A series of interactive applets use scientific models to teach some basic concepts of matter, including states of matter and physical and chemical changes.

Learners 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.

Matter is anything that has mass and occupies a space. In this site you will find a lot of illustrations and interactive activities dealing with matter.

A tutorial reviewing the states of matter and the effects of heating and cooling matter in the different states. (Note: some of the links may not load in the archived version of the site.)

Students use the EasyTemp temperature probe to determine temperature changes as different solid substances dissolve in water. They then develop and test a plan for making the best cold pack using three grams of one of the substances....

A released question from the Trends in International Mathematics and Science Study (TIMSS) assessment about change of states of matter. Also included is a scoring guide for the released question.

In this site you can learn and experiment with matter properties and change in behavior. Every theoretical explanation is accompanied by an animation. You will be able to aply the theory to real experiments.

This tutorial helps students understand the Kinetic Theory, which explains the effects of temperature and pressure on matter as it goes through phase changes.

A video and a short quiz on the periodic table of elements and how it is organized.

A lesson plan using dry ice to show the four states of matter. Included are inquiry-based questions to use as part of the demonstration.

Find out how water can exist in the three different pahses of matter.

Learn how states of matter are dependent on an object's average kinetic energy.

[Free Registration/Login Required] This flipchart is a lesson covering four of the five states of matter. It includes several assessment questions.

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

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?

[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.

The heat of vaporization along with several other thermal properties are explained. Sample problems are given. Illustrations.

Young scholars observe a molecular dance of bursting colors through exploring states of matter and learning that materials can be characterize by how they respond to water.

Students are introduced to the similarities and differences in the behaviors of elastic solids and viscous fluids. Several types of fluid behaviors are described--Bingham plastic, Newtonian, shear thinning and shear thickening--along...

Investigate states of matter while making ice cream. Explore how to turn a liquid into a solid by removing heat energy.

This lesson plan focuses on the difference between physical and chemical changes of matter.

Explore properties of matter by making a slimy substance out of cornstarch and water then noticing how it reacts to pressure.

A brief site which defines solids, liquids and gases along with a drawing of each.

Explore the properties of colloids while making putty. Discover how some mixtures can display properties of both solids and liquids.
