Grade: IX Subject: Chemistry Topic: Chemical Equilibrium Time: 45 minutes
Student Learning Outcomes
At the end of this session students will be able to:
-Explain the phenomena of Chemical Equilibrium
-Write a Chemical Reaction for the system at Equilibrium
Required Material
Board, marker, duster, Book, worksheets, video
Motivational Activity (5 minutes)
-The teacher will begin session by formal greetings. After that the teacher will ask some questions from students. These questions are as follows:
-What is meant by equilibrium?
-What are the different types of equilibrium?
-Teacher will write the responses of the students on board
Introductory Activity (14 minutes)
-Teacher will discuss the responses of the students and connect it with the chemical equilibrium
-The teacher will tell students what is Chemical Equilibrium and how to represent a chemical reaction for the system at equilibrium
-Teacher will use different examples of chemical reactions and graph to explain the concept
Activity 1 (6 minutes)
-Teacher will explain the topic by the use of analogy
-Teacher will use the analogy of “Escalator” to explain the chemical equilibrium
Activity 2 (7 minutes)
-Teacher will show a video to students that explains chemical equilibrium by the use of an analogy of “Club” (The link of video is given in the “Reference Material/Resources” portion)
-Then, teacher will discuss the video by getting responses from students that what did they get from the video?
Conclusion (3 minutes)
-Teacher will randomly ask students about the key points of the session
-Then, teacher will summarize the key points of the session
Assessment Activity (10 minutes)
-To assess the understanding of students, teacher will provide a worksheet to students that contains the questions related to chemical equilibrium
-The worksheet is given in appendix “A”
