Abstract

Students have several misconceptions about thermodynamics. However, an understanding of basic concepts in this branch of physics remains fundamental to explain thermal phenomena. The purpose of this activity was to extend students’ conceptual understanding of heat, temperature, energy, and thermal insulators and conductors. Two groups of students in grade seven created insulation boxes to keep sheep organs in a hypothermic state for the longest time possible. The activity incorporated connections to real life, autonomy, and scientific investigations to motivate the students. The data indicated that the activity was sufficiently challenging for the students and that they were able to apply their understanding of both the corresponding concepts and scientific and engineering practices.

摘要

学生们对热力学有几个误解。然而，理解这一物理学分支的基本概念仍然是解释热现象的基础。此活动的目的是扩展学生对热、温度、能量以及热绝缘体和导体的概念性理解。两组七年级的学生制作了保温箱，使绵羊器官尽可能长时间处于低温状态。该活动结合了与现实生活、自主性和科学调查的联系，以激励学生。数据表明，该活动对学生来说具有足够的挑战性，并且他们能够应用他们对相应概念以及科学和工程实践的理解。
