Students investigate how low temperature causes water vapor to condense into a liquid and then freeze to form a solid.

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...

[Free Registration/Login Required] This flipchart introduces fifth graders to physical and chemical changes in matter. The Law of Conservation of Matter is also covered.

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

The class will go back over the Power Point presentation on chemical and physical properties. The teacher will then conduct numerous liquid nitrogen demos. This instructional activity is used early in the Chemistry course. The students...

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

Join Jacob on the Nova Zembla Expedition, and help him use suitable materials for building his house.

Learn about the phases of matter in this section of a college textbook. Section defines the phases of matter and discusses how to interpret a phase diagram. Also explored is partial pressures and Dalton's Law. Section also includes...

An online flashcard deck that reviews properties of matter. Test your knowledge of matter, chemical changes, and physical changes. Site allows you to put flashcards into two sections, those you know and those you don't. After separating...

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

Join a group of middle-school students on a visit to a laboratory at the Massachusetts Institute of Technology, where they experiment with "mystery mud" and learn about the relationships between magnetism, particle motion, and changes in...

[Free Registration/Login may be required to access all resource tools.] Definition of a change of state and the physical processes that cause it.

In this lesson plan, students will move and generate choreography to understand different states of matter.

The goal of this activity is to develop and use a model to describe that matter is made of particles on a scale that is too small to be seen. You will be making observations of changes supported by a particle model of matter.

Can you distinguish physical changes from chemical reactions? You'll be presented with a number of pictures and asked to identify those which are examples of chemical reactions.

This lesson will describe physical and chemical properties and changes of matter.

Resource provides the ten signs that tell when a chemical change has occured. Each sign has a detailed explanation.

[Free Registration/Login Required] This lesson is the third of three lessons. It covers the physical changes of matter and explains how chemical changes can be detected.

A comprehensive lesson plan site that contains a number of activities to aid in teaching about the states and properties of matter and the difference between a physical and chemical change.

In this activity, students investigate physical and chemical changes in the states of matter for water. They collect data and record their observations.
