小学科学是一门综合性课程,能够最有效地综合自然科学领域和技术领域中最基础的知识和技能,而探究是科学课最为重要的学习方式。因此,科学课必须重视实验教学。通过实验教学,可以激发学生的求知欲,培养学生多方面的实验能力,从而提高学生的综合素质。那么,如何促进科学课中的实验教学呢?笔者从以下几方面进行了尝试。一、有特征的材料使实验效果更明显笔者下面以“雨的形成”为例进行说明。1.实验原理。水受热变成水蒸气,水蒸气遇冷变 Primary science is a comprehensive curriculum that best synthesizes the most basic knowledge and skills in science and technology, and inquiry is the most important form of learning in science. Therefore, science class must attach importance to experimental teaching. Through experimental teaching, you can stimulate students’ curiosity and develop students’ ability to experiment in many aspects so as to improve students’ overall quality. So, how to promote the experimental teaching in science class? The author attempts from the following aspects. First, the characteristics of the material so that the experimental effect is more obvious The author below to “rain formation ” as an example to illustrate. 1. Experimental principle. Water into steam by the heat, water vapor case of cold change
