Abstract This paper simulated large-scale science popularization and truth seeking programs Is it true to create learning atmosphere.Based on the reality of daily life and production, “Can N2 be used to replace CO2 in daily fire fighte”, “Can regulate the greenhouse effect through CO2 capture in deep sea” and “In the oil mining industry, can a ton of CO2 be injected into an oil well to increase crude oil production by 3~5 tons” and “Can we keep eggs fresh with lime water” and other three small questions, which are difficult to distinguish, guide students to deeply understand the nature of carbon dioxide from the positive perspective of chemistry;Using mobile magnetic pasteboard to design blackboard writing, guide students to experience and construct structured knowledge system.
