This project is developing hands-on experiments and explanatory material that train students in analyzing multiple length and time scales in transport phenomena based on ideas of transport and hydrodynamic instabilities. The experiments mostly comprise of simple tabletop demonstrations and have both flexibility and variability. The material is being made available in a WEBCT format and explains experimental phenomena using picture arguments, scaling arguments and mathematical analysis and is fortified with animations and applications to engineering, everyday experience and natural phenomena. Each experiment and accompanying material is a stand-alone and can be exported in modules or in groups of modules to classes in heat, mass and momentum transport. These experiments and video clips are being constructed so that they are of use to curricula in chemical, mechanical, materials, and biomedical engineering, and engineering physics.The beneficiaries of the proposed prototype are undergraduate students and faculty alike. The experiments are particularly helpful for the visual intuitive student whose appreciation does not lie in the mathematical model, rather in the art form and in the physics underlying the phenomena. Yet, they also benefits the analytical deductive student and stir up creativity in both types of students. The professor gains because the hands-on experiments are expected to liven up the lectures and sustain the interest of the student. The prototypes are being be tested in a classroom setting and evaluations are being conducted both during the formative and execution phases of the project.Intellectual Merit of the Proposal: The proposed activity is based on over twenty years of research experience of the PI. The students are learning to think creatively and view transport phenomena as more than a mathematical subject to be tolerated. The intellectual merit lies in the fact that the affected audience actually learns to become intellectuals instead of number-crunching technicians.Broader Impacts of the Proposal: The proposed study encourages the participation of undergraduate students and graduate students in the development of the educational materials. As a result, students are being encouraged to participate in the education process and consider teaching and research as a career. In this Proof of Concept phase, the results of the project are being tried at the University of Florida. The PI is also sending materials to the University of Idaho where one of their faculty members is trying the materials in a course on fluid flow and transport. Both universities have substantial numbers of women and minority students. Dissemination is via the electronic media and major conferences.

该项目正在开发动手实验和解释性材料，这些实验和解释性材料培训学生根据运输和流体动力学不稳定性的思想分析运输现象中的多长度和时间尺度。实验主要包括简单的桌面演示，具有灵活性和可变性。该材料以WebCT格式提供，并使用图片论证，扩展参数和数学分析来解释实验现象，并通过动画和应用程序和应用程序，对工程，日常经验和自然现象进行了强化。每种实验和伴随的材料都是独立的，可以在模块或模块组中导出到热，质量和动量运输的类中。这些实验和视频剪辑正在构建，以便它们用于化学，机械，材料和生物医学工程以及工程物理学的课程。拟议的原型的受益者是本科生和教师。这些实验对视觉直觉学生特别有用，他们的欣赏不在于数学模型，而不是艺术形式和现象的物理学中。然而，它们也受益于分析性演绎学生，并激发了两种学生的创造力。教授获得了，因为预计动手实验会使讲座的生命并维持学生的兴趣。原型在课堂环境中进行了测试，并且在项目的形成阶段和执行阶段进行评估。该提案的智能优点：拟议活动基于PI的20多年的研究经验。学生正在学习创造性的思考，并将运输现象视为要容忍的数学主题。知识分子的优点在于，受影响的受众实际上学会了成为知识分子而不是数字化技术人员。提案的影响力的影响：拟议的研究鼓励本科生和研究生参与教育材料的发展。结果，鼓励学生参加教育过程，并将教学和研究视为职业。在这个概念验证阶段，该项目的结果正在佛罗里达大学尝试。 PI还向爱达荷大学发送材料，其中一位教职员工正在尝试有关流体流和运输的课程中的材料。两所大学都有大量妇女和少数族裔学生。传播是通过电子媒体和主要会议。
