开发的学习创新包括内部建造的地下水位，相关的机翼模型和教育材料。该项目打算将创新扩展到高中，社区学院和大学教育。液压类比是在自由表面和二维可压缩气流的水流之间。在地下水位中证明的液压类比的概念不仅可以作为飞机机翼，还可以作为火箭喷嘴，风力涡轮机和许多其他相关现象。该实验是基于可压缩的两维空气流向浅水层的表面波的波浪之间的众所周知的类比。该创新将在课程中使用，向学生展示使用廉价工具的液压类比。该项目的假设是地下水位是增强高中和社区大学教育的有用发明。该假设将通过对相关和潜在客户进行100次访谈来检验。通过动手实验参加积极学习的学生通过自我发现学习。这将吸引学生进入工程和科学，并提供持久的学习经验。从系统的角度来看，他们学会改变对物理现象的假设，并发现基本概念。这种教学方式将在学生之间发展批判性思维，并有效地参与课堂。团队期望不仅在加州大学戴维斯分校广泛使用此工具，还希望其他教育机构将采用这种方法。
