The purposes of this study were (1) to investigate the differences in the level of children`s knowledge and reasoning skills due to the sloping phenomenon according to their ages and the types of tasks they were asked to perform and (2) to investigate whether children`s prior knowledge is changed to post knowledge through their reasoning. A total of 120 subjects forty from each of the age groups 4, 6 and 8 were selected for the study. The major findings are presented below: 8-year old children showed higher levels of prior knowledge than 6-year old children. The prior knowledge level of the “size” task was higher than that of the “weight” task. 6-and 8-year old children showed higher levels of reasoning than 4-year old children. The reasoning level of the “size” task was higher than that of the “weight” task. 6-and 8-year old children showed higher levels of post knowledge than 4-year old children. However there was no difference in children`s post knowledge according to task difference. Through the different types of reasoning involved in the children`s performances of the two tasks changes in the prior knowledge of the sloping phenomenon were observed among all age groups.
