化学是一门以实验为基础的自然科学,通过实验能使学生更直观、更立体地获得化学基础知识和基本技能。但受条件制约,有些学校设备滞后,使得有些实验无法顺利进行,而且有些实验具有危险性,从安全角度考虑,大多学校不做或少做这些实验,这些都直接影响了实验教学的开展和学生实践创新能力的培养。 Chemistry is an experiment-based natural science, through which students can acquire basic knowledge and basic skills of chemistry more intuitively and stereoscopically. However, due to conditions, some of the school equipment lags behind, making some experiments can not be carried out smoothly, and some experiments are dangerous. From a safety point of view, most of the schools do not do these experiments or less, which directly affect the development of experimental teaching and students Cultivation of Practical Innovation Ability.
