From the analysis of the material properties, it was found that by changing the shape and salt content of the conductive clay, it was possible to easily create electrical resistances with various resistance values and resistivities. Furthermore, by connecting in series and parallel, it was found to be a teaching material that can also be applied to experiments on combined resistance. In addition, through the practice of obtaining the resistivity, shape, and resistance values of electrical resistance by the experimental group and the control group, we were able to confirm that conductive clay is effective in promoting the formation of scientific concepts concerning the shape and resistance of electrical resistance, forming the concept of synthetic resistance using shapes, deepening interest and improving the level of understanding of basic calculation problems in the electrical field.},
