物理课程中的许多概念都可以用平方反比定律来解释，引力、电场、光、声、辐射等点状源都服从平方反比定律。这个几何定律使我们有能力统一各级教育中各种认知学科的教育方法。 在过去的几年里，我们一直在使用从事实践活动，以帮助我们的学生，以了解自然的凝聚力，并从实验数据导出结论。批判性思维的发展也受到学生实验活动的刺激。教学生批判性地思考也许是我们作为科学教师所做的最重要和最困难的事情。本文介绍了三个活动，这是由学生执行。这些活动是关于电磁辐射的，主要目的是证实平方反比定律。我们使用了三个活动，分别为：“平方反比定律-光”，“光度计的构建”和“放射源”。这项工作的重要动机构成了以下问题：“是否有可能找到实验室活动，这些活动带来了统一和非零碎的物理现象描述，帮助学生批判性地思考？”。
Many concepts in the physics curricula can be explained by the inverse square law. Point-like sources of gravitational forces, electric fields, light, sound and radiation obey the inverse square law. This geometrical law gives the ability of unifying educational approach of various cognitive subjects in all the educational levels. During the last years we have been using engaging hands-on activities to help our students in order to understand the cohesion in Nature and to export conclusions from experimental data. The development of critical thinking is also stimulated by student‘s experimental activities. Teaching students to think critically is perhaps the most important and difficult thing we do as science teachers. In this paper three activities are described, which were executed by students. These activities are concerning the electromagnetic radiation and the main goal is to confirm the inverse square law. We used three activities entitled as: “Inverse square law-Light”, “Photometer construction” and “Radioactive source”.The significant motive for this work constituted the following question: “Is it possible to find lab activities which bring out unification and a non-piecemeal description of physical phenomena, helping students to think critically?”.
