This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A heterogeneous mixture has a composition that varies from point to point within the sample.
Show
Italian salad dressing separates into visibly distinct oil and vinegar layers, so one spoonful differs from another.
Watch for
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.
