The present author hypothesizes and analyzes a children's logic of proposition in judging whether or not propositions on the concepts of physics and chemistry are true. His main findings include: 1) when children try to judge whether or not propositions on concepts of physics and chemistry are true, some of them adopt a children's logic of proposition, except for two-valued logic; 2) there are instances in which the children's images of science and technology influence their judgment about the propositions ; and 3) children's experience and familiarity with electromotive toys and household electric appliances influence their judgment about the propositions.
