1. Physical experiments: such as measuring the weight, length and time 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 electrolytic 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 just some common experimental contents, depending on the local syllabus and examination requirements.
In practice, students need to draw lots to decide their own examination contents, including twelve questions in physics, six questions in chemistry and six questions in biology. Students take two questions, one in physics and one in chemistry or biology. The time is ten minutes and the score is twenty. The invigilator of each experimental platform will score on the spot.
In 2023, the physics, chemistry and biology experimental operation examination for the senior high school entrance examination is based on the following basic principles:
1, according to calibration test. To implement the requirements of compulsory education curriculum standards, the test sites come from existing teaching materials, highlight the basic experimental operation in teaching materials, and do not increase the academic burden of students.
2. Steady progress. The content and type of the examination are relatively stable, and the experimental difficulty and grading standard are roughly the same as those in previous years, which reflects the guiding requirements of experimental teaching and gradually improves students' scientific literacy and experimental operation ability.
3. Give consideration to both urban and rural areas. The experimental operation examination takes into account the experimental teaching practice, the differences between urban and rural areas, and strives for fairness and justice in the examination.
Scoring method: Each discipline has two invigilators, who are responsible for the invigilation and on-site scoring of experimental operations in this discipline. The test scores of experimental operation are the average of the scores of two invigilators, and the invigilator scores them according to the students' on-site experimental operation process and steps, and signs them for confirmation.
Application of grades: The full marks of physics, chemistry and biology experimental operation questions are all 100, which are calculated according to certain rules when included in the total score of senior high school entrance examination. Among them, if the experimental operation test score is 60 or above, it will be included in the total score of the senior high school entrance examination according to 10; Experimental operation test scores below 60 points, according to 5 points included in the total score of the senior high school entrance examination; If you are absent from the exam or have not started the operation, the total score of the senior high school entrance examination will be counted as 0.
