Answer: Liquids take the shape of the container that holds them
Liquids do not have a fixed shape; they take the shape of whatever container holds them, while their volume (amount) stays the same. The water changed shape in each container (tall glass, wide bowl, small cup) but the amount of water did not change. This is a key property of liquids: fixed volume, but no fixed shape. Solids, by contrast, keep their shape regardless of the container. Students may confuse 'no fixed shape' with 'no volume,' incorrectly concluding that liquids have no measurable amount, when in fact the volume of the water stays constant across all three containers.
