In this chemistry activity, learners will explore the concept of entropy. When learners stretch and unstretch a balloon, they will notice a change in temperature. This change is caused by the transferal of energy required to change the entropy, or internal disorder, of the material. This is an excellent way to explain a difficult-to-grasp scientific concept.
