Seeking a Reflection on a College Physics Demonstration Experiment!!

It's not difficult, as long as you take the class seriously.

Physics laboratory course is a compulsory basic course for students to carry out basic training in scientific experiments in higher science and engineering colleges, and it is the beginning of undergraduates to receive systematic experimental methods and experimental skills training. Physics experiment courses cover a wide range of areas, have rich experimental ideas, methods and means, and can provide comprehensive basic experimental skills training, which is an important foundation for cultivating students' scientific experiment ability and improving scientific quality. This has an irreplaceable role in cultivating students' rigorous academic attitude, active sense of innovation, integration of theory with practice, and comprehensive application ability to adapt to the development of science and technology.

Teaching methods for this course: reduce intervention, give full play to students' initiative, do not explain too much, the teacher does not demonstrate, only talk about the principles and precautions.

Arrangement of experimental content: basic experiments, comprehensive experiments, design experiments or research experiments are % respectively

Experimental instruments: increase visibility, try not to use integrated instruments, and try to assemble them yourself.

Assessment of experimental results: The experimental report focuses on data processing, error analysis and after-class discussion. Don't just look at how much is written, or whether it's neat. It is best to increase the proportion of operations in class, so that students with strong hands-on ability can get a high score and stimulate their interest in learning.

The important thing is to understand and observe.

Experiments in the physics book can be written.

There is a little impression: drinking water birds.

The glass tube is an organic liquid with a very low boiling point, which exchanges heat with the outside world, especially water, through the glass tube, so that it can be easily converted between liquid and gas, making the device lose balance and swing constantly.

The glass tube is sealed, and the upper and lower decorations have two functions: thermal insulation and mechanical balance.

That's all you know.

"University Physics Demonstration Experiment" is a book published by the University of Science and Technology of China Press in 2010, the book mainly tells about the university physics demonstration experiment, the physics demonstration experiment is mainly for liberal arts students, in order to improve the scientific and cultural literacy of liberal arts students, but also can be used as a physics teaching process of classroom teaching experiment demonstration, the content is divided into mechanics, thermal and molecular physics, vibration and wave, electromagnetism, optics 5 parts, a total of 132 experimental projects, each experimental project according to the demonstration purpose, experimental principles, experimental equipment, operation and effect, thinking questions and other aspects are introduced.

The content includes mechanics, molecular physics and heat, electromagnetism, vibration and waves, optics, modern physics and synthesis, a total of 155 experiments. Each experiment is introduced according to the purpose of the experiment, the experimental instrument, the experimental principle, the operation and the phenomenon, the precautions and the thinking questions. The book can be used as a reference reading for undergraduate and junior college physics teaching in various colleges and universities, and can also be used as a reading material for physics enthusiasts.
