Road litters were collected by the present author on the city road in Okayama University, which were analyzed by students in the lectures of "Science Education in Elementary School" and "Science Education in Secondary School" in 1988 and 1992. The total 1941 litters were collected and analyzed. Of these, ones of 1562(80.5%) were burnable litters, ones of 379(19.5%) were unburnable metal/tiles and plastic goods. In burnable litters, the first place was the tobacco and relevant goods of 58.8%. The second place was the paper chip/propaganda bill/printed matter of 17.4%. The third place was the candybag/paperbag of 9.9%. The fourth place was the chewing gum/its envelope of 6.3%. The fifth place was the sanitary/medical supplies of 4.9%. The sixth place was the paper cup/paper package of 2.6%. The rest was of 1.0%. In unburnable litters, the first place was the empty can/bottle of 45.6%. The second place was the package of 36.6%. The third place was the accessory on a candy of 7.4%. The fourth place was the iron/aluminum goods/tile of 5.5%. The fifth place was the stationery goods/sport goods of 3.4%. The rest was of 2.6%. We could arouse student's interest in not only road litters but also in environmental issues. Environmental ethic education should be carried out-no smoking/ not throwaway cigarette and paper/plastic goods.
