### Simulation: States of Matter and Phase Changes

In this simulation, students will participate in a 10 question quiz. Some questions will challenge students to analyze data to identify the correct state of matter for a specific sample, and then connect the chosen state with an animated particle diagram. In addition, students will examine the behavior of particles in an animated sample as they undergo a phase change, and must correctly identify the change that occurs.
