Chapter 5. Energy
Chapter Objectives
Students will be able to recognise types of
energy around us as light, electrical, heat
and sound energy and their uses in our
lives.
Topic Objectives
5.1 Energy around Us
Students will be able to;
• Identify different types of energy in daily
life such as light, electricity, heat and
sound.
• List the uses of light, electrical, heat and
sound energy in our daily lives.

• Have students do the activity and ask them to 3
record their findings in the table.
• Advise students to refer to the pictures in the
activity and the character’s talking for their
investigation.
• After that, ask students to discuss how light,
electricity, heat and sound help us based on their
findings as a group. 4

Teacher's Notes
Energy is a word with more than one meaning. In science it is mostly used to describe how much potential a physical
system has to change. In physics, energy is a property of matter. It can be transferred between objects and converted in
any form but it cannot be created or destroyed.
Demonstrating the definition of energy
Students use energy every day of their lives but do not realise that energy enables things to work.
• The definition “energy is the ability to do things” could be demonstrated by using a flashlight. Students know that a
flashlight only works (lights up) when it has batteries in it. Demonstrate by switching on the flashlight without the
battery. At this point students will know that it needs something to make it light therefore you should ask “what does
the flashlight need to make it work?” The answer would be battery obviously.
• You carefully explain that the battery has energy and that this energy enables the flashlight to do something which is to
“light up” when it is switched on. Teacher should demonstrate now with the battery in the flashlight.
, Lesson Objectives Assessment
Students will be able to: Students are able to:
• Define energy. • Explain what energy can do.
• Identify the different types of energy around • Describe how different types of energy such as light,
them. electrical, heat and sound help people.
• Investigate the different kinds of energy with interest.
• Confirm the findings with students.
• Based on their findings, asks the following
5 questions as discussion points.
Q:How can light help us? (Light helps us to
see the things around us, etc.)
Q:How can electricity help us? (Electricity
helps us run electrical appliances, move
something, etc.)
Q:How can heat help us? (Heat makes things
warm, cook food, etc.)
Q:How can sound help us? (Sound helps us to
listen to music, talk or sing, etc.)
• Conclude the discussion.
5 Summary (10 min.)
• Ask the students to open their textbooks to the
summary page and explain it.
• Summarise today’s lesson on the blackboard.
• Ask the following questions as assessment:
Q: What is energy?
Q: What types of energy are there?
Q: What are light, electrical, heat and sound
energy?
Q: Explain how light, electrical, heat and sound
energy work.
• Ask students to copy the notes on the blackboard
into their exercise books.
