Middletown, Middletown, Ohio, 1995, pgs. 41- 46. What should the
students know as a result of this lesson? - Students will state
that elasticity is a physical property - Students will describe
that rubber decreases in length when heated and increases in
length when cooled - Students will describe the effects of
temperature changes on the physical properties - Students will
be able to give a simple explanation related to the change in
length of a rubber band subjected to various temperature changes
What should the students be able to do as a result of this
lesson? - Students will be able to measure differences in length
of rubber bands at different temperatures and relate this to
molecular motion within the polymer strand
