What are the physical, chemical and biological experiments for the high school entrance examination?

Physical, chemical and biological experiments in the high school entrance examination usually include the following content:

1. Physical experiments: such as measuring the weight, length, time, etc. of objects, and exploring basic physical concepts such as force, energy, and work.

2. Chemical experiments: such as exploring basic chemical phenomena such as acid-base neutralization, gas preparation, and electrolysis of water.

3. Biological experiments: such as observing the cell structure under the microscope, observing the photosynthesis of plants, observing the growth and development of animals and other basic biological phenomena.

The above are only some common experimental contents, and the specific content depends on the local syllabus and examination requirements.

For the practical exam, students need to draw lots to decide their exam content, including twelve questions in physics, six questions each in chemistry and biology. Students will take two questions, including one in physics and one in chemistry or biology. The time is ten minutes and the score is twenty points, which will be scored on the spot by the supervising teacher of each experimental station.

The 2023 high school entrance examination physics, chemistry, and biology experimental operation exams are based on the following basic principles:

1. The exams are based on the standards. To implement the compulsory education curriculum standard requirements, the test questions and test points are derived from the current textbooks, highlighting the basic experimental operations in the textbooks, and not increasing the students' academic burden.

2. Proceed steadily. The test content and question types are relatively stable, and the difficulty of the experiments and the scoring standards are roughly the same as in previous years, reflecting the guiding requirements of experimental teaching and gradually improving students' scientific literacy and experimental operation abilities.

3. Consider both urban and rural areas. The experimental operation examination takes into account the actual practice of experimental teaching, takes into account the differences between urban and rural areas, and strives to be fair and impartial in the examination.

Grading method: Each subject is assigned 2 invigilators, who are responsible for the invigilation of experimental operations and on-site grading of the subject. The experimental operation test score is the average of the scores of two invigilators in the same discipline. The invigilator will evaluate and score based on the student's on-site experimental operation procedures and steps, and confirm with his signature.

Result application: The full score of the physics, chemistry, and biology experimental operation examination questions is 100 points, and the points will be converted according to certain rules when included in the total score of the high school entrance examination. Among them, if the score of the experimental operation test is 60 points or above, 10 points will be counted into the total score of the high school entrance examination; if the score of the experimental operation test is below 60 points, 5 points will be counted as the total score of the high school entrance examination; those who are absent from the exam or have no hands-on operation will be counted as 0 The points are included in the total score of the high school entrance examination.
