Answer to Question 1

ANS: C
There is a developmental sequence in children's capacity to conserve matter. Children usually grasp conservation of numbers (ages 5 to 6 years) before conservation of substance. Conservation of liquids, mass, and length usually is accomplished at about ages 6 to 7 years, conservation of weight sometime later (ages 9 to 10 years), and conservation of volume or displacement last (ages 9 to 12 years).

Answer to Question 2

ANS: C
Between the ages of 6 and 12 years, children will almost double in weight, increasing 2 to 3 kg (4.4 to 6.6 lb) per year.
