There are many aspects of human life and production that require knowledge of atmospheric pressure and atmospheric pressure. Understanding atmospheric pressure and feeling its presence is the foundation for learning about atmospheric pressure. Air is invisible and intangible, and it is usually impossible to feel the presence of atmospheric pressure, so it is crucial to do well in demonstration experiments to ensure a successful lesson. Many experiments that are both lively and interesting and can explain the existence of atmospheric pressure have been arranged in the teaching design of this lesson. These experiments not only attract the interest of students but also allow them to truly feel that atmospheric pressure is all around us.

The teaching design of this class emphasizes practical connections, reflecting the new curriculum standard's philosophy of "transitioning from life to physics and from physics to society." It applies the knowledge of atmospheric pressure to solve real-life problems, allowing students to list their own examples of atmospheric pressure phenomena and applications in daily life. This makes students realize the ubiquity of physical knowledge in their lives and cultivates their ability to apply knowledge, as well as their emotional attitude and values of active exploration.

  Teaching objectives

1. Knowledge and Skills

（1）Through experiments, we know that atmospheric pressure exists objectively.

(2) Understand the cause of atmospheric pressure.

（3）Know the Torricelli experiment and its principle.

Understand that atmospheric pressure is related to height and weather.

2. Process and Method

（1）Through demonstration experiments, cultivate students' observation and analytical abilities.

Through the study of the Torricelli experiment, students will understand the method of using liquid pressure to study the equivalent of atmospheric pressure.

By analyzing and discussing the phenomenon of atmospheric pressure, this activity aims to cultivate students' logical thinking abilities, their ability to apply knowledge, and their awareness of teamwork.

3. Emotional Attitudes and Values

（1）Cultivate students' interest in learning through demonstration experiments and stimulate their desire for knowledge.

Through the study of the Torricelli experiment, students are cultivated to love the spirit of science.

Through understanding the application of atmospheric pressure, students can initially appreciate the close connection between physics and daily life, realizing the impact of physics and its related technologies on social development and human life.
