PowerForge

Meet the cast who each embody one piece of energy — then engineer a grid with them.

Engineer, investigate & practice

Five surfaces — four hands-on engineering & physics labs plus the concept quiz. Everything runs on your device; nothing is sent anywhere.

Grid Balancer Allocate solar, wind, hydro, nuclear and gas to meet real demand — exactly. Watch the supply, cost and CO₂ meters, and hit clean-energy goals without a brownout. Engineer Day-Cycle Grid Keep one city powered from dawn to night. Re-balance the same grid as the sun rises and sets, the wind shifts, and demand peaks in the evening — then see your whole-day cost and carbon. Engineer Energy-Conversion Chain Trace energy from its source to its use — chemical to heat to motion to electricity to light — and see where it slips away as waste heat. Energy is never lost, only converted. Investigate Energy Ramp Release a cart down a ramp and watch stored (potential) energy become motion — with friction bleeding some off as heat. Predict the speed, whether it clears the next hill, and where the energy goes. Investigate Circuit Lab Wire bulbs in series or parallel and predict the current, the power, and how bright each bulb glows before the meters reveal it — Ohm’s law (I = V ÷ R) and electrical power (P = V × I), hands-on. Investigate Concept Kits 16 quiz kits — 400 questions from forms of energy to the power grid, renewables, thermodynamics and nuclear — with a hint after a first miss and an explanation every time.

Play together

Go head-to-head with a friend — same device or an online room.

PowerForge Duel (pass-and-play) 2–4 players take turns on one device — same questions, highest first-try score wins. Or open an online room to play a friend on another device. PowerForge Journey — follow the map → A path through every kit. Clear each stop, then move on — see how far you’ve come.

Mixed practice

Mixed practice — revisit what you've learned A short round that shuffles questions from the kits you've played, brought back when they're ready to review. Great for making it stick. PowerForge Sprint — a calm speed round → Once you’ve mastered a few kits, race your OWN best on what you already know. Timer optional, no penalty for a miss.

Same idea, another world

Something you practice here shows up somewhere else too — that's real learning that travels.

Height turning into speed on a ramp is energy being conserved — the same trade a machine makes when it swaps force for distance.The shared idea: conservation of energy — energy is never lost, only traded (height becomes speed as potential energy turns into kinetic), the same bookkeeping as a machine that trades force for distanceTry MachineForge →
