妈妈在中医院上班，每天都要给不少的病人熬中药，常常因把药渣倒入药液中而烦恼。我在“创适发明目”活动中，上交了这一课题，铺导者师在上科技课的，向全班同学表扬了我，能找到这样的好课题，真不错，我喑地下决心要把这件作品研制出来。我常留到妈妈用一块铁片挡住药渣，? Mom working in a Chinese medicine hospital, every day to a lot of patients boil Chinese medicine, often due to the dregs into the liquid medicine and trouble. In the activity of “inventing the right inventions”, I handed in the subject, and the mentor was in science and technology class, praised me to the classmates and found such a good subject. This work should be developed. I often stay with my mother to block the dregs with a piece of iron.
