"Pressure" PPT courseware

Teaching background

Pressure is an important content in mechanics and is widely used in real life. Students are familiar with the physical phenomena related to pressure, but the concept of pressure is still relatively unfamiliar to students. The teaching material in this section is mainly based on the students' preliminary knowledge of force, and the specific analysis of another type of effect of force after learning the relationship between the change of the object's motion state and force. Pressure is the foundation of the entire chapter and an important guarantee for students to learn liquid pressure and atmospheric pressure well. Therefore, teaching under pressure is the key to teaching this chapter well.

teaching objectives

1. Be able to explore through experiments the relationship between the effect of pressure, the size of the pressure and the force-bearing area.

2. Be able to describe the process of establishing the concept of pressure, skillfully write pressure formulas and units, and be able to use pressure formulas for simple calculations.

3. Be able to apply pressure formulas to analyze specific methods of increasing or decreasing pressure, and be able to explain physical phenomena related to pressure.

Learning methods

(1) Students’ existing cognitive foundation and learning disabilities:

Have a preliminary understanding of the effects of elasticity, gravity, friction and force, and have preliminary force analysis capabilities. But many students think that pressure is gravity.

(2) Students’ existing skill base and learning barriers:

Students have basic observation, analysis, and induction abilities. However, in exploratory experiments, the design of the experiment is not rigorous enough; the ability to find patterns through experimental phenomena is still relatively weak.

Teaching process

Study 1: The relationship between the effect of pressure and the amount of pressure

Design guidance:

The physical quantity that should be controlled is: force area

The physical quantity that should be changed is: pressure

The effect of pressure is shown by the degree of foam depression.

Exploration 2: The relationship between the effect of pressure and the force-bearing area

Design guidance:

The physical quantity that should be controlled is: pressure

The physical quantity that should be changed is: force area

The effect of pressure is shown by the degree of foam depression.

Teaching reflection

In the design of this lesson, I followed the spirit of the new curriculum standards, guided by the modern classroom teaching concept, based on experimental activities, and adopted an inquiry-based teaching method to allow students to fully play their main role while striving to highlight the practice of the classroom sex and innovation.

1. Provide dynamic and real object scenes through experimental equipment to inspire students to understand principles in objects. Strive to embody the characteristics of physics classes that “come from life, go to life” and strive to apply what you have learned.

2. Pay attention to the process and method of establishing the concept of pressure. Students participate in exploration and exchange in a harmonious and equal atmosphere, and adopt the multiple teaching model of "student-student interaction" and "teacher-student interaction" to achieve the transformation from "learning" to "knowing how to learn".
