The purpose of this study was to develop a logic gates experimental module for enlarging and deepening the learning of electrical circuits for elementary and junior high school students. The module includes a NOT gate, a NAND gate, a NOR gate, a battery, and a buzzer. So far, this experimental design has not yet been included in elementary and junior high school science and technology textbooks. Therefore, the logic gates can serve as new teaching aids for teaching simple electric circuits and basic concepts of logic in elementary and junior high school curriculum.
