Piaget's concept of conservation is important to developmental scientists when assessing thinking of preschool and school-age children. Which one of the statements below best illustrates that the child is able to conserve? a. Ricki can reason that if there are 6 red roses and 3 white daises, there are more flowers than roses. b. Rolland knows that if the yellow stick is longer than the green stick, and the green stick is longer than the blue stick, then the yellow stick is longer than the blue stick. c. Ronnie understands that if all muspens eat mlaps, and jorvid is a muspen, then Jorvid must eat mlaps. d. Reina knows that the amount of clay in the ball does not change just because the ball is rolled into a snake shape.

I choose d is that correct

yes

To determine which statement illustrates a child's ability to conserve, we need to understand the concept of conservation as Piaget defined it. Conservation refers to the understanding that certain properties of an object, such as its volume, mass, or number, remain the same even when its appearance changes.

Looking at the given statements:
a. Ricki's statement is about comparing the quantity of flowers and roses, but it does not directly relate to the concept of conservation.
b. Rolland's statement is about comparing the lengths of sticks, but it does not involve conservation.
c. Ronnie's statement is about logical reasoning but does not involve conservation.
d. Reina's statement demonstrates an understanding of conservation. Reina understands that the shape of the object (from a ball to a snake shape) does not change the amount of clay it contains.

Therefore, the correct answer is d. Reina knows that the amount of clay in the ball does not change just because the ball is rolled into a snake shape.
