INTASC Principle (2)

     The teacher understands how children learn and develop, and can provide learning opportunities that support their intellectual, social and personal development.

My Energy Transformation Lab, lesson plans found at, is an example of preparing age appropriate lessons using age appropriate materials.  This lab is geared toward middle school and high school students.  According to Jean Piaget's (pronounced pee-ah-jay) theory of cognitive development, these students exceed the age group (ages 7-11) Piaget says are capable of performing the concrete operations required for my Energy Transformation Lab.  Some of those concrete operations are monitoring the caloric loss of each basketball player during the course of a game by keeping track of minutes played.  These are calculations made strictly from physical observations.  More advanced formal operations are not needed.

Before giving the Energy Transformation Lab as an assignment, I always give a homework assignment to locate the nutrition facts label on the reverse side of packaged foods (below).  I always have students bring me labels from various snack items to prove they at least know where to find the caloric value.  Snack foods are generally full of empty calories and would not be MY personal choice for replenishing lost calories, but middle school and high school students are almost certain to be familiar with such junk foods.


I use my Energy Transformation Lab with my students as evidenced on slide two (2) of the following power-point presentation.  My students are recording data, socially interacting, and enjoying a basketball game all at the same time.
