This paper examines when and how children obtain the concept of the three different terms, stones ("ishi"), rocks ("ganski") and minerals ("koubutsu"), in their growth process. To this end, the questionnaire was addressed to elementary-school students and adults including earth science experts who live in Shiga prefecture. As a result, the following facts were identified. First, the students responded to the questionnaire learned the conception of stones before nursery school (or kindergarten), while living with their family, especially their mother. Regarding rocks, they acquired the concept not only from their parents but also from their ordinary daily experiences. Also, they were taught the idea of "sedimentary rocks" in 6 grade science classes. However, analysis of the survey showed that there are many children who know words of rocks and minerals at the end of primary school. This may suggest that the naive concept of rocks and minerals should be taught from a scientific viewpoint at an earlier stage of elementary school, focusing on the relation between them. On the other hand, the adults including earth science experts hold the same definition of rocks and minerals in common, though the concept of stones is not clear enough to them, and interestingly, they are familiar with the relation between rocks and minerals. Considering these findings, it may be concluded that in teaching two different terms, it is very much significant for students to recognize that rocks are composed of minerals.
