Spark Lab

Spark Lab is a cartoon circuit game that teaches electricity from scratch. Drag wires between batteries, bulbs, switches and more, and watch what really happens: bulbs glow brighter or dimmer, LEDs only work one way round, too much power makes things pop, and the moving dots show the current flowing. Two ways to learn: - Just show me: friendly explanations, no maths needed. - Teach me properly: real volts, amps and ohms, with the formulas behind each challenge. What's inside: - First Light: 8 challenges covering loops, switches, series and parallel circuits, resistors and LEDs. - Safety & saving: fuses, a mains safety quiz, and a calculator comparing what old bulbs and LEDs cost to run, in rand. - School projects: conductor tester, house wiring, burglar alarm, lemon battery, steady-hand game and a night light. - Magnets & motors: electromagnets, spinning motors, speed control and a two-speed fan. - Logic gates: build AND and OR gates from switches, with a live truth table. - Solar: power an LED from the sun, then build a solar charger. - Free build: 13 parts to experiment with. Switch to "Circuit diagram" view at any time to see your circuit drawn with standard symbols. Made for learners from about Grade 6 to Grade 9, and for curious adults. Activities are matched to topics in the South African CAPS curriculum. Progress is saved in your browser.
