All the students competed to design a 11 model and make it "smart" .Liu Tianyou, 12, with 12 teammates, used computer programs and sensors to finish it. "If you open the door of the house, the lights will 13 automatically, "he said. Their work won the third prize.

    The class, develops students' creativity as well. 14 Learning mechanies and programming in the class, Zhao Hngyi, 14, made a Lego robot himself in eight 15.From assembling(组装)to testing he finished it on his own.
