Third and fourth graders become engineers on Thursday afternoons.<\/p>\n
The topic today are touch sensors. \u201eWhere do you find them in everyday life?\u201d, asks the teacher of the extra-curricular activity. Many children raise their arm; some are very excited and shout that they want to give the answer.<\/p>\n
I learn that touch sensors are used in elevators and air bags. After this short introduction, the programming begins. In pairs or by themselves, the students program their cars to go for a certain amount of seconds and then stop. They cheer each other when their cars do what they are supposed to do on the test drive, i.e. the floor at the back of the classroom.<\/p>\n\n\t\t
