Lower Elementary students, aged 6-9, embarked on an engaging project to learn about simple circuitry. The project began with an introduction to creating closed circuits, where students used a Makey-Makey device in conjunction with their own bodies. This concept was illustrated in a diagram shown in the above left image, providing a visual aid to their learning.
Building on this foundational knowledge, the students progressed to constructing circuit maps, which deepened their understanding of sensors and circuits. They used color-coded jump wires, specific sensors, and an Arduino Nano that had been pre-programmed to operate with their sensor. To visualize their projects, students glued paper cutouts representing each sensor and the Arduino Nano onto a base, drawing connections between them with color-coded markers to match the jump wires. This activity not only reinforced their learning but also required them to follow the circuit map they created to assemble their own working sensor, blending creativity with technical skills.
