Which statement accurately describes physical development in preschoolers?

• A. Preschoolers have a lower center of gravity than adults.
• B. Preschoolers' bodies have higher centers of gravity.
• C. Balance improves only when standing still.
• D. Gross motor skills are fully developed by age 3.

Answer: (B)

Center of gravity and balance in preschoolers show how body proportions shape stability. The center of gravity is the point where the body’s mass is concentrated. In preschoolers, this point sits higher than in adults because their heads are relatively large and their torso-to-leg proportions place more mass higher up. A higher center of gravity makes balance more challenging, so preschoolers often adopt wider stances and use their arms to help stay upright, showing more sway during movement or when trying to stand still. As children grow, longer legs and a stronger core move the center of gravity downward toward the pelvis, improving stability and enabling more coordinated gross motor skills. Statements claiming a lower center of gravity, balance only when standing still, or that gross motor skills are fully developed by age 3 don’t fit these developmental changes.
