This two-part lesson explores chemical change using Winogradsky Columns. Part 1 constructs student concepts concerning chemical and physical changes. Part 2 asks young scholars to compare physical versus chemical changes and observe...

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

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

A module that provides the definition of chemical property and examples of the chemical properties of matter using explanations, pictures, and review questions.

This resource lists the different types of chemical reactions and gives examples of chemical changes that are seen in everyday life.

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?

Engaging hands-on science lessons for grades 2-6 on chemical and physical changes.

Help solve the mystery and find the missing crystal. Following the activity, read more about chemical and physical changes, and then take a quick quiz to check for understanding.

In this classroom lab, students will investigate the characteristics of a chemical change. Students will also provide a definition of what constitutes a physical change through observation of several examples. Students will use/create...

[Free Registration/Login may be required to access all resource tools.] Covers reversible and nonreversible changes.

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

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

After observing a demonstration of a chemical reaction between a burning candle and the oxygen in the air, students use atom model cut-outs to model the reaction and see that all the atoms in the reactants show up in the products.

In this lesson, students learn about physical and chemical changes during digestion through a variety of activities.

Explains the difference between chemical and physical 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....

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

Brief descriptions of physical properties, physical changes, and the process of sublimation. The three states of matter, melting point, and boiling point are described. There is one link on the page, which leads to an explanation of...

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

In this experiment, three reactions are performed in a sealed Ziploc bag so that they can be observed. Students identify whether physical or chemical change has taken place.

Students are given a scenario for this lesson plan where they must use investigative skills like a detective would to decide whether changes that happen to objects in the story are physical or chemical. They then conduct an experiment...
