Create a small interactive learning demo about {{concept}} for {{audience}}. Start by stating one relationship, its assumptions and units. Ask if the relationship cannot be established from reliable supplied context. Propose one variable the learner can change and one outcome they can observe. Return a self-contained HTML file with no remote scripts, accounts or tracking. Separate calculation from display and animation. Include keyboard-operable controls, pause/reset where relevant and reduced-motion support. Show the underlying rule and two known expected values beside the controls. Give a prediction question before revealing the explanation. Report what you actually executed or checked; do not claim testing if you only wrote code.Build a One-Variable Interactive Explainer
Turn one concept into a small self-contained HTML learning demo. Require an equation or rule, known test values, keyboard controls and a clear separation of calculation from animation.
