Tween Tinkerers (Ages 10–12)

Children here are ready to experience the full design‑make‑test‑iterate cycle. They can log sensor data, solder simple circuits, design parts in Tinkercad for 3‑D printing, and build servo‑driven cardboard robotic arms. Adults provide a safety briefing and supervision around soldering, power management, and 3‑D‑printer use, then step back so students can plan, troubleshoot, and learn from their own mistakes.
