A digital learning-teaching environment is introduced in which undergraduate students are challenged to connect the basic physical concepts of oscillation, buoyancy and data analysis via an authentic experiment. The damped oscillation of a cylindrical body swimming upright in water is measured via the MEMS acceleration sensor of a wireless MCU SensorTag. The data are recorded with the app phyphox on a smartphone or tablet. The theoretical oscillation period and the experimentally determined periods obtained via different data analysis roots are found to agree showing an excellent theory-experiment interplay. The proposed experiment is suited for the physics home lab e.g. under the current pandemic situation or for open university courses as well as for physics lab courses.

引入了数字化学习-教学环境，在该环境中，本科生通过真实的实验将振荡、浮力和数据分析的基本物理概念联系起来。通过无线 MCU SensorTag 的 MEMS 加速度传感器测量直立在水中的圆柱体的阻尼振荡。数据通过智能手机或平板电脑上的应用程序phyphox记录。发现理论振荡周期和通过不同数据分析根获得的实验确定周期一致，显示出极好的理论-实验相互作用。提议的实验适用于物理家庭实验室，例如在当前的大流行情况下或开放大学课程以及物理实验室课程。
