The most interesting foundation constitutes the model airplane course.

Last Wednesday afternoon, we had a lively and interesting model airplane class in Class 3 (4).

When the bell rang in the second class, Mr. Yang, who was teaching our science class, hurried into the classroom with a big box in his hand. The students all looked at the big box with excitement and curiosity, wondering what treasures were in it. Teacher Yang smiled and said to everyone, "Today we are going to have a model airplane class." He opened the box, which was filled with all kinds of model airplane materials. Teacher Yang asked us to open the package first, and then began to assemble: the propeller, fuselage and hook connected by rubber bands were combined into a model helicopter.

The model airplane is ready, and it's time to show off! Under the leadership of Teacher Yang, the students rushed to the playground like happy birds. The students lined up and flew one by one. I gently turned the propeller back a hundred times to prepare for the test flight. Finally, it was my turn. I held the fuselage in my left hand and the pole in my right hand, only to hear the teacher say, "fly!" " "I let go, the helicopter flew. Like a disobedient child. It flew a little high and began to fall. It also kissed my face. Just when I thought it was going to land in despair, it flew tenaciously again, reaching nearly four stories high and almost flying over the campus wall. This interesting scene made the students laugh.

Unconsciously, the bell for doing exercises rang. The students reluctantly left the playground with their beloved model planes.
