Molecular Motion Model
Operation: Visitors press the button to observe the motion state of molecules (or balls). Scientific Principle: Classical physics holds that any substance will exhibit three states due to changes in temperature and external pressure: solid, liquid, and gas. This exhibit uses changes in air pressure and airflow within a container to simulate molecular motion during substance changes and its influence by temperature.
