Markers or chalk
Poster paper
Sticky notes
Various objects representing potential and kinetic energy (e.g., roller
coaster model, ramp and ball, wind-up toy, stretched rubber band, etc.)
Stopwatch or timer
Laptops or tablets (optional)
Procedure:
Introduction (10 minutes)
1. Begin by asking students if they have ever ridden a roller coaster or
played with a toy car. Discuss the excitement and thrill they experienced
during these activities.
2. Write the learning objectives on the board, ensuring students have a
clear understanding of what they will learn.
3. Explain that today they will explore the concepts of potential and kinetic
energy, which are fundamental to understanding the physical world
around us.
Engage: Potential vs. Kinetic Energy Sort (15 minutes)
1. Divide the class into small groups of 3-4 students and provide each
group with a set of sticky notes.
2. On the board, create two columns labeled "Potential Energy" and
"Kinetic Energy."
3. Instruct the groups to brainstorm and write down examples of potential
and kinetic energy on the sticky notes, one example per note.
4. Have the groups take turns placing their sticky notes in the appropriate
column on the board.
5. Discuss and clarify any misconceptions or uncertainties raised during

the activity.
6. Summarize the definitions of potential and kinetic energy based on the
examples provided.
Explore: Energy Conversion Station (20 minutes)
1. Set up different stations in the classroom, each representing a specific
example of potential and kinetic energy. For example: a) Roller coaster
model: Demonstrate how the potential energy of the coaster at the top of
the track is converted into kinetic energy as it descends. b) Ramp and ball:
Show how potential energy is converted into kinetic energy as the ball
rolls down the ramp. c) Wind-up toy: Explain how the potential energy
stored in the toy's wound-up spring is converted into kinetic energy as it
unwinds. d) Stretched rubber band: Demonstrate how potential energy is
converted into kinetic energy when the rubber band is released to propel
an object.
2. Allow students to rotate through each station in small groups, observing
and discussing the conversion of energy at each station.
3. Provide opportunities for students to ask questions and make
connections between the different examples.
4. Encourage students to take notes or draw diagrams to record their
observations and understandings.
Explain: Conservation of Energy Demonstration (15 minutes)
1. Gather the students back together and ask if they noticed any patterns
or similarities in the energy conversions they observed.
2. Introduce the concept of energy conservation, explaining that energy
cannot be created or destroyed but can only change forms.
3. Perform a simple demonstration, such as using a pendulum or a
swinging pendulum toy, to show how potential energy is converted into
kinetic energy and vice versa, without any energy being lost.

4. Discuss the conservation of energy and its implications in various reallife situations.
5. Connect the concept of energy conservation to the examples previously
explored, highlighting how potential and kinetic energy are interconnected
and constantly changing.
Elaborate: Energy Problem-Solving Activity (20 minutes)
1. Distribute a worksheet or digital copy of energy problem-solving
activities to each student.
2. Instruct students to work individually or in pairs to solve the given
problems, which involve calculating potential and kinetic energy or
determining the energy conversions in a given scenario.
3. Encourage students to use the knowledge and examples discussed
earlier to guide their problem-solving process.
4. Circulate around the classroom, providing guidance and support as
needed.
5. After completion, review the answers as a class, discussing the
methods used and reinforcing the correct understanding of potential and
kinetic energy.
Conclusion (5 minutes)
1. Summarize the key points discussed throughout the lesson,
emphasizing the definitions and examples of potential and kinetic energy.
2. Review the concept of energy conservation and its significance.
3. Allow students to ask any final questions or provide feedback on the
lesson.
4. Provide a brief preview of the next lesson or related topics to be
covered.
