College physics experimental projects cover a wide range, which based on rigorous theory andexperimental means.This course provides students with basic experimental skills training,which is an importantmeans to cultivate studentsscientific thinking and improve their scientific literacy.However, there are someproblems such as lack of innovation and lack of integration with life in university physics experiment course.Inthis experiment,thermistor is used to replace the fixed value resistance as the research object,and Wheatstone bridge is used as the carrier to study the relationship between the resistance value and temperature of NTC typethermistor at different temperatures.By fitting the variable relation between temperature and resistance value.the function relation of resistance value changing with temperature is obtained. And then ,the resistance value atany temperature can be obtained.Since thermistors can be seen everywhere in daily life , students’ interest inlearning can be enhanced.This operation can improve the expansion of basic physics experiment,and improvestudents’ practical ability and innovation ability. So students can understand the resistance temperature characteristics of negative temperature thermistor while mastering the working principle of Wheatstone bridge
