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. Students 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.

For this lesson, 5th graders explore how to use tableaux to dramatize physical and chemical changes, and add dialogue to the tableaux to support their argument of whether the change is physical or chemical.

Explains what a chemical change is and how to identify one. Provides examples of chemical changes that are often seen in organic and inorganic compounds.

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

[Free Registration/Login may be required to access all resource tools.] Students will compare theoretical yield to actual yield, and then investigate what happens when one reactant runs out before the other reactants are fully consumed....

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

[Free Registration/Login may be required to access all resource tools.] Provides the definitions of physical and chemical changes in matter and gives examples. The law of conservation of mass is also described.

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)...

Students will use their prior knowledge about changes of matter to develop a hypothesis to test the physical properties of materials such as plastic (polymers) and how its chemical properties allow it to have unique physical properties.

Young scholars will complete various tests of five mystery powders to develop an understanding of physical and chemical properties. They will record their observations and develop hypotheses as to what they think each mystery powder is...

Learn about color change and pH as it relates to chemical changes.

Learn about absorption in this hands-on science experiment. Includes full list of materials, procedures, and scientific explanation of what happens to different types of beans as they soak in water in a test vial.
