Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

National Curriculum Correlation

This lesson aligns with the national science curriculum's focus on understanding the principles of chemical reactions and changes.

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Chemical Changes	5 minutes	Briefly explain what chemical changes are and how they differ from physical changes. Provide classroom examples.
2	Discussion of Everyday Examples	5 minutes	In small groups, students discuss and list examples of chemical changes they observe in daily life.
3	Demonstration of Chemical Change	10 minutes	Conduct an experiment by mixing baking soda and vinegar in a bottle, placing a balloon over the opening to capture gas.
4	Observation and Discussion	5 minutes	Allow students to observe the reaction. Discuss what they notice, encouraging them to use scientific terms.
5	Recap and Homework Instructions	5 minutes	Summarize what was learned. Hand out worksheets for homework to reinforce concepts without presentation required.

Homework

• Complete the worksheet that includes definitions, examples, and questions about chemical changes. This should be submitted in the next class without a presentation in front of peers.

Assessment

• Observations of group discussion participation.
• Review of homework for understanding of concepts.
