Waves Games — Predict, Watch, Understand
These free waves games let a child predict how waves behave, watch it happen, and see why. Waves are everywhere yet easy to misread — energy travels while the water stays put, taller means louder, closer crests mean higher pitch — so guessing first, then watching, is how it makes sense. No ads, no sign-up.
Predict what counts as a wave — a traveling disturbance that carries energy, not matter.
Predict the energy — a taller wave carries more; louder sound, bigger splash.
Predict the trade — crests close together mean high frequency and a short wavelength.
Predict the path — sound waves vibrate the eardrum, then signals travel to the brain.
Predict the spectrum — radio, visible color and X-rays are all light waves of different lengths.
Predict what moves — a wave carries energy from place to place, while the matter bobs in place.
What kids learn
A wave carries energy without carrying the matter along. Its amplitude sets how much energy it delivers, while wavelength and frequency trade off to set pitch and color. Sound waves are turned into signals by the ear, light is a wave spanning radio to X-rays, and in every case the wave carries energy from place to place. Each game isolates one of these ideas.

Common questions
What is a wave?
A wave is a traveling disturbance that carries energy from one place to another. Water ripples, sound, light, and a wiggle sent down a rope are all waves. The key idea is that the energy moves along while the matter mostly stays put — a floating duck bobs up and down as a wave passes but does not travel with it.
What do amplitude and wavelength mean?
Amplitude is the height of a wave, measured from the middle to a crest — a bigger amplitude means more energy (louder sound, bigger splash). Wavelength is the distance between two crests. Frequency is how many waves pass each second: crests close together mean high frequency and a short wavelength.
Is light a wave?
Yes. Light travels as a wave, and the colors we see are just a small slice of a much larger family of light waves — the electromagnetic spectrum — that also includes radio waves, microwaves, infrared, ultraviolet and X-rays. Different colors are different wavelengths, and light can travel across empty space, which is how sunlight reaches us.
What age are these waves games for?
Roughly ages 8–13 (grades 3–7), and each game shows its grade band. What a wave is, how ears hear and waves-carry-energy suit grades 3–6; amplitude, wavelength/frequency and light-as-a-wave reach grades 4–7. The predict-and-watch format needs no reading-heavy setup.
