Debao Hemispheric Test Courseware

In human life and production, knowledge of atmospheric and atmospheric pressure is essential in many areas. Understanding and experiencing atmospheric pressure is the foundation for learning related concepts. Air is invisible and intangible, and we usually cannot sense its presence, so conducting effective demonstration experiments is crucial for this lesson. This lesson includes many lively and interesting experiments that illustrate the existence of atmospheric pressure. These experiments not only engage students but also help them truly realize that atmospheric pressure is all around us.

In the teaching design of this lesson, emphasis is placed on connecting with real life, reflecting the new curriculum standards' concept of “moving from life to physics, and from physics to society”. Students are encouraged to apply the knowledge of atmospheric pressure they have learned to solve practical problems. By listing phenomena related to atmospheric pressure and their applications in daily life, students can appreciate the universality of physical knowledge in everyday life, while also developing their ability to apply knowledge and their positive emotional attitudes and values towards exploration.

【Teaching Objectives】

1. Knowledge and Skills

(1) It was determined through experiments that atmospheric pressure exists objectively.

(2) Understanding the mechanism behind atmospheric pressure.

(3) Knowledge of the Torricelli experiment and its principle

(4) Understand that atmospheric pressure is related to altitude and weather conditions.

2. Process and Methods

(1) Through demonstration experiments, students' observation and analysis skills can be developed.

(2) Through studying the Torricelli experiment, students can understand the equivalent substitution method of using liquid pressure to study atmospheric pressure.

(3) Through the analysis, discussion, and explanation of atmospheric pressure phenomena, students’ logical thinking abilities, ability to apply knowledge, and sense of collaboration with others are developed.

3. Emotional Attitudes and Values

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

(2) By learning from the Torricelli experiment, students' love for science is cultivated.

(3) Through understanding the application of atmospheric pressure, students gain an initial insight into the close connection between physics and daily life, enabling them to recognize the impact of physics and related technologies on social development and human life.
