About this Simulation

This simulation models the three states of matter—solid, liquid, and gas—by visualizing how particles behave differently in each state. Learners can observe particle arrangement, movement, and interactions to understand the fundamental properties that distinguish solids from liquids and gases.

Learning objectives: Identify the characteristic properties and particle arrangements of solids, liquids, and gases | Explain how particle motion and spacing differ across the three states of matter | Connect observable macroscopic properties to microscopic particle behavior
