Mr. Dai Anbang famous chemistry has said that experiments, no matter how to emphasize too much.But in the ninth grade chemistry teaching, some teachers and teachers to weaken the experimental teaching, do more or less experiment , Leading students to remember the experimental phenomenon, experimental back, experimental skills are not properly training, affecting the formation of academic quality, but also affect students learning chemistry
