Polarity Playground
Magnets exert a distance-dependent force: material determines whether an object responds, pole orientation determines attraction or repulsion, and field maps represent direction evidence sampled around magnets.

What your child will figure out
- Test deceptive materials and distinguish magnetic response from surface appearance.
- Predict attraction or repulsion from the poles that face each other.
- Gather evidence that magnetic interaction becomes stronger as distance decreases.
- Infer a field-direction map from several compass samples and transfer pole reasoning to a permanent-magnet puck maze.
The levels
- Force table
Freely move a magnet, then test painted steel, shiny aluminium, copper, and wood using motion only.
- Pole puzzle
Rotate a bar magnet and predict attraction or repulsion from the two facing poles.
- Distance dial
Compare the same pole interaction across distances with force arrows added.
- Compass survey
Collect six local compass directions before revealing a joined field-direction map.
- Puck maze
Guide a clearly labelled permanent-magnet puck through three gates without a field-line overlay.
Ready when they are.
