Preparing for the high school entrance examination with vigorous military tactics, standardizing operations, and practicing real skills

In order to prepare for the 2026 middle school entrance examination for physics, chemistry, and student experimental operations, further strengthen students' experimental foundation, and enhance their ability to operate in a standardized and scientific manner, Nanchong No.11 Middle School recently organized a special experimental operation exercise for all third grade students.

Before the drill, the school attached great importance to and made careful arrangements. The teachers of the physics, chemistry, and biology teaching and research group compared the scoring rules of the middle school entrance examination, carefully sorted out the experimental test points, and optimized the operation process; The school conducts comprehensive inspections and supplements of laboratory equipment and reagents in physics, chemistry, and biology to ensure the safe, orderly, and efficient conduct of exercises.

At the drill site, students strictly followed the experimental steps and standardized operations under the meticulous guidance of the instructor. In physics experiments, students are fully focused, from correctly connecting circuits according to experimental requirements, adjusting the range of ammeters and voltmeters, to accurately adjusting the focal length of convex lenses to observe imaging patterns, every step is meticulous. Everyone strictly follows the operating procedures of "wiring before powering on, zeroing before measuring", carefully records experimental data, repeatedly calibrates each value, and strives to achieve precise and standardized operating procedures. In chemical experiments, everyone strictly adheres to the requirements of "proper dosage and pouring of drugs". During core experiments such as acid-base neutralization reactions, gas preparation, and property verification, everyone acted lightly and observed meticulously, accurately observing phenomena such as color changes, precipitation generation, and gas release. The teacher focuses on guiding students to handle experimental waste in a standardized manner, emphasizing the experimental principle of "safety first, standardization first", correcting non-standard actions throughout the process, and ensuring that both experimental safety and operational standards are met.

In biological experiments, microscopes become the protagonist. Students proficiently complete operations such as picking up mirrors, aligning light, and focusing, carefully making temporary slides to observe plant cell structures, explore seed germination conditions, or human blood cell morphology. From wiping the glass slide, adding clean water, to tearing off the skin and flattening the cover, every action is rigorous and meticulous. Through the microscope, students can clearly capture the subtle structures of biological samples, carefully draw experimental diagrams, proficiently master the skills of using microscopes, and enhance their abilities in biological observation and analysis. The teacher conducts full inspection and guidance, promptly corrects non-standard movements, patiently answers questions, helps students master the essentials of operation, and strengthens exam taking skills.

This drill not only familiarized students with the experimental process of the middle school entrance examination and improved their practical skills, but also cultivated a rigorous and meticulous scientific attitude. Nanchong No.11 Middle School has always adhered to the principle of "five educations" and attached great importance to experimental teaching. Through regular practical training, it helps students consolidate their subject literacy, prepare for the middle school entrance examination in the best state, and add solid confidence to their youth performance.
