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}

Lesson plan

Topic

Le Chatelier's Principle

Objectives

• Understand and explain Le Chatelier’s Principle.
• Apply Le Chatelier’s Principle to predict the effect of changes in concentration, temperature, and pressure on chemical equilibria.
• Conduct a simple demonstration to visualize Le Chatelier’s Principle in action.

Materials

• Whiteboard and markers
• PowerPoint presentation on Le Chatelier's Principle
• Chemical model kits (to demonstrate reactions)
• pH indicators (like litmus paper)
• A clear container with a reversible reaction solution (like colored solutions)
• Handouts summarizing key concepts
• Video clips illustrating Le Chatelier’s Principle (optional)

Grade/Age Group

Grade 11 (16-17 years old)

Subject

Chemistry

Class Size

20 students

National Curriculum Alignment

This lesson aligns with the Next Generation Science Standards (NGSS):

• HS-PS1-5: Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.

Lesson Structure

Step Number	Step Title	Length (minutes)	Details
1	Introduction to the Topic	5	Introduce Le Chatelier’s Principle with an engaging question or scenario related to equilibrium.
2	Presentation of Key Concepts	10	Explain the principle using a PowerPoint presentation. Discuss how it applies to chemical equilibria.
3	Guided Practice	5	Walk through examples of changes in concentration, pressure, and temperature with students.
4	Demonstration	5	Conduct a live demonstration with a chemical reaction (using the colored solution) to show real-time changes.
5	Group Activity	5	Divide students into small groups to discuss hypothetical scenarios and predict outcomes based on Le Chatelier’s Principle.
6	Q&A and Closure	5	Address any questions from students and summarize the key points of the lesson. Assign homework.

Homework

• Complete a worksheet that involves applying Le Chatelier’s Principle to different scenarios without requiring students to present it in class. Collect the worksheets in the next class for review.

Assessment

• Evaluate understanding through student participation during the lesson, group activities, and correctness of homework. Provide individual feedback through the collected worksheets.
