Biology is a highly practical natural science, biological experiment teaching is an important means of training students ability and creativity. The current biological experiment efficiency is generally not high, the effect is poor, the reason, or due to equipment, drugs and other experimental conditions, or some demonstration design of the experiment there is a natural deficiency, leading to the experimental phenomenon is not satisfactory, it is difficult to achieve biological Experimental teaching objectives. Therefore, biology teachers must teach students according to their aptitude, according to local conditions, with the actual into the nature, into the students
