一般来说，实验室实验主要集中在传统的化学学科上。虽然这种方法允许学生学习和探索特定领域的基本概念，但它并不总是鼓励学生探索跨学科的科学。通常很少观察到知识从一个领域转移到另一个领域，因为学生们被一步步地指导如何在很少参与或解决问题的情况下完成他们的任务。在这里，我们提供了一个针对个人探索和发展的实时研究实验室实验的例子，其科学目标是发现廉价、稳定的氧化物半导体，它可以有效地将水光电解成可用的燃料氢气。学生们创造独特的金属氧化物半导体组合，使用购买的扫描站扫描样品的光活动，并将他们的发现报告给合作数据库。该项目的一个显著特点是能够在不同的教育水平上实施，并相应地涵盖材料的广度和深度。目前，工具包正被用于中学课堂、本科生机构或作为外展活动。该项目为来自不同学科的学生和科学家提供了在与清洁能源和全球能源危机有关的研究方面进行合作的机会。
In general, laboratory experiments focus on traditional chemical disciplines. While this approach allows students the ability to learn and explore fundamental concepts in a specific area, it does not always encourage students to explore interdisciplinary science. Often little transfer of knowledge from one area to another is observed, as students are given step-by-step instructions on how to complete their task with little involvement or problem solving. Herein, we provide an example of a real-time research laboratory experiment that is aimed at individual’s exploration and development, with the scientific goal of discovering inexpensive, stable oxide semiconductors that can efficiently photoelectrolyze water to a useable fuel, hydrogen. Students create unique metal oxide semiconductors combinations, scan the samples for photoactivity using a purchased scan station, and report their findings to a collaborative database. A distinctive feature of the project is its ability to be implemented in a variety of educational levels with a breadth and depth of material covered accordingly. Currently, kits are being used in secondary education classrooms, at undergraduate institutions, or as outreach activities. The project provides students and scientists from different disciplines the opportunity to collaborate in research pertaining to clean energy and the global energy crisis.
