化学是一门以实验为基础的学科。高中化学课程标准(实验)指出要“通过化学实验为主的多种探究活动使学生体验科学研究的过程”。本文在该理念的指导下,结合人教版高中必修模块《化学1》的知识内容,以选修模块6《实验化学》为依据,设计了一则探究性学习的案例,并进行了相关的实验。一、设计研究课题——用鸡蛋壳制备半透膜1、研究目的及意义半透膜是对不同粒子的通过具有选择性的薄膜。它广泛
Chemistry is an experiment-based discipline. The high school chemistry curriculum standard (experiment) states that it is necessary to “enable students to experience the process of scientific research through a variety of inquiry-based chemistry experiments”. Under the guidance of this concept, based on the knowledge content of the compulsory module “Chemistry 1” in the PEP curriculum, this essay designs an inquiry learning case based on the elective module 6 “Experimental Chemistry” and conducts related experiments . First, the design and research project - Preparation of semi-permeable membrane with eggshell 1, the purpose and significance of research Semi-permeable membrane is the selective passage of different particles of the film. It is extensive
