一、通过有趣的实验来创设情境学生在最初接触《化学》这门课程时,是一种望而生畏的恐惧心理,如何让学生感受到《化学》是一门有趣而又与生活实际紧密相联的科学是化学教师上好第一节化学课的关键,因此,在学习“开启化学之门”时,教师可以设计这样几个有趣演示实验,如“加热碳酸氢铵”、“雨落花开绿叶出”、“空瓶生烟”等奇景,激发学生进一步探究学习的兴趣和欲望,使他们感受 1. Creating Situations Through Fun Experiments Students were a daunting fear when they first came into contact with chemistry. How to make students feel “chemistry” is a fun and closely linked reality. Science is the key to chemistry teachers’ good chemistry lessons in the first quarter, so teachers can design such interesting experiments as “heating ammonium bicarbonate,” “learning chemistry, Rain falling green leaves out ”, “ empty bottles of smoke ”and other wonders, to stimulate students to further explore the interest and desire to learn to make them feel
