Interdisciplinary (99) Portable, easily used instruments to conduct experiments focusing on electromagnetic radiation and its effects on the natural world are being purchased for use in two freshmen chemistry courses and a sophomore environmental science course. Several existing experiments are being adapted and others developed to determine: 1) the temporal solar intensity and wavelength profiles incident on earth's surface, 2) the influence of light irradiance and visible wavelengths on terrestrial plant photosynthesis, and 3) the thermodynamic and electrochemistry principles behind solar-based hydrogen-oxygen fuel cell technology. All experimental work is field-based and is of an open-ended, investigative character as opposed to verification type laboratory work. Individual experiments are performed over a several weeks in contrast to isolated, single event ones frequently encountered in introductory courses. Arizona Western College is a two-year school designated by the U.S. Department of Education as a Hispanic Serving Institution. Over fifty percent of the student body are Hispanics and they account for seventy-five percent of the minority enrollment. It is expected that the new laboratories will impact 175 students annually.

我们正在购买便携式、易于使用的仪器来进行电磁辐射及其对自然界的影响的实验，这些仪器将用于两门大一的化学课程和一门大二的环境科学课程。目前正在调整和发展若干现有实验，以确定：1)入射到地球表面的太阳时间强度和波长分布；2)光辐照度和可见光波长对陆生植物光合作用的影响；3)基于太阳能的氢-氧燃料电池技术背后的热力学和电化学原理。所有的实验工作都是基于现场的，是开放式的，调查性质的，而不是验证型的实验室工作。单独的实验在几周内完成，而不是在入门课程中经常遇到的孤立的、单一的事件。亚利桑那西部学院是一所两年制学校，由美国教育部指定为西班牙裔服务机构。超过50%的学生是西班牙裔，他们占少数族裔入学人数的75%。预计新实验室每年将影响175名学生。
