The continuous new curriculum reform has given new meaning to education, and it has put forward higher requirements for the teaching of biological laboratories. Students with strong hands-on ability and keen in thinking will be more and more favored by the future society. On September 8, Fengtai District High School Biology Teacher Experimental Skills Training Event was held in Beijing No. 18 Middle School. Practice is the only criterion for testing truth. As a highly applied biology department, practice has become an indispensable part of reality teaching. Based on this, the construction of the laboratory has become a focus of attention.
