摘要
将化学竞赛成果转化为具有农业特色的实验项目“纳米乳液的制备、表征及粒径调控”,并引入到物理化学实验教学中。通过实验使学生掌握纳米乳液的制备表征方法并研究制备因素对性质的影响,推动了农科和理科的融合渗透,培养了学生的跨学科思维,提高了科学素养。引导学生深刻认识纳米乳液对于减少农药使用量、保护生态环境的重要意义,关注国家粮食安全和食品安全等战略需求,加强了学生的绿色发展意识,激发了学生服务三农的责任感。
An achievement of the chemistry contest has been successfully transformed into an experimental project with agricultural characteristics,“preparation,characterization and particle size control experiment of nanoemulsion”.It’s introduced into the physical chemistry experiment teaching.Through-the experiment,students can master the preparation and characterization methods of nanoemulsion and study the influence of preparation factors on properties.That can promote the integration and infiltration of agricultural and scientific knowledge,cultivate students’interdisciplinary thinking and improve their scientific literacy.Students are guided to deeply realize the importance of nanoemulsion in reducing pesticide use and environmental protection and pay attention to the major strategic needs of national food security and food safety.The experiment can strengthen students’awareness of green development and stimulate their sense of responsibility to serve the national development of agriculture,rural areas and farmers.
