Middle School Chemistry: Changing State: Melting
Discover the concept that energy transfer and molecular motion cause the change in state from a solid to a liquid. Also compare state changes of water to the state changes of other substances.
Florida State University
Florida State University: Intermolecular Forces: Changes of State
Discusses the changes of state that can occur for the three different types of matter (solids, liquids, and gases) and different types of heat energy that have been defined by scientists.

Utah Science: Changing Matter
Matter changes both physically and chemically on a fairly regular basis. Through these activities students will challenge their understanding of the changes that may take place with different types of matter.
University of Colorado
University of Colorado: Ph Et Interactive Simulations: University of Colorado: States of Matter: Basics
An interactive simulation will heat, cool and compress atoms and molecules. Watch as they change between solid, liquid and gas phases. Recognize that different substances have different properties which will affect the temperatures for...
University of Colorado
University of Colorado: Ph Et Interactive Simulations: States of Matter: Basics
After watching this simulation, students will be able to describe characteristics of the three states of matter. They will watch as atoms and molecules change between solid, liquid and gas phases.
Concord Consortium
Concord Consortium: Stem Resources: States of Matter
Using simulations observe what solids, liquids, and gases look like at the atomic scale. After observing the different states of matter at their atomic level, students will be able to conclude about the forces and attractions that exist...
Scholastic
Scholastic: Dirtmeister's Science Lab: Matter
Students will use water and cornstarch to make a mystery matter, and then discuss what happens when different energy is applied.
