This site provides a lesson plan using candy making to demonstrate physical and chemical changes in matter. Includes directions to make caramel and rock candy.

In these two lessons, students use pretzels and balloons to learn about reversible and non-reversible physical and chemical changes.

Using temperature probes, students will monitor the temperature of melting ice cubes in different situations. This lab activity, allows students to view the procedure and answer questions online that can be saved and evaluated by the...

Find out your or your students' basic knowledge of concepts like matter, molecules and open and closed systems. Afterwards you can see how others answered the questions.

[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...

Explains what a physical change is and gives examples. The difference between a physical and a chemical change is also discussed.

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

[Free Registration/Login Required] Explore how heat and temperature relate to phase changes.

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.

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.

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.

Take on this self-guided advanced level e-text, and learn about the chemical and physical structure of liquids and solids.

Young scholars will use their prior knowledge about changes of matter including physical and chemical changes from the Houghton Mifflin science curriculum. Students will create a hypothesis to test the physical properties of materials...

Science fair project tests whether students can construct a shape out of clay that will float.

[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.

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.

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...
