Description:

This lesson plan begins with two rectangular pieces of paper -- one forming a cylinder by joining the long sides, the other forming a second cylinder by joining the short sides. Which of these two cylinders will have greater volume? or will they hold the same amount? Students will build a family of cylinders and discover the relation between the dimensions of the generating rectangle and the resulting pair of cylinders. They will also order the cylinders by the amount they hold, and draw a conclusion about the relation between the cylinder's dimensions and the amount it holds. Watch video clips of different classrooms' experiments with this classic conservation problem from Piagetian psychology; see reflections from teachers; read predictions collated from 667 different students.
