Matter | Review Lesson
Students review the basic concepts of matter, including its definition, states, properties, and common physical and chemical changes. The lesson is designed as a quick, practical refresher for college students with simple guided practice and discussion.
| Term | Definition |

| Matter | Anything that has mass and takes up space. |
| Mass | The amount of matter in an object. |

| Chemical Change | A change that forms a new substance. |
Ask students to write one sentence defining matter and one example from daily life.
Write responses and share a few examples aloud.
Review the definition of matter, then briefly revisit mass, volume, and the three common states of matter using simple examples.
Listen, answer questions, and correct or add to notes.
Show 5 to 6 items or images and ask students to identify whether each is a solid, liquid, or gas and explain why.
Respond verbally or in brief written form.
Present short examples such as melting ice, tearing paper, rusting iron, and burning wood. Ask students to sort each as physical or chemical.
Work with the teacher to classify examples and explain reasoning.
Have students turn to a partner and summarize the most important difference between physical and chemical changes.
Discuss briefly with a partner.
Summarize the key ideas and invite 2 to 3 students to state one concept they remember best.
Share one take-away from the lesson.
End by restating the definition of matter and the key difference between physical and chemical changes. Ask students to name one example of each before class ends.
