Start the lesson by discussing everyday examples of physical and chemical changes, like chopping wood and burning it. Highlight how these changes are part of students' daily lives.

Introduce the concept of chemical changes with a quick demonstration, such as mixing baking soda and vinegar to produce gas bubbles.

Explain the differences between physical and chemical changes, using examples like melting ice and rusting iron.

Discuss the characteristics of chemical reactions, including the formation of new substances and energy release.

Watch the video on reversible and irreversible changes to matter to understand how different processes affect matter.

Engage students in a discussion about the evidence of chemical changes, such as color change and gas production.

Conduct an experiment where students mix baking soda and vinegar to observe the production of gas as evidence of a chemical change.

Use the 'Chemical Change – Bicarbonate Soda and Vinegar' video to support the activity and explain the reaction process.

Have students identify examples of chemical changes in their environment, such as rusting metal or baking bread.

Assign the 'Chemical Change' assessment to reinforce understanding of chemical reactions and their characteristics.

Conduct a quick quiz to assess students' ability to distinguish between physical and chemical changes.

Review students' observations and conclusions from the hands-on activity to ensure comprehension.

Encourage students to reflect on what they learned about chemical changes and how they can identify them in real life.

Discuss the irreversible nature of most chemical changes and the implications for everyday life.

Use the 'Mass and Volume' assessment to explore related concepts and reinforce understanding of matter properties.

Encourage students to explore further by researching other examples of chemical changes in nature and technology.
