This is for my Developmental Psychology class.
Write a short explanation on each of Jean Piaget’s stages Sensorimotor, Preoperational, or Concrete Operational: Choose one of Piaget’s stages: Sensorimotor, Preoperational, or Concrete Operational and find a child who is currently in that age range. Observe the child in his or her environment and describe some of the ways in which he or she is exhibiting the developmental phenomena of that stage. Then conduct one or two simple experiments (they can be Piaget’s classic experiments or your own variations) on the child. Record everything that took place, and explain how it exemplifies (or refutes) the phenomena of that stage
