A few days ago，The electrical engineering subject experimental platform welcomed an unusual group of visitors，Children from the large class section of the Third Kindergarten of Shandong University。
In order to implement the "Learning at Shandong University" proposed in the report of the school's 15th Party Congress、Education system for happy growth，Make full use of the rich educational resources of Shandong University，Encourage children to observe、Perception、Experience the magic and charm of science through operation and discovery，The Third Kindergarten of Shandong University Contact the School of Electrical Engineering，Together we planned this special electrical exploration trip for the children。
To ensure the safety and smooth conduct of this event，Teachers from the Experimental Center of the School of Electrical Engineering have conducted many communications with kindergarten leaders and teachers，Field demonstration experiment content、Safety hazards and safety measures to be taken, etc.，Safety and content preparations have been made for this exploration activity。
The children in the large class section of the Third Kindergarten of Shandong University are in good order、After entering the laboratory politely，The teachers first discussed with the children the role of electricity in life。Also by watching animation，Guide children to understand the production of electricity、Transfer and use，And future power grid development trends and electric energy production、Globalization of transmission。After，Teachers and children summarized common unsafe electricity usage behaviors in life，Guide children to establish the concept of safe use of electricity。
After fully understanding the magical process of electricity production and use and being prepared with safety knowledge，The teachers led the children to visit the large-scale generating units in the Power System Dynamic Simulation and Simulation Laboratory，Guide children to understand the main structure of large-scale units and their control equipment。Afterwards，The children came to the new energy refined simulation modeling and grid connection test laboratory，Watched the demonstration of the wind turbine mathematical model，Learned about the important components of wind turbine。The on-site engineer also demonstrated the cross-sectional model of the wind turbine to the children，Make it intuitive to understand the internal structure of the wind turbine。
The next step is an interesting hands-on experiment session，Under the demonstration and guidance of teachers，Let the children connect the hand generator and small lamp beads by themselves，Experience that the motor can light up the lamp beads after generating electricity，And rotating the motor handle forward or reverse can light up the small lamp beads。After，Let the children connect the hand generator and the light-emitting diode，Find the direction of rotation of the motor handle that can light up the LED，Understand the unidirectional conductive characteristics of light-emitting diodes。The children are very focused on exploring this little experiment，When lighting the lamp beads and light-emitting diodes，will cheer，Full sense of accomplishment。
The children finally reluctantly left the School of Electrical Engineering，This laboratory exploration activity was a complete success。Next step，The subject experiment platform of the School of Electrical Engineering will continue to respond to the "Outline of the Action Plan for National Scientific Literacy"，Actively carry out science popularization work，To the public、Primary and middle school students、Students from other disciplines display cutting-edge scientific and technological achievements，Scientific inquiry skills among adolescents and college students、Critical thinking and empirical spirit、Continue to play an active role in cultivating the quality of scientific attitudes and values。
