physical growth and motor development
- Look at your height and weight distance curves. Can you see points of apparent transition from a period of faster growth (where the curve is steep) to a period of slower growth (where the curve goes up gradually)? What about transitions from a period of slower growth to a period of faster growth? These are called inflection points. What is the age of each child at the inflection points you identified? Developmentalists often use the term age at takeoffto describe the age at an inflection point marking a transition from slower to faster growth. What is the age at takeoff for any such inflection point on the two distance curves you plotted?
- Look at your two velocity curves. In general, is the rate of growth faster at younger ages or at older ages? What is the basis for your answer? Do you see peaks and valleys in your velocity curves? At what ages? What do the velocity curves show when the distance curves plateau?
- Look at the most pronounced peaks on your velocity curves. Look at the distance curves around the age corresponding to the peak height velocity and the peak weight velocity. What is characteristic of the distance curves at these points?physical growth and motor development
