虽然实验设计在许多领域和行业都很重要，但大多数本科生在标准的实验课程中没有接触到这一点。这项工作描述了一个学生设计的，为期数周，具有环境应用的灵活的化学实验，包括析因实验设计和方差统计分析分析。通过实验，学生们试图更好地了解活性碳在一系列因素下对染料的吸附，这些因素可能包括染料类型、碳类型、pH、盐度、硬度和接触时间，每个因素都在多个水平上。该实验很容易适应一系列的学生入学，只使用普通的实验室玻璃器皿和任何可见的分光计。
Although experimental design is important in many fields and industries, most undergraduate students do not get exposure to this in a standard lab curriculum. This work describes a student-designed, multiple-week, flexible chemistry experiment with environmental applications that include factorial experimental design and analysis of variance statistical analysis. Through the experiment, students attempt to gain a better understanding of activated carbon adsorption of dyes under a set of factors, which could include type of dye, type of carbon, pH, salinity, hardness, and time of contact, each at multiple levels. The experiment is easily adaptable for a range of student enrollments and uses only common laboratory glassware and any visible spectrometer.
