Introducing Physical and Chemical Changes
Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...
Curated OER
Chemical Changes to Matter
Students analyze the causes of corrosion. In this chemistry lesson, students investigate what is necessary to cause chemical changes in matter. Students discover the causes of rust and tooth decay.

Chemical Change in the Kitchen
Learners examine chemical changes to food. In this chemical changes lesson, students make foods and observe the changes. The changes are recorded in an observation journal. Learners photograph food they make at different stages in the...
Curated OER
Physical and Chemical Changes
Students observe examples of physical changes that can take place between the three states of matter and develop common sense and intuition in distinguishing between chemical and physical changes. They observe diagrams on the board from...
Curated OER
Chemical Changes
Fourth graders examine and identify chemical and physical changes in a variety of substances. They observe a vinegar and baking soda demonstration, and a water, laundry detergent, and Epsom salt mixture demonstration. They discuss the...
I Teach Bio
A Changeable Day
Twenty changes have occurred today, and Dr. Sparks needs help sorting them out! First-time physical science fans simply decide whether each represents a physical or a chemical change. The handout would make a useful quiz or review...
Curated OER
The Nature of Chemical Change: Acting Out an Example
Students identify the signs that a chemical reaction took place. For this chemistry lesson, students role play the movement of different molecules of matter. They classify matter according to their properties.
Curated OER
Physical and Chemical Properties
Students study the difference between physical and chemical properties. They also discuss changes in matter, known as physical and chemical changes. They observe and discuss several demonstrations of both physical and chemical changes
Curated OER
Physical and Chemical Changes
In this changes in matter worksheet, students draw a picture that shows physical and chemical changes. This worksheet has 7 fill in the blank questions.
Curated OER
What is a Chemical Change in Matter?
In this chemical change worksheet, students write down the description of a match before burning and after burning. This worksheet is a graphic organizer.
Curated OER
The Nature of Chemical Change: Acting Out An Example
Young scholars illustrate the molecular nature of matter and show that chemical change involves alteration of molecules.
Curated OER
Physical or Chemical Change
In this matter worksheet, students read statements about changes happening to matter and classify the change as either a physical or a chemical change. This worksheet is a graphic organizer.

Ice Cream Chemical and Physical Changes
Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...
Curated OER
Investigating Chemical and Physical Changes
Students explore physical and chemical changes by looking at how different powders react to a variety of substances. They observe and identify the difference between physical and chemical change using a mystery powder.
Curated OER
States of Matter
Student explore states of matter. In this science lesson plan, students define matter, identify the states of matter, tell about the properties of each state of matter, and demonstrate an understanding of the difference between a...
