The authors could have the opportunity for the technical classes for children. The classes were carried out under the theme of "From Thermal Energy to Power of the Car" Participants were 35 boys and girls that belong to the invention club in Gamagori City. The questionnaires on thermal energy, internal combustion engine and power of the car etc were sent out on the first day and the similar questionnaires were answered on the last day. The results about questionnaires showed the encouraging effects of classes in spite of the rather difficult theme. The authors suppose that many children are interested in this theme because of the related things to the cars. The authors have learned some matters from these classes. First of all we should adopt the theme which is able to attract the concerns of children. The experiments should be certainly taken in the program and for the experiments we should prepare the matters which could be easily available. Fundamentals and principles on various scientific phenomena should be easily explained,too. It seems to be important for us to expand our actions into the community.
