It was supposed that this tendency correlated with the difficulty of the contents of the science lessons. It will conclude that a curriculum should be constracted according to learner's learning process.2 Children explain new scientific phenomena for them using their own thory. This tendency developed when children grew elder. From this result, it will concluded that new phenomena timulating their thory are need to increase their emotion.Elder children like national environment and disease, but don't like dissamble of machine, biology and heavenly bodies. Scientific practice is decreasing when children become elder.4 Three types of science lessons were caried and evaluated.
