3M青年科学家挑战赛是一年一度的针对中学生的全国竞赛，参赛学生的任务是提出一个解决现有问题的想法或发明。
Ten finalists are chosen to compete for the title of "America's Top Young Scientist" and a grand prize of $25,000. After being selected, they work with scientists at to make their idea come to life.
10名参加决赛的选手被选出来角逐“美国顶尖青年科学家”的头衔和25,000美元的大奖。决赛选手被选出来之后要和科学家一起将他们的想法付诸实践。
Each contestant is judged on their invention's creativity, scientific knowledge, persuasiveness and communication, and overall presentation.
要对每位选手的发明创意、科学知识、说服力和沟通力，以及综合阐述进行评判。
Other finalists included Jaya Choudray, who invented an airflow control robot that works to reduce energy consumption in a home, and Caroline Crouchley, who invented a climate-friendly transportation system that would eliminate the need for a diesel engine or electric motors.
其他决赛选手有Jaya Choudray，发明了一个可以减少家庭能源消耗的气流控制机器人；Caroline Crouchley发明了一种气候友好型交通系统，可以省去对柴油机或电动机的需求。
3M holds the competition for students in grades 5-8 because research has shown that their interest in science fades after these years.
