What Players Actually Do
Each round shows one familiar object: a fruit, a toy, a tool. The player taps or clicks one of two options: float or sink. A brief animation then shows what happens in the water. Correct calls increase the score; incorrect calls show the real result without penalty or lecture. That immediate visual feedback is the whole teaching loop, and it repeats across a varied set of items.
Why the Object Set Matters
The learning comes from the objects themselves. They are chosen to represent different materials and shapes, so children encounter metal, stone, plastic, cork, and hollow forms in context. A dense metal tool and a light plastic toy behave differently for reasons a child can start to notice. The game does not explain density with text; it lets repeated outcomes build the pattern.
Designed for Young Learners and Classrooms
The interface stays clean and distraction-free, with no external links or ads aimed at children. Because the controls are a single tap on one of two choices, pre-readers can play independently. Teachers can also use rounds as discussion prompts: ask why a prediction was right or wrong before revealing the animation. The item order may vary between sessions, which keeps replay fresh without changing the core task.
Building Prediction Accuracy
Score tracking gives a simple progress signal across multiple rounds. Accuracy improves when players consider material first, then size and shape. A large flat object may displace more water than a small dense one, so shape is not decoration. The game rewards careful observation rather than speed, and mistakes are corrected visually, not punished.
