Phase	Content	Teaching and Learning Activities		Notes
		Teacher Activities	Student Activities
Introduction/Eliciting Ideas (5 minutes)	Definition of distance, displacement, speed and velocity.	Make connection to students’ prior knowledge on distance, displacement, speed and velocity. (Concept Map)   Elicit students’ ideas by showing the video of 100m sprint event.	Students observe a video of situation involving linear motion and explain about the speed, velocity, and acceleration.	Strategy/Technique: Whole class Q&A Video
Structuring/ Restructuring of Ideas (15 minutes)	Acceleration is the rate of change of velocity.   Acceleration = Change of velocity/ time taken = (final velocity-initial velocity) / time taken	Show a car with speedometer.   Ask two central guiding questions:   How does acceleration relate to change of velocity?   How does acceleration relate to change of time?   Show a car stops at T-junction and asks students to predict what happens to the velocity of the car when it’s arrives the T-junction.   Show four different picture of the car with different direction of motion, velocity, and acceleration.   Show ticker tape timer and explain about the velocity and acceleration of the trolley.   Show one example to solve problem question.	Students make prediction, inference, observation.       Students make prediction and conclusion about the acceleration of the car.	Strategy/Technique: Graphics by teacher           Resources: PP slides
Application of Ideas (5 minutes)	One problem involving the use of a = v-u         t	Show problem on slides. (refer to Appendix 1)	Students solve problems in groups.   Students present their solutions by writing on the whiteboard.	Strategy/ Techniques Group discussion.   Resources: PP slides
Reflection/ Closure (5 minutes)	Acceleration is the rate of change of velocity.   Acceleration = Change of velocity/ time taken = (final velocity-  initial velocity) / time taken	Show learning outcomes.   Relate the topic to the next topic.   Give reading assignment on Analysing Motion Graph for next lesson.   Written problem solving using a=v-u       t                     in exercise book.	Students conclude the lesson by verbally stating the main ideas and relating to their initial ideas.	Strategy/Techniques: Whole class Q&A   Resources: PP slides
