Energy Games — Predict, Watch, Understand
These free energy games let a child predict what energy will do, watch it happen, and see why. Energy is full of ideas that feel slippery — a still ball up high is "loaded," rubbing makes heat, and energy is never really used up — so guessing first, then watching, is how it makes sense. No ads, no sign-up.
Predict the form — light, heat, sound, electrical, motion or chemical energy.
Predict what rubbing does — friction turns motion into heat; rougher and faster makes more.
Predict the energy — stored up high or in a spring, or the energy of motion as it is released.
Predict what energy becomes — a bulb turns electrical into light; your body turns food into motion.
Predict which sources last — sun, wind and water refill; coal, oil and gas run out.
Predict where energy goes — it is never destroyed; the "lost" bit became heat and sound.
What kids learn
Energy is the ability to make things happen, and it comes in forms — light, heat, sound, electrical, motion and chemical. It can be stored (potential) or moving (kinetic), and it constantly transforms from one form to another — but it is never created or destroyed, so the total is always conserved (the "lost" energy usually became heat). Some sources renew and some run out. Each game isolates one of these ideas.

Common questions
What is the difference between kinetic and potential energy?
Potential energy is stored and ready to go — a ball held up high, a stretched rubber band, water behind a dam. Kinetic energy is the energy of motion — anything moving has it. As a raised ball falls, its potential energy turns into kinetic energy, and the higher it started, the more it had.
Does energy get used up?
No — this is the big idea of energy. Energy is never created or destroyed, only changed from one form to another (the Law of Conservation of Energy). When a bouncing ball bounces lower each time, the "missing" energy did not vanish — it turned into heat and sound. The total always stays the same.
What are the forms of energy?
Energy comes in several forms: light, heat (thermal), sound, electrical, motion (kinetic), and chemical (stored in food and fuel). Many things have more than one — a campfire gives off both heat and light, and a battery stores chemical energy it turns into electrical.
What makes an energy source renewable?
Renewable sources are naturally replaced and will not run out: sunlight, wind, and flowing water. Non-renewable sources — coal, oil and natural gas, the fossil fuels — took millions of years to form and will eventually run out once we use them.
What age are these energy games for?
Roughly ages 8–13 (grades 3–8), and each game shows its grade band. Forms of energy and friction-heat suit grades 3–6; kinetic/potential, transformations and renewable energy reach grades 4–7; conservation of energy is grades 5–8. The predict-and-watch format needs no reading-heavy setup.
