Preschoolers do NOT have an understanding of conservation of liquid or mass.

Question

Quizplus · Accepted Answer

Preschoolers have not yet developed the cognitive ability to understand conservation of liquid or mass. They may, for example, believe that pouring the same amount of water into a taller and narrower glass means that there is now more water. This is because they focus solely on the perceptual aspect (height of the glass) rather than the actual volume of the liquid.
