1. Review Piaget’s findings on conservation of volume in pre-operational and in concrete operational children.


  1. Review the video on conservation of liquid volume that was presented in class.


  1. Enlist one child in the pre-operational stage (age 4-5) and one in the concrete operational stage (age7-8). Present the conservation of liquid task as shown on the video. If the younger child proves to not have reached an understanding of conservation, pour the liquid back in the first container in front of the child and repeat the task. If the older child also doesn’t understand conservation yet, pour the liquid back in the first container in front of the child and repeat the task.


  1. Write up a three page typewritten summary of your results and observations (double-spaced, font size 12). Make sure that you demonstrate an understanding of Piaget’s concepts about how a child’s thinking changes over the years. Try to tie your findings in with a broader explanation of child development, by contrasting Piaget’s theory with other theorists. Find at least one other source of information about cognitive development in children and use that source in your summary as well. (Wikipedia does not count as an alternative source). The paper should be divided into a short introduction, a section on observations or findings, and a summary or conclusion section.


  1. Make sure you correctly cite any information taken from the text as well as from any other sources used. Use APA format, i.e. immediately after the cited material you would write: (source, date of publication, page number); e.g. if citing your textbook it would be (Santrock, 2016, p.—).


  1. At the end of the paper, include a list of references using APA format:




Berk, Laura. (2010). Exploring Lifespan Development. Boston: Allyn and Bacon.


Feldman, Robert. (2010). Developmental Psychology. New York: Prentice-Hall.
