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...

In this lesson, students will investigate how different materials changed when heated or cooled. The process in developing the investigation will be inquiry based. Students will have the liberty in choosing the materials and devising how...

[Free Registration/Login may be required to access all resource tools.] Freshly baked bread and cherry pie are two delicious parts of any meal. What happens to the ingredients that go into the bread and the pie as they are heated in the...

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

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.

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

In this chemistry lab, students will investigate, observe, and describe a variety of chemical and physical changes in matter. They will understand that this is part of everyday life.

Change variables in this simulation to see how compression affects different states of matter.

This lab serves as a short introduction to both changes in state and air pressure/the gas laws. The students will heat a small amount of water in an aluminum can. They will then invert it in a bucket of cold water and crush the can using...

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.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial, students will begin to understand a substance according to its physical properties. Learn to distinguish between extensive and intensive...

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students identify the chemical properties of a substance and describe chemical changes and differentiate them from physical changes....

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.

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.

In this lesson, students match a substance with its state of matter, identify what state something is, and learn about temporary and permanent changes in matter.

This lesson focuses on Matter including the three states of matter, the energy that it takes to change the state of matter, and experiments for children to conduct. Students can choose to have any paragraph read to them.

Students will use water and cornstarch to make a mystery matter, and then discuss what happens when different energy is applied.

Brief descriptions of physical properties, physical changes, and the process of sublimation. The three states of matter, melting point, and boiling point are described. There is one link on the page, which leads to an explanation of...

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...

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.

Resource provides information about the difference between physical and chemical changes. Includes a definition and examples of each.

Learn how mass is conserved in physical and chemical changes.

Online textbook reviews fundamentals of chemistry and physical science via slideshow presentations, notes, and videos. Materials for classroom activities engage students in inquiry-based, hands-on investigations covering molecular...
