Investigate the changing states of water as you help Steve stay alive while in the Arctic. Includes background information about changing states of matter and about the water cycle, as well as a quiz.

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

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...

This Homewood City Schools site has an outline form and contains lots of information about the classification and composition of matter. Some of the topics covered are matter and temperature, changes in state, composition of matter, and...

Young scholars conduct a hands-on investigation to determine how matter, changing state, effects the property of weight. Students will collect data and graph their results. Resources include step by step instructions, a data worksheet,...

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...

What causes frost to form on the outside of a cold container? In this activity, students will see that the liquid water can change state again and freeze to become ice.

What's the Matter? is a guided inquiry lesson plan on classification of matter, physical and chemical properties, and physical and chemical changes. There are two parts to this lesson plan: (a) concentration game for definitions and (b)...

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.

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?

Use this resource to learn about the three different phases of water; solid, liquid, and gas. What happens to water as it changes into a solid or gas? Includes short and easy to do activity.

[Free Registration/Login Required] An informational text about how cooking causes changes in matter. A question sheet is available to help students build skills in reading comprehension.

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.

Students learn about solids, liquids, and gases in this interactive slide show. Animated cartoon characters explain concepts having to do with properties of matter. A self-checking quiz follows the lesson.

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.

An explanation about the process of evaporation and the conditions needed to complete this process.

This site helps students construct a model of the arrangement of water molecules when present as solid, liquid or gas. Includes background information, lesson plans, links to standards and assessment ideas.

Allow your students to explore states of matter as they learn what causes frost to form on the outside of a cold container. Students will observe how liquid water can change to ice or water vapor in this lab. Lesson includes background...

Observe the changes in the states of matter and volume when a balloon-covered flask with water in it is heated.

For this lesson plan site, students will define matter and compare properties of solids, liquids and gases.

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

Learn how mass is conserved in physical and chemical changes.

Students will learn the difference between physical and chemical properties of matter.
