United Scientific™ Ensemble Interactives Exploring Entropy Kit

Description

Students are introduced to several fundamental chemistry and physics concepts, like shake, spin, and rattle containers of different particles to investigate relationships between them. This activity teaches the rigorous definition of entropy by grounding it in direct observations related to everyday experiences regarding spontaneity and disorder. By shaking this model of atoms or other microscopic particles, students observe a surprising and highly memorable disorder-to-order transition, which is easily explained through the concepts learned about entropy. The single set includes one container and particles with sides of: 14 and 20. The classroom set includes seven containers and particles with sides of: 14, 20, 12, 10, 8, 6, and 4. The variety of different sized particles allow for greater variations in results and make the group resultsdistinct from each other. Includes activity guide.
