Abstract Preparation and properties of CO2 are important content in junior high school chemistry. The experiments in textbooks were usually demonstrated by teachers, rather than operated by students. Using plastic cups, plastic spot plates and plastic syringes, this paper designed the integrated experiments of preparation and properties of CO2 (including density, non-combustion, and solubility of CO2 and reaction with lime water).The apparatus were small and easy for students to operate in groups, which encouraged students to participate in the experimental activities. Meanwhile, the way and strategies of thinking derived from these experiments provided reference for other experiments.
