Abstract
There are a lot of scientific phenomena and technological matters around us. Teaching materials in the science classes for children carried out last year were discussed in this report. The authors have learned some aspects from the science classes. First of all we should adopt the materials which are familiar to children and are able to attract the concerns of them. Secondly, the experiments should be certainly taken in the programs and for the experiments we should prepare the materials which could be easily available. Special tools should not be considered because children could not use. Expensive materials should not be considered because children could not get. Finally, fundamentals and principles on various scientific phenomena should be easily explained. It was expected that explanations about fundamentals and principles should be done after experiments or making. The results about questionnaires showed the encouraging effects of classes. It seems to be important for us to expand our actions into the community.
