This research examined age differences in the way 3-, 4-, 5-year-old children solve scientific problems involving magnetic and nonmagnetic objects. Their scientific process skills and scientific concepts were examined in 1) hypothesis setting, 2) hypothesis verification and 3) hypothesis application. Data was analyzed by one-way and two-way ANOVA and Scheffe. Children's scientific process skill presented differences by age in each phase of problem solving. That is, the scientific concept level demonstrated by 4-year-olds was higher than that of the 3-year-olds. That of the 5-year-olds was higher than the 4-year-olds. In addition, in all age groups, the children showed a higher level of understanding about magnetic and non-magnetic objects in the hypothesis application phase than in the hypothesis setting phase.
