Light & Shadow Games — Predict, Watch, Understand
These free light games let a young child predict what light and shadows will do, watch it happen, and see why. Shadows grow and shrink, and you cannot see a thing in a dark room — simple to watch, surprising to guess. Made for the youngest learners: no reading-heavy setup, no ads, no sign-up.
Predict what a shadow does — move the lamp closer and the shadow grows, because light travels in straight lines.
Predict whether you can see an object in the dark — you only see when light bounces off it into your eyes.
What kids learn
Light travels in straight lines. When an object blocks it, it casts a shadow on the far side — and the closer the light, the bigger the shadow. And we only see because light bounces off things into our eyes, so in total darkness there is nothing to see. Each game isolates one of these ideas and lets the child test a hunch against what really happens.

Common questions
Can you see in the dark?
No. You can only see when light bounces off an object and travels into your eyes. In a truly dark room there is no light to bounce, so you see nothing — your eyes do not make their own light, and they cannot "adjust" to see in total darkness.
Why do shadows change size?
Light travels in straight lines, and an object blocks it to make a shadow. When the light source moves closer to the object, the shadow gets bigger; when the light moves farther away, the shadow gets smaller. The sun low in the sky makes long shadows for the same reason.
How is a shadow made?
A shadow forms when an object blocks a source of light, stopping the light from reaching the surface behind it. That leaves a dark shape — the shadow — on the side opposite the light.
What age are these light games for?
Roughly ages 6–9 (grades 1–3). Light, shadows, and how we see are grade-1 science topics, and the predict-and-watch format needs no reading-heavy setup — a good fit for the youngest learners.
