This paper introduced the teaching design idea of the course "the influence of temperature and pressure on chemical equilibrium" It mainly showed that how to use abundant experimental materials to help students establish the influence law of temperature and pressure It mainly involved two links (1) Through discussing the changing process of three different balance systems in ice water and hot water bath, the teacher guided the students to break the misconception of temperature condition and establish scientific laws (2)Through analyzing the characteristics of pressure change in the process of steam-water balance and NO₂ balance movement represented by hand-held technology, teachers guided students to establish the influence law of pressure.
