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 Alignment

This lesson aligns with the Australian Curriculum for Science, specifically focusing on the chemical sciences content descriptions relating to chemical reactions, properties of substances, and their interactions.

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Chemical Reactions	5 minutes	Briefly introduce the lesson topic, defining chemical reactions and highlighting their importance.
2	Types of Chemical Reactions	10 minutes	Discuss different types: synthesis, decomposition, single replacement, and double replacement. Provide examples.
3	Signs of Chemical Reactions	5 minutes	Explain the signs indicating a chemical reaction: color change, gas production, temperature change, and precipitate formation. Show video clips or images if available.
4	Demonstration	5 minutes	Conduct a safe demonstration of a chemical reaction (vinegar and baking soda). Ensure safety protocols are followed.
5	Interactive Activity	3 minutes	Distribute worksheets for students to fill out based on the demonstration, identifying the type of reaction.
6	Q&A and Wrap Up	2 minutes	Open the floor for any quick questions, summarize key points, and set expectations for homework.

Homework

• Assign students to complete a worksheet identifying everyday chemical reactions they observe at home, including their signs and types.
• Homework will be collected and checked without student presentations in class.

Assessment

• Participation during the lesson and completion of the worksheet will be used to assess understanding of the topic.
