Abstract

Bacteria, viruses, and other invisible creatures are, in brief, microorganisms. Especially with the onset of the COVID-19 pandemic, the features of microorganisms, their density, and relevant precautions have grown in importance. Knowing the density of microorganisms at school will cause our cleaning habits to change. In this study, efforts were made to determine the density of microorganisms in a school with an inquiry-based model. In the activity, students were divided into groups and traced microorganisms in different environments of the school using blood agar, swabs, and gloves. At the end of the activity, it was observed that the students had learned about the properties and density of bacteria and the precautions to be taken. In the course of this research, a rubric was developed that can be used for students with the “predict, observe, explain” technique.

摘要

细菌、病毒和其他看不见的生物，简而言之，就是微生物。特别是随着 COVID-19 大流行的开始，微生物的特征、密度和相关预防措施变得越来越重要。了解学校微生物的密度会导致我们的清洁习惯发生改变。在这项研究中，我们努力使用基于探究的模型来确定学校中微生物的密度。在活动中，学生们被分成小组，使用血琼脂、拭子和手套追踪学校不同环境中的微生物。在活动结束时，观察到学生们已经了解了细菌的特性和密度以及需要采取的预防措施。在这项研究过程中，开发了一个量规，可用于具有“预测、观察、
