双减背景下基于生活情境的科普实验--以小苏打和白醋的反应为例

Experimental Research on Science Popularization Based on Life Situations in the Context of Double Reduction——Taking the Reaction Between Baking Soda and White Vinegar as an Example

“双减”背景下教师需要注重以学生为本设计多样化的活动,在拓宽学生视野的同时促进学生全面发展。基于生活情景引发学生思考:“小苏打为什么可以发面蒸馒头?”通过小苏打和白醋的反应探究发面的适宜条件。设计科普实验教学,让学生在科普实验中体会到科学知识的趣味性,从而乐学、好学,达到培养学生综合素质的目的。

Teachers in the context of“double reduction”need to focus on student-oriented design of diversified activities to broaden the horizons of students while promoting the overall development of students.Based on life situations,students are prompted to think:“Why can baking soda make noodles and steam buns?”Through the reaction of baking soda and white vinegar to explore the appropriate conditions,it can be designed science experiment teaching,so that students can experience the fun of scientific knowledge in science experiments,so that they can enjoy learning,learning,to achieve the purpose of cultivating the comprehensive quality of students.
