Sixth-grader Sofia watched her LED circuit glow steadily. The greeting card she built over three classes carried a personal message for her brother. Her teacher at Graded — The American School of São Paulo structured the curriculum to combine technical skills with empathy and teamwork.
The three-part unit merges analog and digital circuits, coding, and hands-on prototyping using affordable materials.
Students begin by studying core ideas. They examine systems through inputs and outputs in everyday situations. A visual exercise teaches interdependence by showing how elements in images rely on each other. Sustainability enters through a breathing activity, followed by group talks about resource limits. Problem-solving connects to their own lives.
Teamwork remains central, even for solo work. Students swap feedback, adjust ideas, and revise plans when problems arise.
Light-Up Greeting Cards: Combining Creativity and Circuits
The first project teaches electricity basics—simple, parallel, and series circuits. Students build LED circuits and place them inside personalized cards. Each card targets a specific recipient—a parent, sibling, or friend—and reflects their relationship. The process covers polarity, current flow, and how inputs relate to outputs.
They test circuits using LEDs, alligator clips, and switches. For the final cards, they use copper tape, coin cell batteries, and thick cardstock. Assessment includes a short video where students describe their circuit and its intended recipient. Some share how the recipient reacted, turning a technical task into a shared experience.

Interactive Posters: Using Tech for Schoolwide Impact
The second project focuses on sustainability. Students create interactive posters that encourage energy-saving habits in school. Working in pairs, they design displays featuring slogans like “Turn off the lights when you leave.” The posters debut during Earth Week as part of a “Tech for Good” event.
The micro:bit, a $20 microcontroller, serves as the main tool. Students program it using free platforms like MakeCode and combine it with sensors, motors, and LEDs.
Smart Houses: Building Sustainable Futures
The final project asks students to design smart houses that incorporate automation and energy efficiency. Teams construct physical prototypes from cardboard and balsa wood. Sensors simulate features like smart lighting or ventilation. Some groups add AI models using simple pattern recognition tools.
The GoGo Board, an inexpensive microcontroller, handles automation. Students document their process, present prototypes in a public showcase, and justify their design choices. The project brings together everything from circuitry to sustainability. One team’s model included a solar panel that adjusted its angle based on sunlight.
The unit changes how students view technology. It becomes a way to connect and create change, not just a subject to study. Sofia’s card proved that. The LED wasn’t just a component—it was a way to reach someone. The approach shows how people value what they build themselves.
