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...

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.

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...

Students will be expanding a study of phase changes after experiences with exploration of the three phases of matter. They apply what they have learned through freezing water and create a tasty ice cream treat.

This activity reviews of states of matter, then relates them to atomic movement as it is affected by attractions between atoms and the addition of energy. Latent heat and evaporative cooling are also topics covered. Multiple-choice and...

Learn how states of matter can change as heat is added to a system.

In this series of chemistry labs, students learn about the three states of matter by observing how molecules contract or expand as they change state.

Help the Phantom choose a material and observe the changes at different temperatures in the molecule chamber. What happens to the elements or molecules as the temperature changes?

Four activities for reviewing vocabulary and definitions related to changes in states of matter.

In the States of Matter module, students further explore the concept that anything on earth that has mass and takes up space is matter. This exercise introduces students to solids, liquids and gases, the three most common states of...

[Free Registration/Login Required] Explore this interactive by dragging the red dots to match each physical state of water with the correct picture of its molecules.

Often we find that different phases of pure substances can exist in equilibrium with one another. Let us consider an important gedankenexperiment (Latin-German for "thought experiment") in which we boil water. Ordinary water boiling is...

Students investigate the structure and parts of the atom, and learn about atomic mass and atomic number. They also explore the differences among solids, liquids, gases, and plasma.

[Free Registration/Login Required] Explore how heat and temperature relate to phase changes.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will define a mixture and understand why mixtures are different than pure substances. They will classify mixtures as homogeneous or...

Five exemplary chemistry lessons about the three states of matter complete with handouts and animations.

[Free Registration/Login Required] In this interactive you will move the red dot below each flask to observe how particles move in each different phase of water. You will need a sign-in to access this media, but it will be well worth...

Five chemistry lessons about phase changes between the states of mattter complete with handouts and animations.

Printable classroom-ready worksheets for a series of simple-to-implement experiments about the states of matter.

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.

Given descriptions, scenarios, or illustrations, students will distinguish between the compressibility, structure, shape, and volume of solids, liquids, and gases.

A discussion of the variety of forces which hold molecules together. The relative strengths of these forces for the various states of matter is discussed. The effect of such forces on the boiling points and other phase change...

At this resource discover the difference between solids, liquids, and gases. Practice what you just learned with included review questions.

Wikipedia offers a brief description of the term, "Melting point," including hyperlinked terms.
