Date: Week 3
Lesson Duration: 45 minutes
Week & Period: Week 3, Period 1
Topic: Energy
Sub-topic: Types of Energy – Potential and Kinetic
Learning Objectives
By the end of the lesson, students should be able to:
Name the types of energy
Define potential and kinetic energy
Give examples of both types
Previous Knowledge
Students already know the meaning and properties of energy
Instructional Materials
Charts showing objects at rest (stone on a hill) and in motion (rolling ball)
A ball, toy car, stretched rubber band
Flashcards with real-life examples
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher shows a ball on the table and asks: “Is the ball using energy now?” Then rolls the ball and asks: “Is it using energy now?” Learners respond. Teacher introduces potential and kinetic energy.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Learners’ Activities (Expanded):
- Learners listen carefully as the teacher explains that energy can be grouped into two types: potential energy (stored energy) and kinetic energy (energy in motion).
- Learners observe practical demonstrations:
- A stretched rubber band is released to show stored energy converting into motion.
- A ball at rest is placed on a table to show potential energy, then pushed to show kinetic energy.
- A toy car is held at the top of a ramp (potential energy) and released to roll down (kinetic energy).
- Learners discuss in pairs or groups and give examples of potential and kinetic energy from their daily lives:
- Potential energy examples: food before eating, water behind a dam, fuel in a car, stretched bow or slingshot, a book on a table
- Kinetic energy examples: flowing water, running child, moving bicycle, swinging pendulum, rolling ball
- Learners perform a mini-experiment in class: place objects (ball, toy car, book) at different heights and observe changes when objects are moved, linking the observations to potential and kinetic energy.
- Learners complete a worksheet where they classify given scenarios as potential or kinetic energy.
Assessment Checks:
- Teacher asks: “When a ball is at rest, what kind of energy does it have?” (Expected answer: Potential energy)
- Teacher asks: “When a car is moving, what kind of energy does it use?” (Expected answer: Kinetic energy)
- Teacher asks learners to give one example of potential energy and one example of kinetic energy from their own environment.
- Teacher observes learners during demonstrations and worksheet activity to ensure understanding.
Notes (Expanded & Detailed):
- Types of energy:
- Potential energy (stored energy): Energy that is stored and ready to do work. Examples:
- Food gives chemical energy to the body.
- Fuel in a car is stored chemical energy.
- Stretched rubber band or bow stores mechanical energy.
- Water at the top of a waterfall has gravitational potential energy.
- A book placed on a table has energy ready to move if pushed.
- Kinetic energy (energy in motion): Energy of a moving object. Examples:
- Flowing river water
- Rolling ball
- Moving bicycle
- Running child
- Swinging pendulum
- Potential energy can transform into kinetic energy. For example, a ball held in hand (potential) rolls down when released (kinetic).
- Energy transformation between potential and kinetic is a common phenomenon in everyday life.
Assignment/Homework:
- Draw two pictures: one showing potential energy and one showing kinetic energy. Label each clearly.
- Write down three examples of potential and kinetic energy you see at home or school.
- Find one activity you do daily where stored energy changes into motion and describe it in two sentences.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Teacher revises definitions of potential and kinetic energy and gives examples. Learners repeat examples.
Evaluation Method (Expanded):
Exit slip/quiz: Learners write one example each of potential and kinetic energy. Teacher will collect slips and provide oral feedback.
Assignment (Expanded):
Draw two examples of potential energy and two examples of kinetic energy.
Follow-up Activity:
Learners act out simple examples of kinetic and potential energy in groups.
Differentiation / Inclusive Strategies
Teacher demonstrates using real objects for visual learners. Learners struggling with writing can draw instead.
