Electronics Lab

Snap together batteries, bulbs, and switches in a live circuit simulator — bulbs really glow, shorts really trip — and work up from first circuits to breadboards and Ohm's Law.

Grades 3–8Physical ScienceElectronics

Electronics Lab is a live circuit simulator with real physics under the hood. Students snap batteries, bulbs, switches, and wires together and see honest results instantly — bulbs glow brighter or dimmer based on actual circuit math, short circuits trigger warnings, and meters read true values. Components look like the real parts first; a schematic view builds symbol literacy as students advance.

Guided units walk the class from "what is a circuit?" through series and parallel circuits, switches, troubleshooting, Ohm's Law, and breadboards — each with challenges and quick quizzes, plus optional try-it-for-real extensions using simple classroom materials.

How a class uses it

  • Start with the first units: light a bulb, then discover why series circuits dim and parallel circuits don't.
  • No parts kits required — every student experiments safely, and nothing burns out for real.
  • Extend into the physical world: units include hands-on companion builds, like a cardboard-and-brad switch or a real breadboard circuit.
