Students will add 4 chemicals to a beaker and observe the changes that take place. They will classify them as physical or chemical changes.

Students burn a magnesium strip to reinforce the concepts of chemical vs. physical changes, reaction types, conservation of mass, formulas and equations, stoichiometry, Lewis structures, and to explore the concept of oxidation/reduction...

Do you know the difference between a physical and a chemical change? This interactive tutorial will explore these concepts!

Many materials expand when heated and contract when cooled. What do you think will happen to the elasticity (stretchiness) of a rubber band when it is heated or cooled to various temperatures?

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 lesson is used early in the Chemistry course. The young scholars love it....

[Free Registration/Login may be required to access all resource tools.] Definition of chemical change and examples, signs of chemical change and how it can be reversed.

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.

Young scholars observe reactions of liquids with different known powders in this lesson. Unknown powders are then identified using characteristic chemical changes.Site includes a procedure, teacher instructions, and video instruction.

This lesson focuses on how food packages are designed and made. Students will learn three of the main functions of a food package. They will learn what is necessary of the design and materials of a package to keep food clean, protect or...

In this activity, students will observe another aspect of a chemical change which is a change in temperature. In this reaction, students will experiment with an endothermic reaction.

This activity explores how students could use chemical changes to identify unknown substances. Lab activity includes student and teacher worksheets.

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...

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.

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

This lab illustrates the condition of color change and the formation of gas (bubbles) as a result of a chemical change. Learners will be able to name the characteristics of chemical changes.

Students will create an endothermic chemical reaction by making ice cream. They will observe, describe, and measure the ingredients. After making ice cream, students will measure the temperature of the ice cream and the ice/salt mixture....

Investigate the answers to many commonly asked questions about chemical change. This comprehensive list will address chemical equations and double displacement reactions in addition to other topics.

In this chemistry lab, students will investigate chemical changes that occur when acids and bases react. It is meant to introduce the concepts of chemical changes, gases have mass, conservation of mass, and balancing equations. Students...

Learn to identify changes in matter and explain what happens as matter changes. The lesson is supplemented with several experiments to reinforce key concepts.

This activity introduces students to the complex chemistry of estuarine water. Students investigate how chemical and physical water quality factors-pH, temperature, dissolved oxygen, and salinity-change and interact over varying time...

Learn about matter, its three states, changes of state, how matter behaves, and physical and chemical changes in matter.

[Free Registration/Login Required] Physical and chemical changes are defined and examples are given of each. Practice with determining the difference between mixtures and solutions are also given. Links to external sites for practice...

[Free Registration/Login Required] This unit brings together and consolidates work that children have done before on reversible changes and introduces irreversible changes. Students are guided through experiments illustrating the...

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