Heterogeneous Mixture
Captions available
The idea
A heterogeneous mixture has a composition that varies from point to point within the sample.
In practice
Italian salad dressing separates into visibly distinct oil and vinegar layers, so one spoonful differs from another.
Where people slip
A mixture can look uniform at a glance and still be heterogeneous — granite appears solid-colored from a distance but shows separate mineral grains up close.
