I Built a Quiz That Grades Itself Using Circuits! #physicsiscool

In this project, students use DIY circuits to create a light-up quiz board that gives instant feedback—if the answer is correct, the LEDs turn on! This compound circuits project is a perfect way to combine STEM learning, engineering design, and content knowledge from any subject. My students used world history maps, but this can easily be adapted for science, math, vocabulary, or any classroom. Students design a parallel circuit with three branches, where each branch includes: 2 LEDs in series: https://urlvue.com/r/5ge3boqdsb a 150 ohm resistor: https://urlvue.com/r/v4v5rx7gdc powered by a 9V battery: https://urlvue.com/r/k0ftukln17 copper tape: https://urlvue.com/r/uxz5p39nhf 9V battery snaps: https://urlvue.com/r/l0r4guwyyb They build their circuit on cardboard, overlay a visual (like a map), and use copper tape or wires to create switches. When a student selects an answer and closes the switch, the circuit completes—and the LEDs light up if the answer is correct. This is a great project-based learning (PBL) activity that gets students engaged, thinking critically, and applying real engineering concepts.
